Dr. Joanne BallardJoanne has a PhD in Geography from the University of Tennessee with specializations in Biogeography and Quaternary Environments, advised by Dr Sally Horn, palynologist.  She has a M.S. in Geology from the University of Cincinnati, studying under glaciologist Dr. Thomas Lowell.  She has also worked as an Archaeologist for the Tennessee Valley Authority as a Database Analyst and Mapping expert.  In addition, Joanne worked for the US Census Bureau as an Analyst and Cartographic Technician, giving technical support, troubleshooting, and training personnel on addressing projects.  Currently, Joanne is serving as a Naturalist at a local museum, and working with Czech colleagues on YDB research led by Dr. Evzen Stuchlik at the Czech Academy of the Sciences.  Joanne is a catastrophist, and collaborates with the Comet Research Group.Joanne has been intrigued with the causation for the megafauna extinction since the 1990s.  She met Rick Firestone at the Mammoth Conference in 2005 at Hot Springs, SD.  When he and others presented their hypothesis on a bolide strike as causation for the Younger Dryas onset (Firestone et al. 2007), she wanted to look for evidence. Lake mud contains various proxies that help us gain insights into past environments, such as charcoal (wildfires), pollen and macrofossils (vegetation), diatoms, chironomids (climate) and chemistry--isotopes and elements. Lake mud is considered less disturbed (such as by roots, earthworms, freeze/thaw) than terrestrial sediment or soil.  At UC, she and her team drilled through the ice to collect cores from four lakes near Flint, Michigan, two of which (Slack and Swift Lakes) are adjacent to the Gainey archaeological site mentioned by Firestone et al. (2007).  At UT, she studied lake sediments from sites in the southeastern USA.   She discovered a new proxy for wildfires--possibly catastrophic wildfires--which are siliceous aggregates. These form in wood ash.  After a tree burns to ash, the silica phytoliths that were part of the structure of the tree are deposited with the wood ash. When that highly alkaline ash gets wet, it causes the phytoliths to dissolve, and the silica gel percolates down through the ash and then hardens up around silt or other particles in the sediment.  Five of six lakes sampled across eastern North America showed siliceous aggregates around the time of the onset of the Younger Dryas, suggesting widespread, catastrophic wildfires.  However, more work needs to be done to support this interpretation.Joanne has also researched Usselo Horizon sites (typically YDB-age black mats) in The Netherlands and Belgium to understand the events that triggered the onset of the Younger Dryas (12,900 - 11,600 BP).  At four Usselo horizon sites across the NL and BE, she found fused quartz, soot, charcoal, melt glass and sponge spicules.See her PPT presentation "Usselo Horizon Presentation" here:https://www.researchgate.net/profile/Joanne-Ballard/researchDid humans tame woolly mammoths?  See the discussion here with 821 postshttps://www.researchgate.net/topicshttps://www.researchgate.net/post/Did-humans-tame-woolly-mammoths-or-other-megafaunaJoanne's dissertation can be accessed and downloaded for free here:https://trace.tennessee.edu/utk_graddiss/3492/Evidence of Late Quaternary Fires from Charcoal and Siliceous Aggregates in Lake Sediments in the Eastern U.S.A.Her MS thesis can be accessed for free here: https://etd.ohiolink.edu/acprod/odb_etd/etd/r/1501/10?clear=10&p10_accession_num=ucin1250268463A Lateglacial Paleofire Record for East-central MichiganRick Firestone's paper:https://www.pnas.org/doi/10.1073/pnas.0706977104    Evidence for an extraterrestrial impact 12,900 years ago that contributed to the megafaunal extinctions and the Younger Dryas cooling-- Sent with Tuta; enjoy secure & ad-free emails: https://tuta.comBecome a supporter of this podcast: https://www.spreaker.com/podcast/earth-ancients--2790919/support.

