Contemporary Jews comprise an aggregate of ethno-religious communities whose worldwide members identify with each other through various shared religious, historical and cultural traditions1, 2. Historical evidence suggests common origins in the Middle East, followed by migrations leading to the establishment of communities of Jews in Europe, Africa and Asia, in what is termed the Jewish Diaspora3, 4, 5. This complex demographic history imposes special challenges in attempting to address the genetic structure of the Jewish people6. Although many genetic studies have shed light on Jewish origins and on diseases prevalent among Jewish communities, including studies focusing on uniparentally and biparentally inherited markers7, 8, 9, 10, 11, 12, 13, 14, 15, 16, genome-wide patterns of variation across the vast geographic span of Jewish Diaspora communities and their respective neighbours have yet to be addressed. Here we use high-density bead arrays to genotype individuals from 14 Jewish Diaspora communities and compare these patterns of genome-wide diversity with those from 69 Old World non-Jewish populations, of which 25 have not previously been reported. These samples were carefully chosen to provide comprehensive comparisons between Jewish and non-Jewish populations in the Diaspora, as well as with non-Jewish populations from the Middle East and north Africa. Principal component and structure-like analyses identify previously unrecognized genetic substructure within the Middle East. Most Jewish samples form a remarkably tight subcluster that overlies Druze and Cypriot samples but not samples from other Levantine populations or paired Diaspora host populations. In contrast, Ethiopian Jews (Beta Israel) and Indian Jews (Bene Israel and Cochini) cluster with neighbouring autochthonous populations in Ethiopia and western India, respectively, despite a clear paternal link between the Bene Israel and the Levant. These results cast light on the variegated genetic architecture of the Middle East, and trace the origins of most Jewish Diaspora communities to the Levant.

Figure 1: PCA of high-density array data. a, Scatter plot of Old World individuals, showing the first two principal components. Each ring corresponds to one individual and the colour indicates the region of origin (for the full figure see Supplementary Fig. 2). b–d, A series of magnifications showing samples from Europe and the Middle East (b), Ethiopia (c) and south Asia (d). Each letter code (Supplementary Table 1) corresponds to one individual, and the colour indicates the geographic region of origin. In b, a polygon surrounding all of the individual samples belonging to a group designation highlights several population groups.

Figure 2: PCA of west Eurasian high-density array data. Plot of kernel densities (Supplementary Note 2) for each population sample (n > 10) was estimated on the basis of PC1 and PC2 coordinates in Supplementary Fig. 3. Individuals from these samples were plotted by using PC1 and PC2 coordinates and were overlaid with the plot of kernel density.

Figure 3: Population structure inferred by ADMIXTURE analysis. Each individual is represented by a vertical (100%) stacked column of genetic components proportions shown in colour for K = 8. The Jewish communities are labelled in colour and bold. T and B further specify Sephardi Jews from Turkey and Bulgaria, respectively. Populations introduced for the first time in this study and analysed together with the Human Genome Diversity Panel18 data are marked with an asterisk.

Jews Yemenite samples are located closer to Saudi and Bedouins populations i.e. same geographical area. Similarly, Ashkenazi and Georgian Jew cluster closer to the Georgian and Armenian population, i. e. same geographical area. Even the Moroccan Jews cluster outside of the Levant populations. From PCA it is clear that Jews outside Levant cluster closer to their native population rather than to the Jews or non Jews from Levant.

In my hypothesis, the "L2" mtDNA marker is present in the two populations also the derived and sibling mtDNA Hg "M" and "N", as well as the Y markers Hg E3b and 4s too, all of this from East Africa and so. They belong respectively at one of the three nucleous or center jewish ancient populations, that evolving the called "Syrian-European nucleous"(helenistic and Roman times).
The oldest center
Ethiopians belong thesewere that developed in Napata and Elephantine (Kush) and whose nucleous or center was after Alexandria, and I called "Coptic Nucleous" derived in two bias, and split forwards the North via Europeintermixed with the Syrian Europe nucleousor the South, via Nile and the Horn Of Africa.The "Babilonian and Persian nucleous" is other of the above three mentioned centers and included Bukara, Iranian and Iraki mainly.
All of this Nucleous take Judaea and Israel like a axis and pendulo.
Another fourth Nucleous or center I call "East Europe"
not mainly conected with ME, is not ancient like the three others and was the Jewish Khazar Empire stiring into Askenazy current population and others. All of this events were naturaly intrajewish asimilations in all jews current populations.The Ashkenazim hyperhaploydia is explained by the superposition and overlay of diverse fount or source population , that are all of this of Jewish origin (that consider converted into intraJewish assimilations) , one coming from the ?Syrian European nucleous? ? that Sephardic as well as preAshenazim bring inside -. The other convergence were the ?Coptic Jewish nucleous?, coming from Alexandria, the main and largest Judaic center in ancient times ? the buried and graves in Jewish graveyards and catacombs of Tuscan, and Alsace as too Rhineland cities take a lot of Egyptian ornaments and display figures from these, as well as Y and mtDNA markers - . The great Jews migration from Egypt beginning after the Muslim invaders from Arabia in the VII AE century. The ?Babylonian and Persian nucleous? take place and contacts newly with and when the ?preAshenazim second fase? were migrating to the East Europe. A remarkable contact was with the fourth ?East Europe Jews nucleous?
not related or little related with ME, with the descendant of the Jews Khazarians ones, spreading every where and carrying a lot of East Europe and Eurasian markers. That happen between the XI and XII century AE.The Tuscan host populations come from Anatolia like infers mtDNA markers, and others, yet present today ? a thread Etruscan link – and are so common in South East Basin like Albanian, Grecian, Tunisian and Anatolian , as well as the entirely Italy and some South France spots, practical absent in central or North Europa or East Asia. If we compare Ashkenazy jews with this South European Tuscan population will see a more European genes pool coming from Europe than if we compare with Central and North European population.

See, my comment 11149 and 12952 in the above Html, with table 1
partial, remember that the sibling Hg "M" and "N"from "L3"too correspond to East African origin, and are not included at all-see complete table 1, in reference-.
