Podcasts about Tiktaalik

One of the best parts of hosting the Origins podcast is talking with remarkable scientists whose ideas have changed the way we understand ourselves and our world. My recent conversation with Neil Shubin was particularly enjoyable, not only because Neil is a friend whose insights I admire, but because our dialogue ranged across some of the most fascinating questions at the intersection of evolution, exploration, and human curiosity.Neil became widely known for discovering Tiktaalik, the fossil fish whose fins contain bones remarkably similar to the limbs of land animals, including us. He is currently the Robert R. Bensley Distinguished Service Professor of Organismal Biology and Anatomy at the University of Chicago and the bestselling author of Your Inner Fish and, most recently, The Ends of the Earth. But beyond his credentials, Neil embodies the careful, patient, and humble approach to discovery that value in science.Our discussion began with the unexpected paths scientists take, including Neil's own formative experiences. He described how museum visits and planetarium shows ignited his childhood fascination, and we talked about how a single course on vertebrate evolution at Harvard redirected his career from veterinary medicine to fossil hunting. Neil recounted, and we discussed at length, the meticulous thought and considerable risk that led him and his colleague, Ted Daeschler, to choose the Canadian Arctic for their famous expedition. It took six summers of tough fieldwork before their gamble yielded Tiktaalik, transforming our understanding of how life transitioned from water to land.But our conversation wasn't just about past discoveries. Neil and I explored broader themes about the nature of science itself: how hypotheses are formed, the patience and courage it takes to test bold ideas, and the critical importance of embracing failure. We agreed that stepping outside one's comfort zone is almost always necessary to achieve scientific breakthroughs, and Neil shared how his own career exemplifies precisely that.This kind of deeper dialogue, going beyond the headlines to explore the very human stories behind scientific discoveries, is one of the reasons I started the Origins podcast. I hope you find this conversation with Neil Shubin as enjoyable and thought-provoking as I did.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

By the end of the Devonian Period, the land had exploded with plant life and ancient invertebrates. There was also Tiktaalik - one of the first known vertebrates able and willing to move from the water to land. Our distant relative figured out how to survive in this dramatically different environment, can you? --Eons is a production of Complexly for PBS Digital Studios.If you'd like to support the show, head over to Patreon and pledge for some cool rewards!Want to follow Eons elsewhere on the internet?FacebookYouTubeTwitterInstagram

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.

RVG - "Squid" from the 2023 album Brain Worms from Fire Records Travel back in time with Melbourne-quartet RVG on today's Song of the Day.  “'Squid' is a song about going back in time and stepping on a Tiktaalik and then going back to the present but you have the same job, the same problems you had before except you're a squid,” vocalist Romy Vager explained to Rolling Stone Australia. “We jammed it on a whim and it ended up coming out really well. I left a large chunk of the lyrics till the last minute, finishing them off in Finsbury Park at 6 in the morning before I could get into the studio and record my vocals.” The track can be found on the band's third LP, Brain Worms, released last month via Fire Records. The band says the new album captures them at their most confident yet. “Hype is scary. After two years of COVID, it felt like the hype had gone down so we were able to just do stuff,” says Vager in a press statement. “This time around we were like, this is what we're doing, we're taking control, we're taking risks, and we're going to make an album that sounds big so that when we hear it on the radio we want to hear it again.”  Read the full story at KEXP.orgSupport the show: https://www.kexp.org/donateSee omnystudio.com/listener for privacy information.

(image source: https://en.wikipedia.org/wiki/Tiktaalik by Zina Deretsky) Host Matthew Donald and guest co-host Christina Eilert discuss Tiktaalik, a real asshole that should have known what horrible things crawling onto land would eventually lead to for the world. From the Late Devonian, this 8-foot sarcopterygian has been the subject of many memes using this very image about how it's personally responsible for all of human suffering, which in all honesty might just be a tad harsh.

