	Title	A century of getting to know the chimpanzee			Type	Journal Article
	Year	2005	Publication	Nature	Abbreviated Journal	Nature
	Volume	437	Issue	7055	Pages	56-59
	Keywords	Aggression; Animals; Behavior, Animal/physiology; Competitive Behavior; Cooperative Behavior; Female; Humans; Male; Pan troglodytes/genetics/physiology/psychology; Sexual Behavior, Animal; *Social Behavior
	Abstract	A century of research on chimpanzees, both in their natural habitat and in captivity, has brought these apes socially, emotionally and mentally much closer to us. Parallels and homologues between chimpanzee and human behaviour range from tool-technology and cultural learning to power politics and intercommunity warfare. Few behavioural domains have remained untouched by this increased knowledge, which has dramatically challenged the way we view ourselves. The sequencing of the chimpanzee genome will no doubt bring more surprises and insights. Humans do occupy a special place among the primates, but this place increasingly has to be defined against a backdrop of substantial similarity.

	Title	Conformity to cultural norms of tool use in chimpanzees			Type	Journal Article
	Year	2005	Publication	Nature	Abbreviated Journal	Nature
	Volume	437	Issue	7059	Pages	737-740
	Keywords	Aging/physiology; Animals; Culture; Feeding Behavior/physiology; Female; Pan troglodytes/physiology/psychology; *Social Conformity; Technology; Time Factors
	Abstract	Rich circumstantial evidence suggests that the extensive behavioural diversity recorded in wild great apes reflects a complexity of cultural variation unmatched by species other than our own. However, the capacity for cultural transmission assumed by this interpretation has remained difficult to test rigorously in the field, where the scope for controlled experimentation is limited. Here we show that experimentally introduced technologies will spread within different ape communities. Unobserved by group mates, we first trained a high-ranking female from each of two groups of captive chimpanzees to adopt one of two different tool-use techniques for obtaining food from the same 'Pan-pipe' apparatus, then re-introduced each female to her respective group. All but two of 32 chimpanzees mastered the new technique under the influence of their local expert, whereas none did so in a third population lacking an expert. Most chimpanzees adopted the method seeded in their group, and these traditions continued to diverge over time. A subset of chimpanzees that discovered the alternative method nevertheless went on to match the predominant approach of their companions, showing a conformity bias that is regarded as a hallmark of human culture.

	Title	The second inheritance system of chimpanzees and humans			Type	Journal Article
	Year	2005	Publication	Nature	Abbreviated Journal	Nature
	Volume	437	Issue	7055	Pages	52-55
	Keywords	Animals; Animals, Wild/physiology/psychology; Behavior, Animal/physiology; Culture; Female; Humans; Imitative Behavior; Learning/physiology; Pan troglodytes/physiology/psychology; *Social Behavior; Technology
	Abstract	Half a century of dedicated field research has brought us from ignorance of our closest relatives to the discovery that chimpanzee communities resemble human cultures in possessing suites of local traditions that uniquely identify them. The collaborative effort required to establish this picture parallels the one set up to sequence the chimpanzee genome, and has revealed a complex social inheritance system that complements the genetic picture we are now developing.

	Title	Monkeys reject unequal pay			Type	Journal Article
	Year	2003	Publication	Nature	Abbreviated Journal	Nature
	Volume	425	Issue	6955	Pages	297-299
	Keywords	Aging; Animals; Cebus/psychology; Choice Behavior; Cooperative Behavior; Female; Male; *Reward; Social Justice
	Abstract	During the evolution of cooperation it may have become critical for individuals to compare their own efforts and pay-offs with those of others. Negative reactions may occur when expectations are violated. One theory proposes that aversion to inequity can explain human cooperation within the bounds of the rational choice model, and may in fact be more inclusive than previous explanations. Although there exists substantial cultural variation in its particulars, this 'sense of fairness' is probably a human universal that has been shown to prevail in a wide variety of circumstances. However, we are not the only cooperative animals, hence inequity aversion may not be uniquely human. Many highly cooperative nonhuman species seem guided by a set of expectations about the outcome of cooperation and the division of resources. Here we demonstrate that a nonhuman primate, the brown capuchin monkey (Cebus apella), responds negatively to unequal reward distribution in exchanges with a human experimenter. Monkeys refused to participate if they witnessed a conspecific obtain a more attractive reward for equal effort, an effect amplified if the partner received such a reward without any effort at all. These reactions support an early evolutionary origin of inequity aversion.

