Evolutionary psychologists seek to understand psychological traits and behaviours by understanding the survival and reproductive functions they might have served over the course of evolutionary history, and the advantages that they may have conferred on the species. These ‘adaptations’ might include abilities to infer others' emotions (empathy), identify, prefer and establish relationships with partners, cooperate with others, act morally etc. Evolutionary psychology recognizes the role of natural selection and cultural evolution in developing prosocial traits such as altruism, large scale cooperation and community mindedness.
