Episode notes

Paleontologists are always talking about family trees and what's related to what. Mammals started on land, way back in the coal forest times. The first mammals that evolved hair and warm blooded metabolism were living on land. About 55 million years ago, we start to see fossils of a little mammal called Woofs. This was a mammal that lived on the land, but there's a few features its skeleton shows it had after other animals. These things might be useful for people who want to understand our evolutionary past.

In times of turmoil, it can be useful to take a longer view of history. Like, a LOT longer. Paleontologist and author of “The Rise and Reign of the Mammals” Stephen Brusatte joins Adam to explain how mammals took over the Earth hundreds of millions of years ago, and why we survived and achieve sentience when dinosaurs died out. Stephen goes on to discuss why taking a deep look at our history can help prepare us for the crises of the near future.
