A landmark paleogenomic study published this week has successfully sequenced the DNA of remains found in the lime-rich caves of Meghalaya. The analysis of these 8,000-year-old skeletons provides the first concrete genetic evidence of the initial migration waves of Tibeto-Burman speaking populations into Northeast India. The study suggests these early settlers brought unique agricultural techniques that were later adapted to the region's high-rainfall climate.
The findings indicate a complex interaction between these migrants and the indigenous Austroasiatic-speaking hunter-gatherers, leading to a unique genetic mosaic that defines the modern-day populations of the Seven Sister States. This research provides a vital missing link in understanding the prehistoric human movement across the eastern corridors of the Indian subcontinent.
