Summary

Volcanoes are fascinating, devastating, and fundamental to Earth systems. Volcanic eruptions can transform ecosystems, landscapes, and even the atmosphere, and at their most extreme, the effects of volcanism can be global and long-lasting. In this overstuffed episode, we discuss the many forms and features of volcanic activity, and we take a look at the complex and dramatic interaction between volcanoes and life on Earth. In the news: ankylosaur brains, an Australian rainforest, donkey hybrids, and the Tonga volcanic eruption.

0:00.0	You're listening to the Common Descent Podcast.
0:18.8	Hello, Will. Hello, David.
0:26.5	Hello, listeners, and welcome to episode 131 of the Common Descent podcast.
0:29.7	This episode's topic is Volcanoes.
0:30.6	Ooh.
0:32.3	A very exciting topic.
0:34.9	A bit more geology for the people that like that. And also, totally by coincidence, a very timely episode topic.
0:39.3	Right.
0:40.1	This is the first episode we will be releasing after the major eruption that happened in Tonga shortly before this recording.
0:50.0	And that is not planned. We picked this episode topic months ago. So that is a total coincidence.
0:55.6	But we will talk about that particular series of events here in just a little bit.
1:00.5	But the majority of this episode, we are going to, as with everything, come at the topic from a paleontological, deep time evolutionary perspective.
1:09.6	We will talk about what volcanoes are, how they form, how we
1:13.4	study them in the past, and the relationship between volcanoes and life. Yes. How volcanoes interact with
1:22.0	life today and what their storied history has been together across the history of life on Earth.
1:28.6	As usual with the geotophics, I'm very excited to learn just a ton.
1:32.9	I know more about volcanoes than I thought that I knew, but now I have a ton of great new
1:37.6	information to share. This is going to be a lot of fun. For those people, by the way, who follow
1:41.1	us on social media, we have a habit oftentimes of posting teaser
1:45.6	images that sort of are a clue as to what the episode's going to be about, and sometimes they're
1:51.0	more obscure than others. So for those of you wondering, the teaser image we posted in advance of this
1:56.1	episode is curved ash layers in an outcrop in Japan.
