Primate sociality is an area of primatology that aims to study the interactions between three main elements of a primate social network: the social organisation, the social structure and the mating system. The intersection of these three structures describe the socially complex behaviours and relationships occurring among adult males and ...
Chimpanzees live in a leaner hierarchy wherein more than one individual may be dominant enough to dominate other members of lower rank. Typically, a dominant male is referred to as the alpha male . The alpha male is the highest-ranking male that controls the group and maintains order during disputes.
Positions within the hierarchy correlate with territoriality, courtship rate, nest size, aggression, and hormone production. [36] In terms of social structure, Mozambique tilapias engage in a system known as lek-breeding, where males establish territories with dominance hierarchies while females travel between them. Social hierarchies typically ...
Male chimpanzees exist in a linear dominance hierarchy. Top-ranking males tend to be aggressive even during dominance stability. [89] This is probably due to the chimpanzee's fission-fusion society, with male chimpanzees leaving groups and returning after extended periods of time.
The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes).

Dunbar's number has become of interest in anthropology, evolutionary psychology, [12] statistics, and business management.For example, developers of social software are interested in it, as they need to know the size of social networks their software needs to take into account; and in the modern military, operational psychologists seek such data to support or refute policies related to ...
Central chimpanzees live in social groups of around 66 individuals, on average this tends to be more than the group size of western chimpanzee counterparts. It was found that chimpanzees split activity budget into four main categories. [5] In chimpanzees there exists male dominance within these social groups.
Group of chimpanzees. In primatology, the Machiavellian intelligence or social brain hypothesis describes the capacity of primates to manuever in complex social groups. [1] [2] The first introduction of this concept came from Frans de Waal's book Chimpanzee Politics (1982). In the book de Waal notes that chimpanzees performed certain social ...
