A landmark paleogenomic study published this month has analyzed the DNA of remains found in the ancient burial mounds of the Brahmaputra Valley, dating back to 1000 BCE. The results confirm a massive genetic exchange between the local Austroasiatic-speaking populations and Tibeto-Burman migrants much earlier than previously hypothesized by historians.
The findings suggest that the northeastern corridor of India was a vibrant 'genetic melting pot' that facilitated the spread of advanced rice cultivation and metallurgy. This research provides a new scientific foundation for understanding the complex ancestry of the diverse ethnic groups inhabiting modern-day Assam and Meghalaya.