In this episode, Xavier Bonilla has a dialogue with Neil Shubin about the building blocks of life over billions of years. They discuss why the fossil record is so essential for understanding the history of the earth and for understanding the history of past and present organisms. They talk about the importance of the discovery of Tiktaalik. They also talk about the four arches that make up all heads within embryology along with the continuity that is seen with eyes and ears. They discuss Darwin's concept of "by a change of function," and the importance of embryonic comparison. They have a discussion on how DNA and genes are important for change of function, the sonic hedgehog gene, and the future of the human body.  Neil Shubin is a Paleontologist and Evolutionary Biologist. He is the Robert Bensley Distinguished Service Professor at the University of Chicago and the Associate Dean for academic strategy of the Biological Sciences Division. His research focuses on the evolution of new organs and he and his team discovered the 375 million-year-old Tiktaalik fossil. He is the author of three popular science books: Your Inner Fish: A Journey Into the 3.5 Billion-Year History of the Human Body, The Universe Within: The Deep History of the Human Body, and Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA.

The gang discusses two papers that explore the functional morphology of ancient groups. The first paper looks at soft tissue in ammonites which can be used to infer locomotion, and the second paper looks at how functional morphology changed as tetrapods transitioned from marine to terrestrial environments. Meanwhile, James explores the evolution of baked goods, Curt develops a new business plan, and Amanda dreams of Tiktaalik.   Up-Goer Five (Curt Edition): Our friends talk about two papers that look into how we can learn how very old animals moved and how that moving changes over time by looking at the parts we can find in the ground. The first paper looks at animals with a lot of arms who live in a big hard round hard part. Today, while we have a lot of these animals with lots of arms, only one of those animals today lives in a big round thing. In the past, there was a big group of animals that lived in a round thing, but they did it in a different way than the one we have around today. However, because it is hard to find pieces that are not hard, we have used the animal that is around today as our best guess for how these old animals may have moved. This paper finds some soft pieces which give us a better idea of how the soft parts that allow animals to move were put together. And these old animals probably moved in a very different way from the other animal from today who lives in a round thing. In fact, the old animals that live in round parts may have moved in a way that is sort of like how the animals with many arms who do not live in round things today move (but not exactly the same). The second paper looks at how the hard parts of animals with four legs changed when they animals moved onto land. This paper looks at these changes and also looks at how these changes make it so these animals move in different ways. They find that the animals with four legs in the water all have legs that look like we would expect for moving in water. The animals that are on land also have legs that fit the moving we would see for things that need to hold themselves up and move on land. The fun thing is that the animals who come from the animals who are not quite on land and not quite in water yet (the ones in the middle of this change) do not fit into any space where we would expect the animal to be able to move well. This could mean that these animals (which did well enough) were living in a time when it was alright to suck at moving. Also, it may be that some groups of animals that moved onto land from this group that sucks at moving might have had some of the animals in that group that came back to this sucking at moving space.   References: Dickson, Blake V., et al.

Mudsharks! Depending where you live, these bottom-dwelling, single-whiskered fish are also known as burbot, ling, eelpout, cusk, and, in the Kobuk area of Alaska, "Tiktaalik" (the list goes on). Katrina and Guy talk with guest Raymond Woods, Iñupiaq Program Coordinator for the Northwest Arctic Borough School District, about traditional under-ice trapping techniques for this amazing, important fish. 

Dr. Neil Shubin, Harvard GSAS Class of 1987, is a paleontologist, evolutionary biologist, and popular science writer. Dr. Shubin made headlines in 2004 when he co-discovered Tiktaalik roseae, a fossil of a creature with traits found in both fish and tetrapods, and has since published three popular science books: Your Inner Fish, The Universe Within, and Some Assembly Required. In today's conversation, Gemma and Dr. Shubin unpack how Dr. Shubin's time-tested affinity for exploration ultimately manifested into a career that involves traveling to places as far-away and frigid as the Canadian Arctic. They also discuss the importance of challenge and failure – in both science and writing – before exploring how Dr. Shubin's landmark discovery of Tiktaalik dramatically altered the trajectory of his personal and professional life. Finally, at the end of this episode, contributing commentator Mable Chan (Harvard AM '93), will offer a commentary about the things that cannot be taught – in college or beyond – and which you must find on your own.

