[QUOTE]Originally posted by Bettyboo: [QB] [QUOTE]Originally posted by MindoverMatter718: [qb] another study, different scientists, same results, too bad, sucks to be you..... [QUOTE] Distance from Africa, not climate, explains within-population phenotypic diversity in humans Lia Betti1, François Balloux2, William Amos1, Tsunehiko Hanihara3, Andrea Manica1 December 02, 2008 Abstract The relative importance of ancient demography and climate in determining worldwide patterns of human within-population phenotypic diversity is still open to debate. Several morphometric traits have been argued to be under selection by climatic factors, but it is unclear whether climate affects the global decline in morphological diversity with increasing geographical distance from sub-Saharan Africa. Using a large database of male and female skull measurements, we apply an explicit framework to quantify the relative role of climate and distance from Africa. We show that distance from sub-Saharan Africa is the sole determinant of human within-population phenotypic diversity, while climate plays no role. By selecting the most informative set of traits, it was possible to explain over half of the worldwide variation in phenotypic diversity. These results mirror those previously obtained for genetic markers and show that ‘bones and molecules’ are in perfect agreement for humans.

Please explain thoroughly how genetics is wrong, and can't trace ancestry? [/qb][/QUOTE]You are a real fvcking idiot. The 'article' you posted is not what we are discussing. They are discussing "phenotype". But what about those who are not distance from "sub-sahara" africa but possess different phenotype. This article is comical. Of course bone structure determines phenotype; this shyt don't need scientific studies, and it has nothing to do with what we are discussing. You're a fvcking idiot. Different studies, Different theorists, Different results. And phenotype don't come from being "distance" from Africa, and for them to say that climate don't have no role in phenotype is an automatic pink slip. [/QB][/QUOTE]
