[QUOTE]Originally posted by lamin: [QB] Djehuti,Lioness, et al. The issue of "race" is complex. Nature does not delineate according to "race". Humans impose their own taxonomic criteria on human populations to come up with their racial classifications. European anthropologists have been the majority on this issue. Some of them have said there are 3 races while others have argued for over 30. European anthropologists Ripley and Coon have each written a book titled "The Races of Europe"--Alpine, Nordic, and Mediterranean. Some even argued for "Semitic" and "Hamitic" races. Even today some continue to argue for the simple-minded "Caucasoid", "Mongoloid", and "Negroid" races. Not very intelligent here. Point is that you have human populations that have behaved like clouds over millennia: they split apart thereby creating "genetic drift" and quite often they encounter each other again. So let us look at human populations as "breeding populations" that when split apart acquire genotypical and phenotypical traits based on concepts such environmental selection, assorted mating, etc. The result is that you eventually get human population "isolates" that even so share certain phenotypical traits derived from similar environmental conditions--e.g. isolate populations that have long experienced tropical conditions often evolve heavily pigmented epidermises. As with tropical zone Africans and South Asians. Think of human populations as intersecting sets[basic mathematical set theory] that share many genomic criteria but not all. Isolate populations may share skin colour but differ in hair form. Analyses using Haplogroup analysis and MRCA help but not totally when populations are subject to genetic drift and environmental pressures. The best analysis should be a loose one: in the case of Africa you will have East, West, North and Southern African populations. For Asia: North East Asian, South East Asia, South Asia, North Asia, etc. So simple chromatic tests about "race" in terms of colour are simply unworkable. Hair form and eye forms may work most of the time but there are many exceptions. That's Nature for you: always moving, adapting, evolving, sneaking in new traits, eliminating old ones, etc. [/QB][/QUOTE]
