Our mating decisions make us unwitting futurists
Our mating choices show incredible foresight. For example, mating outside one's race at one point was verboten, but those who dared do so had children who are now ready for a multi-cultural world, one that relishes the spectrum. Or mating with a nerd may have brought derision at one point, but whoever did so prepared their children for the world of today, where the creative class is supreme. Even though it seems like we mate according to whim, beneath that is a fiercely competitive genetic logic. Our genes take risks to ensure that in the race for better progeny, you won't just have the best shot today, but the best shot in a tomorrow created by everybody already taking their best shot.
