The Missing Link of Jewish European Ancestry: Contrasting the Rhineland and the Khazarian Hypotheses
The question of Jewish ancestry has been the subject of controversy for over two centuries and has yet to be resolved. The "Rhineland hypothesis" depicts Eastern European Jews as a "population isolate" that emerged from a small group of German Jews who migrated eastward and expanded rapidly. Alternatively, the "Khazarian hypothesis" suggests that Eastern European Jews descended from the Khazars...
More than a third of the European pool of human mitochondrial DNA (mtDNA) is fragmented into a number of subclades of haplogroup (hg) H, the most frequent hg throughout western Eurasia. Although there has been considerable recent progress in studying mitochondrial genome variation in Europe at the complete sequence resolution, little data of comparable resolution is so far available for regions...
African swine fever (ASF) is now established beyond Africa, in the Caucasus and the Russian Federation, where it is having a particularly devastating impact on small-scale pig farmers, who are losing a valuable protein source and cash income. In the past, the virus was already detected outside Africa from the 1950s to the 1980s in Europe, the Caribbean and Brazil. The recent developments in Eas...
Currently, 17 species of aquatic dance flies of the genus Wiedemannia are known from the Caucasus including four new species: W. ivkovicae sp. nov. (South Ossetia), W. nartshukae sp. nov. (South Ossetia), W. ossetiana sp. nov. (South Ossetia) and W. pseguashae sp. nov. (Georgia, South Ossetia). Wiedemannia (Chamaedipsia) lota Walker 1851 (Russia; Georgia) is recorded from the Caucasus for the f...
with the collapse of the soviet :union:, vacuum of power emerged in the south caucasus. this matter has sparked trans-regional and regional powers competition. the newly established republics create challenges and opportunities for iran and turkey. the result of this situation is the competition between tehran and ankara in the region. this topic is highly important in regional equations becaus...
view. in this paper, the question of influence in the south caucasus and europe :union: foreign policy . a. iran 's regional interests can be defined both in terms of cooperation or conflict , has developed the hypothesis that the objectives and activities of the :union: of europe in the caucasus show that not only the conflict of the conflict between the interests of and the there is no :...
We analyzed 40 single nucleotide polymorphism and 19 short tandem repeat Y-chromosomal markers in a large sample of 1,525 indigenous individuals from 14 populations in the Caucasus and 254 additional individuals representing potential source populations. We also employed a lexicostatistical approach to reconstruct the history of the languages of the North Caucasian family spoken by the Caucasus...
the expansion of grey- black pottery tradition in the iranian plateau, on the basis of iron age theory of cultural dynamism, was emerged by the end of the 2nd millennium bc. such a pottery tradition is regarded as a cultural sign to point migrants who entered in the iranian plateau from the northern outside of caucasus the major. according to the theory, the migrants passed the river valley of ...
The topology of the network of western Eurasian mitochondrial DNA (mtDNA) lineage clusters in the context of their expansion and spread in this geographic area is analysed. Special attention is devoted to the inner nods of the reconstructed median network tree, ancestral to mtDNA lineage clusters H and V, to the Caucasus and TransCaucasus area populations and to the problem of timing of the exp...
We have analyzed mtDNA HVI sequences and Y chromosome haplogroups based on 11 binary markers in 371 individuals, from 11 populations in the Caucasus and the neighbouring countries of Turkey and Iran. Y chromosome haplogroup diversity in the Caucasus was almost as high as in Central Asia and the Near East, and significantly higher than in Europe. More than 27% of the variance in Y-haplogroups ca...
