Description

Evolution involves the innovation of new features, but even more reduction of old features. Those reduced features might disappear, develop in a new direction, or just linger as a functionless evidence of deep ancestry. This episode, we explore how we identify vestigial traits, how they help us understand evolutionary history, and the various evolutionary paths vestigial structures can take.


In the news: giant worm lizards, drumstick evolution, dinosaur poop, and pterosaur transitions.
