The theory of reciprocal altruism offers an explanation for the evolution of altruistic behaviours among unrelated animals. Among primates, grooming is one of the most common altruistic behaviours. Primates have been suggested to exchange grooming both for itself and for rank-related benefits. While previous meta-analyses have shown that they direct their grooming up the hierarchy and exchange it for agonistic support, no comprehensive evaluation of grooming reciprocation has been made. Here we… Expand

Development of studies on grooming reciprocity in primates
Many researchers have investigated why and how animals benefit from each other in a group. Grooming is considered as prosocial behavior in animal societies; the groomer expends time and energy costs,Expand
From Grooming to Giving Blood: The Origins of Human Altruism
The human capacities for culture may have created novel evolutionary forces that altered the selective benefits derived from cooperation, and cooperation in human societies may also be supported by group-level processes that do not exist in other primate species. Expand
Chapter 2 Reciprocal Altruism in Primates
Abstract This paper reviews recent work on reciprocal altruism in primates with the aim of highlighting the roles that reciprocal partner choice may have had in the evolution of primate altruism, andExpand
The relative roles of kinship and reciprocity in explaining primate altruism.
The results of a direct test comparing the relative roles of kinship and reciprocity in explaining animal altruism based on a meta-analysis of allogrooming in primates suggest that reciprocity played a much larger role than kinship in explaining primate allogsrooming. Expand
Emergent Patterns of Social Affiliation in Primates, a Model
An individual-based model with a high potential for self-organisation is used as a null model to increase the understanding of affiliative behaviour among primates, in particular macaques. Expand
Whom to Groom and for What? Patterns of Grooming in Female Barbary Macaques (Macaca sylvanus)
Grooming was more frequent among individuals with higher friendship values as well as amongst related individuals, and the reciprocation of grooming was a significant predictor of grooming interactions between individuals of similar rank, but not between those individuals more distantly separated in the social hierarchy.

This study is the first to use meta-analyses to quantify the effects on human helping and to directly compare humans and other primates, finding similar effect sizes in humans and primates speak against cognitive constraints on reciprocity. Expand
Social dominance and cooperation in female vampire bats
It is found no evidence that females groomed or shared food up a hierarchy or that differences in rank explained asymmetries in grooming or food sharing, and a weakly linear dominance hierarchy was found using three common metrics. Expand
Correlated pay-offs are key to cooperation
It is found that neither the cognitive requirements of reciprocal cooperation nor the often sequential nature of interactions are insuperable stumbling blocks for the evolution of reciprocity. Expand
Reciprocation and interchange of grooming, agonistic support, feeding tolerance, and aggression in semi‐free‐ranging Barbary macaques
This article is the first to explore the reciprocation and interchange of grooming in the Barbary macaque (Macaca sylvanus) and will facilitate comparative analyses of exchange behavior by adding to the current database a new species, characterized by a different social style from those macaque species previously investigated.

Grooming and agonistic support: a meta-analysis of primate reciprocal altruism
Findings suggest that grooming and agonistic support may have evolved as part of a system of low-cost reciprocal altruism, and highlight the potential of meta-analysis in tackling the study of behavioral phenomena characterized by low overall frequency and small effect sizes. Expand
Grooming, alliances and reciprocal altruism in vervet monkeys
The field experiments on vervet monkeys are demonstrated to demonstrate that grooming between unrelated individuals increases the probability that they will subsequently attend to each others' solicitations for aid. Expand
Grooming, competition and social rank among female primates: a meta-analysis
Abstract Seyfarth (1977, Journal of Theoretical Biology,65, 671–698) proposed a model of social grooming among female monkeys that has had an enormous influence in the primatological literature. ToExpand
The value of grooming to female primates
This work presents a new framework in which the inconsistencies regarding grooming and relationship negotiation are interpreted in the context of individual decision-making processes and indicates the need for socioecological studies to focus on the dynamics of individual relationships rather than using summary measures. Expand
Reciprocal food sharing in the vampire bat
It is shown that food sharing by regurgitation of blood among wild vampire bats (Desmodus rotundus) depends equally and independently on degree of relatedness and an index of opportunity for recipro cation. Expand
Grooming and coalitions in Japanese macaques (Macaca fuscata): partner choice and the time frame reciprocation.
A large database of grooming and coalitions in captive female Japanese macaques (Macaca fuscata) was analyzed to investigate their within-group distribution and temporal relations, and the proximate mechanisms underlying the exchange of services were discussed in relation to the time frame of the behavioral choices made by the monkeys.

Market forces predict grooming reciprocity in female baboons
We argue that grooming is a commodity that female primates can trade, either for itself or in exchange for other services (sensu biological markets theory) and that the decision to do either willExpand
Time-matched grooming in female primates? New analyses from two species
Abstract The parcelling model of reciprocity predicts that grooming partners will alternate between giving and receiving grooming within grooming bouts, and that each partner will performExpand

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in theExpand
Reciprocity of support in coatis (Nasua nasua).
The authors found that support in aggressive conflicts is a common feature in coatis and that this behavior is reciprocally exchanged in a manner seemingly as complex as in primates. Expand
