Greene 2015; Tomasello and Vaish, 2013) is that moral cognition is a biological adaptation to foster social cooperation. This chapter argues, to the contrary, that moral cognition is likely an evolutionary exaptation (Gould, 1991): a form of cognition where neurobiological capacities selected for in our evolutionary history for a variety of different reasons-many unrelated to social cooperation-were put to a new, prosocial use after the fact through individual rationality, learning, and the development and transmission of social norms.My argument has three steps. First, I provide a brief overview of the emerging behavioral neuroscience of moral cognition. I then outline a theory of moral cognition that I have argued explains these findings better than alternatives (Arvan, 2020). Finally, I demonstrate how the evidence for this theory of moral cognition and human evolutionary history together suggest that moral cognition is likely not a biological adaptation. Instead, like reading sheet music or riding a bicycle, moral cognition is something that individuals learn to do-in this case, in response to sociocultural norms created in our ancestral history and passed down through the ages to enable cooperative living. This chapter thus aims to set evolutionary ethics on a new path, identifying the evolutionary function of moral cognition with a complex interplay between neurobiological and cultural evolution.
