Through a careful analysis of DNA mixtures, scientists were able to trace the movements of people across the Near Eastern landscape in the early Neolithic . They found that migration into Anatolia coincided with critical developments in farming techniques and practices in that region during that period, suggesting that farmers from nearby lands were instrumental somehow in the advancement.

The scientists discovered that in the Pre-Pottery era (approximately 10000 to 6500 BC, with regional variations), farmers originally from Mesopotamian migrated to Anatolia and intermixed with the locals quite freely. About the time pottery was first invented, around 7000 BC (there is some overlap between the Pre-Pottery and Pottery eras), another wave of farmers from Mesopotamia moved into Anatolia, along with other farming migrants from the Levant

The discovery that people were entering Anatolia at the exact moment the Neolithic Revolution was accelerating is highly significant. This is certainly no coincidence, as the combined efforts of the different population groups to improve their farming methodologies would have made rapid agricultural advancement far more likely to occur.

One thing the researchers can say for sure is that the migration into Anatolia occurred on an impressively large scale. They can’t determine the precise numbers of migrants who entered, but their study found residents of ancient Anatolia in the relevant periods had a genetic heritage that included between 30 and 50 percent Mesopotamian and/or the Levantine DNA. The migrants must have been welcomed by the locals, who undoubtedly appreciated and benefitted from their agricultural theories and practices.
