Social grooming and coalition formation have been main foci in studies concerning altruism in monkeys. Results have been inconclusive because the altruistic nature of these behaviors remains unclear. I investigated altruism in a more transparent context via an apparatus in which captive long-tailed macaque females had the choice to exploit a food source themselves or to yield the food to a test partner. I hypothesized that if potential donors behaved altruistically toward kin, they would yield… 
Neither kin selection nor familiarity explain affiliative biases towards maternal siblings in wild mountain gorillas
Evolutionary theories predict that sibling relationships will reflect a complex balance of cooperative and competitive dynamics. In most mammals, dispersal and death patterns mean that sibling
Long-tailed macaques: an unfairness model for humans
TLDR
It is suggested that the aversion observed in this species was associated with the degree of preference for the outcome (food type) offered rather than the distribution ratio, which could bring this species into irrationality.
Mechanisms influencing friendship in chimpanzees (Pan troglodytes): Kinship, familiarity or personality trait similarity?
TLDR
It is concluded that chimpanzees show friendships, and similar kinship and kin recognition mechanisms operate in their formation and maintenance as those in human friendships.
Group service in macaques (Macaca fuscata), capuchins (Cebus apella) and marmosets (Callithrix jacchus): a comparative approach to identifying proactive prosocial motivations.
TLDR
The results are consistent with the cooperative breeding hypothesis, and a comprehensive evaluation requires adding data from additional groups and species, which should be facilitated by the group service approach.
'Friendship' in Macaques : economics and emotions
TLDR
When biologists and social scientist describe close bond among monkeys and humans, they describe the same homologue phenomenon, and the use of the term friendship for animals, therefore, seems justified.
On the psychology of cooperation in humans and other primates: combining the natural history and experimental evidence of prosociality
TLDR
The comparison suggests that humans share with their closest living relatives reactive responses to signals of need, but differ in sensitivity to signs of need and cues of being watched, as well as in the presence of proactive prosociality.
Prosocial behaviour in animals: the influence of social relationships, communication and rewards
The microbiota-gut-brain axis: neurobehavioral correlates, health and sociality
TLDR
Evidence on the ability of the gut microbiota to communicate with the brain and thus modulate behavior is reviewed, and ethological and cultural strategies of human and non-human primates to select, transfer and eliminate microorganisms for selecting the commensal profile are elaborate.

Fight interference and altruism in rhesus monkeys
TLDR
Fight interference data from a group of free-ranging rhesus monkeys used to test hypotheses about the evolution and importance of altruism suggest that the survival value and thus evolution of interference behavior involves factors acting through both the social and genetic levels of organization.
Development of partner preferences in Japanese Macaques (Macaca fuscata): Effects of gender and kinship during the second year of life
TLDR
It is concluded that sex differences in behavioral frequencies become evident during the first year of life, andsex differences in partner preferences emerge during the second year oflife.

Kin and non-kin interventions in the aggressive disputes of vervet monkeys
TLDR
Interventions in aggressive disputes were investigated in a free-living troop of vervets in Barbados, suggesting that reciprocation is a necessary component of non-kin interventions and the implications for the evolution of kin and reciprocal altruism were discussed.
Altruism Among Female Macaca Radiata: Explanations and Analysis of Patterns of Grooming and Coalition Formation
TLDR
Analysis of the observed patterns of two forms of putative altruism among adult female members of a group of captive bonnet macaques (Macaca radiata) indicates that both kinship and dominance rank influence the distribution and rate of these behaviors.
Interindividual distance and influence of dominance on feeding in a natural Japanese macaque troop
In a natural troop of Japanese macaques (Macaca fuscata yakui), the dominant-subordinate relationship restricted the feeding behavior of the subordinate in two ways: (1) the dominant drives away the

TLDR
An analysis of aiding behavior in a group of 49 pigtail macaques demonstrated that these animals were very selective in the performance of these aids, and chose to aid relatives of a closer degree of relatedness more often than relatives more distantly related.
The social regulation of population density and age-sex distribution in the toque monkey
TLDR
As a consequence of these behaviorally imposed feeding efficiencies, young animals died at greater rates than adults, and infant and juvenile females died at greatest rates than their male peers; behaviorally mediated access to other resources is likely to influence mortality in a similar manner.
