History: Darwin, Walcott, and the Puzzle

In this episode, we’re discussing the dramatic event that saw the rise of modern animal life and formed the foundation for all animal ecosystems – an event as fascinating as it is mysterious – the Cambrian Explosion!

In the news: brand new armored dinosaurs, a long-lost dino-baby, surprises from the human family tree, and snake fossils from our favorite fossil site!