How far will you travel outside of your hometown, your neighborhood, your comfort zone, in order to see the world differently? Why is it important to keep your sense of insecurity as your companion as you embark on your scientific, academic or philosophical enquiry? How does failure keep you hungry for success? Those are some of the questions that have led to surprising discoveries and satisfying rewards for Dr. Neil Shubin (Harvard GSAS Class of 1987). In “Where Are They Now?” Episode #4, Gemma Schneider (Harvard student journalist/Class of 2023) interviews Dr. Neil Shubin - A paleontologist, evolutionary biologist, and popular science writer.  Dr. Shubin made headlines in 2004 when he co-discovered Tiktaalik roseae, a fossil of a creature with traits found in both fish and tetrapods, and has since published three popular science books: Your Inner Fish, The Universe Within, and Some Assembly Required. I am happy to be co-hosting this podcast as a contributing commentator. You'll hear my reflection on how I, like Dr. Neil Shubin, first became drawn to a new world of possibilities that would light up my imagination to pursue a path that's formed who I am today. ———————— “Where Are They Now?” is a special co-production between One in a Billion and WHRB (Harvard Radio Broadcasting). It is a 6-part series featuring one-on-one interviews with Harvard graduates who draw lessons from their campus experience and personal insight from their current career to give you a taste of their trailblazing journey. “Where Are They Now” is sponsored exclusively by One in a Billion Productions Inc.

In the late 1930s, our understanding of the transition of fish to tetrapods — and the eventual jump to modern vertebrates — took an unexpected leap forward. The evolutionary a'ha came from a single partial fossil skull found on the shores of a riverbank in Eastern Canada. Meet the Stegocephalian, Elpistostege watsoni, an extinct genus of finned tetrapodomorphs that lived during the Late Givetian to Early Frasnian of the Late Devonian — 382 million years ago. Elpistostege watsoni — perhaps the sister taxon of all other tetrapods — was first described in 1938 by British palaeontologist and elected Fellow of the Royal Society of London, Thomas Stanley Westoll.  Westoll's research interests were wide-ranging. He was a vertebrate palaeontologist and geologist best known for his innovative work on Palaeozoic fishes and their relationships with tetrapods. As a specialist in early fish, Westoll was asked to interpret a single partial skull roof discovered at the Escuminac Formation in Quebec, Canada. His findings gave us the publication that would name Elpistostege watsoni and helped us to better understand the evolution of fishes to tetrapods — four-limbed vertebrates — one of the most important transformations in vertebrate evolution. Hypotheses of tetrapod origins rely heavily on the anatomy of a few tetrapod-like fish fossils from the Middle and Late Devonian, 393–359 million years ago. These taxa — known as elpistostegalians — include Panderichthys, Elpistostege and Tiktaalik — none of which has yet revealed the complete skeletal anatomy of the pectoral fin. None until 2010, that is when a complete 1.57-metre-long articulated specimen was described by Richard Cloutier et al. in 2020. The specimen helped us to understand the origin of the vertebrate hand. It revealed a set of paired fins of Elpistostege containing bones homologous to the phalanges (finger bones) of modern tetrapods and is the most basal tetrapodomorph known to possess them. Once the phalanges were uncovered, prep work began on the fins. The fins were covered in scales and lepidotrichia (fin rays). The work was tiresome, taking more than 2,700 hours of preparation but the results were thrilling. We could now clearly see that the skeleton of the pectoral fin has four proximodistal rows of radials — two of which include branched carpals — as well as two distal rows organized as digits and putative digits. Despite this skeletal pattern — which represents the most tetrapod-like arrangement of bones found in a pectoral fin to date blurring the line between fish and land vertebrates — the fin retains lepidotrichia (those wee fin rays) distal to the radials. This arrangement confirmed an age-old question — showing us for the first time that the origin of phalanges preceded the loss of fin rays, not the other way around. This was evidence for the origins of the vertebrate hand that you and I use today.

