The research, as would be expected, is dense, but concludes that the mutuations responsible for blue eye color "most likely originate from the neareast area or northwest part of the Black Sea region, where the great agriculture migration to the northern part of Europe took place in the Neolithic periods about 6,000–10,000 years ago."
