Some aspects of hominid socioecology according to primatological data

A reconstruction of social structure and social relations in early hominids is proposed on the basis of modern data on primate socioecology. Relations between predator pressure and within-group structure, between the distribution of resources and competition within and between the groups is analyzed. General tendencies in the association between social structure (dominance, kin-clans) and the level of within-group cohesion is supposed to be universal for non-hominid primates and hominids. Models of aggression and peacemaking for hominids are proposed. The nature of male-female bonding and parental investment at different stages of hominid evolution appears to be linked with ecological and anatomical changes, as well as with cultural innovations (hunting, emergence of home bases).