Tyler Stone (@TylerStoneArt) joins Josiah to discuss his work as a freelance paleoartist. Paleoart (scientific illustration of prehistoric life) is a field with an interesting relationship between art and hard sciences. They discuss this relationship and the nitty gritty of the business side of paleoart, before delving into the challenges of being a science communicator in a field that attracts conspiracy theories, and how AI image generation is impacting the field.Follow Tyler on Twitter @TylerStoneArt // TikTok @TylerStoneArt // Instagram @TylerStoneArtFind more of Tyler's work: https://tylerstoneart.wordpress.comBecome a Fruitless Patron here: https://www.patreon.com/user?u=11922141Check out Fruitless on YouTubeFind more of Josiah's work: https://linktr.ee/josiahwsuttonFollow Josiah on Twitter @josiahwsuttonMedia referencedTyler's animation of the evolution of whales, "From Feet to Flippers: The Evolution of Whales," https://www.youtube.com/watch?v=UKbC7QSjWfEOld episode of Very Legal, Very Cool, "sh*tty creationism," where we discussed the Creation Museum and the Ark Encounter, https://share.transistor.fm/s/96070284A short video by Tom Scott about the Crystal Palace dinosaurs Tyler discusses briefly, "The Scientifically Inaccurate Dinosaurs That Must Stay That Way," https://www.youtube.com/watch?v=QWItLyDzMyE.

Darwin Day is upon us for the fourth time! To celebrate, let's follow Charles Darwin on the first part of his famous voyage between late 1831 and early 1832. We'll see him pour over cuttlefish, travel with veterans of the Napoleonic Wars and arrive in a young Brazilian Empire... Sources for this episode: Bannerman, W. M., Lobban, R. A. and Shaw, C.

It takes our sun 220 million years to orbit around the middle of our home galaxy. But that kind of timescale can be difficult to picture. So, using the International Stratigraphy Chart as a guidance for what different time periods mean in terms of millions of years, let's zoom out to the scale of a galactic year and see what happened in Earth's prehistory one cycle ago, two and so on.

An environmental expert says there's an extra benefit to lowering speed limits- a reduction in carbon emissions. The argument being made is that cars that drive at slower speeds use less fuel and emit less carbon dioxide, which is better for the environment.  AUT professor of biogeography Len Gillman says SUV and other high-emission vehicle drivers need to do their part to cut CO2 output. Len Gillman says reducing speed limits is more equitable than taxing fuel, because low-income drivers will be hit the hardest. LISTEN ABOVESee omnystudio.com/listener for privacy information.

Dennis McCarthy is a writer, historian, and independent researcher who, in the process of tracing Hamlet's origin, ended up unwinding the entire legend of Shakespeare. Digging deeper into the history of Shakespeare's plays alongside collaborators June Schlueter and Michael Blanding, McCarthy uncovered evidence that all but two of Shakespeare's plays were written by Sir Thomas North, an English translator, lawyers, and justice of the peace. We dig into the evidence for the overlap between the two figures, unpack the myth of the lone genius, and seek to understand how the origin of ideas is driven by the sum total of the biogeographic connections that impinge on a given time and place.

Hello everyone and welcome to Episode Seventy Seven!  And I hope you all remain safe and healthy out there, and I want to wish all of you a happy, healthy, and prosperous new year. It's the first week of February and it's good to be back home and to be turning out another episode, after being away for nearly a month in Peru.  It was an interesting trip, to say the least, with a lot of travel issues going both down and back.  I'll spare you the details, but I am beginning to suspect that the golden age of air travel is behind us.  All travel issues aside it was a great trip to Peru, and across 25 days and two back-to-back tour groups we managed to find a total of six bushmasters.  Pretty incredible and I'm still processing all of that.  Needless to say, I recorded segments with some of the folks who encountered their first bushmaster, and I will put that out sometime in the next few months. So Much Pingle Patrons!  I want to give a shout-out to Craig Howard, the show's newest patron.  Craig was on our first Peru tour last month and he took some awesome photos, I especially liked some of his frog shots.  It was good to meet you Craig, and thanks so much for your support. And if you're out there listening and you would like to kick in a few bucks, it's easy to do, you simply go to the So Much Pingle Patreon page. You can support the show for as little as three bucks a month – less than a fancy cup of coffee! You can also support the show via one-time contributions via PayPal or Venmo (please contact me via email to somuchpingle@gmail.com). Well, here we are again with another edition of Herp Science Sunday with Dr. Alex Krohn.  That's right, two in a row, even if they are a month apart, and, this one again features a guest from Australia.  As I said before, this is more by accident than design, but Alex and I are happy about it and we hope you are as well.  Our guest this week is Jules Farquhar, a doctoral candidate in the School of Biological Sciences at Monash University in Victoria, Australia.  Jules is a co-author on a paper published in the Journal of Biogeography last year entitled “Using Crowd-sourced Photographic Records to Explore Geographical Variation in Colour Polymorphism” Alex and I talked with Jules just before Christmas, about this paper, which concerns Lace Monitors, and we cover some other cool Australian herp stuff as well. Thanks for listening everyone! And as always, please keep the comments and suggestions coming, and please take time to rate the show on your podcast platform! The show email is somuchpingle@gmail.com, and there's also a So Much Pingle group on Facebook, for discussion, comments, feedback, suggestions, herp confessions, baby monitors to watch baby monitors, tips for herping better, etc. -Mike  

