[QUOTE]Originally posted by Clyde Winters: [QB] X-Ras [QUOTE] LOL, come on now Clyde, since you could not prove that the said 13 authors proved race exists you're going to use this to prove your argument? Black refers to skin color, not race. [/QUOTE]Ha,Ha. Thanks for the joke. How can you tell the skin color of a skeleton on color of a person from his genes unless you are using the term Black or white to refer to a race. As a result, when people use the term Black African to refer to Egyptians they are using the term "Black" to designate a racial group just like the authors of the study under discussion. . What are you talking about I confirmed that the authors determined races biologically: [QUOTE][b] http://tinyurl. com/yh7kp2 There are just under 30,000 genes in the human genome, which consists of about 3 billion "letters" of the DNA code. The scientists found that more than 10 per cent of these genes appear to be multiplied in the 270 people who took part in the study. They do not know why some genes are copied and some are not. One gene, called CCL3L1, which is copied many times in people of African descent, appears to confer resistance to HIV. Another gene involved in making a blood protein is copied many times in people from south-east Asia and seems to help against malaria. Other research has shown that variation in the number of copies of some genes is involved in Alzheimer's and Parkinson's disease. Are there any other practical applications? The scientists looked at people from three broad racial groups - African, Asian and European. Although there was an underlying similarity in terms of how common it was for genes to be copied, there were enough racial differences to assign every person bar one to their correct ethnic origin. This might help forensic scientists wishing to know more about the race of a suspect. Who made the discovery and where can we read more about it? Scientists from 13 research centres were involved, including Britain's Sanger Institute in Cambridge, which also took a lead role in deciphering the human genome. The research is published in Nature, Nature Genetics and Genome Research. [/QUOTE][/b] [/QB][/QUOTE]
