[QUOTE]Originally posted by Supercar: [QB] I notice some correlations being made between 'autosomal' marker findings and Y chromosome markers. I can understand that this is being rationaled to the extent of invoking the last shared common ancestry between said groups; however what I cannot understand, is to assume that autosomal markers would be effective in clearly discerning this as does the Y chromosomes, and somehow show that geographically closer populations with historic documentations of intermingling can be relatively more genetically distant [via autosomal analysis] than any two given populations who have considerably been separated from one another in both a spatial and temporal sense. [QUOTE]Originally posted by rasol: [QUOTE]mayne that atuosomal dendogram is full of contradictions, Somalis have little to no E3b*[/QUOTE]According to: [b]Phylogeographic Analysis of Haplogroup E3b (E-M215) Y Chromosomes Reveals Multiple Migratory Events Within and Out Of Africa[/b] Somali have E3B* at 17 %, whereas San have E3b* at between 12% and 35%. [URL=http://www.journals.uchicago.edu/AJHG/journal/issues/v74n5/40866/40866.html]read here[/URL] ^ note: i'm not trying to use Cruciani's new private nomenclatures because I don't understand it yet. So, if you are going to relate based on this, you will need to explain to me the exact relationship between Somilian and SouthEast African E3b, and how it cannot be linked to the autosomal affinities between Somalians and South/South East Africans. [/QUOTE]I think the question should rather be: how does the TMRCA, as attested to by E3b, can be linked to genetic distance found between populations, especially when they have been separated for a considerable time, naturally in addition to geographical & corresponding cultural separation?
