[QUOTE]Originally posted by zarahan- aka Enrique Cardova: [QB] [IMG]http://3.bp.blogspot.com/-uGt_SDejsmU/VRio94wtU1I/AAAAAAAABZ4/XtqIAyIc9Js/s1600/floresisolates2_deadsea.jpg[/IMG] [i]As Bedouin tribes had an important role in the colonization of southeast Jordan, it could be that the haplogroup composition of the Dead Sea reflected genetic affinities to them, but that is not the case. The most striking characteristic of the Dead Sea sample is the high prevalence of R1*-M173 lineages (40%), contrasting with the lack of them and of its derivatives R1b3-N269 in Bedouin from Nebel et al. (2001) and its low frequencies in Amman. It is worth mentioning that until now, similar frequencies for R1*-M173 have only been found in northern Cameroon (Cruciani et al. 2002). The possibility that the Dead Sea and Cameroon are isolated remnants of a past broad human expansion deserves future studies. Interestingly, when the molecular heterogeneity of the G6PD locus was compared between the Amman and the Dead Sea samples, a lower number of different variants and a higher incidence of the African G6PD-A allele was detected in the latter (Karadsheh, personal communication). Another singularity of the Dead Sea is its high frequency (31%) of E3b3a-M34, a derivative of the E3b3-M123 that is only found in 7% Bedouins (Cruciani et al. 2004). Until now, the highest frequencies for this marker (23.5%) had been found in Ethiopians from Amhara (Cruciani et al. 2004). On the contrary, most Bedouin chromosomes (63%) belong to the haplogroup J1-M267 (Semino et al. 2004) compared with 9% in the Dead Sea. All these evidences point to the Dead Sea as an isolated region perhaps with past ties to sub-Saharan and eastern Africa. "the first component clearly separates the Middle East eastern regions (Pakistan, Iran and Kurds) from the African samples and Oman.. the negative displacement is mainly driven by African haplogroups. The second component again displaces Oman, Somalia, and Egypt, mainly due to their relative abundance of lineages with sub-Saharan African adscription.." [/i] --Flores, et al. 2005.
