The rapid change in many aspects of morality, even in the last century, also suggests that much of its "innateness” comes not from evolution but from learning. That's because evolutionary change simply doesn't occur fast enough to explain societal changes like our realization that women are not an inferior moiety of humanity, or that we shouldn't torture prisoners. The explanation for these changes must reside in reason and learning: our realization that there is no rational basis for giving ourselves moral privilege over those who belong to other groups.
