Podcasts about oligocene

Listen in as Real Science Radio host Fred Williams and co-host Doug McBurney review and update some of Bob Enyart's legendary list of not so old things! From Darwin's Finches to opals forming in months to man's genetic diversity in 200 generations, to carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations simply defy the claim that the earth is billions of years old. Real science demands the dismissal of the alleged million and billion year ages asserted by the ungodly and the foolish.     * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner.  * Finches Speciate in Two Generations vs Two Million Years for Darwin's Birds?  Darwin's finches on the Galapagos Islands are said to have diversified into 14 species over a period of two million years. But in 2017 the journal Science reported a newcomer to the Island which within two generations spawned a reproductively isolated new species. In another instance as documented by Lee Spetner, a hundred birds of the same finch species introduced to an island cluster a 1,000 kilometers from Galapagos diversified into species with the typical variations in beak sizes, etc. "If this diversification occurred in less than seventeen years," Dr. Spetner asks, "why did Darwin's Galapagos finches [as claimed by evolutionists] have to take two million years?" * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks. See this also from creationists by a geologist, a paleobiochemist, and a nuclear chemist. * Blue Eyes Originated Not So Long Ago: Not a million years ago, nor a hundred thousand years ago, but based on a peer-reviewed paper in Human Genetics, a press release at Science Daily reports that, "research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today." * Adding the Entire Universe to our List of Not So Old Things? Based on March 2019 findings from Hubble, Nobel laureate Adam Riess of the Space Telescope Science Institute and his co-authors in the Astrophysical Journal estimate that the universe is about a billion years younger than previously thought! Then in September 2019 in the journal Science, the age dropped precipitously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things!   * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T. Rex, hadrosaur, titanosaur, triceratops, Lufengosaur, mosasaur, and Archaeopteryx, and many others dated, allegedly, even hundreds of millions of years old, have yielded their endogenous, still-soft biological material. See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including: - in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa.   - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations! The journal Nature reports The Recent Origin of Most Human Protein-coding Variants. As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts. - The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies evolving too quickly,

-- Finches Diversify in Decades, Opals Form in Months,  Man's Genetic Diversity in 200 Generations, C-14 Everywhere: Real Science Radio hosts Bob Enyart and Fred Williams present their classic program that led to the audience-favorites rsr.org/list-shows! See below and hear on today's radio program our list of Not So Old and Not So Slow Things! From opals forming in months to man's genetic diversity in 200 generations, and with carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations fill the guys' most traditional list challenging those who claim that the earth is billions of years old. Many of these scientific finds demand a re-evaluation of supposed million and billion-year ages. * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner. * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks.

Then in September 2019 in the journal Science, the age dropped precipitiously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things!   * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T.

See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including:- in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa.   - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations!

"You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts.- The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies evolving too quickly, galaxy clusters, and even human feet (which, like Mummy DNA, challenge the Out of Africa paradigm), jellyfish have gotten into the act squeezing evolution's timeline, here by 200 million years when they were found in strata allegedly a half-a-billion years old. Other examples, ironically referred to as Medusoid Problematica, are even found in pre-Cambrian strata. - 171 tadpoles of the same species buried in diatoms. - Leaves buried vertically through single-celled diatoms powerfully refute the claimed super-slow deposition of diatomaceous rock. - Many fossils, including a Mesosaur, have been buried in multiple "varve" layers, which are claimed to be annual depositions, yet they show no erosional patterns that would indicate gradual burial (as they claim, absurdly, over even thousands of years). - A single whale skeleton preserved in California in dozens of layers of diatom deposits thus forming a polystrate fossil. - 40 whales buried in the desert in Chile. "What's really interesting is that this didn't just happen once," said Smithsonian evolutionist Dr. Nick Pyenson. It happened four times." Why's that? Because "the fossil site has at least four layers", to which Real Science Radio's Bob Enyart replies: "Ha ha ha ha ha ha ha ha ha ha ha", with RSR co-host Fred Williams thoughtfully adding, "Ha ha!" * Polystrate Trees: Examples abound around the world of polystrate trees:  - Yellowstone's petrified polystrate forest (with the NPS exhibit sign removed; see below) with successive layers of rootless trees demonstrating the rapid deposition of fifty layers of strata. - A similarly formed polystrate fossil forest in France demonstrating the rapid deposition of a dozen strata. - In a thousand locations including famously the Fossil Cliffs of Joggins, Nova Scotia, polystrate fossils such as trees span many strata. - These trees lack erosion: Not only should such fossils, generally speaking, not even exist, but polystrates including trees typically show no evidence of erosion increasing with height. All of this powerfully disproves the claim that the layers were deposited slowly over thousands or millions of years. In the experience of your RSR radio hosts, evolutionists commonly respond to this hard evidence with mocking. See CRSQ June 2006, ICR Impact #316, and RSR 8-11-06 at KGOV.com. * Yellowstone Petrified Trees Sign Removed: The National Park Service removed their incorrect sign (see left and more). The NPS had claimed that in dozens of different strata over a 40-square mile area, many petrified trees were still standing where they had grown. The NPS eventually removed the sign partly because those petrified trees had no root systems, which they would have had if they had grown there. Instead, the trees of this "fossil forest" have roots that are abruptly broken off two or three feet from their trunks. If these mature trees actually had been remnants of sequential forests that had grown up in strata layer on top of strata layer, 27 times on Specimen Ridge (and 50 times at Specimen Creek), such a natural history implies passage of more time than permitted by biblical chronology. So, don't trust the National Park Service on historical science because they're wrong on the age of the Earth. * Wood Petrifies Quickly: Not surprisingly, by the common evolutionary knee-jerk claim of deep time, "several researchers believe that several millions of years are necessary for the complete formation of silicified wood". Our List of Not So Old and Not So Slow Things includes the work of five Japanese scientists who proved creationist research and published their results in the peer-reviewed journal Sedimentary Geology showing that wood can and does petrify rapidly. Modern wood significantly petrified in 36 years these researchers concluded that wood buried in strata could have been petrified in "a fairly short period of time, in the order of several tens to hundreds of years." * The Scablands: The primary surface features of the Scablands, which cover thousands of square miles of eastern Washington, were long believed to have formed gradually. Yet, against the determined claims of uniformitarian geologists, there is now overwhelming evidence as presented even in a NOVA TV program that the primary features of the Scablands formed rapidly from a catastrophic breach of Lake Missoula causing a massive regional flood. Of course evolutionary geologists still argue that the landscape was formed over tens of thousands of years, now by claiming there must have been a hundred Missoula floods. However, the evidence that there was Only One Lake Missoula Flood has been powerfully reinforced by a University of Colorado Ph.D. thesis. So the Scablands itself is no longer available to old-earthers as de facto evidence for the passage of millions of years. * The Heart Mountain Detachment: in Wyoming just east of Yellowstone, this mountain did not break apart slowly by uniformitarian processes but in only about half-an-hour as widely reported including in the evolutionist LiveScience.com, "Land Speed Record: Mountain Moves 62 Miles in 30 Minutes." The evidence indicates that this mountain of rock covering 425 square miles rapidly broke into 50 pieces and slid apart over an area of more than 1,300 square miles in a biblical, not a "geological," timeframe.  * "150 Million" year-old Squid Ink Not Decomposed: This still-writable ink had dehydrated but had not decomposed! The British Geological Survey's Dr. Phil Wilby, who excavated the fossil, said, "It is difficult to imagine how you can have something as soft and sloppy as an ink sac fossilised in three dimensions, still black, and inside a rock that is 150 million years old." And the Daily Mail states that, "the black ink was of exactly the same structure as that of today's version", just desiccated. And Wilby added, "Normally you would find only the hard parts like the shell and bones fossilised but... these creatures... can be dissected as if they are living animals, you can see the muscle fibres and cells. It is difficult to imagine... The structure is similar to ink from a modern squid so we can write with it..." Why is this difficult for evolutionists to imagine? Because as Dr. Carl Wieland writes, "Chemical structures 'fall apart' all by themselves over time due to the randomizing effects of molecular motion."Decades ago Bob Enyart broadcast a geology program about Mount St. Helens' catastrophic destruction of forests and the hydraulic transportation and upright deposition of trees. Later, Bob met the chief ranger from Haleakala National Park on Hawaii's island of Maui, Mark Tanaka-Sanders. The ranger agreed to correspond with his colleague at Yellowstone to urge him to have the sign removed. Thankfully, it was then removed. (See also AIG, CMI, and all the original Yellowstone exhibit photos.) Groundbreaking research conducted by creation geologist Dr. Steve Austin in Spirit Lake after Mount St. Helens eruption provided a modern-day analog to the formation of Yellowstone fossil forest. A steam blast from that volcano blew over tens of thousands of trees leaving them without attached roots. Many thousands of those trees were floating upright in Spirit Lake, and began sinking at varying rates into rapidly and sporadically deposited sediments. Once Yellowstone's successive forest interpretation was falsified (though like with junk DNA, it's too big to fail, so many atheists and others still cling to it), the erroneous sign was removed. * Asiatic vs. European Honeybees: These two populations of bees have been separated supposedly for seven million years. A researcher decided to put the two together to see what would happen. What we should have here is a failure to communicate that would have resulted after their "language" evolved over millions of years. However, European and Asiatic honeybees are still able to communicate, putting into doubt the evolutionary claim that they were separated over "geologic periods." For more, see the Public Library of Science, Asiatic Honeybees Can Understand Dance Language of European Honeybees. (Oh yeah, and why don't fossils of poorly-formed honeycombs exist, from the millions of years before the bees and natural selection finally got the design right? Ha! Because they don't exist! :) Nautiloid proves rapid limestone formation. * Remember the Nautiloids: In the Grand Canyon there is a limestone layer averaging seven feet thick that runs the 277 miles of the canyon (and beyond) that covers hundreds of square miles and contains an average of one nautiloid fossil per square meter. Along with many other dead creatures in this one particular layer, 15% of these nautiloids were killed and then fossilized standing on their heads. Yes, vertically. They were caught in such an intense and rapid catastrophic flow that gravity was not able to cause all of their dead carcasses to fall over on their sides. Famed Mount St. Helens geologist Steve Austin is also the world's leading expert on nautiloid fossils and has worked in the canyon and presented his findings to the park's rangers at the invitation of National Park Service officials. Austin points out, as is true of many of the world's mass fossil graveyards, that this enormous nautiloid deposition provides indisputable proof of the extremely rapid formation of a significant layer of limestone near the bottom of the canyon, a layer like the others we've been told about, that allegedly formed at the bottom of a calm and placid sea with slow and gradual sedimentation. But a million nautiloids, standing on their heads, literally, would beg to differ. At our sister stie, RSR provides the relevant Geologic Society of America abstract, links, and video. *  Now It's Allegedly Two Million Year-Old Leaves: "When we started pulling leaves out of the soil, that was surreal, to know that it's millions of years old..." sur-re-al: adjective: a bizarre mix of fact and fantasy. In this case, the leaves are the facts. Earth scientists from Ohio State and the University of Minnesota say that wood and leaves they found in the Canadian Arctic are at least two million years old, and perhaps more than ten million years old, even though the leaves are just dry and crumbly and the wood still burns! * Gold Precipitates in Veins in Less than a Second: After geologists submitted for decades to the assumption that each layer of gold would deposit at the alleged super slow rates of geologic process, the journal Nature Geoscience reports that each layer of deposition can occur within a few tenths of a second. Meanwhile, at the Lihir gold deposit in Papua New Guinea, evolutionists assumed the more than 20 million ounces of gold in the Lihir reserve took millions of years to deposit, but as reported in the journal Science, geologists can now demonstrate that the deposit could have formed in thousands of years, or far more quickly! Iceland's not-so-old Surtsey Island looks ancient. * Surtsey Island, Iceland: Of the volcanic island that formed in 1963, New Scientist reported in 2007 about Surtsey that "geographers... marvel that canyons, gullies and other land features that typically take tens of thousands or millions of years to form were created in less than a decade." Yes. And Sigurdur Thorarinsson, Iceland's chief  geologist, wrote in the months after Surtsey formed, "that the time scale," he had been trained "to attach to geological developments is misleading." [For what is said to] take thousands of years... the same development may take a few weeks or even days here [including to form] a landscape... so varied and mature that it was almost beyond belief... wide sandy beaches and precipitous crags... gravel banks and lagoons, impressive cliffs… hollows, glens and soft undulating land... fractures and faultscarps, channels and screes… confounded by what met your eye... boulders worn by the surf, some of which were almost round... -Iceland's chief geologist * The Palouse River Gorge: In the southeast of Washington State, the Palouse River Gorge is one of many features formed rapidly by 500 cubic miles of water catastrophically released with the breaching of a natural dam in the Lake Missoula Flood (which gouged out the Scablands as described above). So, hard rock can be breached and eroded rapidly. * Leaf Shapes Identical for 190 Million Years?  From Berkley.edu, "Ginkgo biloba... dates back to... about 190 million years ago... fossilized leaf material from the Tertiary species Ginkgo adiantoides is considered similar or even identical to that produced by modern Ginkgo biloba trees... virtually indistinguishable..." The literature describes leaf shapes as "spectacularly diverse" sometimes within a species but especially across the plant kingdom. Because all kinds of plants survive with all kinds of different leaf shapes, the conservation of a species retaining a single shape over alleged deep time is a telling issue. Darwin's theory is undermined by the unchanging shape over millions of years of a species' leaf shape. This lack of change, stasis in what should be an easily morphable plant trait, supports the broader conclusion that chimp-like creatures did not become human beings and all the other ambitious evolutionary creation of new kinds are simply imagined. (Ginkgo adiantoides and biloba are actually the same species. Wikipedia states, "It is doubtful whether the Northern Hemisphere fossil species of Ginkgo can be reliably distinguished." For oftentimes, as documented by Dr. Carl Werner in his Evolution: The Grand Experiment series, paleontogists falsely speciate identical specimens, giving different species names, even different genus names, to the fossil and living animals that appear identical.) * Box Canyon, Idaho: Geologists now think Box Canyon in Idaho, USA, was carved by a catastrophic flood and not slowly over millions of years with 1) huge plunge pools formed by waterfalls; 2) the almost complete removal of large basalt boulders from the canyon; 3) an eroded notch on the plateau at the top of the canyon; and 4) water scour marks on the basalt plateau leading to the canyon. Scientists calculate that the flood was so large that it could have eroded the whole canyon in as little as 35 days. See the journal Science, Formation of Box Canyon, Idaho, by Megaflood, and the Journal of Creation, and Creation Magazine. * Manganese Nodules Rapid Formation: Allegedly, as claimed at the Wikipedia entry from 2005 through 2021: "Nodule growth is one of the slowest of all geological phenomena – in the order of a centimeter over several million years." Wow, that would be slow! And a Texas A&M Marine Sciences technical slide presentation says, “They grow very slowly (mm/million years) and can be tens of millions of years old", with RWU's oceanography textbook also putting it at "0.001 mm per thousand years." But according to a World Almanac documentary they have formed "around beer cans," said marine geologist Dr. John Yates in the 1997 video Universe Beneath the Sea: The Next Frontier. There are also reports of manganese nodules forming around ships sunk in the First World War. See more at at youngearth.com, at TOL, in the print edition of the Journal of Creation, and in this typical forum discussion with atheists (at the Chicago Cubs forum no less :). * "6,000 year-old" Mitochondrial Eve: As the Bible calls "Eve... the mother of all living" (Gen. 3:20), genetic researchers have named the one woman from whom all humans have descended "Mitochondrial Eve." But in a scientific attempt to date her existence, they openly admit that they included chimpanzee DNA in their analysis in order to get what they viewed as a reasonably old date of 200,000 years ago (which is still surprisingly recent from their perspective, but old enough not to strain Darwinian theory too much). But then as widely reported including by Science magazine, when they dropped the chimp data and used only actual human mutation rates, that process determined that Eve lived only six thousand years ago! In Ann Gibbon's Science article, "Calibrating the Mitochondrial Clock," rather than again using circular reasoning by assuming their conclusion (that humans evolved from ape-like creatures), they performed their calculations using actual measured mutation rates. This peer-reviewed journal then reported that if these rates have been constant, "mitochondrial Eve… would be a mere 6000 years old." See also the journal Nature and creation.com's "A shrinking date for Eve," and Walt Brown's assessment. Expectedly though, evolutionists have found a way to reject their own unbiased finding (the conclusion contrary to their self-interest) by returning to their original method of using circular reasoning, as reported in the American Journal of Human Genetics, "calibrating against recent evidence for the divergence time of humans and chimpanzees,"  to reset their mitochondrial clock back to 200,000 years. * Even Younger Y-Chromosomal Adam: (Although he should be called, "Y-Chromosomal Noah.") While we inherit our mtDNA only from our mothers, only men have a Y chromosome (which incidentally genetically disproves the claim that the fetus is "part of the woman's body," since the little boy's y chromosome could never be part of mom's body). Based on documented mutation rates on and the extraordinary lack of mutational differences in this specifically male DNA, the Y-chromosomal Adam would have lived only a few thousand years ago! (He's significantly younger than mtEve because of the genetic bottleneck of the global flood.) Yet while the Darwinian camp wrongly claimed for decades that humans were 98% genetically similar to chimps, secular scientists today, using the same type of calculation only more accurately, have unintentionally documented that chimps are about as far genetically from what makes a human being a male, as mankind itself is from sponges! Geneticists have found now that sponges are 70% the same as humans genetically, and separately, that human and chimp Y chromosomes are  "horrendously" 30%

