Evolution of Human Diet

This is a collaborative project with Greg Wray (Duke, Dept. of Biology) and Sarah Tishkoff (University of Pennsylvania, Dept. of Genetics) that brings together a group of researchers attempting to link genomics, physiology, and morphology to study the evolution of diet in humans and chimpanzees.

Energetic Costs of Feeding in Primates

This is a long-term project to collect novel data on the energetic costs of feeding behaviors in primates.  Animals eat because they need energy to live and reproduce, but we know almost nothing about how much it costs primates to eat or how these costs are related to the evolution of feeding structures.  Respirometry measurements combined with simultaneous digital video recordings are being collected for 14 primate species ranging in size from 60 g (Microcebus murinus) to 80,000 g (human).  We are quantifying how the energetic costs of feeding scale relative to body mass, to morphological

Overview

We are a group of functional anatomists who work on a variety of questions related to understanding the mechanisms through which diet and feeding behaviors have shaped primate evolution. The diversity of primate diets and feeding mechanisms are reflected in the design of skull structures, and teeth and jaws comprise the most abundant fossil record of primate evolution.
