Scientists studying the DNA of 52 human groups from around the world have concluded that people belong to five principal groups corresponding to the major geographical regions of the world: Africa, Europe, Asia, Melanesia and the Americas. The study, based on scans of the whole human genome, is the most thorough to look for patterns corresponding to major geographical regions. These regions broadly correspond with popular notions of race, the researchers said in interviews. The researchers did not analyze genes but rather short segments of DNA known as markers, similar to those used in DNA fingerprinting tests, that have no apparent function in the body... The issue of race and ethnicity has forced itself to biomedical researchers' attention because human populations have different patterns of disease, and advances in decoding DNA have made it possible to try and correlate disease with genetics. The study, published today in Science, finds that "self-reported population ancestry likely provides a suitable proxy for genetic ancestry." In other words, someone saying he is of European ancestry will have genetic similarities to other Europeans... a leading population geneticist, Dr. Neil Risch of Stanford University, argued recently that race was a valid area of medical research because it reflects the genetic differences that arose on each continent after the ancestral human population dispersed from its African homeland... The new result is based on blood samples gathered from around the world as part of the Human Genome Diversity Project, though on a much less ambitious scale than originally intended. Dr. Feldman and his colleagues analyzed the DNA of more than 1,000 people at some 400 markers. Because the sites have no particular function, they are free to change or mutate without harming the individual, and can become quite different over the generations.

The Neandertal EnigmaFrayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

:’) Thanks knarf.
Interesting, but the article didn’t seem to give a definition for Asian. Do the genetics match the geographic dividing line (the Ural Mountains, Caucasus Mountains, Turkish straits and Sinai) or does the European bloodline include the Mid East and India with the Asian one in Eastern Asia? Similarly, did the African grouping include just south of the Sahara or did they try to group those north into it?
The study still does not explain Helen Thomas.
I would take that grouping to include the Australian aborigines.
Fine, you can go study her.
Thank you knarf!
OK How about just three, Ham, Shem and Japheth Noah’s sons.
But it does refer to "popular notions of race," which would seem to indicate that "Asian" corresponds to dark hair and the presence of the epicanthic fold about the eyes.
None of this is particularly surprising, of course, though I suppose it does sorta pop the bubble of those who suggest that there is no genetic basis for the idea of race.
That position is, of course, primarily an ideological one.

LOL, my favorite line!!
You CAN’T hide from blam!! Nice job...
This is why I didn’t answer the race question on my census.
I haven’t had a DNA test done yet - not going to lie/s
The problem with climbing *his* family tree is, not falling off that twisting ladder. ;’) The surname family group is still running a genome project, I’m saving up my pennies to get the broadest one available.
I’m holding *you* responsible when her picture is posted in here. ;’)
It’s probably in the original paper, which I hope someone will excerpt, post, or make available (PDF, .doc, HTML, whatever) for download.
Well, I actually searched for that exact title, now I’m feelin’ bad...
I anticipated that problem, but I got a dyslexic doctor, and he performed the AND test instead. Total waste of five bucks.
