	Title	Primates--A natural heritage of conflict resolution			Type	Journal Article
	Year	2000	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	289	Issue	5479	Pages	586-590
	Keywords	Aggression/psychology; Animals; Behavior, Animal; Conflict (Psychology); Female; Humans; Male; Primates; Social Behavior; Social Dominance
	Abstract	The traditional notion of aggression as an antisocial instinct is being replaced by a framework that considers it a tool of competition and negotiation. When survival depends on mutual assistance, the expression of aggression is constrained by the need to maintain beneficial relationships. Moreover, evolution has produced ways of countering its disruptive consequences. For example, chimpanzees kiss and embrace after fights, and other nonhuman primates engage in similar “reconciliations.” Theoretical developments in this field carry implications for human aggression research. From families to high schools, aggressive conflict is subject to the same constraints known of cooperative animal societies. It is only when social relationships are valued that one can expect the full complement of natural checks and balances.

	Title	Whistle matching in wild bottlenose dolphins (Tursiops truncatus)			Type	Journal Article
	Year	2000	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	289	Issue	5483	Pages	1355-1357
	Keywords	Animals; Animals, Wild/physiology; Dolphins/physiology; Imitative Behavior; Learning; Social Behavior; *Vocalization, Animal
	Abstract	Dolphin communication is suspected to be complex, on the basis of their call repertoires, cognitive abilities, and ability to modify signals through vocal learning. Because of the difficulties involved in observing and recording individual cetaceans, very little is known about how they use their calls. This report shows that wild, unrestrained bottlenose dolphins use their learned whistles in matching interactions, in which an individual responds to a whistle of a conspecific by emitting the same whistle type. Vocal matching occurred over distances of up to 580 meters and is indicative of animals addressing each other individually.

	Title	Effects of helpers on juvenile development and survival in meerkats			Type	Journal Article
	Year	2001	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	293	Issue	5539	Pages	2446-2449
	Keywords	Animals; Breeding; Carnivora/growth & development/physiology; Cooperative Behavior; Feeding Behavior; Female; Male; Survival Rate; *Weight Gain
	Abstract	Although breeding success is known to increase with group size in several cooperative mammals, the mechanisms underlying these relationships are uncertain. We show that in wild groups of cooperative meerkats, Suricata suricatta, reductions in the ratio of helpers to pups depress the daily weight gain and growth of pups and the daily weight gain of helpers. Increases in the daily weight gain of pups are associated with heavier weights at independence and at 1 year of age, as well as with improved foraging success as juveniles and higher survival rates through the first year of life. These results suggest that the effects of helpers on the fitness of pups extend beyond weaning and that helpers may gain direct as well as indirect benefits by feeding pups.

	Title	Public information and breeding habitat selection in a wild bird population			Type	Journal Article
	Year	2002	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	297	Issue	5584	Pages	1168-1170
	Keywords	Animal Migration; Animals; Animals, Wild/physiology; Behavior, Animal; Cognition; Cues; Environment; Female; Male; Nesting Behavior; Probability; Reproduction; Songbirds/physiology; Sweden
	Abstract	According to the “public information” hypothesis, some animal species may monitor the current reproductive success of conspecifics to assess local habitat quality and to choose their own subsequent breeding site. To test this hypothesis experimentally, we manipulated two components of public information, the mean number of offspring raised locally (“quantity”) and their condition (“quality”), in the collared flycatcher Ficedula albicollis. Immigration rate decreased with local offspring quantity but did not depend on local offspring quality, suggesting that immigrants are deprived of information regarding local quality. Conversely, emigration rate increased both when local offspring quantity or quality decreased, suggesting that residents can use both components of public information.

	Title	The domestication of social cognition in dogs			Type	Journal Article
	Year	2002	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	298	Issue	5598	Pages	1634-1636
	Keywords	Animals; Animals, Domestic; Behavior, Animal; Cognition; Cues; Dogs; Food; Humans; Memory; Pan troglodytes; Social Behavior; Species Specificity; Vision; Wolves
	Abstract	Dogs are more skillful than great apes at a number of tasks in which they must read human communicative signals indicating the location of hidden food. In this study, we found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills. These findings suggest that during the process of domestication, dogs have been selected for a set of social-cognitive abilities that enable them to communicate with humans in unique ways.

	Title	Hierarchical classification by rank and kinship in baboons			Type	Journal Article
	Year	2003	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	302	Issue	5648	Pages	1234-1236
	Keywords	Animals; Animals, Wild; Botswana; Cognition; Family; Female; Hierarchy, Social; Language; *Papio/psychology; Social Dominance; Vocalization, Animal
	Abstract	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 hierarchy can be subdivided into family groups. In playback experiments, baboons respond more strongly to call sequences mimicking dominance rank reversals between families than within families, indicating that they classify others simultaneously according to both individual rank and kinship. The selective pressures imposed by complex societies may therefore have favored cognitive skills that constitute an evolutionary precursor to some components of human cognition.
