Description
Haplogroup L is a significant paternal lineage primarily found in South Asia, West Asia, and to a lesser extent, the Middle East and Europe. It is strongly associated with the early agriculturalists of the Indus Valley and is one of the primary genetic signatures of the Indus Valley Civilization. Its presence in Southern India among Dravidian-speaking populations suggest a long-term presence in the Indian subcontinent, potentially linked to the spread of Neolithic farming from the Fertile Crescent toward the east.
Interesting Fact
Haplogroup L is significantly more common in 'caste' populations than in 'tribal' groups within India, supporting the theory that its spread was linked to later Neolithic migrations and the establishment of organized agricultural societies.
