Summary

The Earth is in motion beneath our feet. The shifting and grinding of the tectonic plates is responsible for the shape of our planet’s surface and – directly or indirectly – nearly all the activity that happens upon it. Plate tectonics has a deep and fascinating history, both as a force that has shaped the Earth for billions of years and as a surprisingly recent foundational scientific theory. In the news: shark teeth, Cambrian predators, Carnotaurus skin, and teratorns.

0:00.0	You're listening to the Common Descent Podcast.
0:19.0	Hello, Will. Hello, David. Hello, listeners, and welcome to episode 122 of the Common Descent
0:25.7	podcast. This is a podcast about paleontology, earth history, life history, evolution,
0:30.6	and so on. And today's topic is plate tectonics. Yeah. I'm ready to learn about this one,
0:37.4	because this is, this is geology stuff.
0:40.0	And I am so excited to talk about it because we, you know, mostly we err on the biology side
0:46.4	of paleontology here on our podcast, but we do touch on geology stuff every now and then. I
0:51.9	always get very excited, and this is a topic that I think
0:54.7	is super cool and foundational. Literally. So yes, literally foundational. So we're going to explore a
1:03.0	scientific concept that is also a feature of our planet past and present. So we'll talk about
1:10.2	what Playtectonics is. We'll have a bit of a crash'll talk about what Playtectonics is.
1:11.7	We'll have a bit of a crash course and what is Playtectonics.
1:14.5	We'll talk about the history of Playtectonics, both the history of like what has happened
1:20.9	over the course of Earth history and the history of the science of Playtectonics.
1:26.6	How has this extraordinary theory come to be?
1:31.4	I'm excited for this one, because this is one, we've mentioned the effects of plate tectonics
1:36.2	so much on this. Most episodes probably touch on it at least a little bit. Yeah, but we've not
1:42.6	actually gotten into what it is or how we know
1:46.3	about it. So I'm really excited to learn about, and I'm excited to learn because I am not a geology
1:51.4	person. So I've learned a lot. I have taught Play Tetonics to college students, so I'm all ready for it.
1:58.8	In addition to being a cool topic, we are doing this
2:01.6	episode because this was requested, as all our episodes are. This episode, topics requesters were
