[QUOTE]Originally posted by zarahan: [QB] [QUOTE]Originally posted by Morpheus: [qb] What?! That quote definitely does NOT support your racial categories. That quote comes from Tishkoff (2000) which doesn't say anything about modern humans structuring into races. It pretty much reiterates what the American Anthropological Association says about non-African populations being a sub-set of African populations: [URL=http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1287905]Short Tandem-Repeat Polymorphism/Alu Haplotype Variation at the PLAT Locus: Implications for Modern Human Origins[/URL] From the same study: [i]These studies suggest a recent and primary subdivision between African and non-African populations, high levels of divergence among African populations, and a recent shared common ancestry of non-African populations, from a population originating in Africa. The intermediate position, between African and non-African populations, that the Ethiopian Jews and Somalis occupy in the PCA plot also has been observed in other genetic studies (Ritte et al. 1993; Passarino et al. 1998) and could be due either to shared common ancestry or to recent gene flow. [b]The fact that the Ethiopians and Somalis have a subset of the sub-Saharan African haplotype diversity and that the non-African populations have a subset of the diversity present in Ethiopians and Somalis makes simple-admixture models less likely[/b]; rather, these observations support the hypothesis proposed by other nuclear-genetic studies (Tishkoff et al. 1996a, 1998a, 1998b; Kidd et al. 1998)that populations in northeastern Africa may have diverged from those in the rest of sub-Saharan Africa early in the history of modern African populations and that a subset of this northeastern-African population migrated out of Africa and populated the rest of the globe. These conclusions are supported by recent mtDNA analysis (Quintana-Murci et al. 1999). [/i] How about posting a study that actually provides a scientific basis for these racial categories that you've listed or any racial categories for that matter? [/qb][/QUOTE]Indeed... [/QB][/QUOTE]
