Abstract: Dispersal in some group-living animals have been reported, especially in non-human primates. Most primates species show male dispersal and female philopatry in their habitat. In a small number of species also show both sexes dispersal or females dispersal rather than males. There are some special dispersal models in solitary specie, monogamous specie and gregarious specie. The different model reflects different social organization. Individuals are forced to dispersal as the result of eviction and sexual attraction. Eviction occurs in male in one-male group and sexual attraction occurs between unfamiliar mates. The process of individual dispersal is a balance of cost and benefit Not only dispersal is a very important step of animal life history, but also it contributes to individual gene intercourse between different populations.