In the final episode of series three, hear Olly Belcher, President of the St Edmund Hall Association, in conversation with Professor Rob Whittaker, Teddy Hall's Vice Principal and Geography tutor. Rob was appointed as Vice Principal in 2019 and has been at Teddy Hall for 32 years where he has also been the College Dean and witnessed many changes including an expanding MCR and the increasing need to house all our students. Alongside the roles of Vice Principal and teaching Geography, Rob is a Professor of Biogeography and has spent much time researching island biodiversity. Rob sadly retires from Teddy Hall this year and his dream would be to see the Geography Fellowship endowed. Spirit of the Hall podcast is produced by the St Edmund Hall Association, the voluntary alumni body independent which represents all Aularians. The views and opinions expressed in the podcast are those of the speakers and do not necessarily reflect the official policy or position of the Association, St Edmund Hall or the University of Oxford.

This episode—which is Number 62—is all about the major geographic divisions among birds across the planet.Why are bowerbirds found only in Australia and on the islands of New Guinea? Why are the birds you see in India so different from those in China? Does North America have any unique, endemic bird families?Questions like these fall within the domain of biogeography. Biogeography is the study of where living things are found and why they're found there—both in the present and the past. Today, we'll be sketching out the big picture of what types of birds are found where across the world map.By learning the basics of bird biogeography, you can get a deeper appreciation for the uniqueness of bird communities in different parts of the world. ~~ Leave me a review using Podchaser ~~Links of InterestWhat Are The 7 Realms of Biogeography?

In this episode, Ben is joined once again by Dr Joseph Bailey, currently part of the team at YSJU Geography but soon-to-be Senior Lecturer in Ecology, Conservation and Sustainability at Anglia Ruskin University, to discuss the concept of ‘Geodiversity', and why the varied shape of the landscape is an important factor in determining ecosystem biodiversity, and its conservation. We discuss the ways in which Joe's research has explored this concept, and how he has sought to map and measure geodiversity through a holistic understanding of landscape processes. We reflect on how geographers are well-placed to offer insight into the significance of geodiversity, and how we might feed an understanding of geodiversity into conservation practice and policy. Below, for those who are interested, are some links to relevant readings that further flesh out the concepts / topics discussed... Key Reading #1: The 2022 article “Conserving Nature's Stage…” by John Gordon, Joe and Jonathan Larwood offers a useful account of the relationships between geo- and biodiversity, and the importance of preserving the varied surfaces of the earth upon which species flourish. Published in the Park Stewardship Forum and available online here as an open-access text: https://escholarship.org/uc/item/8fp8v4wk Key Reading #2: Joe's 2017 paper in Global Ecology and Biogeography, co-authored with several others and drawing on his PhD research, entitled “Modelling native and alien vascular plant species richness” specifically examines the question of scale, as discussed in the episode, and its importance when assessing the relevance of ‘geodiversity'. Published open access and available here: https://onlinelibrary.wiley.com/doi/10.1111/geb.12574 Further Reading: Joe and fellow researcher Franziska Schrodt wrote a really accessible article for the online news site The Conversation in 2019 that introduces the concept and importance of geodiversity for a non-specialist audience interested in conservation. Available online here: https://theconversation.com/our-new-research-is-tracing-the-development-of-the-worlds-vital-non-living-nature-125664 Further Reading: Joe recommends Murray Gray's 2013 book Geodiversity: Valuing and conserving abiotic nature as an excellent general reference text on the concept.

