Further thoughts on the evolution of pride's two facets: A response to Clark

In Clark's thoughtful analysis of the evolution of the two facets of pride, he suggests that the concurrent existence of hubristic and authentic pride in humans represents a "persistence problem," wherein the vestigial trait (hubristic pride) continues to exist alongside the derived trait (authentic pride). In our view, evidence for the two facets does not pose a persistence problem; rather, hubristic and authentic pride both likely evolved as higher-order cognitive emotions that solve uniquely human-but distinct- evolutionary problems. Instead of being conceptualized as serial homologues, with one the vestigial form of the other, we argue that hubristic and authentic pride are both derived homologues of a vestigial proto-pride emotion that existed in our shared ancestry with other primates.
