My post, Are Turks Armenians Under The Hood?, attracted a little bit of controversy. The main criticism, which was a valid one, is that I did not sample Anatolian Greeks. A reader passed on three Anatolian Greek samples. I also added a Cypriot data set. To my mild surprise, the Anatolian Greeks and Cypriots cluster together, at the end of the Greece cline toward West Asians. Therefore, for further analysis, I pooled the three Greeks with the Cypriots.
Additionally, there are two Balkan Turk samples. Even on the PCA it’s pretty clear that they’re genetically very different from the other Turks (one of them is from what has become Bulgaria), though the shift toward East Asians indicates that Turkification is very rarely a matter purely of religious conversion to Islam and assimilation of the Turkish language (obviously it initially is for many people, but these people then intermarry with those with some East Asian ancestry).
