Notes

  • A study in Science Advances analyzed genome-wide data from 10 individuals found in a Kargil cave, dating back approximately 1,500 years.
  • Genetic analysis reveals the individuals were a mix of populations: 50% proxied by present-day North Indians and 50% closer to ancient Tibetans.
  • Genetic evidence suggests a population admixture occurred approximately 2,800 years ago, predating the Tibetan Empire.
  • Both the Science Advances paper and a separate preprint from the Birbal Sahni Institute/University of Chicago identify a third genetic component from Inner Asia.
  • The findings provide evidence of ancestral North Indian ancestry, which is a foundational component of most modern North Indian and Pakistani populations.
  • Archaeological context indicates a pre-Buddhist Ladakhi practice of burying the dead in natural caves.
  • The community lived along a trade route, which may have facilitated continuous genetic admixture.
  • Debate exists among researchers regarding the precise timing of the genetic mixing (2,800 years ago vs. 2,100-2,500 years ago) and whether the mixing occurred locally in Ladakh or elsewhere.
