Modern genetic research has revealed that the majority of Turkish DNA, between 85% and 90%, does not come from Central Asia at all. It comes from the indigenous populations of Anatolia, the Caucasus, and the Levant who were already living in the region long before the Seljuk Turks arrived in the 11th century. Direct genetic input from medieval Central Asian Turkic migrations accounts for only about 10% to 15% of the average Turkish person's DNA. The rest is rooted in the same ancient Anatolian farming populations that also form the genetic backbone of modern Greeks. This is why DNA tests from companies like AncestryDNA and 23andMe frequently return overlapping Greek or Aegean components for Western Turkish users. The picture for Greeks is equally layered. A landmark 2017 study published in Nature confirmed that modern Greeks carry roughly 70% to 80% of the same DNA as the ancient Mycenaeans, who ruled the Greek mainland and Aegean from 1600 BC to 1200 BC. Those Mycenaeans themselves traced about three-quarters of their DNA to early Neolithic farmers from Greece and southwestern Anatolia, the same ancestral pool that shaped the pre-Turkic Anatolian population. What happened in Anatolia after the Seljuk conquest was largely a cultural and linguistic shift, not a population replacement. Greek-speaking and indigenous Christian communities converted to Islam and adopted Turkish identity over the Ottoman period, but their DNA stayed largely in place. Western Turks today show closer genetic proximity to Aegean and island populations, including Greeks and Cypriots, while Eastern Turks align more closely with Armenian and Caucasian ancestry. A separate 2024 study in Nature's Scientific Reports, examining the Greek Orthodox population of Lebanon's Koura district, found that even communities defined by Greek cultural and religious identity traced their genetics more strongly to ancient Anatolia than to modern Greeks, pointing to just how deep and widespread that shared Anatolian ancestral layer really runs across the Eastern Mediterranean. #Genetics #GreekHistory #DNA
