 Another hope on the part of philosophers is that understanding the evolution of cognition might give us some insight into the nature of certain human psychological traits that have particular philosophical interest. One such trait is our moral psychology. Moral psychology is of interest to philosophers who hold naturalistic views of ethics because they believe moral values depend in part on features of that psychology; understanding that psychology and how it evolved would give us insight into what the correct moral values are. Understanding the origins of human moral psychology might also help answer certain metaethical questions (Street, 2006). As Wilson hoped, scientists working in disciplines which are the modern descendants of sociobiology have contributed to our understanding of the way that norms, including moral norms, might have become established in human evolution (see, for example, Henrich and Boyd, 2001; Sripada, 2005). Philosophers still strongly disagree, however, on how the evolution of moral psychology, especially for the acquisition of norms, should be understood (Dwyer, 2006; Sripada and Stich, 2006; Sterelny, 2010).
