More to come?
-->Hallo,
beinahe täglich - nicht immer Weltbewegendes z.B.:
(Hervorhebung von mir)
A newer study by Semino et al. [10] has studied two samples of Greeks of size 84 and 59 (Macedonian Greeks). The focus was on two specific haplogroups E and J which are frequent in the Mediterranean region and can be used to detect population movements between Europe, Africa and the Near East. 2.4% of Greeks belong in haplogroup E-M123 and 21.4% in E-M78. Clades of E prevalent in Northern or Sub-Saharan Africa were not found. According to Cruciani et al. [11] most Greeks and other Balkan people belong to a specific cluster α within haplogroup E-M78 that is found in lower frequencies outside the Balkans and marks migrations from the Balkan area. E-M123 and its daughter haplogroup E-M34 originated in the Near East in prehistoric times. As for haplogroup J, most Greeks (22.8% Greeks/14.3% Macedonian Greeks) belong to J-M172 and its subclades which is associated with Neolithic population movements. Only 1.8%/2.2% of Macedonian Greeks/Greeks belonged to haplogroup J-M267 which could potentially (althought not certainly) reflect more recent Near Eastern admixture.
Thus, at present, in a total of seven studies, in which 925 Greek males were tested, one HG16, one HG28, one HG10/HG36, and one haplogroup A chromosomes have been found, for a total of 0.4% possible non-Caucasoid contribution to the modern Greek male gene pool. Additionally, the latest studies [9, 10] with a more refined version of the Y chromosome phylogeny indicate that influences from the Near East and North Africa in historical times are unlikely (perhaps in the order of ~2%). Additionally, Y chromosome haplogroup R1a which is very frequent in Slavic populations (>50%) is found in only around 9.8% of Greeks, and is also found at comparable frequencies further East (10.8% in Iraq; Al-Zahery et al. [12]) indicating that its presence in Greece need not be associated with medieval intrusions by Slavic speakers. The emerging picture of Y chromosome variation in Greece indicates genetic continuity, with slight influences from neighboring Caucasoid regions and virtually no influence from non-Caucasoids.
Future studies with larger samples and more detailed founder analyses will allow us to obtain a better pictures of Y-chromosome variation in Greece, Europe and the world at large. At present, it appears that modern Europeans share many of the haplogroups, while there is also geographic structure in the distribution. With the exception of the Northeast corner of Europe, all other European populations have very small traces of extra-Caucasoid genetic input(a).
