Australopithecus boisei (Nutcracker Man)

Mary Leakey was called the "grand dame" of archaeology. She was a methodical and exacting scientist who made some of the world's most significant archaeological discoveries. In this lecture from The Leakey Foundation archive, Mary Leakey tells the story of Olduvai Gorge, the place where she found fossils that completely changed our understanding of human origins.
