Changing Landscapes, Changing Diets: How Fossilized Teeth Reveal Dietary Shifts

Using fossilized teeth uncovered in Ethiopia, a team led by CASHP postdoctoral researcher Enquye Negash traced how an ecological change nearly 3 million years ago forced a dietary shift among ancient herbivores like antelopes and pigs.

Changes in Human Diet Shed Light on Human Evolution

A study led by David Patterson, PhD ‘16, finds a dietary shift about 1.65 million years ago when the genus Homo incorporated vegetation into their meals, demonstrating a divergence from earlier human ancestors.
