 It is uncontroversial that there will be evolutionary explanations of some sort for the very general capacities and tendencies in A and B: we are evolved creatures, and our psychological capacities, like other complex capacities, are outcomes of evolutionary processes. But this does not by itself settle whether these capacities and tendencies are themselves adaptations, having evolved through natural selection because of their adaptive effects. That is the most common view (further explored below), but there are alternatives.
