Modern theories of the evolution human cooperation focus mainly on altruism. In contrast, we propose that humans’ species-unique forms cooperation—as well as their cognition, communication, and social life—all derive from mutualistic collaboration (with selection against cheaters). a first step, humans became obligate collaborative foragers such individuals were interdependent with one another so had direct interest in well-being partners. this context, they evolved new skills motivations...
Humans collaborate with non-kin in special ways, but the evolutionary foundations of these collaborative skills remain unclear. We presented chimpanzees collaboration problems which they had to decide when recruit a partner and potential recruit. In an initial study, individuals recruited collaborator only solving problem required collaboration. second more effective two partners on basis their experience each them previous day. Therefore, recognizing is necessary determining who best are...
People often act on behalf of others. They do so without immediate personal gain, at cost to themselves, and even toward unfamiliar individuals. Many researchers have claimed that such altruism emanates from a species-unique psychology not found in humans' closest living evolutionary relatives, as the chimpanzee. In favor this view, few experimental studies chimpanzees produced mostly negative results. contrast, we report evidence perform basic forms helping absence rewards spontaneously...
Egalitarian behavior is considered to be a species-typical component of human cooperation. Human adults tend share resources equally, even if they have the opportunity keep larger portion for themselves. Recent experiments suggested that this tendency emerges fairly late in ontogeny, not before 6 or 7 years age. Here we show 3-year-old children mostly equally with peer after worked together actively obtain rewards collaboration task, when those could easily monopolized. These findings...
Chimpanzees (Pan troglodytes) competed with a human for food. The sat inside booth, 1 piece of food to her left and right, which she could retract from chimpanzee competitor's reach as needed. In Experiment 1, chimpanzees approach either side the booth unseen but then had through 2 tunnels (1 clear, opaque) 2, both were clear was looking away, made loud noise when it opened. preferentially reached opaque tunnel in first study silent second, successfully concealing their taking competitor...
Chimpanzees ( Pan troglodytes ) sometimes help both humans and conspecifics in experimental situations which immediate selfish benefits can be ruled out. However, several experiments, chimpanzees have not provided food to a conspecific even when it would cost them nothing, leading the hypothesis that prosociality food-provisioning context is derived trait humans. Here, we show obtain non-food items—given donor cannot get herself. Furthermore, key factor eliciting chimpanzees' targeted...
Inferring the evolutionary history of cognitive abilities requires large and diverse samples. However, such samples are often beyond reach individual researchers or institutions, studies limited to small numbers species. Consequently, methodological site-specific-differences across can limit comparisons between Here we introduce ManyPrimates project, which addresses these challenges by providing a large-scale collaborative framework for comparative in primate cognition. To demonstrate...
Many animal species cooperate, but the underlying proximate mechanisms are often unclear. We presented chimpanzees with a mutualistic collaborative food-retrieval task requiring complementary roles, and tested subjects' ability to help their partner perform her role. For each role, subjects required different tool, tools were not interchangeable. gave one individual in dyad both tools, measured willingness transfer tool as well which (correct versus incorrect) they transferred. Most helped...
Long-term collaborative relationships require that any jointly produced resources be shared in mutually satisfactory ways. Prototypically, this sharing involves partners dividing up simultaneously available resources, but sometimes the collaboration makes a resource to only one individual, and of must take place across repeated instances over time. Here, we show beginning at 5 years age, human children stabilize cooperation such cases by taking turns obtaining resource. In contrast,...
Abstract Human adults often show a preference for scarce over abundant goods. In this paper, we investigate whether was shared by 4‐ and 6‐year‐old children as well chimpanzees, humans’ nearest primate relative. Neither chimpanzees nor 4‐year‐olds displayed scarcity preference, but 6‐year‐olds did, especially in the presence of competitors. We conclude that is human‐unique develops humans increase their cognitive skills social experiences with peers explore different potential psychological...
Successful collaboration often relies on individuals' capacity to communicate with each other. Despite extensive research chimpanzee communication, there is little evidence that chimpanzees are capable, without human training, of regulating collaborative activities via communication. This study investigated whether pairs were capable communicating ensure coordination during problem-solving. The needed two tools extract fruits from an apparatus. communicator in pair could see the location...
Reputation formation is a key component in the social interactions of many animal species. An evaluation reputation drawn from two principal sources: direct experience an individual and indirect observing that interacting with third party. In current study we investigated whether dogs use and/or to choose between human interactants. first experiment, subjects had interaction either "nice" (who played with, talked stroked dog) or "ignoring" experimenter who ignored dog completely. Results...
We presented small groups of chimpanzees with two collective action situations, in which was necessary for reward but there a disincentive individuals to act owing the possibility free-riding on efforts others. found that simpler scenarios (experiment 1) group size small, positive relationship between rank and more dominant volunteering often, particularly when less dispersed. Social tolerance also seemed mediate whereby higher levels within resulted lower ranks sometimes acting...
