Data simulations of Burkart et al. 2014_The evolutionary origin of human hyper-cooperation Universiteit Antwerpen
Burkart et al. conducted phylogenetic regression analyses to investigate the evolutionary drivers of proactive prosociality. They tested 24 groups of 15 primate species, including humans, in a group-service paradigm, which provided the option to any member in the group to deliver a valuable food resource to group members – the provider could not benefit themselves. Within the sample, 4 species were assayed with several groups (range groups: 2-5) and 11 species were assayed with only 1 group. In their primary regression analyses, the authors averaged prosociality scores across groups (within ...
