[QUOTE]Originally posted by xyyman: [QB] What "foreign" incursion. Africans invading Africa is not....foreign. Many fail to realize the Bedouins of the Levant and Arabia are the indigenous population of the Levant and Arabia. The Bedouins are Africans from the Nile and North Africa. Sources cited. [IMG]http://i45.tinypic.com/30a9n6a.jpg[/IMG] RESULTS: Statistical analysis revealed that, whereas the sample from Amman did not significantly differ from their Levantine neighbours, [b] the Dead Sea sample clearly behaved as a genetic outlier in the region.[/b] Its outstanding Eurasian haplogroup U3 frequency (39%) and [b]its south-Saharan Africa lineages (19%) are the highest in the Middle East[/b]. On the contrary, the lack ((preHV)1) or comparatively low frequency (J and T) of Neolithic lineages is also striking. Although strong drift by geographic isolation could explain the anomalous mtDNA pool of the Dead Sea sample, the fact that its mtDNA lineage composition mirrors, in geographic origin and haplogroup frequencies, its Y-chromosome pool, [b]points to founder effect as the main cause[/b]. Ancestral M1 lineages detected in Jordan that have affinities with those recently found in Northwest but[b] not East Africa [/b]question the African origin of the M1 haplogroup. CONCLUSION: Results are in agreement with an old human settlement in the Jordan region. However, in spite of the attested migratory spreads, genetically divergent populations, such as that of the Dead Sea, still exist in the area [/QB][/QUOTE]
