PBS Eons has a new video. This one is about the mass extinction caused by the migration of India during the Paleogene.

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.
