ORIGINAL: RealityLicks Actually, Alumbrado was closer to the truth when he said that the jury was still out. At present, what can be done with a fair measure of accuracy is to identify an individual by population. Effectively this is often the same as being able to distinguish their race - if someone has a marker for people in say, North Western Guinea-Bissau, it's likely they are black. But improving the system for spotting these markers is not the same as being able to identify genetic traits. That is either light years away ... or impossible. So it is still the case that, given a DNA sample blind, any attempt to discern the donor's race is a guess. More accurate than it once was but still a guess. Scotland Yard or the FBI do use this to place a suspect's race (which is why criminals steal your fag butts - to leave them at their crime scenes!) but it's not the same as there being genetic evidence of race. As yet, there isn't any. "Misconceptions persist because of the belief that biological races exist in anatomically modern humans. Here are some of the common examples. Races differ in intellectual ability, morality and temperament. Races differ in athletic abilities. Races differ in sexual appetites, in particular that blacks are hypersexual. Races have specific diseases, thus membership in race with predict an individual's disease predisposition. Again, this is inconsistent with what we know about the genetic variation in humans, so if we apportion human genetic diversity there are 86% shared in all world populations. Every population in the world has these genes, but may have them at different frequency. Of these, 10% are unique to a given continent, and 4% are unique to a specific local population. People have said to me, 'Professor Graves, that means that if you have 4% that are unique to a specific population, couldn't you use those 4% to identify a race?' I said, yes, if you want to do it that way; you could. But that would mean that we've got about 2000 races in the human species because you can identify these 4% of rare alleles to specific geographical regions. What's the point in identifying any of them if you have so many? You would have races by every hilltop, every valley, every divide in a river. At that level, the whole idea breaks down." http://www.ahc.umn.edu/bioethics/afrgen/html/Themythofrace.html There's much more materiel in that link, but that more or less sums up why I do not accept that there "races" in the Human Genome. Here's an interesting article from that pseudo-lib hate-mongering rag Nature: http://www.nature.com/ng/journal/v36/n11s/full/ng1435.html This is fascinating, too. I haven't finished reading it, however. http://www.nchpeg.org/raceandgenetics/index.asp "Today most scientists study human genotypic and phenotypic variation using concepts such as "population" and "clinal gradation". Many contend that while racial categorizations may be marked by phenotypic or genotypic traits, the idea of race itself, and actual divisions of persons into races, are social constructs." http://en.wikipedia.org/wiki/Race_%28classification_of_human_beings%29
