A progress report that outlines the kinds of studies of primate behavior and variability that still need to be made. Written by eminent authorities in the fields of anthropology, psychology, zoology, and psychiatry, the selections in this volume concern primate social behavior, adaptation, and variation.

"Based on the results of a symposium on primate social behavior sponsored by the Wenner-Gren Foundation for Anthropological Research and held at ... Burg Wartenstein, Austria."
