The second episode of Science Life is here, and the first remote one! I skyped with Yale professor of ornithology Richard Prum just before releasing my latest video, and it was a super cool conversation. Here we start off pondering why birds are so fascinating, and talking about the ways in which, weirdly, birds are more like people than a lot of mammals are. Then we get into the evidence for birds being the descendants of reptilian dinosaurs: Their bone structure, their mating habits, and the feathers that originated back before T-Rex. We also talk about how our understanding of oviraptor went from sneaky egg their to communally caring dad. Then we talk about how beauty emerges as a result of choices, both in birds and in flowers. Then we get into the tubular evolution of feathers, before returning to choice in the form of the sometimes-disturbing sexual practices of ducks and and the more cultured bowerbird dating scene.
Finally, we get into how a young person might become part of the next generation of great ornithologists, why minds matter in evolution, and why some dissident and reckless voices in science are crucial to its survival!

Hey, you just got a shout-out on NPR!!!!! Way to go!!!!
This is so fascinating! I took a MN birds Class in College held at the Dodge Nature Center. I can see now how it just scratched the surface. I had no idea of the dinosaur correlation.
I didn't know that the Fisherian runaway was controversial at all. I thought that that was THE main explanation of features that don't have a straight up survival advantage. Maths aside it's a really simple idea and there's analogues in culture and game theory.
Chemistry song please. I know how hard it is to make a song, and I love them all, i will listen to any of your song
Hey, can you tell me why gravity increases when objects get more dense? I mean a star that collapses into a black hole shoud by my views also not let light escape from his gravitational pull, when it is still a star. That because the mass of the star makes the star have gravity, and the amount of matter doesn't rise when the star collapses, right?

I'm no physicist, but I can answer that question, I think. The crux is, that the sun's entire mass isn't concentrated in the core but spread out through the entire sphere. If you were to move inside the sun, the gravitational pull towards the centre would decrease continuously, because there is less matter in front of you pulling you to the centre. Yet, if the sun would collapse as you are inside of it and turn into a black hole, the mass that used to be all around you is now focused into one tiny point, thus the gravitational pull can grow further than before.

I am a physicist, and you've captured the essence of the explanation perfectly. It would be hard to go into more detail without using integral calculus or at least some informative drawings.

@@seanehle8323 You could simply say that in a less dense object more mass is pulling you up/down, left/right, which cancels out, and thetefore less towards the center of mass.

Because this video is the full version of a two parts video that came out a few weeks before this one. The 2 parts version is non-listed, which means it doesn't show up in the channel page or searches. But they were linked from the "More Than Birds" music video and probably patreon as well