The gang discusses two papers that looks at mammal jaws and teeth. The first paper uses many different analyses to study how the mammal jaw evolved, and the second paper looks at a unique set of teeth in a fossil whale group. Meanwhile, Curt gets ideas from Mortal Kombat, James has discusses farming practices, and Amanda finds any excuse to be fabulous.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at how mouths for animals with hair have changed over time. The first paper looks at the bottom hard part of the mouth to see how it first started and how it has changed and why it changed. Lots of people have ideas about this, but this paper is the first attempt to really look at this problem for a lot of different ways of handling it. They do a lot of things that are very number heavy to look at how these hard parts are able to move, and they look at a lot of parts from living and long dead things. What they find is that the bottom mouth parts of animals with hair are not as good as we thought. They are hard so they do not break, but other animals have bottom mouth parts that are easier to use and quicker. Because animals with hair make their bottom mouth from just one hard part, it may have made it easier for them to get many different teeth in the mouth. This is a story that has a lot more parts than just, "animals with hair had better everything so that is why there are now a lot of them" and instead shows that some changes were not "better" but may have opened doors to other ways to use a mouth (like many different teeth in the same mouth).   The second paper looks at one animal with hair that moves through the water and has some very weird teeth that push out the front of the mouth. But first, the paper needs to see if these are really teeth. Some long teeth like things are found in other animals with hair, but these long things do not have all the parts to be teeth. When they look at this animal, they see that these are actually really long teeth. This is interesting because teeth can be more hurt by things than the long teeth like things. So if these are teeth, what did they do with them? They do not have breaks and they would not be good for moving through the ground looking for food, so the people who wrote the paper think they might be used to cut food.   References: Tseng, Z.

The earliest known fossil earless seal is Noriphoca gaudini from the late Oligocene or earliest Miocene (Aquitanian) of Italy.[1] Other early fossil phocids date from the mid-Miocene, 15 million years ago in the north Atlantic.[1][3] Until recently, many researchers believed that phocids evolved separately from otariids and odobenids; and that they evolved from otter-like animals, such as Potamotherium, which inhabited European freshwater lakes. Recent evidence strongly suggests a monophyletic origin for all pinnipeds from a single ancestor, possibly Enaliarctos, most closely related to the mustelids and bears.[4]Monk seals and elephant seals were previously believed to have first entered the Pacific through the open straits between North and South America,[5] with the Antarctic true seals either using the same route or travelled down the west coast of Africa.[6] It is now thought that the monk seals, elephant seals, and Antarctic seals all evolved in the southern hemisphere, and likely dispersed to their current distributions from more southern latitudes.[7]

Mountain gorillas are descendants of ancestral monkeys and apes found in Africa and Arabia during the start of the Oligocene epoch (34–24 million years ago). The fossil record provides evidence of the hominoid primates (apes) found in east Africa approximately 22–32 million years ago. The fossil record of the area where mountain gorillas live is particularly poor and so its evolutionary history is not clear.[5]It was about 8.8 to 12 million years ago that the group of primates who were to evolve into gorillas split from their common ancestor with humans and chimps; this is when the genus Gorilla emerged. Mountain gorillas have been isolated from eastern lowland gorillas for approximately 10,000 years and these two taxa separated from their western counterparts approximately 1.2 to 3 million years ago.[6] The genus was first referenced as Troglodytes in 1847, but renamed to Gorilla in 1852. It was not until 1967 that the taxonomist Colin Groves proposed that all gorillas be regarded as one species (Gorilla gorilla) with three subspecies Gorilla gorilla gorilla (western lowland gorilla), Gorilla gorilla graueri (lowland gorillas found west of the Virungas) and Gorilla gorilla beringei (mountain gorillas, including Gorilla beringei, found in the Virungas and Bwindi). In 2003, after a review, they were divided into two species (Gorilla gorilla and Gorilla beringei) by The World Conservation Union (IUCN).[5] There is now agreement that there are two species, each with two subspecies.[7]Be sure to use code: HERDSODA at drinkolipop.com and save 15% on all orders!

