Summary

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.

Hi, and welcome to The Origins Podcast. I'm your host, Lawrence Krause.

0:13.0

In this episode, I had the distinct pleasure and privilege to talk to an old friend and colleague,

0:17.0

a distinguished scientist, a biologist, paleontologist, Neil Schubin, from the University

0:22.9

of Chicago, who has written a new book called The Ends of the Earth, Journeys to the Polar

0:27.8

Regions in Search of Life, the Cosmos, and Our Future. Neil attained fame as a scientist for

0:35.2

discovering a fossil, which he called Tictaluk, which I think is an Inuit word,

0:40.9

but it describes basically the first evidence of a fish with legs, a fish that the first

0:47.2

transitional fossil as fish began to evolve into animals that could live on land, the important missing link in the

0:55.9

history of evolution of life on earth. And that got him fame as a scientist. His book at the time,

1:01.6

Uraner Fish, which later got turned into a TV series, also was a best-selling book at the time.

1:06.8

And this new book is equally interesting in so many ways.

1:11.6

It describes the challenge of doing science in a polar region where he spent a lot of his time since as a graduate student.

1:18.2

I'm a little familiar with that, having spent time in Antarctica and also in Greenland.

1:23.4

And I know the amazing science has been done there.

1:25.9

And it has an impact not just on our

1:28.4

understanding of our own human evolution, but the evolution of the Earth itself, going back

1:34.0

and understanding our climate back a million years, understanding how quickly the climate can

1:38.0

change, how ice itself can move so much faster than you can imagine.

1:43.1

And also not just the Earth, but the cosmos.

1:46.0

Because in Antarctic, at least, you can look for meteorites.

1:51.0

And meteorites that not just tell us about the beginning of the solar system,

1:55.0

but meteorites from Mars, which may one day reveal more information about life on Mars.
