Evolution is constantly adapting us to our environment, making species more suited and better equipped to survive in their natural habitat.

Professor Peter Ungar is a Paleoanthropologist, and author of 'Evolution’s Bite: A Story of Teeth, Diet, and Human Origins'.

He joins Jonathan to discuss what teeth can tell us. First Aired 28/7/2018
