Currently Playing: The Biggest Extinction You’ve Never Heard Of

In the early 20th century, it was discovered there was a point in the fossil record where most European mammals just…vanished, only to be replaced with others native to Asia. While you’ve probably never heard of this extinction, it was the biggest one since the end of the dinosaurs, nearly taking out our primate ancestors, and by extension, us. ***** PBS Member Stations rely on viewers like you.