How did fish evolve to walk on land? What are the details of how that process happened? Today on The Soul of Life I speak with Neil Shubin, the 2004 co-discoverer of Tiktaalik, a fish fossil that is the first evidence of so-called bridge animals with features that show the evolutionary transition between swimming fish and land mammals. Shubin is the author of Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body and Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA. Neil guides us through a fascinating tour of the history of the human body. We talk about the remarkable building blocks inside DNA that are common to all living things, which is the topic of Shubin's latest book Some Assembly Required.

Hace ya doce años empezamos este programa de Zoo de fósiles hablando de Acanthostega, el pez de ocho dedos. Acanthostega, que vivió hace unos 365 millones de años, está cerca del antepasado de todos los vertebrados terrestres, aunque él mismo era un animal acuático, sus patas eran incapaces de sostenerlo fuera del agua. Esto no quiere decir que no hubiera otros vertebrados terrestres en esa época, o incluso antes; seguramente Acanthostega descendía de un linaje de especies terrestres que volvieron prematuramente al agua. Nuestro protagonista de hoy, Tiktaalik, era capaz de arrastrarse por tierra firme como una foca, y es más antiguo que Acanthostega: Vivió en lo que hoy es la isla de Ellesmere hace unos 375 millones de años, a finales del Devónico.

Fish with legs? Crazy, right? Turns out, fish with legs are a lot more real than you might think! We teamed up with What If World, one of our favorite storytelling podcasts, to answer this question both scientifically and creatively! In our “science version,” we consult with the funniest fish biologist you’ll ever meet, Solomon David. He’s obsessed with creating puns for gars, the prehistoric fish that he studies. And he explains why fish are the reason that we have legs! Plus, you’ll meet fish that can “walk” on land. It’s nuts. On April 5 - three days after this episode is released - you’ll want to tune into fellow kidcast What If World to hear Marshall and Lindsay guest-star in a story about their pet gar who grows legs and puts them in a tank! It’s the “creative version” of the story, and What If World’s 200th episode! Wait, want more science? Listen to the bonus interview episode with Solomon David, when you support Tumble at the $1 level or higher on Patreon. You’ll also get an ad-free feed!

Neil Shubin reveals how he discovered Tiktaalik — a long-sought fossil link between swimming fish and walking land animals — and shares other remarkable tales about life's evolution. See omnystudio.com/listener for privacy information.

One of the great themes in palaeobiology is the water-land transition, or how and when the ancestors of today’s four-legged terrestrial animals moved to land. Lines of questioning have included understanding the anatomy and biomechanics of the axial skeleton- head and vertebrae (focusing on biting and swallowing) and the appendicular skeleton (focusing on how the earliest tetrapods walked or swam). Our picture of this story has drastically changed in the last three decades, as new fossils have filled in crucial gaps in the tetrapod evolutionary tree. This changing picture really came to the fore with the work of the late Professor Jenny clack, who’s work at Cambridge in early tetrapods from Greenland and elsewhere  brought the water land question back in fashion.  Joining us to discuss Jenny Clack's Legacy in this episode are Prof. Mike Coates and Ben Otoo both of the University of Chicago. 

Evidence for evolution from many fields has been thoroughly refuted but continues to be taught. We summarize key refutations from areas including: Vestigial organs, Junk DNA, Humans and chimp DNA 99% similar, Homology, Human embryos go through evolutionary stages, Transitional fossils, Pakicetus, Tiktaalik, Ape-men, Human evolution, Radiometric dating, Distant starlight.

Early tetrapods include the earliest animals to grow legs, and their closest ancestors. Moving from the water to land required a number of changes within the skeleton and muscular system, related to moving from swimming to crawling, greater pressure on the body after experiencing further effects of gravity without buoyancy, and the difference in feeding with and without water. This transition is commonly referred to as the 'water-to-land' transition. While a significant amount of work has been done on the anatomical changes through this period, there has been less study on the biomechanics. What has been looked at tends to relate to the mechanical changes related to walking on land and the limbs. However, less has been done looking at the skull mechanics and feeding. Early tetrapod work was pioneered by Professor Jenny Clack. She did a lot of early field work and description, understanding this transition better than anyone. Sadly, Professor Clack passed away in March, but has left behind a legacy of other professors, post docs and students around the globe which she inspired. In this episode, we talk to Dr Laura Porro from University College London about her work on early tetrapod feeding and skull mechanics, and how the skull changed over the water-to-land transition, work which was done with and inspired by Jenny.

