[QUOTE]Originally posted by Doug M: [QB] [QUOTE]Originally posted by Swenet: [qb] Including new Sahelian samples with known affinities you get, well.. known affinities. [IMG]http://gbe.oxfordjournals.org/content/7/12/3484/F1.large.jpg[/IMG] [/qb][/QUOTE]The point is there should be a gradient of overlapping gene pools from the Sahara into West Africa and not some abrupt split from "North Africans" to "Sub Saharan" Africans. Populations along and within the Sahel should be intermediate to Eurasians and West Africans, assuming mixture during historic periods. Yet even with that they should also retain older ancestral indigenous African ancestry. My issue is that their sample sets are designed to promote a narrative of North African populations being "isolates" and separate genetically from the rest of Africa. By not sampling those populations spread thinly across the Sahara and Sahel they are purposely selecting data that reinforces that notion. Case in point, if you sample all the populations in Libya from the coasts all the way down to the Southern regions, you will see a lot more genetic diversity than what is implied by the current sample sets, which tries to fit all Libyans into one population cluster genetically. The problem is all the populations in Libya DON'T fit into the same population cluster. The populations nearer to the coast have more Eurasian ancestry as would be expected and the ones in the South have more African ancestry as again would be expected, due to less Eurasian mixture. That pattern applies across all of the countries bordering the Mediterranean including Egypt. Obviously slavery has nothing to do with the presence of these Africans in the southern areas, but that is exactly what they keep trying to imply and suggest..... which is the dumbest and most racist nonsense that they keep spewing in these studies.
