Cooperation is needed for evolution to construct new levels of organization. Genomes, cells,
multicellular organisms, social insects, and human society are all based on cooperation …

We propose that the crucial difference between human cognition and that of other species is
the ability to participate with others in collaborative activities with shared goals and …

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the
wild, often failing to overcome even basic challenges, like obtaining food, building shelters …

Oxford presents, in one convenient and coherently organized volume, 20 influential but until
now relatively inaccessible articles that form the backbone of Boyd and Richerson's path …

Both laboratory and field data suggest that people punish noncooperators even in one-shot
interactions. Although such “altruistic punishment” may explain the high levels of …

Large-scale societies in which strangers regularly engage in mutually beneficial
transactions are puzzling. The evolutionary mechanisms associated with kinship and …

Recent behavioral experiments aimed at understanding the evolutionary foundations of
human cooperation have suggested that a willingness to engage in costly punishment, even …

Human cooperation is highly unusual. We live in large groups composed mostly of non-
relatives. Evolutionists have proposed a number of explanations for this pattern, including …

The scale of human cooperation is an evolutionary puzzle. All of the available evidence
suggests that the societies of our Pliocene ancestors were like those of other social …

Contemporary humans exhibit spectacular biological success derived from cumulative
culture and cooperation. The origins of these traits may be related to our ancestral group …
