Dr. Briana Pobiner – What can cut marks tell us about human evolution, migration, and behavior?

Dr. Briana Pobiner of the Smithsonian National Museum of Natural History's Human Origins Program joins the show to talk about cut marks. She discusses how we can tell what's a cut mark vs. other bone damage and how cut marks can illuminate human evolution along with illustrating migration and behavioral patterns in the distant past.
