Summary

Powered flight is hard, and evolution has only produced it a few times. Gliding, however, is much easier and much more common. In fact, there is an astonishing diversity of gliding organisms to be found in our modern world as well as in the fossil record, with an incredible variety in the adaptations they use to sail through the sky. This episode, we’ll explore what it takes to glide and what patterns we see in gliding evolution, and we’ll also geek out about all the amazing sizes, shapes, and strategies of gliders. In the news: coral mutations, African dinosaurs, croc brains, and ancient amputation.

0:19.0	Hello, Will.
0:20.2	Hello, David. Hello, David.
0:21.3	Hello, listeners, and welcome to the Common Descent podcast, episode 148.
0:27.6	As you know, this podcast, we talk about paleontology, life history, evolution, all sorts of
0:31.9	cool stuff about the history and diversity of life on Earth.
0:34.4	This episode's topic is gliding.
0:37.9	Yeah.
0:38.9	We have talked about flight on this podcast a bunch.
0:43.5	Yes.
0:43.9	A whole episode about the evolution of flight, episode six.
0:46.1	We have done episodes on every group of flying animals that there is.
0:52.2	This episode, we are talking about flights next door neighbor, gliding.
0:57.2	Falling with style.
0:58.1	Falling with style in a whole bunch of different wacky cool ways.
1:01.8	Gliding is extremely widespread among the organisms of Earth.
1:08.2	There are all sorts of different things that do it in all sorts of different
1:11.4	cool ways. No, it gets real weird. It is a fascinating convergent feature that has evolved many,
1:19.1	many, many times. This episode, we're going to talk about what gliding technically is, how it's
1:24.8	different from flight, what's good about it, a bit of what we
1:27.9	understand about evolutionary patterns in gliding, but mostly we're going to geek out over
1:34.5	the diversity of gliders in the modern day and also what we know about gliding in the
