SRINAGAR: In a groundbreaking study published in Nature, scientists have, for the first time, extracted and decoded ancient DNA from human remains found in the Kashmir Valley, revealing a genetic story that stretches from the Neolithic to the Medieval period.
The study, which examined mitochondrial genomes, DNA passed down through the maternal line, from burials at Burzahom and nearby sites, paints a vivid picture of continuity, migration, and cultural exchange in one of South Asia’s most storied landscapes.
The team, led by geneticists including Kumarasamy Thangaraj and Niraj Rai, sequenced mitogenomes from four individuals belonging to three distinct time periods. One burial dated to around 2000 BCE, from the Neolithic phase of Burzahom, carried a lineage known as M65a, a genetic marker still found among modern Kashmiris. This discovery suggests an unbroken maternal ancestry in the valley lasting more than four millennia, a rare continuity in a region often seen as a crossroads of ancient migrations.
Another burial from the Megalithic phase, also unearthed at Burzahom, revealed haplogroup U2b2, a lineage with even deeper origins stretching back about 8,000 years. This genetic signature links Kashmir’s prehistoric population not just to neighbouring parts of northern India but also to regions of Central Asia, suggesting that the early inhabitants of the valley were part of a wider web of prehistoric movements and interactions.
But by the Medieval period, the genetic story becomes more complex. Two individuals from this era carried very different maternal lineages, one of them, M30, common in South Asia, and another, W4, more frequently found in West Eurasia and Central Asia. The latter points to possible contact, intermarriage, or even migration from regions once part of the Bactria–Margiana Archaeological Complex, the Bronze Age civilisation that thrived across modern-day Turkmenistan and northern Afghanistan.
Taken together, the findings present the first direct genetic evidence of Kashmir’s long and layered human history. The Neolithic and Megalithic genomes reflect deep local roots, while the Medieval ones record the valley’s growing exposure to Central Asian influences, echoing what archaeologists have long observed in its material culture. Pottery designs, tool-making traditions, and burial practices from Burzahom and the Swat Valley show striking similarities, and the genetic data now confirms that these were not just cultural exchanges but involved real human movement.
The authors of the study note that the maternal continuity in Kashmir is particularly remarkable given the valley’s strategic position along ancient trade and migration routes. “The Neolithic sample genetically belongs to the mtDNA lineage M65, which is also present in the modern mitochondrial gene pool of Kashmir,” the paper states. “This reflects maternal genetic continuity in this region over the millennia.” At the same time, they add, “In the Medieval period, genetic evidence of links with the Swat Valley as well as Central Asia suggests large-scale demographic shifts in the region.”
For Kashmir, these findings do more than map its ancient genetics; they reinforce its image as both a cradle of early civilisation and a corridor of cultural contact. The DNA of those who once lived and died in Burzahom has carried across thousands of years, whispering of roots that run deep, and of journeys that reached far beyond the Himalayan rim.
