Catholigauze blogged the last genetic map of Europe and numerous friends asked me for my thoughts on it, so I thought I would be ahead of the curve and post the latest version of how they can place your ancestry by your DNA (hat-tip to gnxp):
Baby boomers — and those taught by them — have long since digested the conventional wisdom that there are no “races,” that ancestral populations exist only in social construction, and that we all come with the same abilities when we are born (or at least, that different “races” all come with the same average abilities and same variation in thsoe abilities, statistically). Of course, this is not true. Not only are we able to identify this race from that, this population from that, we are zooming in farther and farther in the data: what valley did your ancestors come from? We may soon be able to tell you.
Exposing the fallacy of equal-ability–when-treated-equally-at-birth is a grave challenge, both to those Marxists who insist on a “blank slate” and to those conservatives who insist on laissez faire policies because everyone can just pull themselves up by their bootstraps. But this political debate, finally, is being impacted by the latest in scientific knowledge.
