 In the final phase, this sort of “proto-morality” of norms and reactive emotions would then be supplemented over thousands of years with various paths of  cultural evolution,  leading to the development and fleshing out of the much more sophisticated systems of moral beliefs, practices and institutions with which we are familiar, from the earliest historical examples right up to our present moral cultures (Kitcher 2006a, 2011). There is, of course, a great deal of leeway in the last part, concerning the details of the transition through cultural evolution from hominin proto-moralities to contemporary moral systems, which allows for some very different possible stories. Some accounts will attribute great influence to evolved, “domain-specific psychological modules” (such as a dedicated mechanism that automatically generates a feeling of concern when confronted with suffering) in shaping the content of our moral feeling, judgment and behavior, both through shaping our cultures and more directly; other accounts, while not denying some such influence, will emphasize very different factors as influencing the content of at least some of our moral beliefs (such as the “capacity for open-ended normativity” cited by Buchanan and Powell 2015, 2018, 2019). This brings us to the next major topic.
