The author of the best-selling Your Inner Fish gives us a lively and accessible account of the great transformations in the history of life on Earth - a new view of the evolution of human and animal life that explains how the incredible diversity of life on our planet came to be. Over billions of years, ancient fish evolved to walk on land, reptiles transformed into birds that fly, and apelike primates evolved into humans that walk on two legs, talk, and write. For more than a century, paleontologists have traveled the globe to find fossils that show how such changes have happened. We have now arrived at a remarkable moment - prehistoric fossils coupled with new DNA technology have given us the tools to answer some of the basic questions of our existence: How do big changes in evolution happen? Is our presence on Earth the product of mere chance? This new science reveals a multibillion-year evolutionary history filled with twists and turns, trial and error, accident and invention. In Some Assembly Required, Neil Shubin takes readers on a journey of discovery spanning centuries, as explorers and scientists seek to understand the origins of life’s immense diversity. Shermer and Shubin also discuss:
• Darwin’s consilience of inductions (convergence of evidence) from multiple lines of inquiry
• how a scientific theory can gain acceptance without an underlying causal mechanism (evolutionary theory before DNA)
• what scientists should do with anomalies unexplained by the prevailing theory
• Does ontogeny recapitulate phylogeny? (What can we learn about evolution from embryology?)
• What is epigenetics, anyway?
• he best explanation for the origins of life
• how information can increase in a genome
• from microevolution to macroevolution: why creationists are wrong
• Are there hopeful monsters in evolution?
• Punctuated equilibrium and what it was like to be Steve Gould’s TA
• women in science, then and now
• What it’s like to do a paleontological dig north of the arctic circle? and
• Martian paleontology.
Neil Shubin is the author of Some Assembly Required, Your Inner Fish, and The Universe Within. He is the Robert R. Bensley Professor of Organismal Biology and Anatomy at the University of Chicago. He was elected to the National Academy of Sciences in 2011. He lives in Chicago.
This dialogue was recorded on March 13, 2020 as part of the Science Salon Podcast series hosted by Michael Shermer and presented by The Skeptics Society, in California.

Neil Shubin should do a star talk segment with neil de grasse on the topic of linking the poles to the cosmos... amazing work and discovery from an amazing paleontologist and a true inspiration to me.

At around 30:00 minutes in, I remember figuring out the continents had moved when I was 6 years old (1958) and saw a world map in my first grade class. I even commented to my teacher that I could see it plainly as South America and Africa obviously fitted together at one time. She, of course, told me I was wrong and that the continents were always where they were then. I didn't believe her and was happy to learn later that I was right. LOL

Donald Prothero claims (on Jackson Wheats You Tube channel) that (in his words) alot of paleontologists don't buy that a metroid is what caused the KT extinction since many forms of life in the Mesozoic were already dying off.

ReptileEvolution.com includes 1659 taxa (genera), including humans, bats, whales, turtles, snakes, dinosaurs, mammal-like reptiles, amphibian-like reptiles, frogs and fish all the way back to Cambrian chordates. With this cladogram (family tree) based on physical traits (not DNA) one can trace the ancestry of any included genus. Virtually all sister taxa look alike, so the gaps are small. Thus, with this cladogram one can also see how microevolution leads to macroevolution. Cladogram and links start here: reptileevolution.com/reptile-tree.htm

28:20. That's scary. It means that our organism would very easily be able to grow into one of the many other forms of life instead of us as human beings. All necessary instructions for this are available in the genome. Who will be the one to initiate this shift from one to the other?

about diversity of kinds of people to study -> when I was in medical school the anatomy laboratory had much more black males, and virtually no asians. do you think this was prejudicial for my formation? do you think that the anatomy of black x white x asian differences are enough that medical anatomical knowledge about one can't be extrapolated to the other?

I don't buy that she was told "genetics is not for women."

That makes sense, her research was in the 40s and 50s in the US, so she would of been told that in the 40s sometime. I completely buy it, her first genetics course was in 1921, society was very sexist back then

@johnlawrence2757 3 года назад

Charles Darwin was no longer involved with “O of S” by the fourth edition: he had relinquished all rights to the publisher. Darwin was never interested in evolution and particularly despised the idea of any b kind of speciation. He also resented the methods of the evolutionists - guesswork passed off as proven fact etc. He resented the imposition of what he regarded as crackpot theories on his cherished work of research into the flora and fauna of the islands, which as a biologist he regarded as pretty important in their own right This interview is a good example of how palaeontologists dress up their theories: they have laughably minute amounts of data yet they persist in talking about their guesses as fact. “We don’t know how fish evolved into creatures that could fly” The genetic evidence that Dawkins places so much emphasis on isn’t original research done by biologists - they would be unlikely to have access to the kind of resources or skills necessary to carry out that level of research. Molecular biologists themselves don’t support the conclusions he draws. In point of fact the deductions he makes only impress IF there is no such thing as intelligent design. If there is ID then the genome correlations are exactly what you would expect from the process - and by and large geneticists support the latter perception Indeed everything in nature points to a designer creation, a creation that goes wrong at every point - as you would expect it to - and just like human material activity life becomes a process of staggering from crisis to crisis, with each solution producing problems of its own.
