Studs talks with Donald Johanson about his book "Lucy: The Beginnings of Humankind," in which the famed paleoanthropologist describes his discovery of the female hominin fossil in Ethiopia. The conversation includes talk of Charles Darwin, Eugène Dubois' Java Man discovery, what makes a hominid, holes in the fossil record, fossil dating, his disagreements with Louis and Richard Leakey, site discovery, and his belief that the Hadar Formation in the Afar Triangle of Ethiopia holds the keys to the evolutionary puzzle. Includes snippets of the Beatles' "Lucy in the Sky with Diamonds."

Photographers Carol Beckwith and Angela Fisher discuss their book “African Ark: People and Ancient Cultures of Ethiopia and the Horn of Africa.” The two discuss the cultural traditions of the indigenous groups from this region in Africa and the relationships they formed with these communities during this photography project. Studs plays an unnamed traditional Surma warrior song.
