The 81st Annual Meeting of the American Association of Physical Anthropologists (2012)


Session 24. Finding our inner animal: understanding human evolutionary variation via experimental model systems. Invited Podium Symposium. Chair: Nathan M. Young and Maureen J. Devlin

Friday Afternoon, Galleria South Add to calendar

Non-primate animal models have become an increasingly important component of research in physical anthropology. In particular, controlled animal studies enable testing and refinement of evolutionary hypotheses by providing experimental and comparative data that can then be correlated with observational studies in living human and non-human primates. This symposium showcases exciting new research by physical anthropologists at the forefront of this approach. Each speaker will discuss how animal model systems are important and relevant to anthropological inquiry by addressing one of two key questions: (1) how has diet impacted human evolutionary variation, and (2) what is the genetic and/or developmental basis for evolutionary variation in the human skull, limbs and teeth? The ultimate goal of this symposium is to help foster the continued integration of experimental comparative biology with physical anthropology.
