The Ape That Cooks

What did you have for your Christmas dinner? The traditional turkey? A vegetarian meal? And how did the turkey tradition start? What did people have for Christmas dinner 500 years ago? Just how is your Christmas meal turned into you? John takes us on a journey through time from our earliest ancestors, on the way exploring how scientists have come to understand the diets of our fossil ancestors from studying their teeth and bones and how differences in food habits among populations and cultures have arisen.
