Abstract

Eight discrete cranial traits are used as biological indicators to investigate the effect of social group fission on intragroup genetic change leading to intergroup differentiation in Macaca mulatta. The timing of discrete cranial trait frequency change and group fission coincide, indicating a possible causal relationship between fission and genetic change. A significant change in the male mating population during and after fission is proposed as the mechanism causing intragroup genetic change, along with the effects of fluctuations in segregation ratios.
