Among the recent courses he teaches in the Human Evolutionary Biology (HEB) concentration at Harvard are HEB 1330 Primate Social Behaviour and HEB 1565 Theories of Sexual Coercion (co-taught with Professor Diane Rosenfeld from Harvard Law School). In March 2008, he was appointed House Master of Currier House at Harvard College. He received an honorary degree in Doctor of Science from Oglethorpe University in 2011.
Wrangham's latest work focuses on the role cooking has played in human evolution. He has argued that cooking food is obligatory for humans as a result of biological adaptations and that cooking, in particular the consumption of cooked tubers, might explain the increase in hominid brain sizes, smaller teeth and jaws, and decrease in sexual dimorphism that occurred roughly 1.8 million years ago. Some anthropologists disagree with Wrangham's ideas, pointing out that there is no solid evidence to support Wrangham's claims., though Wrangham and colleagues, among others, have demonstrated in the lab the effects of cooking on energetic availability: cooking denatures proteins, gelatinizes starch, and helps kill pathogens. The mainstream explanation is that human ancestors, prior to the advent of cooking, turned to eating meats, which then caused the evolutionary shift to smaller guts and larger brains.