From opals forming in months to man's genetic diversity in 200 generations, and with carbon 14 everywhere it's not supposed to be (including in diamonds and dinosaur bones!), scientific observations fill the guys' most traditional list challenging those who claim that the earth is billions of years old. Many of these scientific finds demand a re-evaluation of supposed million and billion-year ages. * Finches Adapt in 17 Years, Not 2.3 Million: Charles Darwin's finches are claimed to have taken 2,300,000 years to diversify from an initial species blown onto the Galapagos Islands. Yet individuals from a single finch species on a U.S. Bird Reservation in the Pacific were introduced to a group of small islands 300 miles away and in at most 17 years, like Darwin's finches, they had diversified their beaks, related muscles, and behavior to fill various ecological niches. Hear about this also at rsr.org/spetner. * Opals Can Form in "A Few Months" And Don't Need 100,000 Years: A leading authority on opals, Allan W. Eckert, observed that, "scientific papers and textbooks have told that the process of opal formation requires tens of thousands of years, perhaps hundreds of thousands... Not true." A 2011 peer-reviewed paper in a geology journal from Australia, where almost all the world's opal is found, reported on the: "new timetable for opal formation involving weeks to a few months and not the hundreds of thousands of years envisaged by the conventional weathering model." (And apparently, per a 2019 report from Entomology Today, opals can even form around insects!) More knowledgeable scientists resist the uncritical, group-think insistence on false super-slow formation rates (as also for manganese nodules, gold veins, stone, petroleum, canyons and gullies, and even guts, all below). Regarding opals, Darwinian bias led geologists to long ignore possible quick action, as from microbes, as a possible explanation for these mineraloids. For both in nature and in the lab, opals form rapidly, not even in 10,000 years, but in weeks. See this also from creationists by a geologist, a paleobiochemist, and a nuclear chemist. * Finches Speciate in Two Generations vs Two Million Years for Darwin's Birds?  Darwin's finches on the Galapagos Islands are said to have diversified into 14 species over a period of two million years. But in 2017 the journal Science reported a newcomer to the Island which within two generations spawned a reproductively isolated new species. In another instance as documented by Lee Spetner, a hundred birds of the same finch species introduced to an island cluster a 1,000 kilometers from Galapagos diversified into species with the typical variations in beak sizes, etc. "If this diversification occurred in less than seventeen years," Dr. Spetner asks, "why did Darwin's Galapagos finches [as claimed by evolutionists] have to take two million years?" * Blue Eyes Originated Not So Long Ago: Not a million years ago, nor a hundred thousand years ago, but based on a peer-reviewed paper in Human Genetics, a press release at Science Daily reports that, "research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today." * Adding the Entire Universe to our List of Not So Old Things? Based on March 2019 findings from Hubble, Nobel laureate Adam Riess of the Space Telescope Science Institute and his co-authors in the Astrophysical Journal estimate that the universe is about a billion years younger than previously thought! Then in September 2019 in the journal Science, the age dropped precipitiously to as low as 11.4 billion years! Of course, these measurements also further squeeze the canonical story of the big bang chronology with its many already existing problems including the insufficient time to "evolve" distant mature galaxies, galaxy clusters, superclusters, enormous black holes, filaments, bubbles, walls, and other superstructures. So, even though the latest estimates are still absurdly too old (Google: big bang predictions, and click on the #1 ranked article, or just go on over there to rsr.org/bb), regardless, we thought we'd plop the whole universe down on our List of Not So Old Things!   * After the Soft Tissue Discoveries, NOW Dino DNA: When a North Carolina State University paleontologist took the Tyrannosaurus Rex photos to the right of original biological material, that led to the 2016 discovery of dinosaur DNA, So far researchers have also recovered dinosaur blood vessels, collagen, osteocytes, hemoglobin, red blood cells, and various proteins. As of May 2018, twenty-six scientific journals, including Nature, Science, PNAS, PLoS One, Bone, and Journal of Vertebrate Paleontology, have confirmed the discovery of biomaterial fossils from many dinosaurs! Organisms including T. Rex, hadrosaur, titanosaur, triceratops, Lufengosaur, mosasaur, and Archaeopteryx, and many others dated, allegedly, even hundreds of millions of years old, have yielded their endogenous, still-soft biological material. See the web's most complete listing of 100+ journal papers (screenshot, left) announcing these discoveries at bflist.rsr.org and see it in layman's terms at rsr.org/soft. * Rapid Stalactites, Stalagmites, Etc.: A construction worker in 1954 left a lemonade bottle in one of Australia's famous Jenolan Caves. By 2011 it had been naturally transformed into a stalagmite (below, right). Increasing scientific knowledge is arguing for rapid cave formation (see below, Nat'l Park Service shrinks Carlsbad Caverns formation estimates from 260M years, to 10M, to 2M, to it "depends"). Likewise, examples are growing of rapid formations with typical chemical make-up (see bottle, left) of classic stalactites and stalagmites including:- in Nat'l Geo the Carlsbad Caverns stalagmite that rapidly covered a bat - the tunnel stalagmites at Tennessee's Raccoon Mountain - hundreds of stalactites beneath the Lincoln Memorial - those near Gladfelter Hall at Philadelphia's Temple University (send photos to Bob@rsr.org) - hundreds of stalactites at Australia's zinc mine at Mt. Isa.   - and those beneath Melbourne's Shrine of Remembrance. * Most Human Mutations Arose in 200 Generations: From Adam until Real Science Radio, in only 200 generations! The journal Nature reports The Recent Origin of Most Human Protein-coding Variants. As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts.- The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies evolving too quickly, galaxy clusters, and even human feet (which, like Mummy DNA, challenge the Out of Africa paradigm), jellyfish have gotten into the act squeezing evolution's timeline, here by 200 million years when they were found in strata allegedly a half-a-billion years old. Other examples, ironically referred to as Medusoid Problematica, are even found in pre-Cambrian strata. - 171 tadpoles of the same species buried in diatoms. - Leaves buried vertically through single-celled diatoms powerfully refute the claimed super-slow deposition of diatomaceous rock. - Many fossils, including a Mesosaur, have been buried in multiple "varve" layers, which are claimed to be annual depositions, yet they show no erosional patterns that would indicate gradual burial (as they claim, absurdly, over even thousands of years). - A single whale skeleton preserved in California in dozens of layers of diatom deposits thus forming a polystrate fossil. - 40 whales buried in the desert in Chile. "What's really interesting is that this didn't just happen once," said Smithsonian evolutionist Dr. Nick Pyenson. It happened four times." Why's that? Because "the fossil site has at least four layers", to which Real Science Radio's Bob Enyart replies: "Ha ha ha ha ha ha ha ha ha ha ha", with RSR co-host Fred Williams thoughtfully adding, "Ha ha!" * Polystrate Trees: Examples abound around the world of polystrate trees:  - Yellowstone's petrified polystrate forest (with the NPS exhibit sign removed; see below) with successive layers of rootless trees demonstrating the rapid deposition of fifty layers of strata. - A similarly formed polystrate fossil forest in France demonstrating the rapid deposition of a dozen strata. - In a thousand locations including famously the Fossil Cliffs of Joggins, Nova Scotia, polystrate fossils such as trees span many strata. - These trees lack erosion: Not only should such fossils, generally speaking, not even exist, but polystrates including trees typically show no evidence of erosion increasing with height. All of this powerfully disproves the claim that the layers were deposited slowly over thousands or millions of years. In the experience of your RSR radio hosts, evolutionists commonly respond to this hard evidence with mocking. See CRSQ June 2006, ICR Impact #316, and RSR 8-11-06 at KGOV.com. * Yellowstone Petrified Trees Sign Removed: The National Park Service removed their incorrect sign (see left and more). The NPS had claimed that in dozens of different strata over a 40-square mile area, many petrified trees were still standing where they had grown. The NPS eventually removed the sign partly because those petrified trees had no root systems, which they would have had if they had grown there. Instead, the trees of this "fossil forest" have roots that are abruptly broken off two or three feet from their trunks. If these mature trees actually had been remnants of sequential forests that had grown up in strata layer on top of strata layer, 27 times on Specimen Ridge (and 50 times at Specimen Creek), such a natural history implies passage of more time than permitted by biblical chronology. So, don't trust the National Park Service on historical science because they're wrong on the age of the Earth. * Wood Petrifies Quickly: Not surprisingly, by the common evolutionary knee-jerk claim of deep time, "several researchers believe that several millions of years are necessary for the complete formation of silicified wood". Our List of Not So Old and Not So Slow Things includes the work of five Japanese scientists who proved creationist research and published their results in the peer-reviewed journal Sedimentary Geology showing that wood can and does petrify rapidly. Modern wood significantly petrified in 36 years these researchers concluded that wood buried in strata could have been petrified in "a fairly short period of time, in the order of several tens to hundreds of years." * The Scablands: The primary surface features of the Scablands, which cover thousands of square miles of eastern Washington, were long believed to have formed gradually. Yet, against the determined claims of uniformitarian geologists, there is now overwhelming evidence as presented even in a NOVA TV program that the primary features of the Scablands formed rapidly from a catastrophic breach of Lake Missoula causing a massive regional flood. Of course evolutionary geologists still argue that the landscape was formed over tens of thousands of years, now by claiming there must have been a hundred Missoula floods. However, the evidence that there was Only One Lake Missoula Flood has been powerfully reinforced by a University of Colorado Ph.D. thesis. So the Scablands itself is no longer available to old-earthers as de facto evidence for the passage of millions of years. * The Heart Mountain Detachment: in Wyoming just east of Yellowstone, this mountain did not break apart slowly by uniformitarian processes but in only about half-an-hour as widely reported including in the evolutionist LiveScience.com, "Land Speed Record: Mountain Moves 62 Miles in 30 Minutes." The evidence indicates that this mountain of rock covering 425 square miles rapidly broke into 50 pieces and slid apart over an area of more than 1,300 square miles in a biblical, not a "geological," timeframe.  * "150 Million" year-old Squid Ink Not Decomposed: This still-writable ink had dehydrated but had not decomposed! The British Geological Survey's Dr. Phil Wilby, who excavated the fossil, said, "It is difficult to imagine how you can have something as soft and sloppy as an ink sac fossilised in three dimensions, still black, and inside a rock that is 150 million years old." And the Daily Mail states that, "the black ink was of exactly the same structure as that of today's version", just desiccated. And Wilby added, "Normally you would find only the hard parts like the shell and bones fossilised but... these creatures... can be dissected as if they are living animals, you can see the muscle fibres and cells. It is difficult to imagine... The structure is similar to ink from a modern squid so we can write with it..." Why is this difficult for evolutionists to imagine? Because as Dr. Carl Wieland writes, "Chemical structures 'fall apart' all by themselves over time due to the randomizing effects of molecular motion." Decades ago Bob Enyart broadcast a geology program about Mount St. Helens' catastrophic destruction of forests and the hydraulic transportation and upright deposition of trees. Later, Bob met the chief ranger from Haleakala National Park on Hawaii's island of Maui, Mark Tanaka-Sanders. The ranger agreed to correspond with his colleague at Yellowstone to urge him to have the sign removed. Thankfully, it was then removed. (See also AIG, CMI, and all the original Yellowstone exhibit photos.) Groundbreaking research conducted by creation geologist Dr. Steve Austin in Spirit Lake after Mount St. Helens eruption provided a modern-day analog to the formation of Yellowstone fossil forest. A steam blast from that volcano blew over tens of thousands of trees leaving them without attached roots. Many thousands of those trees were floating upright in Spirit Lake, and began sinking at varying rates into rapidly and sporadically deposited sediments. Once Yellowstone's successive forest interpretation was falsified (though like with junk DNA, it's too big to fail, so many atheists and others still cling to it), the erroneous sign was removed. * Asiatic vs. European Honeybees: These two populations of bees have been separated supposedly for seven million years. A researcher decided to put the two together to see what would happen. What we should have here is a failure to communicate that would have resulted after their "language" evolved over millions of years. However, European and Asiatic honeybees are still able to communicate, putting into doubt the evolutionary claim that they were separated over "geologic periods." For more, see the Public Library of Science, Asiatic Honeybees Can Understand Dance Language of European Honeybees. (Oh yeah, and why don't fossils of poorly-formed honeycombs exist, from the millions of years before the bees and natural selection finally got the design right? Ha! Because they don't exist! :) Nautiloid proves rapid limestone formation. * Remember the Nautiloids: In the Grand Canyon there is a limestone layer averaging seven feet thick that runs the 277 miles of the canyon (and beyond) that covers hundreds of square miles and contains an average of one nautiloid fossil per square meter. Along with many other dead creatures in this one particular layer, 15% of these nautiloids were killed and then fossilized standing on their heads. Yes, vertically. They were caught in such an intense and rapid catastrophic flow that gravity was not able to cause all of their dead carcasses to fall over on their sides. Famed Mount St. Helens geologist Steve Austin is also the world's leading expert on nautiloid fossils and has worked in the canyon and presented his findings to the park's rangers at the invitation of National Park Service officials. Austin points out, as is true of many of the world's mass fossil graveyards, that this enormous nautiloid deposition provides indisputable proof of the extremely rapid formation of a significant layer of limestone near the bottom of the canyon, a layer like the others we've been told about, that allegedly formed at the bottom of a calm and placid sea with slow and gradual sedimentation. But a million nautiloids, standing on their heads, literally, would beg to differ. At our sister stie, RSR provides the relevant Geologic Society of America abstract, links, and video. *  Now It's Allegedly Two Million Year-Old Leaves: "When we started pulling leaves out of the soil, that was surreal, to know that it's millions of years old..." sur-re-al: adjective: a bizarre mix of fact and fantasy. In this case, the leaves are the facts. Earth scientists from Ohio State and the University of Minnesota say that wood and leaves they found in the Canadian Arctic are at least two million years old, and perhaps more than ten million years old, even though the leaves are just dry and crumbly and the wood still burns! * Gold Precipitates in Veins in Less than a Second: After geologists submitted for decades to the assumption that each layer of gold would deposit at the alleged super slow rates of geologic process, the journal Nature Geoscience reports that each layer of deposition can occur within a few tenths of a second. Meanwhile, at the Lihir gold deposit in Papua New Guinea, evolutionists assumed the more than 20 million ounces of gold in the Lihir reserve took millions of years to deposit, but as reported in the journal Science, geologists can now demonstrate that the deposit could have formed in thousands of years, or far more quickly! Iceland's not-so-old Surtsey Island looks ancient. * Surtsey Island, Iceland: Of the volcanic island that formed in 1963, New Scientist reported in 2007 about Surtsey that "geographers... marvel that canyons, gullies and other land features that typically take tens of thousands or millions of years to form were created in less than a decade." Yes. And Sigurdur Thorarinsson, Iceland's chief  geologist, wrote in the months after Surtsey formed, "that the time scale," he had been trained "to attach to geological developments is misleading." [For what is said to] take thousands of years... the same development may take a few weeks or even days here [including to form] a landscape... so varied and mature that it was almost beyond belief... wide sandy beaches and precipitous crags... gravel banks and lagoons, impressive cliffs… hollows, glens and soft undulating land... fractures and faultscarps, channels and screes… confounded by what met your eye... boulders worn by the surf, some of which were almost round... -Iceland's chief geologist * The Palouse River Gorge: In the southeast of Washington State, the Palouse River Gorge is one of many features formed rapidly by 500 cubic miles of water catastrophically released with the breaching of a natural dam in the Lake Missoula Flood (which gouged out the Scablands as described above). So, hard rock can be breached and eroded rapidly. * Leaf Shapes Identical for 190 Million Years?  From Berkley.edu, "Ginkgo biloba... dates back to... about 190 million years ago... fossilized leaf material from the Tertiary species Ginkgo adiantoides is considered similar or even identical to that produced by modern Ginkgo biloba trees... virtually indistinguishable..." The literature describes leaf shapes as "spectacularly diverse" sometimes within a species but especially across the plant kingdom. Because all kinds of plants survive with all kinds of different leaf shapes, the conservation of a species retaining a single shape over alleged deep time is a telling issue. Darwin's theory is undermined by the unchanging shape over millions of years of a species' leaf shape. This lack of change, stasis in what should be an easily morphable plant trait, supports the broader conclusion that chimp-like creatures did not become human beings and all the other ambitious evolutionary creation of new kinds are simply imagined. (Ginkgo adiantoides and biloba are actually the same species. Wikipedia states, "It is doubtful whether the Northern Hemisphere fossil species of Ginkgo can be reliably distinguished." For oftentimes, as documented by Dr. Carl Werner in his Evolution: The Grand Experiment series, paleontogists falsely speciate identical specimens, giving different species names, even different genus names, to the fossil and living animals that appear identical.) * Box Canyon, Idaho: Geologists now think Box Canyon in Idaho, USA, was carved by a catastrophic flood and not slowly over millions of years with 1) huge plunge pools formed by waterfalls; 2) the almost complete removal of large basalt boulders from the canyon; 3) an eroded notch on the plateau at the top of the canyon; and 4) water scour marks on the basalt plateau leading to the canyon. Scientists calculate that the flood was so large that it could have eroded the whole canyon in as little as 35 days. See the journal Science, Formation of Box Canyon, Idaho, by Megaflood, and the Journal of Creation, and Creation Magazine. * Manganese Nodules Rapid Formation: Allegedly, as claimed at the Wikipedia entry from 2005 through 2021: "Nodule growth is one of the slowest of all geological phenomena – in the order of a centimeter over several million years." Wow, that would be slow! And a Texas A&M Marine Sciences technical slide presentation says, “They grow very slowly (mm/million years) and can be tens of millions of years old.” But according to a World Almanac documentary they have formed "around beer cans," said marine geologist Dr. John Yates in the 1997 video Universe Beneath the Sea: The Next Frontier. There are also reports of manganese nodules forming around ships sunk in the First World War. See more at at youngearth.com, at TOL, in the print edition of the Journal of Creation, and in this typical forum discussion with atheists (at the Chicago Cubs forum no less :). * "6,000 year-old" Mitochondrial Eve: As the Bible calls "Eve... the mother of all living" (Gen. 3:20), genetic researchers have named the one woman from whom all humans have descended "Mitochondrial Eve." But in a scientific attempt to date her existence, they openly admit that they included chimpanzee DNA in their analysis in order to get what they viewed as a reasonably old date of 200,000 years ago (which is still surprisingly recent from their perspective, but old enough not to strain Darwinian theory too much). But then as widely reported including by Science magazine, when they dropped the chimp data and used only actual human mutation rates, that process determined that Eve lived only six thousand years ago! In Ann Gibbon's Science article, "Calibrating the Mitochondrial Clock," rather than again using circular reasoning by assuming their conclusion (that humans evolved from ape-like creatures), they performed their calculations using actual measured mutation rates. This peer-reviewed journal then reported that if these rates have been constant, "mitochondrial Eve… would be a mere 6000 years old." See also the journal Nature and creation.com's "A shrinking date for Eve," and Walt Brown's assessment. Expectedly though, evolutionists have found a way to reject their own unbiased finding (the conclusion contrary to their self-interest) by returning to their original method of using circular reasoning, as reported in the American Journal of Human Genetics, "calibrating against recent evidence for the divergence time of humans and chimpanzees,"  to reset their mitochondrial clock back to 200,000 years. * Even Younger Y-Chromosomal Adam: (Although he should be called, "Y-Chromosomal Noah.") While we inherit our mtDNA only from our mothers, only men have a Y chromosome (which incidentally genetically disproves the cla

