The Common Descent Podcast

Episode 78 - Exaptation

January 11, 2020

Hand a kitchen appliance to a child and they’re likely to find a whole new way to use it. This happens in evolution, too – traits adapted for one purpose turn out to be beneficial for a whole other reason, and so the trajectory of natural selection changes. The term for this is exaptation, but it’s a complicated concept, and not everyone even likes using the word. Let’s discuss what this word means, why it exists, and what some people find wrong with it.

In the news: the oldest forest, an ancient parent, young T. rex, and fossil lungfish.
