Summary

A lot of life on Earth happens underground. This episode, we sample the species that have taken to a life of digging in the dirt – and elsewhere – why they do it and what physical adaptations help them along the way. Then, we’ll take a tour of burrows in the fossil record and explore what clues paleontologists can use to determine which ancient critter constructed a given burrow. In the news: malaria history, false octopus, pterosaur tracks, and giant octopus.

Hello, David. Hello, Will.

And hello, listeners.

Welcome to episode 243 of the Common Descent Podcast.

0:28.8

This episode, we will be discussing burrowing or burrowers, the act and adaptations for digging and living underground.

0:39.3

This will be a very interesting topic, but like many behavioral topics, it's going to be vast, because a lot of animals like to go beneath the surface.

0:51.3

Yeah, we'll get to talk about some of our favorites and some of the standout examples,

0:56.4

but this is going to be one of those where it will be incumbent upon you, dear listener, to go to

1:01.4

the Discord and let all of your fellow listeners know your favorite examples that we missed.

1:08.2

That we slighted by snubbing from the episode.

1:13.3

Rest assured that if there is an animal that is relevant that we didn't mention, it is because we

1:19.8

hate them. Yes, absolutely. Like, this is the official stance. Yeah, that that is, that is how you can

1:25.3

tell. 100%. During this discussion, we'll be going over what is burrowing in its benefits, what are some

1:33.7

of the general typical adaptations you often see in digging animals, and then of course,

1:40.7

the fossil record of burrows, which is vast, and the more difficult task of how do you

1:46.0

identify who burrowed the borough that you have found. We'll be discussing this because it was

1:52.6

requested quite a few times, as all our episodes are requested these days. We got requests

1:58.6

for this topic from Nina, Kylie, Aaron, Kai, Tobias, Sam and Sierra,

2:04.6

Big Bossman, A Zola Event, Helpless Droid, and KamenSaurus. Thank you, everybody, for your requests.

2:12.7

We're taking requests for episode topics. Constantly, you can submit them to these days to the topic request

forum on our website. Link in the episode description. Absolutely. Before we get into the discussion