As summarized by geneticist co-author Joshua Akey, "Most of the mutations that we found arose in the last 200 generations or so" (the same number previously published by biblical creationists). Another 2012 paper, in the American Journal of Physical Anthropology (Eugenie Scott's own field) on High mitochondrial mutation rates, shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out, indicates that mtEve would have lived about 200 generations ago. That's not so old! * National Geographic's Not-So-Old Hard-Rock Canyon at Mount St. Helens: As our List of Not So Old Things (this web page) reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years (or at least just long enough to contradict Moses' chronology in Genesis.) However, with closer study, routinely, more and more old ages get revised downward to fit the world's growing scientific knowledge. So the trend is not that more information lengthens ages, but rather, as data replaces guesswork, ages tend to shrink until they are consistent with the young-earth biblical timeframe. Consistent with this observation, the May 2000 issue of National Geographic quotes the U.S. Forest Service's scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. "You'd expect a hard-rock canyon to be thousands, even hundreds of thousands of years old. But this was cut in less than a decade." And as for the volcano itself, while again, the kneejerk reaction of old-earthers would be to claim that most geologic features are hundreds of thousands or millions of years old, the atheistic National Geographic magazine acknowledges from the evidence that Mount St. Helens, the volcanic mount, is only about 4,000 years old! See below and more at rsr.org/mount-st-helens. * Mount St. Helens Dome Ten Years Old not 1.7 Million: Geochron Laboratories of Cambridge, Mass., using potassium-argon and other radiometric techniques claims the rock sample they dated, from the volcano's dome, solidified somewhere between 340,000 and 2.8 million years ago. However photographic evidence and historical reports document the dome's formation during the 1980s, just ten years prior to the samples being collected. With the age of this rock known, radiometric dating therefore gets the age 99.99999% wrong. * Devils Hole Pupfish Isolated Not for 13,000 Years But for 100: Secular scientists default to knee-jerk, older-than-Bible-age dates. However, a tiny Mojave desert fish is having none of it. Rather than having been genetically isolated from other fish for 13,000 years (which would make this small school of fish older than the Earth itself), according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about 100 years, give or take a few. * Polystrates like Spines and Rare Schools of Fossilized Jellyfish: Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form. And because jellyfish have no skeleton, as Charles Darwin pointed out, it is rare to find them among fossils. But now, reported in the journal Geology, a school of jellyfish fossils have been found throughout those same seven layers. So, polystrate fossils that condense the time of strata deposition from eons to hours or months, include: - Jellyfish in central Wisconsin were not deposited and fossilized over a million years but during a single event quick enough to trap a whole school. (This fossil school, therefore, taken as a unit forms a polystrate fossil.) Examples are everywhere that falsify the claims of strata deposition over millions of years. - Countless trilobites buried in astounding three dimensionality around the world are meticulously recovered from limestone, much of which is claimed to have been deposited very slowly. Contrariwise, because these specimens were buried rapidly in quickly laid down sediments, they show no evidence of greater erosion on their upper parts as compared to their lower parts.- The delicacy of radiating spine polystrates, like tadpole and jellyfish fossils, especially clearly demonstrate the rapidity of such strata deposition. - A second school of jellyfish, even though they rarely fossilized, exists in another locale with jellyfish fossils in multiple layers, in Australia's Brockman Iron Formation, constraining there too the rate of strata deposition. By the way, jellyfish are an example of evolution's big squeeze. Like galaxies evolving too quickly, galaxy clusters, and even human feet (which, like Mummy DNA, challenge the Out of Africa paradigm), jellyfish have gotten into the act squeezing evolution's timeline, here by 200 million years when they were found in strata allegedly a half-a-billion years old. Other examples, ironically referred to as Medusoid Problematica, are even found in pre-Cambrian strata. - 171 tadpoles of the same species buried in diatoms. - Leaves buried vertically through single-celled diatoms powerfully refute the claimed super-slow deposition of diatomaceous rock. - Many fossils, including a Mesosaur, have been buried in multiple "varve" layers, which are claimed to be annual depositions, yet they show no erosional patterns that would indicate gradual burial (as they claim, absurdly, over even thousands of years). - A single whale skeleton preserved in California in dozens of layers of diatom deposits thus forming a polystrate fossil. - 40 whales buried in the desert in Chile. "What's really interesting is that this didn't just happen once," said Smithsonian evolutionist Dr. Nick Pyenson. It happened four times." Why's that? Because "the fossil site has at least four layers", to which Real Science Radio's Bob Enyart replies: "Ha ha ha ha ha ha ha ha ha ha ha", with RSR co-host Fred Williams thoughtfully adding, "Ha ha!" * Polystrate Trees: Examples abound around the world of polystrate trees:  - Yellowstone's petrified polystrate forest (with the NPS exhibit sign removed; see below) with successive layers of rootless trees demonstrating the rapid deposition of fifty layers of strata. - A similarly formed polystrate fossil forest in France demonstrating the rapid deposition of a dozen strata. - In a thousand locations including famously the Fossil Cliffs of Joggins, Nova Scotia, polystrate fossils such as trees span many strata. - These trees lack erosion: Not only should such fossils, generally speaking, not even exist, but polystrates including trees typically show no evidence of erosion increasing with height. All of this powerfully disproves the claim that the layers were deposited slowly over thousands or millions of years. In the experience of your RSR radio hosts, evolutionists commonly respond to this hard evidence with mocking. See CRSQ June 2006, ICR Impact #316, and RSR 8-11-06 at KGOV.com. * Yellowstone Petrified Trees Sign Removed: The National Park Service removed their incorrect sign (see left and more). The NPS had claimed that in dozens of different strata over a 40-square mile area, many petrified trees were still standing where they had grown. The NPS eventually removed the sign partly because those petrified trees had no root systems, which they would have had if they had grown there. Instead, the trees of this "fossil forest" have roots that are abruptly broken off two or three feet from their trunks. If these mature trees actually had been remnants of sequential forests that had grown up in strata layer on top of strata layer, 27 times on Specimen Ridge (and 50 times at Specimen Creek), such a natural history implies passage of more time than permitted by biblical chronology. So, don't trust the National Park Service on historical science because they're wrong on the age of the Earth. * Wood Petrifies Quickly: Not surprisingly, by the common evolutionary knee-jerk claim of deep time, "several researchers believe that several millions of years are necessary for the complete formation of silicified wood". Our List of Not So Old and Not So Slow Things includes the work of five Japanese scientists who proved creationist research and published their results in the peer-reviewed journal Sedimentary Geology showing that wood can and does petrify rapidly. Modern wood significantly petrified in 36 years these researchers concluded that wood buried in strata could have been petrified in "a fairly short period of time, in the order of several tens to hundreds of years." * The Scablands: The primary surface features of the Scablands, which cover thousands of square miles of eastern Washington, were long believed to have formed gradually. Yet, against the determined claims of uniformitarian geologists, there is now overwhelming evidence as presented even in a NOVA TV program that the primary features of the Scablands formed rapidly from a catastrophic breach of Lake Missoula causing a massive regional flood. Of course evolutionary geologists still argue that the landscape was formed over tens of thousands of years, now by claiming there must have been a hundred Missoula floods. However, the evidence that there was Only One Lake Missoula Flood has been powerfully reinforced by a University of Colorado Ph.D. thesis. So the Scablands itself is no longer available to old-earthers as de facto evidence for the passage of millions of years. * The Heart Mountain Detachment: in Wyoming just east of Yellowstone, this mountain did not break apart slowly by uniformitarian processes but in only about half-an-hour as widely reported including in the evolutionist LiveScience.com, "Land Speed Record: Mountain Moves 62 Miles in 30 Minutes." The evidence indicates that this mountain of rock covering 425 square miles rapidly broke into 50 pieces and slid apart over an area of more than 1,300 square miles in a biblical, not a "geological," timeframe.  * "150 Million" year-old Squid Ink Not Decomposed: This still-writable ink had dehydrated but had not decomposed! The British Geological Survey's Dr. Phil Wilby, who excavated the fossil, said, "It is difficult to imagine how you can have something as soft and sloppy as an ink sac fossilised in three dimensions, still black, and inside a rock that is 150 million years old." And the Daily Mail states that, "the black ink was of exactly the same structure as that of today's version", just desiccated. And Wilby added, "Normally you would find only the hard parts like the shell and bones fossilised but... these creatures... can be dissected as if they are living animals, you can see the muscle fibres and cells. It is difficult to imagine... The structure is similar to ink from a modern squid so we can write with it..." Why is this difficult for evolutionists to imagine? Because as Dr. Carl Wieland writes, "Chemical structures 'fall apart' all by themselves over time due to the randomizing effects of molecular motion." Decades ago Bob Enyart broadcast a geology program about Mount St. Helens' catastrophic destruction of forests and the hydraulic transportation and upright deposition of trees. Later, Bob met the chief ranger from Haleakala National Park on Hawaii's island of Maui, Mark Tanaka-Sanders. The ranger agreed to correspond with his colleague at Yellowstone to urge him to have the sign removed. Thankfully, it was then removed. (See also AIG, CMI, and all the original Yellowstone exhibit photos.) Groundbreaking research conducted by creation geologist Dr. Steve Austin in Spirit Lake after Mount St. Helens eruption provided a modern-day analog to the formation of Yellowstone fossil forest. A steam blast from that volcano blew over tens of thousands of trees leaving them without attached roots. Many thousands of those trees were floating upright in Spirit Lake, and began sinking at varying rates into rapidly and sporadically deposited sediments. Once Yellowstone's successive forest interpretation was falsified (though like with junk DNA, it's too big to fail, so many atheists and others still cling to it), the erroneous sign was removed. * Asiatic vs. European Honeybees: These two populations of bees have been separated supposedly for seven million years. A researcher decided to put the two together to see what would happen. What we should have here is a failure to communicate that would have resulted after their "language" evolved over millions of years. However, European and Asiatic honeybees are still able to communicate, putting into doubt the evolutionary claim that they were separated over "geologic periods." For more, see the Public Library of Science, Asiatic Honeybees Can Understand Dance Language of European Honeybees. (Oh yeah, and why don't fossils of poorly-formed honeycombs exist, from the millions of years before the bees and natural selection finally got the design right? Ha! Because they don't exist! :) Nautiloid proves rapid limestone formation.* Remember the Nautiloids: In the Grand Canyon there is a limestone layer averaging seven feet thick that runs the 277 miles of the canyon (and beyond) that covers hundreds of square miles and contains an average of one nautiloid fossil per square meter. Along with many other dead creatures in this one particular layer, 15% of these nautiloids were killed and then fossilized standing on their heads. Yes, vertically. They were caught in such an intense and rapid catastrophic flow that gravity was not able to cause all of their dead carcasses to fall over on their sides. Famed Mount St. Helens geologist Steve Austin is also the world's leading expert on nautiloid fossils and has worked in the canyon and presented his findings to the park's rangers at the invitation of National Park Service officials. Austin points out, as is true of many of the world's mass fossil graveyards, that this enormous nautiloid deposition provides indisputable proof of the extremely rapid formation of a significant layer of limestone near the bottom of the canyon, a layer like the others we've been told about, that allegedly formed at the bottom of a calm and placid sea with slow and gradual sedimentation. But a million nautiloids, standing on their heads, literally, would beg to differ. At our sister stie, RSR provides the relevant Geologic Society of America abstract, links, and video. *  Now It's Allegedly Two Million Year-Old Leaves: "When we started pulling leaves out of the soil, that was surreal, to know that it's millions of years old..." sur-re-al: adjective: a bizarre mix of fact and fantasy. In this case, the leaves are the facts. Earth scientists from Ohio State and the University of Minnesota say that wood and leaves they found in the Canadian Arctic are at least two million years old, and perhaps more than ten million years old, even though the leaves are just dry and crumbly and the wood still burns! * Gold Precipitates in Veins in Less than a Second: After geologists submitted for decades to the assumption that each layer of gold would deposit at the alleged super slow rates of geologic process, the journal Nature Geoscience reports that each layer of deposition can occur within a few tenths of a second. Meanwhile, at the Lihir gold deposit in Papua New Guinea, evolutionists assumed the more than 20 million ounces of gold in the Lihir reserve took millions of years to deposit, but as reported in the journal Science, geologists can now demonstrate that the deposit could have formed in thousands of years, or far more quickly! Iceland's not-so-old Surtsey Island looks ancient.* Surtsey Island, Iceland: Of the volcanic island that formed in 1963, New Scientist reported in 2007 about Surtsey that "geographers... marvel that canyons, gullies and other land features that typically take tens of thousands or millions of years to form were created in less than a decade." Yes. And Sigurdur Thorarinsson, Iceland's chief  geologist, wrote in the months after Surtsey formed, "that the time scale," he had been trained "to attach to geological developments is misleading." [For what is said to] take thousands of years... the same development may take a few weeks or even days here [including to form] a landscape... so varied and mature that it was almost beyond belief... wide sandy beaches and precipitous crags... gravel banks and lagoons, impressive cliffs… hollows, glens and soft undulating land... fractures and faultscarps, channels and screes… confounded by what met your eye... boulders worn by the surf, some of which were almost round... -Iceland's chief geologist * The Palouse River Gorge: In the southeast of Washington State, the Palouse River Gorge is one of many features formed rapidly by 500 cubic miles of water catastrophically released with the breaching of a natural dam in the Lake Missoula Flood (which gouged out the Scablands as described above). So, hard rock can be breached and eroded rapidly. * Leaf Shapes Identical for 190 Million Years?  From Berkley.edu, "Ginkgo biloba... dates back to... about 190 million years ago... fossilized leaf material from the Tertiary species Ginkgo adiantoides is considered similar or even identical to that produced by modern Ginkgo biloba trees... virtually indistinguishable..." The literature describes leaf shapes as "spectacularly diverse" sometimes within a species but especially across the plant kingdom. Because all kinds of plants survive with all kinds of different leaf shapes, the conservation of a species retaining a single shape over alleged deep time is a telling issue. Darwin's theory is undermined by the unchanging shape over millions of years of a species' leaf shape. This lack of change, stasis in what should be an easily morphable plant trait, supports the broader conclusion that chimp-like creatures did not become human beings and all the other ambitious evolutionary creation of new kinds are simply imagined. (Ginkgo adiantoides and biloba are actually the same species. Wikipedia states, "It is doubtful whether the Northern Hemisphere fossil species of Ginkgo can be reliably distinguished." For oftentimes, as documented by Dr. Carl Werner in his Evolution: The Grand Experiment series, paleontogists falsely speciate identical specimens, giving different species names, even different genus names, to the fossil and living animals that appear identical.) * Box Canyon, Idaho: Geologists now think Box Canyon in Idaho, USA, was carved by a catastrophic flood and not slowly over millions of years with 1) huge plunge pools formed by waterfalls; 2) the almost complete removal of large basalt boulders from the canyon; 3) an eroded notch on the plateau at the top of the canyon; and 4) water scour marks on the basalt plateau leading to the canyon. Scientists calculate that the flood was so large that it could have eroded the whole canyon in as little as 35 days. See the journal Science, Formation of Box Canyon, Idaho, by Megaflood, and the Journal of Creation, and Creation Magazine. * Manganese Nodules Rapid Formation: Allegedly, as claimed at the Wikipedia entry from 2005 through 2021: "Nodule growth is one of the slowest of all geological phenomena – in the order of a centimeter over several million years." Wow, that would be slow! And a Texas A&M Marine Sciences technical slide presentation says, “They grow very slowly (mm/million years) and can be tens of millions of years old.” But according to a World Almanac documentary they have formed "around beer cans," said marine geologist Dr. John Yates in the 1997 video Universe Beneath the Sea: The Next Frontier. There are also reports of manganese nodules forming around ships sunk in the First World War. See more at at youngearth.com, at TOL, in the print edition of the Journal of Creation, and in this typical forum discussion with atheists (at the Chicago Cubs forum no less :). * "6,000 year-old" Mitochondrial Eve: As the Bible calls "Eve... the mother of all living" (Gen. 3:20), genetic researchers have named the one woman from whom all humans have descended "Mitochondrial Eve." But in a scientific attempt to date her existence, they openly admit that they included chimpanzee DNA in their analysis in order to get what they viewed as a reasonably old date of 200,000 years ago (which is still surprisingly recent from their perspective, but old enough not to strain Darwinian theory too much). But then as widely reported including by Science magazine, when they dropped the chimp data and used only actual human mutation rates, that process determined that Eve lived only six thousand years ago! In Ann Gibbon's Science article, "Calibrating the Mitochondrial Clock," rather than again using circular reasoning by assuming their conclusion (that humans evolved from ape-like creatures), they performed their calculations using actual measured mutation rates. This peer-reviewed journal then reported that if these rates have been constant, "mitochondrial Eve… would be a mere 6000 years old." See also the journal Nature and creation.com's "A shrinking date for Eve," and Walt Brown's assessment. Expectedly though, evolutionists have found a way to reject their own unbiased finding (the conclusion contrary to their self-interest) by returning to their original method of using circular reasoning, as reported in the American Journal of Human Genetics, "calibrating against recent evidence for the divergence time of humans and chimpanzees,"  to reset their mitochondrial clock back to 200,000 years. * Even Younger Y-Chromosomal Adam: (Although he should be called, "Y-Chromosomal Noah.") While we inherit our mtDNA only from our mothers, only men have a Y chromosome (which incidentally genetically disproves the claim that the fetus is "part of the woman's body," since the little boy's y chromosome could never be part of mom's body). Based on documented mutation rates on and the extraordinary lack o

