The New York Times has a cool series of articles listed under a main title called The DNA Ages. I haven’t had the change to read all of them but the ones I’ve caught now and then have been pretty good.
The latest installment is related to an aspect of DNA testing that I hadn’t thought about since I guess, this topic doesn’t come into mind often; The topic is racism and prejudice.
Various studies have demonstrated (or tried) the small differences between people of different races, which can come down to a difference in a couple of nucleotides.
However, although I did enjoy the article, I couldn’t happen to feel that it brought about a pessimistic image of DNA testing and how it focused more on faults than features – as if genetic knowledge left the glass half empty, and not the other way around.
