Humans routinely classify others according to both their individual attributes, such as social status or wealth, and membership in higher order groups, such as families or castes. They also recognize that people's individual attributes may be influenced and regulated by their group affiliations. It is not known whether such rule-governed, hierarchical classifications are specific to humans or might also occur in nonlinguistic species. Here we show that baboons recognize that a dominance… Expand

Simultaneous classification by rank and kinship in Japanese macaques
To assess evidence of the ability of Japanese macaques, Macaca fuscata, to recognize the rank and kin relationships of other individuals, we analysed the recruitment of allies in the context ofExpand
A Biosocial Model of Status in Face-To-Face Groups
Allocation and maintenance of rank in status hierarchies of human face-to-face groups are in many ways similar to what is observed in dominance hierarchies of other primates, especially in speciesExpand
Pinyon jays use transitive inference to predict social dominance
It is shown that highly social pinyon jays (Gymnorhinus cyanocephalus) draw sophisticated inferences about their own dominance status relative to that of strangers that they have observed interacting with known individuals, demonstrating that animals use transitive inference in social settings and implying that such cognitive capabilities are widespread among social species. Expand
Ravens notice dominance reversals among conspecifics within and outside their social group
It is shown that ravens react differently to playbacks of dominance interactions that either confirm or violate the current rank hierarchy of members in their own social group and of ravens in a neighbouring group, suggesting thatRavens understand third-party relations and may deduce those not only via physical interactions but also by observation.

How life in a tolerant society affects the attention to social information in baboons
An animals' ability to classify relationships between conspecifics according to kinship, affiliation and dominance constitutes an important adaptation to life in social groups. Yet, variation in theExpand
Social intelligence in the spotted hyena (Crocuta crocuta)
Spotted hyenas appear to rely more intensively than primates on social facilitation and simple rules of thumb in social decision making, and the gross anatomy of the brain in spotted Hyenas might resemble that in primates with respect to expansion of frontal cortex, presumed to be involved in the mediation of social behaviour. Expand
Patterns of alliance formation and postconflict aggression indicate spotted hyaenas recognize third-party relationships
The social complexity hypothesis posits that natural selection has favoured the evolution of intelligence in animals living in challenging social environments. Although several primate species haveExpand
Social feedback and the emergence of rank in animal society
A new theory is presented, of a feedback loop between knowledge of rank and consequent behavior, that explains the transition to strategic aggression, and the formation and persistence of dominance hierarchies in groups capable of both social memory and social inference. Expand
Human Identity and the Evolution of Societies
It is proposed that the human brain has evolved to permit not only the close relationships described by the social brain hypothesis, but also, at little mental cost, the anonymous societies within which such alliances are built. Expand
Social Relationships, Social Cognition, and the Evolution of Mind in Primates
During the past 20 years, research on cognition in primates and other animals has shifted from the laboratory to the field—from studies of animals' knowledge of objects to research on what they knowExpand


Recognition of other individuals’ social relationships by female baboons
Results indicate that female baboons recognize the screams and threat grunts of their own close relatives but also of unrelated individuals, and replicate previous studies in suggesting that female monkeys recognize the close associates of other individuals and adjust their interactions with others according to recent events involving individuals other than themselves.

It is shown that male bonnet macaques, Macaca radiata, use information about third-party rank relationships when they recruit support from other males, and consistently chose allies that outranked themselves and their opponents. Expand
Rank Maintenance in Female Japanese Macaques: Experimental Evidence for Social Dependency
In many species of cercopithecines characterized by a matrilineal dominance system, a female inherits her mother's rank (genealogical rank) and there is no correlation between a female's genealogicalExpand
The effects of maternal kinship, reciprocity, and dominance rank on the social relationships of female baboons in a well-habituated, free-ranging group in the Okavango Delta of Botswana are examined. Expand

The nature of knowledge acquired by bonnet macaque females may be egotistical in that other individuals are evaluated relative to oneself, integrative in that information about all other interactants is used simultaneously, and hierarchical in the ability to preferentially use certain categories of knowledge for the storage of related information from other domains.

Kin-oriented redirection among Japanese macaques: an expression of a revenge system?
Abstract The ability to recognize the close associates of other group members may permit the display of redirected aggression against the relatives of the former aggressor. However, the dominanceExpand
Continuity and change in dominance relations among female baboons
Female baboons, Papio cynocephalus, in Amboseli National Park establish linear dominance hierarchies in which maternal kin usually occupy adjacent ranks, and data from the 15-year period suggest that the rates of change in female dominance relations are variable. Expand
Vocal recognition of individuals and kin in free-ranging rhesus monkeys
The social behaviour of many species of non-human primates suggests a capacity for both individual and kin recognition. In these species, the ability to signal and perceive identity at a distance mayExpand
A social concept in Java monkeys
Abstract Two adult female Java monkeys, Macaca fascicularis, demonstrated their ability to form a concept of affiliation by their choices of slides of group members. In a discrimination task, oneExpand
Long-Term Consistency of Dominance Relations Among Female Baboons (Papio cynocephalus)
At maturity, female baboons in the Amboseli National Park of Kenya generally attain a rank position among adults near to that of their mothers. However, the age of a female's mother and theExpand