The upper Oligocene Sooke Formation that outcrops on southwestern Vancouver Island, British Columbia is a wonderful place to collect and especially good for families. As well as amazing west coast scenery, the beach site outcrop has a lovely soft matrix with well-preserved fossil molluscs, often with the shell material preserved (Clark and Arnold, 1923). While the site has been known since the 1890s, my first trip here was in the early 1990s as part of a Vancouver Paleontological Society (VanPS) fossil field trip. By the Oligocene ocean temperatures had cooled to near modern levels and the taxa preserved here as fossils bear a strong resemblance to those found living beneath the Strait of Juan de Fuca today. Gastropods, bivalves, echinoids, coral, chitin and limpets are common-ish — and on rare occasions, fossil marine mammals, cetacean and bird bones are discovered. Back in 2015, a family found the fossilized bones from a 25-million-year-old wing-propelled flightless diving bird while out strolling the shoreline near Sooke. Not knowing what they'd found but recognizing it as significant, the bones were brought to the Royal British Columbia Museum to identify. The bones found their way into the hands of Gary Kaiser. Kaiser worked as a biologist for Environment Canada and the Nature Conservatory of Canada. After retirement, he turned his eye from our extant avian friends to their fossil lineage. The thing about passion is it never retires. Gary is now a research associate with the Royal British Columbia Museum, published author and continues his research on birds and their paleontological past. Kaiser identified the well-preserved coracoid bones as the first example from Canada of a Plotopteridae, an extinct family that lived in the North Pacific from the late Eocene to the early Miocene. In honour of our First Nations communities who settled the Sooke area, Kaiser named the new genus and species Stemec suntokum. Avian fossils from the Sooke Formation are rare. We are especially lucky that the bird bone was fossilized at all. These are delicate bones and tasty. Scavengers often get to them well before they have a chance and the right conditions to fossilize. Doubly lucky is that the find was of a coracoid, a bone from the shoulder that provides information on how this bird moved and dove through the water similar to a penguin. It's the wee bit that flexes as the bird moves his wing up and down. Picture a penguin doing a little waddle and flapping their flipper-like wings getting ready to hop near and dive into the water. Now imagine them expertly porpoising — gracefully jumping out of the sea and zigzagging through the ocean to avoid predators. It is likely that the Sooke find did some if not all of these activities.

The gang discuss two papers that describe unique animal fossils which have been known but haven’t (until now) been formally described. The first is “Collins Monster”, a lobopod from the Cambrian, and the second is a fossil dolphin which is similar to an orca. Meanwhile, James rehabilitates some dolphins, Amanda saw a thing, and Curt witnesses true beauty.   Up-Goer Five (Amanda Version):  Today our friends talk about a strange animal with cute legs and big parts that go to a point, and a really big animal that used to have hair that looks like an animal with no legs but actually does have legs. Both of these things have been known about for a long time, but no one gave them a name. They were used to figure out the family tree of animals, but never had a name. These papers give them a name, which is a very important thing. The strange animal with cute legs and big parts that go to a point is very close to other strange animals with cute legs that we have talked about before. The paper does put them in a different box than we are used to seeing, which we talk about a little and find maybe a little strange. The big animal that used to have hair and looks like an animal that has no legs but it actually has legs looks like it is close to one animal that had hair and looks like it has no legs, which shows that these things show up many times as time goes on. They also show some family trees, but only one is in the paper, the rest are in the other stuff on the space where people store all their stuff today.      References:  Caron, Jean‐Bernard, and Cédric Aria.

May 2020 Radio announcer: Time to talk Geopark once again. Joined by Geo educator Sasha Morriss. Sasha, still working from home at the moment. Geoeducator: That's right, yes, I'm still working remotely. Radio announcer: But you've been really active and busy, I guess. Geoeducator: Oh, yeah. Look, it's been a really good opportunity for us just to develop a lot more online resources. So we've got a kids page up and running, lots of activities in kid friendly language. And we've also set up a resources page specifically for teachers to use. Now, teachers, you know, not just in schools, teachers are parents, teachers are family members. So if you've got children that you care for or in your life, jump online and have a look. And there might be some resources there that the people in your family find interesting. Radio announcer: Now, one of the things you have been working on, I understand, is about timelines. Geoeducator: That's right. Yes. So geological timescales and timelines is what we've been working on lately. And that's available online now. So we've got some text around that explaining what is the geological time scale and also the time scale itself. And it has been drawn up in a column form. So just to run over it briefly, the geological time scale is massive. It's very difficult for us to get our minds around, you know, millions of years. So what we've done is we've re created one specifically for the Waitaki District that tells the story of Zealandia. So everything on this geological timescale to date relates back to things that we discuss in Kids Corner. So there's nothing in there that's going to throw you and think, oh, what's that? It's all things that you can cross reference to Kids corner. And it covers right from when New Zealand was part of Gondwana - basement rocks were being formed through to the separation of Zealandia. And then what we see recorded here in the Waitaki District with the marine transgression, the volcanism, we've got glaciation etc. So it's not a thing to really get hung up on the actual numbers, but it's the order of things. What happened first? What happened next etc. And it just put things into context for people. And I think makes things a little bit more accessible and clearer for people. So we'd just really appreciate people's feedback as to what they think. And I guess one thing to keep in mind when you're looking at the geological time scale is one of the assumptions that's made is that things happen at a constant rate over time. Now, we know in reality that this is not true, that you have catastrophic events that do create things that would be recorded in the geological time scale. However, over time, we kind of assume that these things even out. And so there's lots of factors that come into play when you read the geological time scale. So if you read the text, you'll see there is a margin of error that is built in there. But when you start talking about millions of years, you know, you can have significant margins of era. They can be, you know, a million years here or there. So that's why geologists tend to talk about epochs or periods of time. So when you hear Oligocene, Eocene, Miocene - they're periods of time that span millions and millions of years. And that's what geologists tend to talk about rather than specific dates. Radio announcer: And all of that is available on the Web site. Geoeducator: It's all available on the Web site. So jump on there and have a look. And we would just love to hear your feedback. Radio announcer: And that Web site address, again is... Geoeducator: The website address is www.whitestonegeopark.nz Radio announcer: Thanks for your time, Sasha. We'll catch up again next time.

