The study of the evolutionary and genetic source of behaviour in primates is called socio-biology. Culture, like language, is not entirely explicable through genetics. Behaviours which increase the survival and reproduction of an individual's siblings actually increases the fitness of the individual. Altruism is an example of behaviour that expresses inclusive fitness. Behaviour which benefits others without regard for one's own fitness.
Reproductive strategies are the behaviours which maximize an individual's fitness.
Traditional Interpretation of Baboon Social Organization. Females subordinate to a social order imposed by males. This model was developed in the 1950's and 1960's by researchers who were mostly male. Revised Interpretation of Baboon Social Organization Baboon social organization is more fluid than previously thought, with females and males switching groups. Males are not dominant over females.
