Sheep was among the first domesticated animals, but its demographic history is little understood. Here we present combined analyses of mitochondrial and nuclear polymorphism data from ancient central and west Anatolian sheep dating to the Late Glacial and early Holocene. We observe loss of mitochondrial haplotype diversity around 7500 BCE during the early Neolithic, consistent with a domestication-related bottleneck. Post-7000 BCE, mitochondrial haplogroup diversity increases, compatible with admixture from other domestication centres and/or from wild populations. Analysing archaeogenomic data, we further find that Anatolian Neolithic sheep (ANS) are genetically closest to present-day European breeds, and especially those from central and north Europe. Our results indicate that Asian contribution to south European breeds in the post-Neolithic era, possibly during the Bronze Age, may explain this pattern.

Archaeogenetic analysis of Neolithic sheep from Anatolia suggests a complex demographic history since domestication Yurtman, Erinç; et. al. (2021-11-01) Sheep were among the first domesticated animals, but their demographic history is little understood. Here we analyzed nuclear polymorphism and mitochondrial data (mtDNA) from ancient central and west Anatolian sheep dating from Epipaleolithic to late Neolithic, comparatively with modern-day breeds and central Asian Neolithic/Bronze Age sheep (OBI). Analyzing ancient nuclear data, we found that Anatolian Neolithic sheep (ANS) are genetically closest to present-day European breeds relative to Asian breeds, a ...
Archaeogenomic analysis of genetic and cultural interactions in Neolithic Anatolian societies (NEOGENE) Somel, Mehmet; Atakuman, Çiğdem; Sürer, Elif(2023) The Neolithic Transition in the Near East (c.10,000-6,000 BC) was a period of singular sociocultural change, when societies adopted sedentary life and agriculture for the first time in human history. This project will jointly use genomic and quantitative cultural data to explore Transition societies’ organisation, interactions, and their social and demographic evolution in time. (1) We will start by dissecting social structures within Neolithic communities in Anatolia, studying the role of kinship, postmari...
Evolutionary relationship among three native and two crossbreed sheep breeds of Turkey: preliminary results Soysal, MI; Koban, E; Ozkan, E; Altunok, V; Bulut, Z; Nizamlioglu, M; Togan, İnci Zehra (2005-05-01) The Turkish native sheep breeds, possibly being the neighbours of the earliest domesticated sheep populations, might be harbouring important genetic characteristics to be employed in the future for the improvement of sheep breeds. In order to design a conservation strategy, their genetic diversities must be determined. In the present study, based on three microsatellite loci, the genetic diversity of the Kivircik, Awassi, Akkaraman breeds (native) of Turkey as well as two of their crossbreeds Turkgeldi and ...
Mitochondrial DNA Diversity of Modern, Ancient and Wild Sheep (Ovis gmelinii anatolica) from Turkey: New Insights on the Evolutionary History of Sheep Demirci, Sevgin; Bastanlar, Evren Koban; Dagtas, Nihan Dilsad; Pişkin, Evangelia; ENGİN, ATİLLA; Ozer, Fusun; Yuncu, Eren; Dogan, Sukru Anil; TOGAN, İNCİ ZEHRA (2013-12-11) In the present study, to contribute to the understanding of the evolutionary history of sheep, the mitochondrial (mt) DNA polymorphisms occurring in modern Turkish native domestic (n = 628), modern wild (Ovis gmelinii anatolica) (n = 30) and ancient domestic sheep from Oylum Hoyuk in Kilis (n = 33) were examined comparatively with the accumulated data in the literature. The lengths (75 bp/76 bp) of the second and subsequent repeat units of the mtDNA control region (CR) sequences differentiated the five hapl...
Preschool children's use of perceptual-motor knowledge and hierarchical representational skills for tool making Gönül, Gökhan; Takmaz, Ece; Hohenberger, Annette Edeltraud (2021-10-01) Although other animals can make simple tools, the expanded and complex material culture of humans is unprecedented in the animal kingdom. Tool making is a slow and late-developing ability in humans, and preschool children find making tools to solve problems very challenging. This difficulty in tool making might be related to the lack of familiarity with the tools and may be overcome by children's long term perceptual-motor knowledge. Thus, in this study, the effect of tool familiarity on tool making was inv...