The Mammalian Era on Urantia (693.1) 61:0.1 THE era of mammals extends from the times of the origin of placental mammals to the end of the ice age, covering a little less than fifty million years. (693.2) 61:0.2 During this Cenozoic age the world’s landscape presented an attractive appearance — rolling hills, broad valleys, wide rivers, and great forests. Twice during this sector of time the Panama Isthmus went up and down; three times the Bering Strait land bridge did the same. The animal types were both many and varied. The trees swarmed with birds, and the whole world was an animal paradise, notwithstanding the incessant struggle of the evolving animal species for supremacy.* (693.3) 61:0.3 The accumulated deposits of the five periods of this fifty-million-year era contain the fossil records of the successive mammalian dynasties and lead right up through the times of the actual appearance of man himself. 1. The New Continental Land Stage The Age of Early Mammals (693.4) 61:1.1 50,000,000 years ago the land areas of the world were very generally above water or only slightly submerged. The formations and deposits of this period are both land and marine, but chiefly land. For a considerable time the land gradually rose but was simultaneously washed down to the lower levels and toward the seas. (693.5) 61:1.2 Early in this period and in North America the placental type of mammals suddenly appeared, and they constituted the most important evolutionary development up to this time. Previous orders of nonplacental mammals had existed, but this new type sprang directly and suddenly from the pre-existent reptilian ancestor whose descendants had persisted on down through the times of dinosaur decline. The father of the placental mammals was a small, highly active, carnivorous, springing type of dinosaur. (693.6) 61:1.3 Basic mammalian instincts began to be manifested in these primitive mammalian types. Mammals possess an immense survival advantage over all other forms of animal life in that they can: (693.7) 61:1.4 1. Bring forth relatively mature and well-developed offspring. (693.8) 61:1.5 2. Nourish, nurture, and protect their offspring with affectionate regard. (693.9) 61:1.6 3. Employ their superior brain power in self-perpetuation. (693.10) 61:1.7 4. Utilize increased agility in escaping from enemies. (693.11) 61:1.8 5. Apply superior intelligence to environmental adjustment and adaptation. (694.1) 61:1.9 45,000,000 years ago the continental backbones were elevated in association with a very general sinking of the coast lines. Mammalian life was evolving rapidly. A small reptilian, egg-laying type of mammal flourished, and the ancestors of the later kangaroos roamed Australia. Soon there were small horses, fleet-footed rhinoceroses, tapirs with proboscises, primitive pigs, squirrels, lemurs, opossums, and several tribes of monkeylike animals. They were all small, primitive, and best suited to living among the forests of the mountain regions. A large ostrichlike land bird developed to a height of ten feet and laid an egg nine by thirteen inches. These were the ancestors of the later gigantic passenger birds that were so highly intelligent, and that onetime transported human beings through the air. (694.2) 61:1.10 The mammals of the early Cenozoic lived on land, under the water, in the air, and among the treetops. They had from one to eleven pairs of mammary glands, and all were covered with considerable hair. In common with the later appearing orders, they developed two successive sets of teeth and possessed large brains in comparison to body size. But among them all no modern forms existed. (694.3) 61:1.11 40,000,000 years ago the land areas of the Northern Hemisphere began to elevate, and this was followed by new extensive land deposits and other terrestrial activities, including lava flows, warping, lake formation, and erosion. (694.4) 61:1.12 During the latter part of this epoch most of Europe was submerged. Following a slight land rise the continent was covered by lakes and bays. The Arctic Ocean, through the Ural depression, ran south to connect with the Mediterranean Sea as it was then expanded northward, the highlands of the Alps, Carpathians, Apennines, and Pyrenees being up above the water as islands of the sea. The Isthmus of Panama was up; the Atlantic and Pacific Oceans were separated. North America was connected with Asia by the Bering Strait land bridge and with Europe by way of Greenland and Iceland. The earth circuit of land in northern latitudes was broken only by the Ural Straits, which connected the arctic seas with the enlarged Mediterranean. (694.5) 61:1.13 Considerable foraminiferal limestone was deposited in European waters. Today this same stone is elevated to a height of 10,000 feet in the Alps, 16,000 feet in the Himalayas, and 20,000 feet in Tibet. The chalk deposits of this period are found along the coasts of Africa and Australia, on the west coast of South America, and about the West Indies. (694.6) 61:1.14 Throughout this so-called Eocene period the evolution of mammalian and other related forms of life continued with little or no interruption. North America was then connected by land with every continent except Australia, and the world was gradually overrun by primitive mammalian fauna of various types. 2. The Recent Flood Stage The Age of Advanced Mammals (694.7) 61:2.1 This period was characterized by the further and rapid evolution of placental mammals, the more progressive forms of mammalian life developing during these times. (694.8) 61:2.2 Although the early placental mammals sprang from carnivorous ancestors, very soon herbivorous branches developed, and, erelong, omnivorous mammalian families also sprang up. The angiosperms were the principal food of the rapidly increasing mammals, the modern land flora, including the majority of present-day plants and trees, having appeared during earlier periods. (695.1) 61:2.3 35,000,000 years ago marks the beginning of the age of placental-mammalian world domination. The southern land bridge was extensive, reconnecting the then enormous Antarctic continent with South America, South Africa, and Australia. In spite of the massing of land in high latitudes, the world climate remained relatively mild because of the enormous increase in the size of the tropic seas, nor was the land elevated sufficiently to produce glaciers. Extensive lava flows occurred in Greenland and Iceland, some coal being deposited between these layers. (695.2) 61:2.4 Marked changes were taking place in the fauna of the planet. The sea life was undergoing great modification; most of the present-day orders of marine life were in existence, and foraminifers continued to play an important role. The insect life was much like that of the previous era. The Florissant fossil beds of Colorado belong to the later years of these far-distant times. Most of the living insect families go back to this period, but many then in existence are now extinct, though their fossils remain. (695.3) 61:2.5 On land this was pre-eminently the age of mammalian renovation and expansion. Of the earlier and more primitive mammals, over one hundred species were extinct before this period ended. Even the mammals of large size and small brain soon perished. Brains and agility had replaced armor and size in the progress of animal survival. And with the dinosaur family on the decline, the mammals slowly assumed domination of the earth, speedily and completely destroying the remainder of their reptilian ancestors. (695.4) 61:2.6 Along with the disappearance of the dinosaurs, other and great changes occurred in the various branches of the saurian family. The surviving members of the early reptilian families are turtles, snakes, and crocodiles, together with the venerable frog, the only remaining group representative of man’s earlier ancestors. (695.5) 61:2.7 Various groups of mammals had their origin in a unique animal now extinct. This carnivorous creature was something of a cross between a cat and a seal; it could live on land or in water and was highly intelligent and very active. In Europe the ancestor of the canine family evolved, soon giving rise to many species of small dogs. About the same time the gnawing rodents, including beavers, squirrels, gophers, mice, and rabbits, appeared and soon became a notable form of life, very little change having since occurred in this family. The later deposits of this period contain the fossil remains of dogs, cats, coons, and weasels in ancestral form. (695.6) 61:2.8 30,000,000 years ago the modern types of mammals began to make their appearance. Formerly the mammals had lived for the greater part in the hills, being of the mountainous types; suddenly there began the evolution of the plains or hoofed type, the grazing species, as differentiated from the clawed flesh eaters. These grazers sprang from an undifferentiated ancestor having five toes and forty-four teeth, which perished before the end of the age. Toe evolution did not progress beyond the three-toed stage throughout this period. (695.7) 61:2.9 The horse, an outstanding example of evolution, lived during these times in both North America and Europe, though his development was not fully completed until the later ice age. While the rhinoceros family appeared at the close of this period, it underwent its greatest expansion subsequently. A small hoglike creature also developed which became the ancestor of the many species of swine, peccaries, and hippopotamuses. Camels and llamas had their origin in North America about the middle of this period and overran the western plains. Later, the llamas migrated to South America, the camels to Europe, and soon both were extinct in North America, though a few camels survived up to the ice age. (696.1) 61:2.10 About this time a notable thing occurred in western North America: The early ancestors of the ancient lemurs first made their appearance. While this family cannot be regarded as true lemurs, their coming marked the establishment of the line from which the true lemurs subsequently sprang. (696.2) 61:2.11 Like the land serpents of a previous age which betook themselves to the seas, now a whole tribe of placental mammals deserted the land and took up their residence in the oceans. And they have ever since remained in the sea, yielding the modern whales, dolphins, porpoises, seals, and sea lions. (696.3) 61:2.12 The bird life of the planet continued to develop, but with few important evolutionary changes. The majority of modern birds were existent, including gulls, herons, flamingoes, buzzards, falcons, eagles, owls, quails, and ostriches. (696.4) 61:2.13 By the close of this Oligocene period, covering ten million years, the plant life, together with the marine life and the land animals, had very largely evolved and was present on earth much as today. Considerable specialization has subsequently appeared, but the ancestral forms of most living things were then alive. 3. The Modern Mountain Stage Age of the Elephant and the Horse (696.5) 61:3.1 Land elevation and sea segregation were slowly changing the world’s weather, gradually cooling it, but the climate was still mild. Sequoias and magnolias grew in Greenland, but the subtropical plants were beginning to migrate southward. By the end of this period these warm-climate plants and trees had largely disappeared from the northern latitudes, their places being taken by more hardy plants and the deciduous trees. (696.6) 61:3.2 There was a great increase in the varieties of grasses, and the teeth of many mammalian species gradually altered to conform to the present-day grazing type. (696.7) 61:3.3 25,000,000 years ago there was a slight land submergence following the long epoch of land elevation. The Rocky Mountain region remained highly elevated so that the deposition of erosion material continued throughout the lowlands to the east. The Sierras were well re-elevated; in fact, they have been rising ever since. The great four-mile vertical fault in the California region dates from this time. (696.8) 61:3.4 20,000,000 years ago was indeed the golden age of mammals. The Bering Strait land bridge was up, and many groups of animals migrated to North America from Asia, including the four-tusked mastodons, short-legged rhinoceroses, and many varieties of the cat family.* (696.9) 61:3.5 The first deer appeared, and North America was soon overrun by ruminants — deer, oxen, camels, bison, and several species of rhinoceroses — but the giant pigs, more than six feet tall, became extinct. (697.1) 61:3.6 The huge elephants of this and subsequent periods possessed large brains as well as large bodies, and they soon overran the entire world except Australia. For once the world was dominated by a huge animal with a brain sufficiently large to enable it to carry on. Confronted by the highly intelligent life of these ages, no animal the size of an elephant could have survived unless it had possessed a brain of large size and superior quality. In intelligence and adaptation the elephant is approached only by the horse and is surpassed only by man himself. Even so, of the fifty species of elephants in existence at the opening of this period, only two have survived. (697.2) 61:3.7 15,000,000 years ago the mountain regions of Eurasia were rising, and there was some volcanic activity throughout these regions, but nothing comparable to the lava flows of the Western Hemisphere. These unsettled conditions prevailed all over the world. (697.3) 61:3.8 The Strait of Gibraltar closed, and Spain was connected with Africa by the old land bridge, but the Mediterranean flowed into the Atlantic through a narrow channel which extended across France, the mountain peaks and highlands appearing as islands above this ancient sea. Later on, these European seas began to withdraw. Still later, the Mediterranean was connected with the Indian Ocean, while at the close of this period the Suez region was elevated so that the Mediterranean became, for a time, an inland salt sea. (697.4) 61:3.9 The Iceland land bridge submerged, and the arctic waters commingled with those of the Atlantic Ocean. The Atlantic coast of North America rapidly cooled, but the Pacific coast remained warmer than at present. The great ocean currents were in function and affected climate much as they do today. (697.5) 61:3.10 Mammalian life continued to evolve. Enormous herds of horses joined the camels on the western plains of North America; this was truly the age of horses as well as of elephants. The horse’s brain is next in animal quality to that of the elephant, but in one respect it is decidedly inferior, for the horse never fully overcame the deep-seated propensity to flee when frightened. The horse lacks the emotional control of the elephant, while the elephant is greatly handicapped by size and lack of agility. During this period an animal evolved which was somewhat like both the elephant and the horse, but it was soon destroyed by the rapidly increasing cat family. (697.6) 61:3.11 As Urantia is entering the so-called “horseless age,” you should pause and ponder what this animal meant to your ancestors. Men first used horses for food, then for travel, and later in agriculture and war. The horse has long served mankind and has played an important part in the development of human civilization. (697.7) 61:3.12 The biologic developments of this period contributed much toward the setting of the stage for the subsequent appearance of man. In central Asia the true types of both the primitive monkey and the gorilla evolved, having a common ancestor, now extinct. But neither of these species is concerned in the line of living beings which were, later on, to become the ancestors of the human race. (697.8) 61:3.13 The dog family was represented by several groups, notably wolves and foxes; the cat tribe, by panthers and large saber-toothed tigers, the latter first evolving in North America. The modern cat and dog families increased in numbers all over the world. Weasels, martens, otters, and raccoons thrived and developed throughout the northern latitudes.* (698.1) 61:3.14 Birds continued to evolve, though few marked changes occurred. Reptiles were similar to modern types — snakes, crocodiles, and turtles. (698.2) 61:3.15 Thus drew to a close a very eventful and interesting period of the world’s history. This age of the elephant and the horse is known as the Miocene. 4. The Recent Continental-Elevation Stage The Last Great Mammalian Migration (698.3) 61:4.1 This is the period of preglacial land elevation in North America, Europe, and Asia. The land was greatly altered in topography. Mountain ranges were born, streams changed their courses, and isolated volcanoes broke out all over the world. (698.4) 61:4.2 10,000,000 years ago began an age of widespread local land deposits on the lowlands of the continents, but most of these sedimentations were later removed. Much of Europe, at this time, was still under water, including parts of England, Belgium, and France, and the Mediterranean Sea covered much of northern Africa. In North America extensive depositions were made at the mountain bases, in lakes, and in the great land basins. These deposits average only about two hundred feet, are more or less colored, and fossils are rare. Two great fresh-water lakes existed in western North America. The Sierras were elevating; Shasta, Hood, and Rainier were beginning their mountain careers. But it was not until the subsequent ice age that North America began its creep toward the Atlantic depression. (698.5) 61:4.3 For a short time all the land of the world was again joined excepting Australia, and the last great world-wide animal migration took place. North America was connected with both South America and Asia, and there was a free exchange of animal life. Asiatic sloths, armadillos, antelopes, and bears entered North America, while North American camels went to China. Rhinoceroses migrated over the whole world except Australia and South America, but they were extinct in the Western Hemisphere by the close of this period. (698.6) 61:4.4 In general, the life of the preceding period continued to evolve and spread. The cat family dominated the animal life, and marine life was almost at a standstill. Many of the horses were still three-toed, but the modern types were arriving; llamas and giraffelike camels mingled with the horses on the grazing plains. The giraffe appeared in Africa, having just as long a neck then as now. In South America sloths, armadillos, anteaters, and the South American type of primitive monkeys evolved. Before the continents were finally isolated, those massive animals, the mastodons, migrated everywhere except to Australia. (698.7) 61:4.5 5,000,000 years ago the horse evolved as it now is and from North America migrated to all the world. But the horse had become extinct on the continent of its origin long before the red man arrived. (698.8) 61:4.6 The climate was gradually getting cooler; the land plants were slowly moving southward. At first it was the increasing cold in the north that stopped animal migrations over the northern isthmuses; subsequently these North American land bridges went down. Soon afterwards the land connection between Africa and South America finally submerged, and the Western Hemisphere was isolated much as it is today. From this time forward distinct types of life began to develop in the Eastern and Western Hemispheres. (699.1) 61:4.7 And thus does this period of almost ten million years’ duration draw to a close, and not yet has the ancestor of man appeared. This is the time usually designated as the Pliocene. 5. The Early Ice Age (699.2) 61:5.1 By the close of the preceding period the lands of the northeastern part of North America and of northern Europe were highly elevated on an extensive scale, in North America vast areas rising up to 30,000 feet and more. Mild climates had formerly prevailed over these northern regions, and the arctic waters were all open to evaporation, and they continued to be ice-free until almost the close of the glacial period. (699.3) 61:5.2 Simultaneously with these land elevations the ocean currents shifted, and the seasonal winds changed their direction. These conditions eventually produced an almost constant precipitation of moisture from the movement of the heavily saturated atmosphere over the northern highlands. Snow began to fall on these elevated and therefore cool regions, and it continued to fall until it had attained a depth of 20,000 feet. The areas of the greatest depth of snow, together with altitude, determined the central points of subsequent glacial pressure flows. And the ice age persisted just as long as this excessive precipitation continued to cover these northern highlands with this enormous mantle of snow, which soon metamorphosed into solid but creeping ice. (699.4) 61:5.3 The great ice sheets of this period were all located on elevated highlands, not in mountainous regions where they are found today. One half of the glacial ice was in North America, one fourth in Eurasia, and one fourth elsewhere, chiefly in Antarctica. Africa was little affected by the ice, but Australia was almost covered with the antarctic ice blanket. (699.5) 61:5.4 The northern regions of this world have experienced six separate and distinct ice invasions, although there were scores of advances and recessions associated with the activity of each individual ice sheet. The ice in North America collected in two and, later, three centers. Greenland was covered, and Iceland was completely buried beneath the ice flow. In Europe the ice at various times covered the British Isles excepting the coast of southern England, and it overspread western Europe down to France. (699.6) 61:5.5 2,000,000 years ago the first North American glacier started its southern advance. The ice age was now in the making, and this glacier consumed nearly one million years in its advance from, and retreat back toward, the northern pressure centers. The central ice sheet extended south as far as Kansas; the eastern and western ice centers were not then so extensive. (699.7) 61:5.6 1,500,000 years ago the first great glacier was retreating northward. In the meantime, enormous quantities of snow had been falling on Greenland and on the northeastern part of North America, and erelong this eastern ice mass began to flow southward. This was the second invasion of the ice. (699.8) 61:5.7 These first two ice invasions were not extensive in Eurasia. During these early epochs of the ice age North America was overrun with mastodons, woolly mammoths, horses, camels, deer, musk oxen, bison, ground sloths, giant beavers, saber-toothed tigers, sloths as large as elephants, and many groups of the cat and dog families. But from this time forward they were rapidly reduced in numbers by the increasing cold of the glacial period. Toward the close of the ice age the majority of these animal species were extinct in North America. (700.1) 61:5.8 Away from the ice the land and water life of the world was little changed. Between the ice invasions the climate was about as mild as at present, perhaps a little warmer. The glaciers were, after all, local phenomena, though they spread out to cover enormous areas. The coastwise climate varied greatly between the times of glacial inaction and those times when enormous icebergs were sliding off the coast of Maine into the Atlantic, slipping out through Puget Sound into the Pacific, and thundering down Norwegian fiords into the North Sea. 6. Primitive Man in the Ice Age (700.2) 61:6.1 The great event of this glacial period was the evolution of primitive man. Slightly to the west of India, on land now under water and among the offspring of Asiatic migrants of the older North American lemur types, the dawn mammals suddenly appeared. These small animals walked mostly on their hind legs, and they possessed large brains in proportion to their size and in comparison with the brains of other animals. In the seventieth generation of this order of life a new and higher group of animals suddenly differentiated. These new mid-mammals — almost twice the size and height of their ancestors and possessing proportionately increased brain power — had only well established themselves when the Primates, the third vital mutation, suddenly appeared. (At this same time, a retrograde development within the mid-mammal stock gave origin to the simian ancestry; and from that day to this the human branch has gone forward by progressive evolution, while the simian tribes have remained stationary or have actually retrogressed.) (700.3) 61:6.2 1,000,000 years ago Urantia was registered as an inhabited world. A mutation within the stock of the progressing Primates suddenly produced two primitive human beings, the actual ancestors of mankind. (700.4) 61:6.3 This event occurred at about the time of the beginning of the third glacial advance; thus it may be seen that your early ancestors were born and bred in a stimulating, invigorating, and difficult environment. And the sole survivors of these Urantia aborigines, the Eskimos, even now prefer to dwell in frigid northern climes. (700.5) 61:6.4 Human beings were not present in the Western Hemisphere until near the close of the ice age. But during the interglacial epochs they passed westward around the Mediterranean and soon overran the continent of Europe. In the caves of western Europe may be found human bones mingled with the remains of both tropic and arctic animals, testifying that man lived in these regions throughout the later epochs of the advancing and retreating glaciers. 7. The Continuing Ice Age (700.6) 61:7.1 Throughout the glacial period other activities were in progress, but the action of the ice overshadows all other phenomena in the northern latitudes. No other terrestrial activity leaves such characteristic evidence on the topography. The distinctive boulders and surface cleavages, such as potholes, lakes, displaced stone, and rock flour, are to be found in connection with no other phenomenon in nature. The ice is also responsible for those gentle swells, or surface undulations, known as drumlins. And a glacier, as it advances, displaces rivers and changes the whole face of the earth. Glaciers alone leave behind them those telltale drifts — the ground, lateral, and terminal moraines. These drifts, particularly the ground moraines, extend from the eastern seaboard north and westward in North America and are found in Europe and Siberia. (701.1) 61:7.2 750,000 years ago the fourth ice sheet, a union of the North American central and eastern ice fields, was well on its way south; at its height it reached to southern Illinois, displacing the Mississippi River fifty miles to the west, and in the east it extended as far south as the Ohio River and central Pennsylvania. (701.2) 61:7.3 In Asia the Siberian ice sheet made its southernmost invasion, while in Europe the advancing ice stopped just short of the mountain barrier of the Alps. (701.3) 61:7.4 500,000 years ago, during the fifth advance of the ice, a new development accelerated the course of human evolution. Suddenly and in one generation the six colored races mutated from the aboriginal human stock. This is a doubly important date since it also marks the arrival of the Planetary Prince. (701.4) 61:7.5 In North America the advancing fifth glacier consisted of a combined invasion by all three ice centers. The eastern lobe, however, extended only a short distance below the St. Lawrence valley, and the western ice sheet made little southern advance. But the central lobe reached south to cover most of the State of Iowa. In Europe this invasion of the ice was not so extensive as the preceding one. (701.5) 61:7.6 250,000 years ago the sixth and last glaciation began. And despite the fact that the northern highlands had begun to sink slightly, this was the period of greatest snow deposition on the northern ice fields. (701.6) 61:7.7 In this invasion the three great ice sheets coalesced into one vast ice mass, and all of the western mountains participated in this glacial activity. This was the largest of all ice invasions in North America; the ice moved south over fifteen hundred miles from its pressure centers, and North America experienced its lowest temperatures. (701.7) 61:7.8 200,000 years ago, during the advance of the last glacier, there occurred an episode which had much to do with the march of events on Urantia — the Lucifer rebellion. (701.8) 61:7.9 150,000 years ago the sixth and last glacier reached its farthest points of southern extension, the western ice sheet crossing just over the Canadian border; the central coming down into Kansas, Missouri, and Illinois; the eastern sheet advancing south and covering the greater portion of Pennsylvania and Ohio. (701.9) 61:7.10 This is the glacier that sent forth the many tongues, or ice lobes, which carved out the present-day lakes, great and small. During its retreat the North American system of Great Lakes was produced. And Urantian geologists have very accurately deduced the various stages of this development and have correctly surmised that these bodies of water did, at different times, empty first into the Mississippi valley, then eastward into the Hudson valley, and finally by a northern route into the St. Lawrence. It is thirty-seven thousand years since the connected Great Lakes system began to empty out over the present Niagara route. (702.1) 61:7.11 100,000 years ago, during the retreat of the last glacier, the vast polar ice sheets began to form, and the center of ice accumulation moved considerably northward. And as long as the polar regions continue to be covered with ice, it is hardly possible for another glacial age to occur, regardless of future land elevations or modification of ocean currents. (702.2) 61:7.12 This last glacier was one hundred thousand years advancing, and it required a like span of time to complete its northern retreat. The temperate regions have been free from the ice for a little over fifty thousand years. (702.3) 61:7.13 The rigorous glacial period destroyed many species and radically changed numerous others. Many were sorely sifted by the to-and-fro migration which was made necessary by the advancing and retreating ice. Those animals which followed the glaciers back and forth over the land were the bear, bison, reindeer, musk ox, mammoth, and mastodon. (702.4) 61:7.14 The mammoth sought the open prairies, but the mastodon preferred the sheltered fringes of the forest regions. The mammoth, until a late date, ranged from Mexico to Canada; the Siberian variety became wool covered. The mastodon persisted in North America until exterminated by the red man much as the white man later killed off the bison. (702.5) 61:7.15 In North America, during the last glaciation, the horse, tapir, llama, and saber-toothed tiger became extinct. In their places sloths, armadillos, and water hogs came up from South America. (702.6) 61:7.16 The enforced migration of life before the advancing ice led to an extraordinary commingling of plants and of animals, and with the retreat of the final ice invasion, many arctic species of both plants and animals were left stranded high upon certain mountain peaks, whither they had journeyed to escape destruction by the glacier. And so, today, these dislocated plants and animals may be found high up on the Alps of Europe and even on the Appalachian Mountains of North America. (702.7) 61:7.17 The ice age is the last completed geologic period, the so-called Pleistocene, over two million years in length. (702.8) 61:7.18 35,000 years ago marks the termination of the great ice age excepting in the polar regions of the planet. This date is also significant in that it approximates the arrival of a Material Son and Daughter and the beginning of the Adamic dispensation, roughly corresponding to the beginning of the Holocene or postglacial period.* (702.9) 61:7.19 This narrative, extending from the rise of mammalian life to the retreat of the ice and on down to historic times, covers a span of almost fifty million years. This is the last — the current — geologic period and is known to your researchers as the Cenozoic or recent-times era. (702.10) 61:7.20 [Sponsored by a Resident Life Carrier.]