Today on Mushroom Hour we are host to the distinguished Dr. Kabir Peay – head of Stanford University's Peay Lab. Dr. Peay completed a master's degree at the Yale School of Forestry and Environment Science (F&ES) in 2003 and obtained a PhD in 2008 from UC Berkeley's Dept. of Environmental Science, Policy and Management (ESPM) in Matteo Garbelotto's lab. He completed postdoctoral training at UC Berkeley in the Dept. of Plant & Microbial Biology with Tom Bruns, and at Stanford in the Dept. of Biology with Tadashi Fukami. He was an Assistant Professor in the Dept. of Plant Pathology at the University of Minnesota from 2011-2012 before coming to Stanford in 2012 to join the Dept. of Biology in his current position. The Peay lab studies the ecological processes that structure natural communities and the links between community structure and the cycling of nutrients and energy through ecosystems - focusing on fungi! Much of the research focuses on plant-fungal root associations, better known as mycorrhizas, which constitute one of the most pervasive mutualisms in terrestrial ecosystems. By integrating their lines of research, they hope to weave together a 'roots-to-biomes' understanding of plant-microbe symbiosis.   TOPICS COVERED:   A Love of Nature, Inspiration in the East   From Environmental Consulting into Ecological Understanding   Discovering Fungal Symbioses   Defining Ecology & Community Assembly   Understanding Scale in Community Ecology    Embracing Fungi in All of Their Ecological Roles   Facultative Capacities of Fungi   Mycorrhizal Lessons in Community Ecology    Broadening Ecological Perspectives Beyond Purely Competitive Frameworks   MISSPs & Mediating Mycorrhizal Interactions   Fungal Biogeography   Ecological Succession & Stages of Community Assembly   Future of Mycorrhizal Research   Mapping Fungal Genes to Ecological Functions   EPISODE RESOURCES:   Peay Lab Academic Website: https://mykophile.stanford.edu/   Dr. Peay Google Scholar: https://scholar.google.com/citations?user=E6GRsP4AAAAJ&hl=en   Dipterocarpaceae - tree family: https://en.wikipedia.org/wiki/Dipterocarpaceae   Chytrids: https://en.wikipedia.org/wiki/Chytridiomycota   Pinus ponderosa (tree species): https://en.wikipedia.org/wiki/Pinus_ponderosa   Suilllus pungens (fungus species): https://en.wikipedia.org/wiki/Suillus_pungens    