In this episode exploring great ideas in genetics, we’re discovering our inner fish - finding out whether we really do go through a fishy phase in the womb, and looking at the legacy of Tiktaalik, the first fish to walk on land.Born in 1834, Ernst Haeckel was a German zoologist with a flair for illustration - and a knack for creating incredibly detailed and widely shared scientific images. But do his infamous embryo drawings really show the true picture of early development?Haeckel thought that we went through a 'fish' stage in the womb because our embryos appear to have gills during early development. Although his theory that 'ontogeny recapitulates phylogeny' has subsequently been shown to be incorrect, we now know there is a close connection between development and evolution, or 'evo-devo' as it's sometimes known.In short, our evolutionary history is written in our developmental genes, and it’s a history that we can trace right the way back to the very first vertebrates. The best example of this is Tiktaalik - our oldest 'fishapod' ancestor that forms the missing link between fish and land-dwelling tetrapods.Full show notes, transcript, music credits and references online at GeneticsUnzipped.comFollow us on Twitter @GeneticsUnzipGenetics Unzipped is written and presented by Kat Arney, and produced by First Create the Media for the Genetics Society - one of the oldest learned societies in the world dedicated to supporting and promoting the research, teaching and application of genetics.

Lang geleden kroop de Tiktaalik roseae als eerste waterdier het land op. Althans, dat is het vermoeden - zeker weten doen we het niet. Wat we wel zeker weten, is dat dit inmiddels uitgestorven chordadier niet zal hebben doorgehad dat hij 375 miljoen jaar later in de inleiding van een wetenschapspodcast over evolutie zou genoemd. Daar was-ie vast hartstikke trots op geweest.Want daar gaan we het over hebben deze aflevering: evolutie en genetica! Wat een feest! En dat doen we met niemand minder dan dr.

We're taking a summer break during July, but we'll be back in August with new episodes telling the stories of leading research with some of the world's greatest minds. During the break, we'll be bringing you updated versions of prior episodes. Evolutionary biologist Neil Shubin spent six years in the Arctic searching for a fossil that could be a missing link between sea and land animals. Shubin shares the story behind his discovery of Tiktaalik, what it has meant for the understanding of human evolution, and how it has impacted the future of genetic research.

Neil Shubin researches the evolutionary origin of anatomical features. Dr. Shubin's most recent discovery, Tiktaalik roseae, has been dubbed the "missing link" between fish and land animals. Dr. Shubin discusses Tiktaalik and the evolutionary shift from life in water to life on land.

One of palaeontology‘s great themes of questioning is the rise of novelty: how new structures and functions arise in specific lineages. In this episode we speak with Neil Shubin, Professor of Organismal Biology at the University of Chicago, who has been studying novelty in the context of the vertebrate transition from water to land. Neil studies the fossil record of early tetrapods, the first vertebrates with limbs, to understand what changes underpinned this great transition. The other half his lab uses molecular techniques on living organisms to see how changes to the development of appendages (and their underlying genetic architecture) effected the shift from a fin to a limb. In this interview, we hear about his fieldwork in the Arctic and Antarctic, how palaeontologists decide where to look for key fossils, why development matters, and about his deep involvement in science communication.

Bom, sei que deve estar todo mundo estufado de ter comido uns peixes ontem e agora só esperando a hora de comer os chocolates amanhã. Porém, vocês já se perguntaram como que os animais conseguiram conquistar o ambiente terrestre? Bom, mas o que os Peixes tem a ver com isso tudo? Bom, Tiktaalik é um gênero de peixes sarcopterígeos (que possuem nadadeiras com músculos) extinto no período Devoniano (375 milhões de anos) e com muitas características típicas de tetrápodes. Contamos a vocês que os primeiros organismos a conquistarem o ambiente terrestre foram as plantas, no último episódio. Porém, logo em seguida tivemos os animais conquistando também esse ambiente, e se diversificando em inúmeras linhagens. Nesse episódio convidamos nosso amigo Eder França para discutir como isso ocorreu, e quais foram os desafios que foram necessários serem superados para que os animais pudessem colonizar o ambiente terrestre.

