[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Son of Ra: [qb] Like I said most of these "Eurasians" mtDNA prior to the neolithic are no longer Eurasian and by the time of the Moors/Berbers they would have already mutated into African. Specifically U6. [/qb][/QUOTE]You have to understand that "Eurasian" and "African" are purely geographic terms and don't say much about the actual populations themselves let alone their relation to one another. Keep in mind that many of those clades called "Eurasian" are said to originate in Southwest Asia i.e. Arabia and Levant which are right next door to Africa. [IMG]http://openi.nlm.nih.gov/imgs/512/399/3227647/3227647_pone.0028239.g001.png[/IMG] Because the region is in such close proximity to Africa sharing the same geologic features and climate, the OOA populations who dwelt in this region were not much different from their brethren who stayed in Africa next door. And you yourself have admitted that the region to be an extension of Africa if you recall my thread [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=008310]here[/URL] Therefore whatever clades arose in these OOA people as "Eurasian" clades don't make much difference if they were reintroduced back into the continent. This is why Keita said: [i]The issue of how much Paleolithic migration from the Near East there may have been is intriguing, and the mitochondrial DNA variation may need to be reassessed as to what can be considered to be only of "Eurasian origin" [b]because if hunters and gatherers roamed between the Saharan and supra-Saharan regions and Eurasia it might be difficult to determine exactly "where" a mutation arose.[/b][/i] [IMG]http://64.40.115.138/file/lu/6/52235/NTIyMzV9K3szNDAwNTc=.jpg?download=1[/IMG] ^ The debate about which clades are 'Eurasian' or African is in regards to M and N and [i]some[/i] of their subclades. There is evidence to suggest M1 and N1 could have originated in Africa. But in regards to N subclades, and in particular R there seems to evidence of back-and-forth migration between Arabia ('Eurasia') and northeast Africa. [/QB][/QUOTE]