Today on the Mushroom Hour we are honored to be joined by Dr. Andrew Wilson - Assistant Curator of Mycology in the Sam Mitchel Herbarium of Fungi at Denver Botanic Gardens. For Dr. Wilson the discovery of mycology began back in the late 90's at San Francisco State University in taking classes from world renown mushroom taxonomist, Dr. Dennis Desjardin. Working with Dennis, Andrew earned a Masters degree studying the mushroom genus Gymnopus from Java and Bali. He later went on to earn a PhD in the lab of Dr. David Hibbett at Clark University. His project took him back to Southeast Asia, this time to study the ecology and evolution enigmatic puffball genus Calostoma and their relatives. In 2009, Andrew graduated and began a postdoc with Dr. Gregory Mueller at the Chicago Botanic Garden where he explored the systematic evolution of the Cantharellales and the model ectomycorrhizal mushroom genus Laccaria. He also did a one-year postdoc at Purdue University, in the lab of Dr. Cathie Aime, teasing apart the complex evolution of plant pathogenic rust fungi. At Denver Botanic Gardens, Dr. Wilson is working on a regional contribution to the Fungal Diversity Survey (FunDiS) that encompasses the state of Colorado, with a focus on the Southern Rockies. In this effort he is training students on how to study biodiversity using natural history collection and DNA sequence analysis. He is also working on new tools in DNA sequencing to better sample and study fungal diversity.   TOPICS COVERED:   Formed in a Family of Biologists   Intellectual Explorations at San Francisco State University   Genus Gymnopus   Expeditions to Southeast Asia   What are Systematics?   Genus Calostoma   Role of Isotopes in Understanding Fungal Ecologies   Biogeographic Histories of Fungi   Interpreting Ancestry and Evolution in Phylogenetic Data    Gondwana Supercontinent   Finding a Living, Ancient Ancestor on the Lacarria Family Tree    Denver Botanic Gardens & Sam Mitchell Fungi Herbarium   New Methods of High-Throughput DNA Sequencing    Biodiversity & Evolutionary History of Southern Rocky Mountain Fungi   EPISODE RESOURCES:   Dr. Andrew Wilson - Denver Botanic Gardens: https://www.botanicgardens.org/team/profile/andrew-w-wilson-phd   Dr. Dennis Desjardin (Mentor): https://biology.sfsu.edu/faculty/desjardin   Dr. David Hibbet (Mentor): https://www2.clarku.edu/faculty/facultybio.cfm?id=355   Gymnopus (Genus): https://en.wikipedia.org/wiki/Gymnopus   Calostoma (Genus): https://en.wikipedia.org/wiki/Calostoma   Laccaria (Genus): https://en.wikipedia.org/wiki/Laccaria   Calostoma cinnabarinum: https://en.wikipedia.org/wiki/Calostoma_cinnabarinum   Colorado Mycological Society: https://cmsweb.org/   Colorado Mycoflora Project: https://coloradomycoflora.org/   

If you ever wanted to know anything about Denali, David Arnold is your man. He truly is a walking encyclopedia. He helped develop the nation's first - and at the time, only - broadcast meteorology program at Ball State University. With a Doctor of Philosophy (Ph.D.) in Atmospheric Science, Master of Science (M.S.) in Biogeography (macro-scale ecology), Bachelor of Science (B.S.) in Geography, Associate of Science (A.S.) in Architecture and Regional Planning, Dr. Dave can bring a wealth of information to a conversation about the natural forces at play in the magical place we call Denali.

Today on Mushroom Hour we are joined by illustrious lichen expert Matthew Nelsen PhD. Matthew is a Research Scientist at the Field Museum of Natural History in Chicago. Matt's research began in botany, ecology and environmental science and has more recently gravitated towards: (i) the evolution of symbiotic associations; and (ii) the evolution of eukaryotic microbes (fungi and algae), and the roles they have played in shaping terrestrial ecosystems and nutrient-cycling over geologic timescales. Both avenues of his research attempt to link diverse fields and organismal groups. He also has conducted work addressing the timing and evolutionary consequences of ant-plant interactions.

Today on Sojourner Truth's weekly Earth Watch segment our guest is Policy Director for the Center for Food Safety, Jaydee Hanson. Multinational corporations pushing GM crops, food, trees and fish are up against environmentalists who outright oppose them or question the need for them. Will we see a future where foods are derived from GM microorganisms or GM animals are more broadly introduced into the market? Does the general public even know what GM foods they are now consuming? In 2021, the U.S. District Court for the Northern District of California agreed, with the ruling that the FDA ignored the serious environmental consequences of approving GM salmon. The court also ruled that FDA's unilateral decision that GM salmon could have no possible effect on highly endangered, wild Atlantic salmon was wrong and it violated the Endangered Species Ac. The original suit was filed in 2016 by the Quinault Native American tribe in Washington state, who sued the FDA along with environmental and fishing organizations, for approving the safety of GM salmon based on limited research. We will speak to Policy Director for the Center for Food Safety, Jaydee Hanson on the recent court ruling and what it means for the future of GM foods in the U.S. Jaydee Hanson's expertise includes emerging technology issues related to nanotechnology, synthetic biology, animal cloning, animal genetic engineering and gene editing. He has a Master's degree in Biogeography and Resource Management from the University of Hawai'i. Before coming to the Center for Food Safety, he worked for the National Marine Fisheries Service, starting both the environmental justice program of the United Methodist Church and their genetics and bioethics program. He is a co-author of the Principles for the Oversight of Synthetic Biology, the US co-chair for the Nanotechnology Taskforce of the Transatlantic Consumers Dialogue, a member of the synthetic biology experts committee for the Convention on Biological Diversity and a fellow of the Institute on Biotechnology and the Human Future.

