“What good is half a wing?” That’s the rhetorical question often asked by people who have trouble accepting Darwin’s theory of evolution by natural selection. Of course it’s a very answerable question, but figuring out what exactly the answer is leads us to some fascinating biology. Neil Shubin should know: he is the co-discoverer of Tiktaalik Roseae, an ancient species of fish that was in the process of learning to walk and breathe on land. We talk about how these major transitions happen - typically when evolution finds a way to re-purpose existing organs into new roles - and how we can learn about them by studying living creatures and the information contained in their genomes.
Neil Shubin received his Ph.D. in organismic and evolutionary biology from Harvard University. He is currently the the Robert Bensley Distinguished Service Professor and Associate Dean of Biological Sciences at the University of Chicago. He is a member of the National Academy of Sciences and the American Philosophical society. His first book, Your Inner Fish, was chosen by the National Academy of Sciences as the best science book of 2009, and was subsequently made into a TV special. His new book is Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA.
Argh, sorry about the outro music coming in early. No way to fix it on UA-cam, unfortunately.
You're the man Sean. Thanks for Everything you do. Most people dream of meeting people like Brad Pitt, or The Rock, or Taylor Swift, but you're pretty high up there on my list. 🙏✌
NP
No worries!
I have started to like mondays, because of these mindscape episodes. Thanks Sean Carroll!
As a grad student researching skeletal evolution using the amphibian as an animal model, and who has an even greater fascination for physics, I can't even begin to describe how timely this podcast is.
Sorry to be so off topic but does anybody know a trick to get back into an Instagram account??
I was dumb lost the login password. I appreciate any tips you can offer me!
@Jericho Kayson instablaster :)
@Kian Zechariah thanks for your reply. I found the site thru google and I'm trying it out now.
Seems to take quite some time so I will reply here later with my results.
@Kian Zechariah It did the trick and I actually got access to my account again. I am so happy!
Thank you so much, you saved my ass !
@Jericho Kayson Glad I could help :)
Wowsers! These podcasts are getting better and better. This one was jam-packed with great information. Just amazing!
Greatest podcast around! Love ya Sean keep doing your thing buddy...
I want that guy's book. Judging by how well spoken he is, his writing skills should be phenomenal.
He did a 3 part series for Your Inner Fish that is simply fantastic.
Neil writes exactly as he speaks as well.
@@jamierichardson7683 I already bought them starting Inner Fish tonight! Thanks for that info, I'll look for it.
"Well, I don't know about [humans being] superior. [Salamanders] can flick their tongue their whole body length in a millisecond, some of these things, so that's pretty superior. Depends how you measure it." 52:44
Chicks dig that
Thanks for the podcast. The outro music was a bit early, though... 1:30:27
Wonderfully enlightening interview. Thank you Sean.
Just a minor caveat. At 1:17. Trying to remove Darwin from current discoveries on evolution is like trying to remove Einstein from current theories on quantum gravity. Evolution is just as synonymous with Darwin as relativity is with Einstein.
26:30 „Nothing, of course, ever begins when you think it does.“
An online family tree including 1656 vertebrates allows one to trace the ancestry of any included genus back to Cambrian lancelets (= basal chordates, pre-fish). That list includes Tiktaalik, bats, snakes, whales, pterosaurs, dinosaurs, etc. There are no major gaps here: reptileevolution.com/reptile-tree.htm
Amazing episode.
Hi Sean, I love mindscape and you’re voice 😀. There is one conversation I’m really missing. Please organize a talk with Donald Hofman. The world is missing that conversation ✌️.
The ending misplaced outro was awesome
hey sean carroll, when are you going to interview sean carroll?
I didn't read the book, but I saw the TV show and look forward to the movie, the musical, and to collecting the playing cards w/ chewing gun.
"We can take the genes from a mouse, and put them in a fish, and see what they do. We can take the fish genes and put them in a mouse and see what they do in that new environment-turns out they function very well. I can take a shark gene, from the fin, and put it in a mouse-from a SHARK-and it does perfectly fine. Likewise the mouse one in the shark. We can make these swaps. We can also knock these genes out. [...] So yeah, it's a real, you know, house of horrors here. [maniacal laughter]" 1:23:44
Inner Fish is an incredible book. I've forced my woman and my siblings to read it cuz that's what I evolved to do. Yay me!
56:18 "the gene part of our genome, that part that makes proteins, is only 2% of our genome (...) the rest of it kind of controls the activity of those things"
on hiccups: if you have someone plug your ears and take a swallow of a drink, they are gone. 🐸
I had to listen twice, def had outro music before the outro? otherwise 10/10 :)
We can't expect Sean to be an audio engineer/video editor AND a top physicist.
Please get Lee Smolin or Nick Lane...Joseph Le Doux?
Will the study of AI, specifically, the optimising of structures that produce efficient solutions to problems, give us insight into why there is so much redundancy in genetic systems? Seems inefficient, all that wasted resource. Maybe it's a backup strategy.
Thanks
christmas is approaching, can we get a christmas carroll this year?
Dang, all this talk about Fins and Rays, it’s kinda making me want to watch those new Star War movies!
Lol jk I don’t watch kids’ movies that are stupid
Steven Gordon you don’t stop playing because you get old, you get old because you stop playing.
this is a bit over the top with adds :))))
well thanks god it's not about viruses and pandemics
Pandora’s Door... ‘Panboxa’?
Isn't the Caterpillar metamorphic to butterfly analogous to the salamander kind of?
who dislikes this? 5 people? religious fundamentalists?
I propose to write a list for Sean: How and What to Say or Act to Appear Human:
I start...
1. When others start laughing you laugh along to signal non threatening message. No laugh is a blatant attack on your guest.
2. Adopt to different levels of authority of your guests, with a wise elder show an emotion of awe, regardless of wether they deserve it or not, it’s the ritual that matters. With younger generation you could be dismissive and arrogant. But, Sean, when you have no variation in your manners and styles of speaking it may send again a threatening signal, for ex., that you don’t value hierarchy, which is insane and it is not you Sean.
3. Always, always recognize the toils and suffering that each speaker went through on the passage of discovery. I don’t recommend giving a curt “good” or “that’s right” when it is revealed how magic works. Could you please show a little humility by embracing a sense of wonder and curiosity.
4.
Each person behaves according to their own experiences and beliefs. Sean did laugh several times and posed valuable questions in this interview that allowed Neil to express important ideas of his work to the general public without Sean behaving in a submissive manner, which seems what your suggestions are conveying... In my view, those wouldn't make Sean "act or appear human" at all, but they'd discard all honest and natural reactions and curiosity to what is being said.
There's something really creepy about your criticism. I can't pinpoint it, but I'd stay away from communicating with you. It smacks of being manipulative
Hey look, a smarty pants from Philly, are we in dystopia and not aware of it??
Sean, get Tom Campbell! next big step for science, pls wake uuupp
@Gil pls feel free to elaborate, how come u know for sure? i am open minded to your perspective, but boldly claiming he is a fraud is possibly due to your limited view on reality, your ego, your reducing western belief system trap or simply lack of experience when it comes to the potential of consciousness. pioneers like tom campbell have always been considered fake before paradigm shifts were accepted by mainstream.
Thanks
