[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Troll Patrol # Ish Gebor: [qb] Arab ethic groups are diverse. And like too so in genetics. J1 likely arose at the Sinai aka South Levant, and diverted from there in-and-out of Africa. [IMG]http://www.arcane.uni-tuebingen.de/rg1/sl1.gif[/IMG] [/qb][/QUOTE]Indeed. Populations of a region can change quite drastically over time. Note that according to the last major study by Ehret et al. using bayesian analysis Proto-Semitic originated approximately 4,000 BCE during the chalcolithic period or rather the very end of the neolithic and very beginning of the bronze age. [IMG]http://oi56.tinypic.com/29270jo.jpg[/IMG] Recall the results of a study was done on the DNA of human remains in Jordan in the Dead Sea area dating to the Bronze Age: [i]Abstract A high-resolution, Y-chromosome analysis using 46 binary markers has been carried out in two Jordan populations, one from the metropolitan area of Amman [b]and the other from the Dead Sea,[/b] an area geographically isolated. Comparisons with neighboring populations showed that whereas the sample from Amman did not significantly differ from their Levantine neighbors, [b]the Dead Sea sample clearly behaved as a genetic outlier in the region. Its high R1*-M173 frequency (40%) has until now only been found in northern Cameroonian samples.[/b] This contrasts with the comparatively low presence of J representatives (9%), which is the modal clade in Middle Eastern populations, including Amman. [b]The Dead Sea sample also showed a high presence of E3b3a-M34 lineages (31%),[/b] which is only comparable to that found in Ethiopians. [b]Although ancient and recent ties with sub-Saharan and eastern Africans cannot be discarded,[/b] it seems that isolation, strong drift, and/or founder effects are responsible for the anomalous Y-chromosome pool of this population. These results demonstrate that, at a fine scale, the smooth, continental clines detected for several Y-chromosome markers are often disrupted by genetically divergent populations.[/i] --Carlos Flores et al 2005 And here is a reconstruction of the skulls of a Bronze Age couple from modern Bab Edh-Dhra again near the Dead Sea (near ancient Sodom of Sodom and Gommorah infamy): [IMG]http://farm3.staticflickr.com/2245/1573736838_91f86af438.jpg[/IMG] [IMG]http://www.bibleandscience.com/tours/images/bab3.jpg[/IMG] ^ Despite the fanciful skin and hair color, note the Natufian features of prognathism and prominent zygomatic bones. The implications are as clear as they are dramatic. By the way, I am of the same opinion as our friend Yom (moderator Henu) that Proto-Semitic itself was a member of a larger Afrasian sub-family (Pre-Proto-Semitic) which it soon subsumed as its descendants spread and took over the region.