A look at different areas that pose a problem for the theory of universal common ancestry.

Paul and Casey Luskin consider scientific problems with the theory of universal common ancestry.

Casey touches on biogeogrphical data that does not easily fit with a theory of universal common ancestry.

Biogeography is often touted as indisputable evidence for evolution. Dr. Sarah Buckland, who obtained her PhD in Geography, makes the case that the evidence is actually stacked against the evolutionary theory, and in fact, the field of geography is a powerful testament to the Bible's authenticity. Did Pangaea exist? Does geographically distribution demonstrate common ancestry?

On this ID the Future, geologist Casey Luskin discusses biogeography and the problems it poses for the idea of universal common descent. To make it work, evolutionists have to propose, for instance, that old world monkeys rafted across the Atlantic from Africa to South America on a natural raft. Really? That's some raft. And how did the monkeys not starve to death? Or die of thirst? They couldn't drink salty ocean water, after all. And talk about a genetic bottleneck! That's just one of several problems Luskin raises with the idea that all species gradually evolved from a universal common ancestor. In his conversation with host Emily Reeves, he also touches on the problem of convergence, as when two creatures Read More › Source

Biogeography is the distribution of life within and around landforms. In a large deep canyon, that distribution is influenced by the elevation and the aspect of a slope which also controls the sunlight received. We talk with Larry Stevens of the Museum of Northern Arizona about his decades long investigation of biogeography within the Grand Canyon. More than 70% of the species found in the Grand Canyon are genetically affected by the landform itself and many can live nowhere else.

Dienas kļūst īsākas, gaisa temperatūra pazeminās un neatņemama rudens sastāvdaļa ir arī gājputnu kāši debesīs. Rudens migrācija var būt nostalģisks moments cilvēkiem, bet pašiem putniem tas ir nopietns pārbaudījums. Dažus šķēršļus putnu migrācijai rada arī cilvēks. Latvijas Ornitoloģijas biedrība ziņo, ka gājputnu migrācijas laikā liels apdraudējums ir stiklotā apbūve. Kādi cilvēka radītie šķēršļi Latvijā un citviet pasaulē apgrūtina gājputnu ceļu uz ziemošanas vietām, raidījumā Zināmais nezināmajā analizē ornitologi - Latvijas ornitoloģijas biedrības priekšsēdētājs Viesturs Ķerus un šīs biedrības projektu vadītājs Andris Dekants. Garākas kājas un knābji ļaus putniem pielāgoties klimata izmaiņām Zinātnieki uzskata, ka gan putnu, gan zīdītāju atsevišķu ķermeņa daļu – knābju, ausu vai astu palielināšanās ir saistīta ar dzīvnieku pielāgošanos klimata sasilšanai. Mainās ne tikai izskats, bet arī uzvedība: jau pirms pāris gadiem žurnālā „Global Ecology and Biogeography” bija raksts par starptautisku zinātnieku komandu, kuri izpētīja, kā siltumam pieaugot, mainās tārtiņu uzvedība olu perēšanas laikā. Ja parasti mātīte olas perē dienas laikā, bet otrs (lielākoties – tēviņš) to darīja nakts laikā, tad, analizējot putnu uzvedību vairākas tārtiņu populācijās, zinātnieki secināja, ka, pieaugot gaisa temperatūrai, pieaug tēviņu iesaiste olu perēšanā: tēviņš un mātīte olu perēšanas „maiņas” veic ievērojami biežāk, tādējādi saīsinot laiku, kas jāpavada tiešā saules iedarbībā. Vai tiešām tas, ka paaugstinās gaisa temperatūra uz planētas, ietekmē putnu izskatu un uzvedību, jautājam Latvijas Universitātes asociētajam profesoram un Daugavpils Universitātes vadošajam pētniekam Indriķim Kramam, lai noskaidrotu, kā un vai klimats ietekmē putnu adaptāciju.

