200,000-Year-Old DNA Found in a Tooth, Scientists Are Stunned by What It Reveals!
Indian Defence Review••science
Key Points:
- Scientists from the Max Planck Institute have sequenced a second high-quality Denisovan genome from a molar (Denisova 25) found in Denisova Cave, Siberia, dating back around 200,000 years, making it the oldest Denisovan genome sequenced to date.
- Denisova 25 reveals that multiple genetically distinct Denisovan groups occupied the Altai Mountains, with evidence of recurrent interbreeding between Denisovans and Neanderthals, as well as admixture with an even older hominin lineage.
- The study challenges previous views of isolated Denisovan populations, suggesting complex migration patterns and multiple waves of Denisovan ancestry contributing to the genetic diversity seen in modern populations across Oceania, South Asia, and
