Blue Eyes "Invented" less than 10kya?

Steve Sailer has a good piece from the LATimes that quotes one of my fave anthros at UofWisc, John Hawks.

As blue eyes are recessive, it takes two parents with baby blues to produce a baby with blues. Or at least, blue-eyed parents can't produce a brown-eyed girl---unless the milkman came early.

As an afterthought, Hawks mentions that the larger the population, the faster evolution proceeds in humans---so it's going to be a bumpy ride in the pop-boom USA.