My AP Biology ThoughtsEpisode #13Welcome to My AP Biology Thoughts podcast, my name is Chloe and I am your host for episode 13 called Unit 7 Evolution: Adaptive Radiation in Darwin's Finches. Today we will be discussing the diversification of the mainland species of finches due to adaptive radiation.  Segment 1: Introduction to Adaptive Radiation in Darwin's FinchesIt's important to understand what this all means. Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a variety of new forms. A change in environment can introduce a species to new available resources, and can open new environmental niches. These openings cause new competition within the species, eventually leading to a certain trait being more advantageous.  This ties in perfectly with the natural selection mechanism which describes the relationship between overpopulation, variation, competition, fitness, reproduction . The widespread of niches on the Galapagos makes a perfect fit for this mechanism to take place, and for rapid speciation to occur.  This brings us right to the important stuff, the finches. The theory is that a  small population of mainland finches migrated to each of these islands with different niches, creating competition for a certain type of resource.  Variation caused one particular trait to be  more beneficial than others, causing rapid speciating among these populations  Segment 2: Example of Adaptive Radiation in Darwin's FinchesThe finches varied in beak sizes and fur color.  Larger beaks were beneficial in niches where the available food source mostly consisted of  large, difficult to open nuts while Smaller and thinner beaks were beneficial where the main source of food was insects because their small beak  made it easier to prey on small bugs. This made it easy for competition to take its route, and let the finch that is more fit for the specific food source to survive and reproduce.  Segment 3:Digging Deeper into Adaptive Radiation in Darwin's FinchesTo dig in deeper, it's important to realize how this information is still relevant. This observation that Darwin made gave him evidence for his theory of natural selection that we still use today. The natural selection mechanism that we study still continues to cause organisms to evolve and speciate. Another important concept to this specific example of adaptive radiation is the divergent evolution that occurred, and how each population became a new species due to the available resources. Biogeography also helped Darwin understand the relatedness of the finches on different islands because their closeness in geography helped prove that they were related in some way Thank you for listening to this episode of My AP Biology Thoughts.

My AP Biology Thoughts Episode 7 Welcome to My AP Biology Thoughts podcast, my name is Victoria and I am your host for episode #7 called Unit 7 Evolution: Evidence of Evolution. Today we will be defining the 4 Pieces of Evidence for Evolution, giving examples of each, and making connections to the unit of evolution.  Segment 1: Introduction to Evidence of EvolutionWhat is evolution? A change in the allelic frequencies of a gene pool  Continuous  4 Pieces of Evidence of Evolution -  Fossil Record the preserved remains of traces of any organisms from the remote past, included both discovered and undiscovered Only the hard parts of an organism are preserved  Fossil evidence can be either  Direct (body fossils): bones, teeth shells, leaves Indirect (trace fossils): footprints, tooth marks, tracks, burrows Like timeline, different kinds of organisms do not occur randomly but are found in rocks in a consistent order, this is known as the law of fossil succession  It is incomplete, and requires an unusual combination of specific circumstances for it to occur, creating many gaps in the fossil record  Biogeography: Organisms located in one area of the planet are closely related than those found in other parts of the planet It describes the distribution of organisms, over geographical areas, both in the past and present Comparative Anatomy: The comparison of the anatomic features of different species 2 Key types of structures that support this Homologous structures Demonstrate a similar underlying anatomy due to shared evolutionary origin, but have evolved into a variety of distinct forms or speciation due to the presence of different selective pressures The more similar the homologous structures between the two species are, the more closely related they are likely to be Adaptive radiation through divergent evolution, as similar basic organisms have been adapted to suit various environmental niches  Analogous structures  Adaptations that have similar features and functions as a result of exposure to a common selective pressure, but have different underlying anatomies due to having unrelated evolutionary origins  Shows convergent evolution as unrelated species have become structurally more alike due to exposure to shared selection pressures  Vestigial organs Homologous features that still remain in organisms, but serve no function or purpose in that organism but were once present and functional in their ancestors Changes in the environment have caused these organs to be useless and as a result over they have lost their functionality, they show the evolutionary divergence of a species from a past behavior/activity  Comparative embryology Studying the growing embryo in animals and plants show that closely related organisms go through similar stages of development Molecular Evidence: Identifying conservation in DNA and protein sequences as a basis for determining evolutionary relationships, the comparison of DNA sequences can show how different species are related Segment 2: Example of Evidence of EvolutionEvolution of the modern day horse (fossil record) Distribution of marsupials around the earth (biogeography) Biogeography the distribution of species around the world. It all started with a supercontinent called Pangaea. Over millions of years, Pangaea drifted apart into separate continents in a phenomenon called continental drift. Different species were separated on different continents. In particular, a majority of the marsupial population stayed on the continent known as Australia. Here's how it went… The blue line illustrates the distribution of marsupials around the world. The highest concentration today is in Australia. The marsupial species that migrated there was free to breed, causing their populations to proliferate and diverge into new species. However, the marsupials on the rest of the planet could not...

