Description
J2 is a Y-DNA haplogroup strongly associated with the Neolithic spread of agriculture from the Fertile Crescent into Europe, the Caucasus, and South Asia. It is found at high frequencies among many Mediterranean and Middle Eastern populations and is often linked to ancient civilizations such as those of Mesopotamia, Anatolia, and the Indus Valley. J2a is dominant in the Mediterranean and Near East, while J2b is more common in South Asia.
Interesting Fact
J2 has been found in ancient remains from early Neolithic farming villages in Anatolia, suggesting that Neolithic farmers — not hunter-gatherers — carried this haplogroup into Europe around 7,000 BCE, fundamentally reshaping European genetic landscape.