This dissertation addresses the biogeographic history of the Araceae family and of one of its largest genera, Alocasia. With >3300 species, Araceae are among the largest families of flowering plants. It is the monocot lineage with the deepest fossil record, reaching back to the Early Cretaceous. Araceae are distributed worldwide, but >3100 species occur in the tropical regions of the Americas, Asia, Africa, and Australia; most fossils from the Late Cretaceous and many younger ones come from the temperate zone in the northern hemisphere, implying much extinction and range expansion. Most subfamilies are pantropically distributed, and almost all genera are restricted to one continent. Alocasia comprises 113 species, many as yet undescribed, making it the 7 th -largest genus of the Araceae. Many species are ornamentals, and two species are of interest for man, either for food (giant taro) or in local cultures (Chinese taro). The origin of these species was not known. Alocasia is distributed in Southeast Asia from India to Australia, with species occurring on all islands of the Malay Archipelago. This region has a complex geologic history shaped by the collision of the Eurasian, the Pacific, and the Indo-Australian plate. The Malesian flora and fauna comprises Laurasian and Gondwanan elements, reflecting the influence of changing sea levels, uplift and submergence of islands, and other tectonic movement. In this thesis, I used molecular phylogenetics, Bayesian divergence dating, ancestral area reconstruction to understand the past distribution of the Araceae family and the Alocasia clade in the context of past continent movements and climate history. For the family analysis, existing chloroplast DNA matrices were augmented so that all Araceae genera were represented by one or more species, with a focus on covering geographic disjunctions, especially between continents. Divergence dating relied on seven confidently assigned fossil constraints, comparing uniform and gamma-shaped prior distributions on fossil ages, as well as several molecular clock models. Biogeographic analyses were performed in a model-based likelihood framework that took into account past dispersal routes based on continent connectivity and climate. I also integrated fossils into the ancestral area reconstruction, either simulating extinct or still existing ranges, and then compared results to those obtained from analyses without fossils. To study the morphology and ecology of Alocasia, fieldwork was conducted in Malaysia and herbarium work in Germany, the Netherlands, Indonesia, Malaysia, and Singapore. Maximum likelihood phylogenies were inferred based on chloroplast and nuclear loci, sequenced for 71 species of Alocasia plus 25 outgroup species from 16 genera. Bayesian divergence dating of the nuclear phylogeny relied on one fossil constraint and ancestral areas were reconstructed using parsimony- and likelihood-based methods. The Araceae diverged from the remaining Alismatales in the Early Cretaceous (ca. 135 Ma ago), and all eight subfamilies originated before the Cenozoic. The earliest lineages are inferred to have occurred in Laurasia (based on fossils and tree topology), and most lineages reached Africa, South America, Southeast Asia, and Australia during the Paleogene and Neogene. Many clades experienced extinction in the temperate regions of the northern hemisphere during the Oligocene climate cooling. Two continentally disjunct genera (Nephthytis and Philodendron) are polyphyletic and need taxonomic rearrangement. Plastid substitution rates are exceptionally high in free-floating and water-associated Araceae. Ancestral area reconstructions obtained when fossil (no longer occupied) ranges where included in the analyses were more plausible than those without fossil ranges. This is not a trivial result because only in a quantitative (computer-based) analysis is it possible for fossil ranges to influence results (here areas) at distant nodes in the phylogenetic tree. The nuclear and plastid phylogenies of Alocasia revealed the polyphyly of the two genera Alocasia and Colocasia; to achieve monophyly, two species (Alocasia hypnosa and Colocasia gigantea) have to be moved to other genera. There were strong incongruencies between phylogenies from the two partitions: The chloroplast data reflect geographical proximity, the nuclear morphological similarity. This may indicate hybridization events followed by chloroplast capture. Based on the nuclear tree, Alocasia split from its sister group by the end of the Oligocene (ca. 24 Ma) and colonized the Malay Archipelago from the Asian mainland. Borneo played a central role, with 11–13 of 18–19 inferred dispersal events originating there. The Philippines were reached from Borneo 4–5 times in the late Miocene and early Pliocene, and the Asian mainland 6–7 times during the Pliocene. The geographic origin of two domesticated species could be resolved: Giant taro originated on the Philippines and Chinese taro on the Asian mainland.

