Episode 161 - Sleep

We spend a huge portion of our lives sleeping. For us and other animals, it’s clearly a very important behavior. And yet, despite how familiar and commonplace it is, there’s plenty we still don’t understand about sleep: its origins, evolution, and even how to define it in the first place. In this episode, we explore some of the remarkable variation in animal sleeping habits, we discuss some of the ways we study and understand sleep, and we touch upon the crucial – and much debated – question of what sleep even does for us anyway.

In the news: early monotremes, chunky dunk, Permian pollinators, and parasitic ant mutations.
