Evolution is constantly adapting us to our environment, making species more suited and better equipped to survive in their natural habitat.\n\nSo why did our distant ancestors have better teeth than we do? And what can the study of our gnashers tell us about our diet, our oral health, and our very origins as a species?\n\nProfessor Peter Ungar is a Paleoanthropologist, and author of 'Evolution\u2019s Bite: A Story of Teeth, Diet, and Human Origins'.\n\nHe joins Jonathan to discuss what teeth can tell us.
