[QUOTE]Originally posted by KingMichael777: [QB] [QUOTE]Originally posted by Djehuti: [qb] [QUOTE]Originally posted by the lioness: [qb] some suggest that Africans are related by Haplogroup E1b1 (P2, DYS391p); formerly E3 [/qb][/QUOTE]The PN2 or E clade is just one of many present in Africa, though E appears to be predominant. Within E you have E1, E2, E3 etc and within each subclade there are more divisions and variations. Again E though a significant clade is just one aspect shared by Africans. Another problem in African population studies is the designation of certain clades as non-African or Eurasian. For example the R clade and in particular R1 is classed as Eurasian since that is where its subclades are predominantly found. R1a and R1b for example are carried by eastern and Western Europeans respectively with the former also found in Central Asia etc. Yet there are also subclades of R1 and even underived R1* present in Africa, specifically in [i]West[/i] Africa. Yet these lineages are found in rural areas devoid of any European or Eurasian contact. There are some scientists who try to explain this by prehistoric back-migrations from Eurasia yet the problem is the very dating of R1* goes back to the time when humans first left Africa to populate Eurasia. So why can't R1 be defined as African instead of Eurasian?? What's funny is that Eurocentric racialists try to associate any so-called 'Eurasian' lineage in Africa with stereotyped "caucasian" features yet all the carriers of R1 derived haplogroups in West Africa are stereotypically "negroid" in characteristics yet nobody tries to 'relate' these so-called "forest negroes" with indigenous white Europeans who carry share the same clade! [b]LOL[/b] In the meantime there are Europeans especially southern Europeans in the Mediterranean who carry E lineages clearly inherited from Africans in the neolithic, yet you hardly hear a peep about African migrations into Europe and African admixture among Europeans when that is clearly the case! [QUOTE]Originally posted by KingMichael777: [qb] I see. Also I'm just curious but DNAtribes said...the Massai are 30% Arab and Somalis 40% Arab, 30% West African, 30% Sahelian. I'm just curious. [/qb][/QUOTE]This is also why I question DNATribes when it comes to how they label or classify things. Exactly what do they mean by 'Arab'?? What haplogroup or other do they refer when they say 'Arab'. Last time I checked the Massai have had no historical contact with Arabs whatsoever yet they are suppose to be 30% 'Arab'?? And what percentage of Europeans like Greeks are African, since again about a third of Europeans in general carry E lineages with about a quarter of Greeks carrying E. Again there is this biased slant to white-wash or rather 'mix-up' Africans but nothing is said about mixed ancestry in Europeans. [/qb][/QUOTE]So are they really accurate or not accurate?
