The Turkic language was introduced in Anatolia at the start of this millennium, by nomadic Turk-men groups from Central Asia. Whether that cultural transition also had significant population-genetics consequences is not fully understood. Three nuclear microsatellite loci, the hypervariable region I of the mitochondrial genome, six microsatellite loci of the Y chromosome, and one Alu insertion (YAP) were amplified and typed in 118 individuals from four populations of Anatolia. For each locus, the number of chromosomes considered varied between 51-200. Genetic variation was large within samples, and much less so between them. The contribution of Central Asian genes to the current Anatolian gene pool was quantified using three different methods, considering for comparison populations of Mediterranean Europe, and Turkic-speaking populations of Central Asia. The most reliable estimates suggest roughly 30% Central Asian admixture for both mitochondrial and Y-chromosome loci. That (admittedly approximate) figure is compatible both with a substantial immigration accompanying the arrival of the Turkmen armies (which is not historically documented), and with continuous gene flow from Asia into Anatolia, at a rate of 1% for 40 generations. Because a military invasion is expected to more deeply affect the male gene pool, similar estimates of admixture for female- and male-transmitted traits are easier to reconcile with continuous migratory contacts between Anatolia and its Asian neighbors, perhaps facilitated by the disappearance of a linguistic barrier between them.

Alu insertion polymorphisms and an assessment of the genetic contribution of Central Asia to Anatolia with respect to the Balkans

In the evolutionary history of modern humans, Anatolia acted as a bridge between the Caucasus, the Near East, and Europe. Because of its geographical location, Anatolia was subject to migrations from multiple different regions throughout time. The last, well-known migration was the movement of Turkic speaking, nomadic groups from Central Asia. They invaded Anatolia and then the language of the region was gradually replaced by the Turkic language. In the present study, insertion frequencies of 10 Alu loci (A...
Whole genome sequencing of Turkish genomes reveals functional private alleles and impact of genetic interactions with Europe, Asia and Africa

Background: Turkey is a crossroads of major population movements throughout history and has been a hotspot of cultural interactions. Several studies have investigated the complex population history of Turkey through a limited set of genetic markers. However, to date, there have been no studies to assess the genetic variation at the whole genome level using whole genome sequencing. Here, we present whole genome sequences of 16 Turkish individuals resequenced at high coverage (32 × −48×). Results: We show tha...
Comparative analyses for the Central Asian contribution to Anatolian gene pool with reference to Balkans
Berkman, Ceren Caner; Togan, İnci Zehra; Department of Biology (2006)
Around 1000 ya, Turkic language started to be introduced to Turkey and Azerbaijan (Region of language replacement, RLR) in parallel with the migrations of Turkic speaking nomadic groups from Central Asia. The Central Asian contribution to the RLR was analyzed with four admixture methods considering different evolutionary forces. Furthermore, the association between the Central Asian contribution and the language replacement episode was estimated by comparatively analyzing the Central Asian contribution to R...
Turkic Cultural History: Early Postclassical (Pre-Islamic) Period
Dietrich, Richard (Humanities Institute, 2018-07-01)
The art of the Gök Türk empires and the subsequent Uighur states constitutes the earliest examples of art by Turkic peoples. Much of it exhibits a high level of sophistication in its execution and, unsurprisingly, shows the influence of neighboring cultures.
Tectonic evolution of the Cretaceous Ankara Ophiolitic Melange during the Late Cretaceous to pre-Miocene interval in Central Anatolia, Turkey
Rojay, Fuat Bora (2013-04-01)
The chaotic tectonic belt, which is distinguished in northern Anatolia, is called the - Ankara Accretionary Complex - in the Ankara region, central Anatolia. The belt is differentiated into three imbricated tectonic subbelts, namely, pre-Triassic metamorphics, Melange with calcareous blocks and Cretaceous melange with ophiolitic blocks (Ankara Ophiolitic Melange).
