The study of cooperation is rich with theoretical models and laboratory experiments that have greatly advanced our knowledge of human uniqueness, but have sometimes lacked ecological validity. We therefore emphasize the need to tie discussions of human cooperation to the natural history of our species and its closest relatives, focusing on behavioral contexts best suited to reveal underlying selection pressures and evolved decision rules. Food sharing is a fundamental form of cooperation that… 

27. Food altruism in human beings: facts and factors

This paper examines some of the behaviours that society defines as beneficial to others, with special reference to food altruism (food sharing), and considers that prosocial tendencies exist in humans because the authors are genetically predisposed to act prosocially.

Food‐Sharing Models

Food sharing is one of the most obvious forms of cooperation among hunter-gatherers and is intricately linked to the evolved human life history and foraging niche; it is also observed in other

The evolution of altruistic social preferences in human groups

Three hypotheses are considered to account for the evolution of the extraordinary capacity for large-scale cooperation and altruistic social preferences within human societies: human cooperation is built on the same evolutionary foundations as cooperation in other animal societies, fundamental elements of the social preferences that shape the authors' species' cooperative behaviour are also shared with other closely related primates.

Social bonds facilitate cooperative resource sharing in wild chimpanzees

It is concluded that the emotional connection inherent in social bonds was a key factor determining sharing patterns, with the oxytocinergic system potentially facilitating long-term cooperative exchanges in chimpanzees.

This study is the first to use meta-analyses to quantify the effects on human helping and to directly compare humans and other primates, finding similar effect sizes in humans and primates speak against cognitive constraints on reciprocity.

It is shown that in a society under ecological pressure, the reciprocity network permitted by collaborative memory promotes cooperation.

The evolution of food sharing in primates

Comparisons provide comparative support for the hypothesis that sharing is “traded” for matings and coalitionary support in the sense that these services are statistically associated and can thus be selected for.

Evolutionary foundations of human prosocial sentiments

There may be fundamental differences in the social preferences that motivate altruism across the primate order, and a body of experimental studies designed to examine the phylogenetic range of prosocial sentiments and behavior is beginning to shed some light on this issue.

On the psychology of cooperation in humans and other primates: combining the natural history and experimental evidence of prosociality

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.

Social tolerance in a despotic primate: co-feeding between consortship partners in rhesus macaques.

The results suggest that co-feeding is possible even in the most despotic of primate species, but perhaps only in contexts that specifically promote the necessary social tolerance.

The evolutionary and ecological roots of human social organization

This paper presents an explanatory framework for understanding variation in social organization across human societies, highlighting the interactive effects of four key ecological and economic variables: the role of skill in resource production; the degree of complementarity in male and female inputs into production; economies of scale in cooperative production and competition; and the economic defensibility of physical inputs intoProduction.
