Perhaps we can finally put to rest that old dichotomy: nature vs nurture. It never was an either/or question, and the only reason it was ever put forward as one is because humans are wedded to either/or, black-&-white propositions -- well, we'd all like a simpler world, but this is the one we've got (a many-shades-of-grey one). Anyway, forget the question: either nature or nurture; forget even the far more reasonable: how much nature and how much nurture. We are now in the realm of epigenetics -- which means, nature and nurture (particularly prenatal nurture) are indissolubly intertwined. And this has far-reaching consequences for any debates on intelligence.
