# Richard Wrangham

Richard Walter Wrangham (born 1948) is an English anthropologist and primatologist; he is Professor of Biological Anthropology at Harvard University. His research and writing have involved ape behavior, human evolution, violence, and cooking.

## Biography

Wrangham was born in Leeds, Yorkshire.
Following his years on the faculty of the University of Michigan, he became the Ruth Moore Professor of Biological Anthropology at Harvard University and his research group is now part of the newly established Department of Human Evolutionary Biology. He is a MacArthur fellow.
He is co-director of the Kibale Chimpanzee Project, the long-term study of the Kanyawara chimpanzees in Kibale National Park, Uganda. His research culminates in the study of human evolution in which he draws conclusions based on the behavioural ecology of apes. As a graduate student, Wrangham studied under Robert Hinde and Jane Goodall.
Wrangham is known predominantly for his work in the ecology of primate social systems, the evolutionary history of human aggression (in his 1996 book with Dale Peterson, Demonic Males: Apes and the Origins of Human Violence and his 2019 work The Goodness Paradox), and his research in cooking (summarized in his book, Catching Fire: How Cooking Made Us Human) and self-domestication.
Wrangham has been instrumental in identifying behaviors considered "human-specific" in chimpanzees, including culture and with Eloy Rodriguez, chimpanzee self-medication.
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.

## Research

Wrangham began his career as a researcher at Jane Goodall's long-term common chimpanzee field study in Gombe Stream National Park in Tanzania. He befriended fellow primatologist Dian Fossey and assisted her in setting up her nonprofit mountain gorilla conservation organization, the Dian Fossey Gorilla Fund (originally the Digit Fund).
Wrangham has focused recently on the role cooking has played in human evolution. In Catching Fire: How Cooking Made Us Human, he 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, arguing that no solid evidence has been found to support Wrangham's claims, though Wrangham and colleagues, among others, have demonstrated in the laboratory the effects of cooking on energetic availability: cooking denatures proteins, gelatinizes starches, 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.

## Personal life

Wrangham married Elizabeth Ross in 1980 and has three sons. His work of studying the essential violence of chimpanzees caused Wrangham to not eat meat for 40 years.
