Some anthropologists and primatologists have argued that, judging by extant chimpanzees and humans, which are female‐biased dispersers, the common ancestors of humans and chimpanzees were also female‐biased dispersers. It has been thought that sex‐biased dispersal patterns have been genetically transmitted for millions of years. However, this character has changed many times with changes in environment and life‐form during human evolution and historical times. I examined life‐form and social organization of nonhuman primates, among them gatherers (foragers), hunter‐gatherers, agriculturalists, industrialists, and modern and extant humans. I conclude that dispersal patterns changed in response to environmental conditions during primate and human evolution.
