Tolerance in intergroup encounters: "we explore how the human foraging ecology, especially large geographic & temporal fluctuations in resource availability, may have selected for greater reliance on tolerant between-community relationships" https://t.co/uaM28ayAnU

New pre-print: What are the candidate selection pressures favoring tolerance in intergroup encounters in primates? Do these give us insight into the prevalence and plasticity of tolerance in humans & non-human great apes? https://t.co/FiIhertZOA https://t.co/iogrBqpwoN

Primate individuals use a variety of strategies in intergroup encounters, from aggression to tolerance; however, recent focus on the evolution of either warfare or peace has come at the cost of characterizing this variability. We identify evolutionary advantages that may incentivize tolerance toward extra-group individuals in humans and non-human primates, including enhanced benefits in the domains of transfer, mating, and food acquisition. We highlight the role these factors play in the flexibility of gorilla, chimpanzee, bonobo, and human behavior. Given humans have an especially broad range of intergroup behavior, we explore how the human foraging ecology, especially large geographic and temporal fluctuations in resource availability, may have selected for a greater reliance on tolerant between-community relationships – relationships reinforced by status acquisition and cultural institutions. We conclude by urging careful, theoretically-motivated study of behavioral flexibility in intergroup encounters in humans and the non-human great apes.
This paper is under resubmission to Evolutionary Anthropology. The most notable changes to the revised manuscript are a greatly reduced Section 2, the most important content of which now appears in Table 1 and Box 1, and a more streamlined introduction with clarification of our claims and unique contributions. Other small changes include the further incorporation of ethnographic data into discussions of status and cultural institutions in the human section, use of the phrase “behavior flexibility” in lieu of “behavioral plasticity” throughout for clarity, removed discussion of the social brain hypothesis, and a new title.
