What if everything we think we know about the history of our species is wrong? That’s the provocative question at the heart of a new book by today’s guest, David Wengrow. Hailed as fascinating, brilliant, and potentially revolutionary, “The Dawn of Everything: A New History of Humanity” debuted at no. 2 on the New York Times bestseller list. Drawing on the latest research in archeology and anthropology, it suggests that the lives of our ancient ancestors were not nasty, brutish, and short. On the contrary, they were playful, collaborative, and improvisational—and there's a lot they can teach us about how to improve the world as we know it.
