[QUOTE]Originally posted by Calypso: [QB] Dr. Winters wrote: [QUOTE]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.[/QUOTE]Dr. Winters think about it: They used some criterion to separate people into groups to begin with. They concluded that there are differences in the rate with which these people copy some genes. No one has ever said that there are no observable differences among people from different regions. Why do you consider differential rates of production of the genes in question as greater proof of the existence of race than the primary set of criteria used to separate the individuals in the first place? [QUOTE]They have found that each of us is more different genetically than we previously believed. Instead of being 99.9 per cent identical, it may turn out to be more like 99 per cent identical - enough of a difference to explain many variations in human traits. Instead of having just two copies of every gene - one from each parent - we have some genes that are multiplied several times. [b]Furthermore these "multiple copy numbers" differ from one person to another, which could explain human physical and even mental variation.[/b][/QUOTE]You highlighted the last paragraph above but it seems to me they're talking about individual differences here not racial differences. How does this help you? [/QB][/QUOTE]
