We present a spatiotemporal picture of human genetic diversity in Anatolia, Iran, Levant, South Caucasus, and the Aegean, a broad region that experienced the earliest Neolithic transition and the emergence of com- plex hierarchical societies. Combining 35 new ancient shotgun genomes with 382 ancient and 23 present-day published genomes, we found that genetic diversity within each region steadily increased through the Holo- cene. We further observed that the inferred sources of gene flow shifted in time. In the first half of the Holo- cene, Southwest Asian and the East Mediterranean populations homogenized among themselves. Starting with the Bronze Age, however, regional populations diverged from each other, most likely driven by gene flow from external sources, which we term ‘‘the expanding mobility model.’’ Interestingly, this increase in in- ter-regional divergence can be captured by outgroup-f3-based genetic distances, but not by the commonly used FST statistic, due to the sensitivity of FST, but not outgroup-f3, to within-population diversity. Finally, we report a temporal trend of increasing male bias in admixture events through the Holocene.

Nationalism and religion in the formation of modern state in Turkey and Egypt until World War I Boztemur, Recep (2005-12-01) This study discusses the formation of national identity and the nation state in the modern Middle East in comparison with Turkey, one of the earlier models, of national state formation in the region. The basic aim of the study is to examine the position of religion and religious identity as the source of legitimacy in the modern state. In order to have a better understanding of the relationship between nationalism and religion in the Middle East, the study attempts to look at the development of Egyptian nat...
DNA diversity and population admixture in Anatolia Di Benedetto, G; Erguven, A; Stenico, M; Castri, L; Bertorelle, G; Togan, İnci Zehra; Barbujani, G (Wiley, 2001-06-01) 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 c...
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...
Nomadic Cultures in the Mega-Structure of the Eurasian World (Book Review) Pamir Dietrich, Ayşe (2018-07-01) Nomadic Cultures in the Mega-Structure of the Eurasian World by Evgenij N. Chernykh is a comprehensive work that examines the history of Eurasian nomadic peoples and their influence on world history and culture. Translated from the original Russian, it consists of an introduction, forty chapters organized into five parts, five appendixes, two extensive bibliographies – one for sources written before 1500, and one for modern sources - and an index. The book begins with “Part I: The Steppe Belt in the Mega-S...
The role of the Young Ottomans in the transformation of mentality in the Ottoman Empire Kaplan, Ferhat; Ertuğrul, Kürşad; Department of Political Science and Public Administration (2007) The main topic of this study is determining the role of the Young Ottomans in mentality transformation in the Ottoman Empire from the traditional one to a modern one. Their proposals aim to change three patterns of the Ottoman state and society. The relation between state and the individual is the first issue. They tried to create an Ottoman citizenry, enhanced with freedom and political rights, from a reaya. In the second step they imagined a modern society. Their proposals, which imply a secular system, a...