Evolutionary biologist Neil Shubin spent six years in the Arctic searching for a fossil that could be a missing link between sea and land animals. In 2004, Shubin discovered Tiktaalik roseae, a 375-million-year old creature that was part fish, part land-living animal. On this episode of Big Brains, Shubin shares the story behind his discovery of Tiktaalik, what it has meant for the understanding of human evolution, and how it has impacted the future of genetic research.

The transition of fins to limbs is one of the most significant in the history of vertebrate evolution. These were the first steps that would eventually allow tetrapods to go on to dominate so many terrestrial ecosystems. Fossils that help fill the gaps in this crucial time are invaluable, so how do we go about finding them and what happens when we do discover one? Joining us to give an overview of some of the fossils involved in this transition, and to provide insights into the fieldwork that goes into finding them, is Dr Ted Daeschler, Academy of Natural Sciences of Drexel University.

In this episode, we discuss two papers about early tetrapods/tetrapodomorph taxa, Tiktaalik  and Ichthyostega, and what new findings suggest about their locomotion. Also, Curt makes a suspicious delivery, and James desperately tries to feed Amanda "spoilers" for the new Star Wars. EDITOR'S NOTE: While I cannot confirm that any of James's spoilers are indeed accurate, they seem highly unlikely to be true (although if they are true, then the film they suggest is AMAZING). Up goer five simple text summary: The group takes time out from a time when not much is meant to happen to talk about some animals with big arms that were some of the first animals with four legs to come on to land. In between talking about a space movie where people use guns that fire light to show how they feel about each other, the group looks at a paper looking at the back end of an animal that had before been known only from its front. This new part of the animal shows that it had very small back legs that still looked more like for use in water. The second paper looks at a well known animal with four legs in a new way for the first time. It uses computers to picture it in a way that you can't picture it with just eyes, and this shows new things about it. The new way of looking shows that the animal would not have been as good at walking on land as people have thought. This is important as there are tracks that show there were animals with four legs that were very good at walking on land around at the same time. The animals that we have found were not able to make these tracks, and so this shows that there were other animals around at the same time that were better at walking on land, and that maybe this group of animals that walked on land started earlier than we thought.

One fateful February evening in 2013 the scientist and revered personality Bill Nye traveled to Kentucky to debate Ken Ham, the CEO and founder of Answers in Genesis, on the viability of The Creation Theory. That was one year ago. As you'll learn in this episode, this debate was instrumental in the founding of this podcast. Anthony and Chad have wanted to discuss and breakdown this debate for a long time. This episode is the culmination of tons of research and work about Creation and this debate specifically.

We all know the Darwin fish, the clever car-bumper parody of the Christian "ichthys" symbol, or Jesus fish. Unlike the Christian symbol, the Darwin fish has, you know, legs. Har har.But the Darwin fish isn't merely a clever joke; in effect, it contains a testable scientific prediction. If evolution is true, and if life on Earth originated in the oceans, then there must have once been fish species possessing primitive limbs, which enabled them to spend some part of their lives on land. And these species, in turn, must be the ancestors of four-limbed, land-living vertebrates like us.Sure enough, in 2006, scientists found one of those transitional species: Tiktaalik roseae, a 375 million-year-old Devonian period specimen discovered in the Canadian Arctic by paleontologist Neil Shubin and his colleagues. Tiktaalik, explains Shubin this week’s episode, is an "anatomical mix between fish and a land-living animal.""It has a neck," says Shubin, a professor at the University of Chicago. "No fish has a neck. And you know what? When you look inside the fin, and you take off those fin rays, you find an upper arm bone, a forearm, and a wrist." Tiktaalik, Shubin has observed, was a fish capable of doing a push-up. It had both lungs and gills. It's quite the missing link.On the show this week, we talk to Shubin about Tiktaalik, his bestselling book about the discovery, Your Inner Fish: A Journey Into the 3.5 Billion Year History of the Human Body, and the recently premiered three-part PBS series adaptation of the book, featuring Shubin as host who romps from Pennsylvania roadsides to the melting Arctic in search of fossils that elucidate the natural history of our own anatomy.This episode also features a discussion of the growing possibility of an El Nino developing later this year, and the bizarre viral myth about animals fleeing Yellowstone Park because of an impending supervolcano eruption.iTunes: itunes.apple.com/us/podcast/inquiring-minds/id711675943RSS: feeds.feedburner.com/inquiring-mindsStitcher: stitcher.com/podcast/inquiring-minds

