Denisovan DNA Discovered in Modern Human Populations
c. 50,000-30,000 BCE · Prehistoric
Between approximately 50,000 and 30,000 years ago, interbreeding occurred between Denisovans and ancestors of modern humans in Southeast Asia and Oceania. Genetic studies show present-day Melanesians, Aboriginal Australians, and some Filipino populations carry up to 6% Denisovan DNA. Evidence suggests at least two distinct Denisovan lineages contributed to the modern human genome through multiple interbreeding events. Denisovan genes contribute to high-altitude adaptation in Tibetans and immune system functions in Papuans. Denisovan genetic material spans from Siberia to Southeast Asia and Oceania.

The migration that occupied Madjedbebe carried Denisovan genetic ancestry into Sahul, acquired via interbreeding in Wallacea; this ancestry persists in modern Aboriginal Australian and Melanesian populations and is detectable only because the founding migration physically delivered it across the Wallace Line Madjedbebe Rock Shelter Dated to c. 65,000 BCE
The Denisovan genome sequence established the genetic markers that enabled researchers to identify Denisovan ancestry in modern populations, particularly in Melanesians and Southeast Asians Discovery of Denisovans: A New Human Species
