A model for the emergence of social organization in primates

Abstract

Recent studies have established a relationship between the repertoire of signals used for communication and neocortex size of different species of primates and the topology of the social network formed by the interactions between individuals. Inspired by these results, we have developed a model that qualitatively reproduces these observations. The model presents the social organization as a self-organized process where the size of the repertoire in one case and of the neocortex in another play a highly relevant role.
