A new paleogenomic study published in Cell Reports has successfully sequenced the DNA of three individuals from a newly discovered burial site in the Chambal Valley, dating back to 2500 BCE. The research identifies a specific genetic marker previously unknown in the Indian subcontinent, which appears to represent a 'bridge' population between the Central Asian Steppe lineages and the indigenous hunter-gatherer groups of the Malwa plateau.
The findings suggest that the migration of Indo-Aryan speakers was a far more gradual and genetically diverse process than previously theorized. This 'Chambal lineage' provides the first physical evidence of a stable, mixed community that maintained high-status metallurgical traditions while integrating diverse ancestral backgrounds during the transition from the Copper Age to the Early Bronze Age.
