What distinguishes humans from their closest evolutionary ancestors? Anthropologist Craig Stanford believes that upright posture is what made us human since it led to the development of a larger brain size and by freeing our lungs, to the ability to use speech. He joins Larry Mantle for a conversation about what, in evolutionary terms propelled us to become human. Professor Stanford's new book is called Upright: The Evolutionary Key to Becoming Human (Houghton Mifflin.)
