     Intergroup relations in wild primates are diverse, ranging from peaceful coexistence to violent territoriality. The reasons underlying this variation in intergroup dynamics, both among species, and among populations within species, remain obscure. Even in species noted for aggressive interactions, intergroup interactions occur infrequently and are difficult to observe systematically. Nonetheless, accumulating data from long-term field studies, and new field studies on less intensively studied species, makes possible a richer comparative perspective. Moreover, increased use of playback experiments has permitted more controlled testing of specific hypotheses. In this symposium we bring together researchers working on a broad spectrum of species, as well as several populations of one intensively studied species, chimpanzees, to examine causes underlying intergroup aggression.
