The origins of moral judgment

Is human morality a biological adaptation? And, if so, should this fact have any substantial impact on the ethical inquiry of how we should live our lives? In this paper I will address both these questions, though will not attempt definitively to answer either. Regarding the former, my goal is to clarify the question and identify some serious challenges that arise for any attempt to settle the matter one way or the other. Regarding the latter, my ambitions here are restricted to some brief critical comments on one recent attempt to answer the question in the affirmative.