	Title	Social intelligence in the spotted hyena (Crocuta crocuta)			Type	Journal Article
	Year	2007	Publication	Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences	Abbreviated Journal	Philos Trans R Soc Lond B Biol Sci
	Volume	362	Issue	1480	Pages	523-538
	Keywords	Anatomy, Comparative; Animals; Brain/anatomy & histology; Cercopithecinae/anatomy & histology/physiology; Decision Making/physiology; Hyaenidae/anatomy & histology/physiology; Intelligence; Recognition (Psychology); Social Behavior; Species Specificity
	Abstract	If the large brains and great intelligence characteristic of primates were favoured by selection pressures associated with life in complex societies, then cognitive abilities and nervous systems with primate-like attributes should have evolved convergently in non-primate mammals living in large, elaborate societies in which social dexterity enhances individual fitness. The societies of spotted hyenas are remarkably like those of cercopithecine primates with respect to size, structure and patterns of competition and cooperation. These similarities set an ideal stage for comparative analysis of social intelligence and nervous system organization. As in cercopithecine primates, spotted hyenas use multiple sensory modalities to recognize their kin and other conspecifics as individuals, they recognize third-party kin and rank relationships among their clan mates, and they use this knowledge adaptively during social decision making. However, hyenas appear to rely more intensively than primates on social facilitation and simple rules of thumb in social decision making. No evidence to date suggests that hyenas are capable of true imitation. Finally, it appears that 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.

	Title	Knowledge acquired and decisions made: triadic interactions during allogrooming in wild bonnet macaques, Macaca radiata			Type	Journal Article
	Year	1998	Publication	Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences	Abbreviated Journal	Philos Trans R Soc Lond B Biol Sci
	Volume	353	Issue	1368	Pages	619-631
	Keywords	Aggression; Animals; Cognition; Computer Simulation; Decision Making; Evolution; Female; Grooming; Logistic Models; Macaca radiata/psychology; Social Behavior; Social Dominance
	Abstract	The pressures of developing and maintaining intricate social relationships may have led to the evolution of enhanced cognitive abilities in many nonhuman primates. Knowledge of the dominance ranks and social relationships of other individuals, in particular, is important in evaluating one's position in the rank hierarchy and affiliative networks. Triadic interactions offer an excellent opportunity to examine whether decisions are taken by individuals on the basis of such knowledge. Allogrooming supplants among wild female bonnet macaques (macaca radiata) usually involved the subordinate female of a grooming dyad retreating at the approach of a female dominant to both members of the dyad. In a few exceptional cases, however, the dominant member of the dyad retreated; simple non-cognitive hypotheses involving dyadic rank differences and agonistic relationships failed to explain this phenomenon. Instead, retreat by the dominant individual was positively correlated with the social attractiveness of her subordinate companion (as measured by the duration of grooming received by the latter from other females in the troop). This suggests that not only does an individual evaluate relationships among other females, but does so on the basis of the amount of grooming received by them. Similarly, the frequency of approaches received by any female was correlated with her social attractiveness when she was the dominant member of the dyad, but not when she was the subordinate. This indicated that approaching females might be aware of the relative dominance ranks of the two allogrooming individuals. In logistic regression analyses, the probability of any individual retreating was found to be influenced more by her knowledge of her rank difference with both the other interactants, rather than by their absolute ranks. Moreover, information about social attractiveness appeared to be used in terms of correlated dominance ranks. The nature of knowledge acquired by bonnet macaque females may thus 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.

	Title	Teaching in wild meerkats			Type	Journal Article
	Year	2006	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	313	Issue	5784	Pages	227-229
	Keywords	Animals; Animals, Wild/psychology; Behavior, Animal; Herpestidae/psychology; Learning; Predatory Behavior; South Africa; *Teaching; Vocalization, Animal
	Abstract	Despite the obvious benefits of directed mechanisms that facilitate the efficient transfer of skills, there is little critical evidence for teaching in nonhuman animals. Using observational and experimental data, we show that wild meerkats (Suricata suricatta) teach pups prey-handling skills by providing them with opportunities to interact with live prey. In response to changing pup begging calls, helpers alter their prey-provisioning methods as pups grow older, thus accelerating learning without the use of complex cognition. The lack of evidence for teaching in species other than humans may reflect problems in producing unequivocal support for the occurrence of teaching, rather than the absence of teaching.
