Abstract

Are humans genetically predisposed to exhibit prosocial behaviours? Elliott Sober and David Sloan Wilson have made major contributions to our understanding of this question. In my remarks here I will propose a revision in their definition of altruism, suggest a broader term, ‘prosociality', to account for cooperation in humans, and present evidence for a particular set of human prosocial traits that likely evolved with our species and may account for our unique ability to maintain intricate cooperative networks not based on ties of kinship
