The Common Descent Podcast

Episode 98 - Species and Speciation

October 17, 2020

When we study life, past or present, we talk a lot about species, their evolution, their diversity, their extinction, and more. But we don’t often slow down to discuss what we really mean by that. What is a species? How and where do new species arise? It turns out this topic is much more complicated – and controversial! – than it may seem. In this episode, we’ll touch on the basics and discuss why scientists get so worked up about species and speciation.

In the news: a glass-ified brain, a Cretaceous croc, a long walk, and a sensitive dinosaur.
