Ph.D. University of California-Davis 1981
Joan Silk moved to Arizona State University’s School of Human Evolution and Social Change in 2012, from University of California, Los Angeles (UCLA). She is interested in how natural selection shapes the evolution of social behavior in primates. Most of Silk’s empirical work has focused on the behavioral and reproductive strategies of female baboon. She recently initiated a comparative study of the structure and function of close social bonds in four baboon species (anubis, hamadryas, gelada, and chacma). In particular, Silk is interested in questions that explicitly link studies of nonhuman primates to humans. Experimental work she conducts with chimpanzees and children focuses on the phylogenetic origins and ontogenetic development of prosocial preferences.
Silk received her doctorate from University of California at Davis in 1981, and spent two years as a postdoctoral fellow in the Altmann’s lab at the University of Chicago. She then joined the Department of Anthropology at Emory University. Silk moved to UCLA in 1986, where she remained until 2012. At UCLA, she was a founding member of the Center of Behavior, Evolution, and Culture and served as department chair for six years.
