These result were basically expected.
While in most places in Europe, farming was brought by migrants who were genetically similar to Anatolian farmers, in Anatolia, which was at the epicenter of the Fertile Crescent Neolithic revolution, farming developed in situ with the local population since somebody had to invent it in the first place before there could be migrant populations bringing it somewhere else.
The study also detects Mesolithic migration from Anatolia to Europe.
Anatolia was home to some of the earliest farming communities. It has been long debated whether a migration of farming groups introduced agriculture to central Anatolia. Here, we report the first genome-wide data from a 15,000 year-old Anatolian hunter-gatherer and from seven Anatolian and Levantine early farmers. We find high genetic continuity between the hunter-gatherer and early farmers of Anatolia and detect two distinct incoming ancestries: an early Iranian/Caucasus related one and a later one linked to the ancient Levant. Finally, we observe a genetic link between southern Europe and the Near East predating 15,000 years ago that extends to central Europe during the post-last-glacial maximum period. Our results suggest a limited role of human migration in the emergence of agriculture in central Anatolia.
