We've all heard of "The Paleo Diet", but what did our paleolithic ancestors

actually eat? Well we found exactly the scientist to ask. Briana Pobiner

is a paleoanthropologist whose research centers on the evolution of human

diet. We discuss when and why humans started eating meat. We also had to

ask her about the dream job she has at the Smithsonian National Museum of

Natural History, where she helped put together the Human Origins exhibit.

Listen in to hear more about education, evolution and the history behind

our eating habits.
