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
TLDR
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

TLDR
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
TLDR
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.
Reciprocity explains food sharing in humans and other primates independent of kin selection and tolerated scrounging: a phylogenetic meta-analysis
  • A. Jaeggi, M. Gurven
  • Psychology, Medicine

  • 2013
TLDR
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.
Generosity, selfishness and exploitation as optimal greedy strategies for resource sharing.
TLDR
The results show that resource sharing is favoured by three factors: a long time horizon over which the players try to optimize their own game, the similarity among players in their ability of performing the resource-gathering task, as well as by the availability of resources in the environment, which lead to identify necessary conditions for the emergence of generosity.
First report of food sharing among nicobar long-tailed macaques
TLDR
This study on Nicobar long-tailed macaques highlights some features that might make this species an ideal model to study the evolution of human behavior, and argues that the observations could support the reciprocal exchange rather than the harassment hypothesis.
The evolution of daily food sharing: A Bayesian phylogenetic analysis
Abstract Some human subsistence economies are characterized by extensive daily food sharing networks, which may buffer the risk of shortfalls and facilitate cooperative production and divisions of
Ecological rationality: Convergent decision-making in apes and capuchins
TLDR
An ecological rationality framework is used to examine patterns of decision-making across species to illuminate the origins of these strategies and argues that identifying the evolutionary pressures driving the emergence of specific decision strategies can shed light into the adaptive nature of human economic preferences.
The importance of memory for the success of cooperation under ecological adversity
TLDR
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
TLDR
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.
Chimpanzees share food for many reasons: the role of kinship, reciprocity, social bonds and harassment on food transfers
TLDR
The analyses suggest that food transfers serve multiple functions for chimpanzees, and individuals may use food transfers to enhance the welfare of closely related group members, strengthen social relationships with favoured partners and reduce the costs of persistent solicitations.

Evolutionary foundations of human prosocial sentiments
TLDR
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
TLDR
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.

Cooperation in primates and humans : mechanisms and evolution
TLDR
This work presents a general model for male-male coalitions in primate groups and investigates the role of cooperation from an economic perspective.
Social tolerance in a despotic primate: co-feeding between consortship partners in rhesus macaques.
TLDR
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.
Food sharing and reciprocal obligations among chimpanzees
Food sharing has been proposed as the propeller of hominid evolution, particularly of the development of systems of mutual social obligation. Yet, food sharing in our closest relative has never been
The evolutionary and ecological roots of human social organization
TLDR
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.
