We now know that modern humans admixed with Neanderthals as well as Denisovans, an extinct hominin species, existence of which we acknowledged through genetic studies. Whilst the majority of admixture events took place in Eurasia following the out-of- Africa migrations of modern humans, there is now accumulating evidence indicating that the ancestors of modern humans also admixed with ancient hominins in Africa. An emerging question following these findings is where, when and how many times modern humans admixed with ancient hominin species. In this dissertation, I studied the genetic remnants of these admixture events, that is introgression from ancient hominin species into modern humans, in a population- specific manner. I started with discussing the importance of western Asia in terms of human evolution. Western Asia has been a major cross-roads of human population movements throughout the human evolutionary history. As such the region deserves more focused studies. Second, I investigated the Neanderthal ancestry proportions specifically in western Asia. Results revealed that western Asians carry slightly lower Neanderthal ancestry as compared to other Eurasian populations. Migrations from Africa into the region in more recent times likely diluted Neanderthal ancestry in western Asia. These results are based on point estimates of genome-wide Neanderthal ancestry for different human populations."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["A Genetic Record of Admixture Between Humans and Ancient Hominins"]}]}],"canonical_facts":{"dc:contributor":["Gokcumen, Omer","Biological Sciences"],"dc:creator":["Taskent, Recep; 0000-0003-1604-0659"],"dc:date":["2019-10-29T16:48:08Z","2019","2019-08-08 14:24:29"],"dc:description":["Ph.D.","Recent studies showed that admixture between modern humans and ancient hominin species was a ubiquitous phenomenon in the past.
