why would you assume this? it could very well be out there. the problem spuriousmonkey has with you could be that you refuse to learn from us, you refuse to teach yourself by doing the literature research, and you rely on unsubstantiated personal opinion when we could probably help you understand it if you would only ask. the problem with this is that it's subjective. it is not logically or scientifically valid to say, "all these people look alike based on these characteristics, therefore they are a race (or group or whatever). it is, however a valid question becasue it can be tested genetically, and can be refuted. i will not argue anthropologic data as it's not my field, but certainly there is cultural heredity with NO biological heredity. isn't that why we have schools? as i said before, people have problems separating biology from sociology when discussing human 'race.' What???!!!?? that's exactly one of the reasons why you said it was important??? this is what we are telling you! this has been tried and tested with a number of different 'racial' traits and it has been refuted. it is valid! your way of picking genes subjectively is invalid. genes are inherited not singly, but as a group, i.e. the haploid genome. all the genes have to be considered. this is impossible realistically so one takes an unbiased sample of the genes and compares them.
