Extinctions: The (Maybe) Cambrian (Not Really) Explosion

The Cambrian explosion is commonly labelled as the time in Earth’s history when animals suddenly appear. But research from geoscientist Rachel Wood and her team turns this explanation on its head. We talked with Rachel about how this research changes our understanding of how animals arose on Earth and about whether we can even call this event the “Cambrian explosion,” anymore.This episode was produced by Molly Magid and mixed by Collin Warren.