The problem with modern politics is that it excludes nature in its planning. Then, nature imposes her will—as she is doing now with the COVID-19 outbreak. What is the message and the learning in the emergence of the virus at this time? The spiritual elders of Colombia, the Mamos, are some of the few people who address the underlying causes to today's crisis. What does the virus mean not just in terms of the survival of the human species, but for all of nature? Mamo Daiwiku will be joined by Dr. Amanda Bernal-Carlo, a biologist who works closely with the Mamos, and Susan Kaiulani Stanton (Haudenosaunee/Native Hawaiian), founder of Grandmothers Circle the Earth Foundation, for an enlightening big picture overview. Glenn Aparicio Parry, PhD, of Basque, Aragon Spanish, and Jewish descent, is the author of Original Politics: Making America Sacred Again (SelectBooks, 2020) and the Nautilus award-winning Original Thinking: A Radical Revisioning of Time, Humanity, and Nature (North Atlantic Books, 2015). Parry is an educator, ecopsychologist, and political philosopher whose passion is to reform thinking and society into a coherent, cohesive, whole. The founder and past president of the SEED Institute, Parry is currently the director of a grass-roots think tank, the Circle for Original Thinking and is debuting this podcast series of the same name in conjunction with Ecology Prime. He has lived in northern New Mexico since 1994. www.originalpolitics.us Mamo Daiwiku is a Colombian Arhuaco Mamo (one of the spiritual elders) from the High Sierra Nevada de Santa Marta mountains, the tallest coastal mountain range in the world, source of 35 major rivers and over 200 tributaries, considered the Heart of the World by the Arhuaco, Kogi, Wiwa, and Kankuamo Indigenous peoples who live there.   Amanda Bernal-Carlo is originally from Colombia where for several years she studied the ecology of the Andean Forest and the Paramos. She is a scholar of Biogeography, Ecology and Medicinal Plants, and the President of The Great Balance. In 1989, while carrying out research on the biogeography of the Sierra Nevada de Santa Marta, Colombia, she became involved in the study of the Kogi Indians, their philosophy of life, and their traditional healing. For several years she collaborated with the Fundacion Pro-Sierra, an NGO supporting these Indigenous communities. In 1996, she received the First National Research Prize from the Colombian government for the work she accomplished on the Colombian Andean Mountains. Susan Kaiulani Stanton (Mohawk/Native Hawaiian) is the Founder and Senior Grandmother of Grandmothers Circle the Earth Foundation, an international organization that travels the world in service of Mother Earth and future generations, giving birth to new Grandmother councils all over the planet. Susan is Vice-President of the Great Balance, bi-located in the United States and Colombia with a focus on building a culturally appropriate university and the planting of one million trees to protect and perpetuate the culture and sacred land of the mamos, the Indigenous People of the beautiful Sierra Nevadas de Santa Marta. She is a delegate with the International Public Policy Institute to the United Nations Commission on the Status of Women.
