A comprehensive DNA study of skeletal remains from the Swat Valley in Pakistan has revealed a complex genetic history of migration and admixture. The research shows that the Iron Age inhabitants carried a mix of ancestry from Central Asian steppe groups and indigenous South Asian populations.
This study provides critical evidence for the movement of Indo-Aryan speaking groups into the subcontinent. The data suggests that genetic mixing occurred over several centuries, leading to the diverse population structure seen in North India today.
