Why should they ignore this? People are geographically related. There's a news flash. How do these slight genetic differences constitute justification for the classification of races? Last time I knew the genetic variation between people in the same population was greater than the difference between people in different populations. Has that changed?
How do these slight genetic differences constitute justification for the classification of races? They don't. And the PC New York Times left out that part, preferring to spin their PC race difference ideology (shared here by many fake conservative parasite Freeping types).
This study said that appearance can not indicate what geographic/race traits one may have. In other words, a "black" is just as likely to have european markers and vice versa all around.
