Most primates live in social groups in which affiliative bonds exist between individuals. Because these bonds need to be maintained through social interactions (grooming in most primates), sociality will be limited by time constraints. It has previously been shown that the time primates invest in grooming increases with group size. However, when groups become too large, individuals will not have enough time available to service all possible social relationships and group cohesion is expected to… Expand

Group size, grooming and fission in primates: a modeling approach based on group structure.
TLDR
A computational model is developed to assess how dynamics of group cohesion are related to group size and to the structure of grooming relationships and showed that the relationship between grooming time and group size is dependent on how each individual attributes grooming time to its social partners.

TLDR
The differences in fertility and network structure both predict the very different maximum group sizes typical of these two species, as well as the typical sizes at which their groups undergo fission, which may explain aspects of wider mammalian sociality. Expand
Grooming and group cohesion in primates: implications for the evolution of language
It is well established that allogrooming, which evolved for a hygienic function, has acquired an important derived social function in many primates. In particular, it has been postulated thatExpand
Network Structure and Social Complexity in Primates
TLDR
Data is used on primate grooming networks to show that three different social grades can be differentiated in terms of network structuring, which seems to arise from a glass ceiling imposed on group size by limits on the time available for social grooming. Expand
Social complexity and the fractal structure of group size in primate social evolution
TLDR
It is argued that the grades themselves represent glass ceilings on animals' capacity to maintain social and spatial coherence during foraging and that, in order to evolve more highly bonded groups, species have to be able to invest in costly forms of cognition. Expand
Costs and benefits of group living in primates: group size effects on behaviour and demography
TLDR
It is indicated that folivores and frugivores face similar ecological pressures and the costs of living in larger groups balance or outweigh the benefits, and the effect of group size on behaviour and fitness is analyzed. Expand
The effect of social and ecological factors on the time budget of wild vervet monkeys
TLDR
The results indicate that intragroup competition may force larger groups to spend more time feeding and less time resting, and it is found that seasonal variation, and therefore food availability, has a strong influence on the monkeys’ activity budget. Expand
Analysing the effects of group size and food competition on Japanese macaque social relationships
TLDR
The results indicate that social relationships within the two groups were the result of the combination of group size differences and of the balance between the benefits and costs of a lower/greater level of inter- and intra-group food competition. Expand
Human grooming in comparative perspective: People in six small-scale societies groom less but socialize just as much as expected for a typical primate.
TLDR
It is found that human grooming may be a (recent) phylogenetic outlier when defined narrowly as parasite removal but not defined broadly as personal hygiene, and there was no support for thermoregulatory functions of grooming, and noSupport for the "vocal grooming" hypothesis of language having evolved as a less time-consuming means of bonding.

What Does Mutual Grooming Tell Us About Why Chimpanzees Groom
Grooming might be a resource that is offered in exchange for some benefit (e.g. access to a feeding site or coalitionary support) or it might be a mechanism for building and servicing socialExpand

TLDR
Field studies of spider monkeys and chimpanzees were used to test a model of ecological constraints on animal group size which suggests that group size is a function of travel costs and assess ecological and social factors underlying the social organization of these two species. Expand

TLDR
Compared the grooming interactions of adult females from four troops in the Drakensberg mountains, it is argued that females attempt to groom all other females as well as sustain closer relationships with a few females through longer bouts of reciprocated grooming, likely to facilitate fission.

A model is presented to account for the evolution of FB groups in terms of ecological pressures on female relationships and suggests that relationships in most FB groups are ultimately related to feeding competition. Expand