The drift history of Gondwana following the break-up of Rodinia (or perhaps Pannotia) to the amalgamation into Pangaea has great implications in many disciplines in Earth sciences, but remains largely unknown. Among the apparent polar wander (APW) paths published for Gondwana in the last few decades, large discrepancies exist (sometimes up to thousands of kilometres). The mid Palaeozoic segment of the APW path is particularly problematic, and two primary schools of thought arise. Some authors favour a Silurian – Devonian loop in their APW path passing through southern South America (on a reconstruction of Gondwana), whereas others draw a path directly through Africa during this period. The main controversy stems essentially from whether or not palaeomagnetic data from eastern Australia are incorporated in order to compensate for the lack of mid Palaeozoic data. Determining whether the terranes of the Southern Tasmanides are (para-)autochthonous or allochthonous in origin is therefore of crucial importance and a matter of intense debate. The aim of the work presented herein is to palaeomagnetically define the positions of these terranes throughout the Palaeozoic in order to better constrain the complex tectonic history of this region and to help clarifying the APW path of Gondwana. The construction of an APW path is discussed herein. An attempt is made to determine whether only “objective” criteria can be employed to select data used to draw an APW path. However, it is shown that the palaeomagnetic database has not enough entries. Subjective data selection must be introduced leading to two end-members: the X-type and the Y-type, thought to be best illustrated by the X-path proposed by Bachtadse & Briden (1991) and the Y-path proposed by Schmidt et al. (1990). These two models are, therefore, used in the discussion of the results obtained for this study. The Southern Tasmanides had a complex tectonic history with several orogenic events throughout the Palaeozoic. The sampling coverage carried out for this study comprises fifty localities (289 sites, 1576 cores, 3969 specimens; see table 1, pages 54-55) distributed along an east-west transect across most of the subdivisions of the Southern Tasmanides. The sampled localities are gathered in three main areas: the Broken Hill area, the Mount Bowen area, and the Molong area, which are situated where no published palaeomagnetic studies were previously available providing, therefore, new information. Sampling and laboratory procedures have been carried out using standard techniques. In particular, detailed stepwise thermal demagnetisation, principal component analysis, anisotropy of magnetic susceptibility and rock magnetic measurements have been systematically employed. The routine measurement of the anisotropy of magnetic susceptibility allowed drawing the first maps of the magnetic fabrics throughout the region. A strong correlation between the magnetic fabrics and the main tectonic structures corroborates the existence of cross-structures (E-W) in the Southern Tasmanides. The directions of magnetisation obtained yielded much information, despite poor quality. The effects of weathering are deep, intense and widespread. For example, most of the samples from the Mount Arrowsmith Formation (localities ARR & ARO) and the Funeral Creek Limestone (FUN) in the Broken Hill area (western New South Wales) are totally remagnetised, as well as some from the Mitchell Formation (MIT) in the Molong area (eastern New South Wales). Secondary magnetisations are also largely responsible for the bad results obtained in most of the fifty localities studied. Intermediate directions of magnetisation are common and often result in significant data scattering, as illustrated for instance by results from the Kandie Tank Limestone (KAN; Broken Hill area) or the Ambone and Ural Volcanics (HOP, BOW, SHE; Mount Bowen area). In general, it has not been possible to precise the remagnetisation process leading to those scattering. Nevertheless, a major remagnetisation event, probably thermo-chemical in origin, has been also recognised. This event is thought to be Oligocene in age and triggered by changes in geothermal gradient prior to the onset of hot spot volcanism in the Molong area. The existence of Jurassic overprints are also suggested, in particular in the Broken Hill area, possibly in association of intrusion of mafic dykes. All other magnetic components described herein are considered Palaeozoic in age, but further constraints on age are very difficult to establish since field tests are most often not significant. Palaeopoles obtained from three localities, however, are believed to correspond to primary magnetisations. The pole from the Late Cambrian Cupala Creek Formation (CUP), confirmed by a positive unconformity test, implies that this zone can be regarded fixed relative to the craton since the Late Cambrian. In the Early Devonian Mount Daubeny Formation (DAU), the applied fold test, contact test and conglomerate test indicate the primary origin of the magnetisation carried by haematite. The corresponding pole (DAU) is, however, significantly distinct from the VGP deduced from the Early Devonian Ural Volcanics (MER) showing that at least one of the two localities has been rotated. The MER pole agrees with the remagnetisation pole associated with the Cupala Creek Formation, and favours the X-type of APW path proposed by Bachtadse & Briden (1991) for Gondwana. The outcome of this agreement contradicts the Y-type path and the existence of a Silurian – Devonian loop mainly anchored on the Early Devonian Snowy River Volcanics pole obtained by Schmidt et al. (1987). Invocation of terrane rotation, arising possibly from a pull-apart basin, may explain the discrepancy between the pole from Mount Daubeny Formation and the X-path. The most significant finding of this study is the widespread terrane rotation. This conclusion is based upon the inability of intermediate directions of magnetisation, alternate APW path for Gondwana, true polar wander or non-dipole field contribution to correctly explain the distribution of these new data. Consequently, one has to admit that block translation and rotation occurred in the Southern Tasmanides in the first half of the Palaeozoic Era and perhaps up to the Early Carboniferous. A possible scenario concerning the tectonic arrangement of blocks in the Southern Tasmanides is presented in conclusion. This palinspastic model involves block translation in the Siluro-Devonian, and rotation in the Early and more probably Middle Devonian, with late tectonic displacements and rotations in the South-Western Belt of the Lachlan Orogen in the Late Devonian to Early Carboniferous.

The assumption that stationary hotspots underlie the Earth’s lithospheric plates has been most important in the development of the theory of plate tectonics. According to the fixed hotspot hypothesis seamount trails are formed by volcanism penetrating the lithospheric plates whilst moving over ”hotspots”of upwelling mantle. In turn, the azimuths and age progressions of seamount trails can be used to quantify plate motions with respect to an independent reference frame of hotspots in the mantle. Also, assuming fixed hotspots, the direction of characteristic remanent magnetization in the basalts acquired during cooling should always be the same. Even if due to plate motion the products of the hotspot are located far away from the position of the hotspot itself, paleomagnetic studies on the basalts must always provide the position of the hotspot itself. Recently the question arose, why a hotspot with its origin deep in the mantle would not get advected in the convecting mantle of the Earth. - In this thesis a possible motion of the Kerguelen hotspot in the southern Indian Ocean and of the Louisville hotspot in the Pacific has been studied. The Kerguelen hotspot is active since approximately 117 Ma. Since then it formed the Kerguelen Plateau and the Broken Ridge in the southern Indian Ocean as well as the Ninetyeast Ridge, which is the hotspot track going north up to India, and the Ramajal Traps in India. Drilling into basement rocks of Broken Ridge and the Kerguelen Plateau was aim of the Ocean Drilling Program, Leg 183, from December 1998 to February 1999. Eight sites have been drilled. In seven of the sites also the sediments have been recovered. In this thesis, a possible motion of the Kerguelen hotspot has been studied by determining its paleolatitudes. First, basalts from the Kerguelen Plateau have been studied paleomagnetically to compare the paleolatitudes with the latitude of the hotspot itself. Basement from a drillsite on the central Kerguelen Plateau (Site 1138) and of a site on the northern Kerguelen Plateau (Site 1140) were suitable for a determination of paleolatitudes. A sufficient number of independent lavaflows has been penetrated and sampled there to properly average out paleosecular variation, an important requirement for determining paleolatitudes. The characteristic magnetization from the subaerial Site 1138 with AA- and Pahoehoe lava and of the submarine Site 1140 with its pillow basalts is carried by magnetite and titanomagnetites and -maghemites and consists of a single remanence component with sometimes a small viscous overprint, that could easily be removed during demagnetization. Stepwise demagnetization in an alternating field and stepwise heating of the specimens provided the inclination value of the characteristic magnetization very precisely with small error. Conversion of the mean-site inclination into the paleolatitude of a site provided a latitude of λ = 43.6◦S (max.: 47.8◦S; min.: 37.9◦S) for Site 1138 on the central Kerguelen Plateau and a latitude of λ = 35.8◦S (max: 43.0◦S; min.: 28.9◦S) for Site 1140 on the northern Kerguelen Plateau. In Site 1136 on the southern Kerguelen Plateau only two lava flows have been sampled. Therefore paleosecular variation could not be averaged out properly. Site 1142 on the Broken Ridge has been tilted and deformed tectonically after its formation, as was found from seismic explorations prior to drilling, and the inclination of the magnetization could therefore not be used for a determination of paleolatitudes. Compared to the latitude of the Kerguelen hotspot at 49◦S, the paleolatitudes of the central and northern Kerguelen Plateau are further north. This result agrees with previous paleomagnetic studies on the southern Kerguelen Plateau and the Ninetyeast Ridge, where paleolatitudes have been found that indicate also a formation north of the present-day hotspot position. This difference indicates a southward movement of the hotspot since the Cretaceous relative to the spin axis of the Earth. The motion can be explained with a rotation of the whole mantle of the Earth relative to the spin axis (true polar wander) or with a motion of the hotspot within the Earth’s mantle. Therefore, the possibility was studied whether true polar wander can be responsible for the difference between the paleomagnetic data and the present-day latitude of the hotspot. Three independently obtained true polar wander paths have been used, that describe the motion of the whole mantle (with the hotspots) relative to the rotation or dipole axis. All three curves point to a shift of the mantle at the time when the central and southern Kerguelen Plateau formed in such a way that higher southern paleolatitudes should be observed. This prediction is just the opposite to what was found in the paleomagnetic studies. The Cenozoic parts of the three experimentally obtained true polar wander paths roughly agree within their uncertainties with a numerically calculated path that accounts for changes of moments of inertia of the mantle. This means that the difference between paleomagnetic data and the present-day position of the hotspot can not be explained by true polar wander. The next starting point to explain the discrepancy is hotspot motion. For the determination of hotspot drift, geodynamic modeling has been carried out. Assuming that a mantle plume rising from the core-mantle boundary is advected in an convecting mantle, a hotspot sould move relative to the surface of the Earth. Seismic tomography models were converted into density models of the Earth’s mantle. Then a velocity field derived from the mass motion due to the density heterogeneities is calculated. The rising mantle plume is then inserted into the model and becomes advected in the velocity field. Seven different tomographic models have been used to obtain velocity fields. All seven models result in a southward motion for the Kerguelen hotspot since its first appearance approximately 117 Ma ago. The motion is in a similar direction for the different models, and its magnitude varies from 5 to over 10 degrees. So far, the program to model the hotspot drift assumed a constant viscosity within the rising plume. More realistic is the assumption of a depth-dependent plume radius, based on estimates of temperature- and hence viscosity variations within the plume. This has been integrated as a subroutine into the program. The plume radius affects the buoyancy of the plume. A plume with larger radius rises faster through the mantle, and will hence have a stronger tendency to straighten up. In contrast, a plume with smaller radius rises slowly and will be influenced more strongly by the velocity field of the mantle. Allowing for the variation of viscosity within the plume, the hotspot motion was calculated again. A comparison of the resulting hotspot motion for various input parameters showed that the result is rather independent of the parameters. The calculations also yield a southward motion of 5 to 10 degrees, only the shape of the hotspot path is somewhat changed. This southward motion of the Kerguelen hotspot by 5 to 10 degrees can explain the difference between the paleomagnetic data and the present-day position of the hotspot. Even combined with true polar wander it fits the paleomagnetic results, although true polar wander, taken by itself, even increases the difference that has to be explained. The consistency of paleomagnetic results with the model calculations allows the conclusion that the Kerguelen hotspot indeed moved southward by some degrees since its first occurence 117 Ma ago. A magnetostratigraphy has been made using the sediments of ODP Leg 183. It yielded a contribution to the age dating of the basalts prior to 40Ar/39Ar dating. Paleomagnetic studies on the sediments contributed to a combined Bio/Magnetostratigraphy. The stratigraphy helps to determine the minimal age of the underlying basalts. Using the reversals found in the magnetization and a correlation with the paleontological data, the lowermost sediments of Site 1136 (southern Kerguelen Plateau) are dated to have an age in the Early Cretaceous, Site 1138 (central Kerguelen Plateau) in the Late Cretaceous, and Site 1140 (northern Kerguelen Plateau) in the Oligocene. These results are meanwhile confirmed by precise 40Ar/39Ar age dating of the basement yielding an age of 100 Ma for Site 1138 and of 35 Ma for Site 1140. The Ontong Java Plateau, a Large Igneous Province in the western Pacific, was thought to be formed by the rising mantle plume of the Louisville hotspot approximately 120 Ma ago. However, according to a recent plate reconstruction, the plateau has been formed well to the north of the location of this hotspot. In this thesis it could be shown that the formation of the Ontong Java Plateau by the Louisville hotspot is possible if hotspot motion in the convecting mantle is allowed. For this purpose, the motion of the Louisville hotspot for the last 120 Ma years has been modeled, using the same method as already applied for the Kerguelen hotspot. The calculations indicate, that the Louisville hotspot has probably shifted by some degrees to the south since its first occurence approximately 120 Ma ago. There is a considerable variation between different model results, though. The Louisville hotspot is now located too far south to be responsible for the formation of the Plateau. However, it could have been in the right place at the time of the formation 120 Ma ago if hotspot motion is considered. This is an example that the drift of hotspots can affect plate tectonics and tectonic reconstructions and that it should be considered.
