In the last few decades, new sources of evidence have continued to indicate that male violence has played an important role in shaping behavior in the human lineage. The frequency and nature of such violence vary widely among populations and over time raises questions about the factors responsible for the variation. This symposium takes a fresh look at the causes and consequences of variation in aggression, both between and within species.


Donald Pfaff (Rockefeller Univ) begins with a discussion about Neuroendocrine Mechanisms Underlying Male Aggression, followed by Anne Pusey (Duke Univ) on Intergroup Violence: Chimpanzees and Lions, and Richard Wrangham (Harvard Univ) on Parallel Evolution of Humanity and Savagery.

Symposium hosted by the University of California and The Center for Academic Research and Training in Anthropogeny (CARTA).
