I don't agree Ryan. Speciation is overblown, as it takes isolated populations and I don't think the selectors are strong enough or persistent enough. Yesterday's loser-nerds are today's cryto-millionares are tomorrow's loser-nerds. I've witnessed an earl, the scion of a wealthy, Engish, noble family, lecturing American millionaires about how he was genetically predisposed to rule. "Breeding" he said, as he rented out rooms and entertained paying guests in his hereditary estate in order to earn the money keep it from collapsing into a shambling ruin. And what was this genetic predisposition based on? The ability of his Germanic barbarian ancestors to defeat other Germanic barbarians in physical combat. If some form of speciation were to occur, I think we would have seen signs of it by now, since aristocrats didn't marry peasants and vice versa. Yet all we've seen is hemophilia and other signs of inbreeding. The results of several centuries of crypto-nerd inbreeding would be truly frightening.