"We are all star stuff." After discussing FFRF legal complaints in South Dakota and Arkansas, we take up on Carl Sagan's famous words by talking with paleontologist Neil Shubin, discoverer of Tiktaalik and author of the bestselling Your Inner Fish, whose newest book is The Universe Within: Discovering the Common History of Rocks, Planets, and People.

Neil Shubin researches the evolutionary origin of anatomical features. Dr. Shubin's most recent discovery, Tiktaalik roseae, has been dubbed the "missing link" between fish and land animals. Dr. Shubin discusses Tiktaalik and the evolutionary shift from life in water to life on land.

As most readers of this blog probably know, I cross-post these mixes over at Mixcloud.  Recently I got a request from listener, TikTaalik.  This is part of his post, "I was wondering if you could compile a mix that is optimistic throughout. The sort of ambience that I tend only to hear once or twice in a set. Can you get a solid hour of calm ambient music with a euphoric undertone?" At Low Light Mixes we give the people what they want, so here it is...Positively Ambient.  I'm not sure if all of the music qualifies as "optimistic" or "euphoric" but it is all calm & beautiful.  I start things off with Eno's "An Ending(ascent)" because I think it's one of the most beautiful pieces of music ever written.  Although it may work better as "an ending" than as a beginning, I wanted it up front so everyone that plays the mix is guaranteed to hear it. I hope the rest of the mix doesn't get too sweet or too pretty sounding.  I don't want it to dissolve into new age crapola.  I dug into the archives for some of the tunes like James Johnson's "Entering Twilight" from 2000, Jim Cole from 2002, Diatonis from 2003, Fox & Budd from 2003, Jeff Pearce from 1999 and Stephen Bacchus from 1998. The feel of this mix is definitely soothing, no dissonant chords to be found.  It works well as sleep music, meditation music, , etc.  Just good 'ole traditional ambient music.

University of Chicago fossil preparator, Tyler Keillor, discusses the iterative process of creating the model for Tiktaalik, the fossil discovery by paleontologist Neil Shubin that fills in the evolutionary gap between fish and land animals.

Paleontologist Neil Shubin describes how scientists are reconstructing the history of life from fossils and DNA, how genes shape bodies and what we have in common with fruit flies.

Neil Shubin is a distinguished paleontologist whose research seeks to understand the mechanics behind the evolutionary origin of anatomical features of animals. His work focuses mainly on the Devonian and Triassic periods to understand the pivotal ecological and evolutionary shifts that occurred during that time. In 2004, after scouring the Canadian Artic for six years, Shubin and his team unearthed the Tiktaalik roseae, a fossil “fishapod,” which, despite its fish-like features, had a neck, skull, ribs, and parts of limbs similar to land animals. This discovery represents the transition between fish and four-legged mammals that occurred over 350 million years ago.  Hitchcock Lecture description: Evolutionary biology is a science that allows us to make predictions, about fossils in the geological record and the activity of different genes in different kinds of creatures.  In his first lecture, Professor Shubin will discuss how this type of approach helps us to understand some of the great transformations in the history of life.  His second lecture will ask the question “How do new organs arise in the history of life?” New technologies allow us to look at this and other classic questions in biology.
