FAYETTEVILLE, Ark. – "It was leaves, leaves and more leaves, but they have the teeth of a fruit-eater. ... Clearly these Macaques hadn't read the literature on tooth form and function."

What did our ancestors eat? What do their fossil remains — in this case, teeth — tell us about diet and evolution?

In this new episode of Short Talks From the Hill, a podcast from the University of Arkansas, Peter Ungar reads excerpts from Evolution's Bite, his new book about the fossil teeth of hominids, or human ancestors. He explains how these teeth offer clues about the diet of early humans and evolution.

Ungar is a Distinguished Professor of anthropology in the J. William Fulbright College of Arts and Sciences and director of the Environmental Dynamics Program at the University of Arkansas.

Short Talks From the Hill highlights research and scholarly work at the University of Arkansas. Each segment features a university researcher discussing his or her work.
