C.I.T.O.K.A.T.E.

Actually, that is the key question, and what I neglected to ask in my most recent LJ, but should have. I know that the prefrontal cortex is very much involved in the ability to follow social norms. Social norms really are, effectively, the same thing as morality. Or rather, morality is the product of social norms. If our prefrontal cortex did not have the particular type of organization it has, whatever that may be, we may not ever have evolved a complex system of morals. But just how specifically can genetics control such a thing? That's really hard to tell. There is an argument for a non-genetic component, based purely on sociology, and the "passing down" of morality from one generation to the next, primarily via story telling. But then again, our ability to tell stories is also genetically encoded as a particular brain structure/organization, so I guess I'd have to say whatever the answer, it is complex and multifactorial, but ultimately not inexplicable.
