   Denisovan Genetic Legacy in Modern Oceanian Populations

   Modern populations in Oceania carry the highest levels of Denisovan DNA, estimated at 4-6% of their genome. Yale University researchers have mapped thousands of these ancient genetic variants. This inherited DNA continues to influence the immune systems of people in Near Oceania.

   What's confirmed:

   • Denisovans were an archaic human species or subspecies that lived in Asia from approximately 200,000 to 32,000 years ago.
   • Modern humans in Oceania derive approximately 4-6% of their genome from Denisovans.
   • Yale University researchers created the largest map of Denisovan-inherited DNA in Near Oceanian populations.
   • Interbreeding between archaic humans and modern Homo sapiens occurred during the Middle and early Upper Paleolithic.

   Still unconfirmed:

   • Pacific Islanders preserve the most ancient human genome.
   • The Harbin cranium represents a Denisovan.
   • Remains from six sites in China, including the 1 million year old Yunxian man, are related to the Homo longi lineage and Denisovans.

   Yale Study Maps Denisovan DNA Influence on Oceanian Immunity

   Ancient Denisovan genetic variants continue to affect the immune systems of modern populations in Oceania. A Yale University study provided a comprehensive examination of this inherited DNA. Researchers identified some of the oldest human genetics within people of Near Oceania.

   What's confirmed:

   • Denisovan DNA influences the immune systems of modern people in Oceania.
   • Yale University led a study to provide a comprehensive examination of this genetic influence.

   Still unconfirmed:

   • People of Near Oceania carry some of the oldest human genetics.

   Denisovan DNA actively shapes immune systems in modern Oceanians

   Research published June 11 in the journal Science shows that extinct Denisovan DNA continues to influence the biology of some people in Oceania. These ancient genetic variants remain active in the immune systems of modern populations. Scientists have created the largest map to date of this inherited DNA.

   What's confirmed:

   • Genes from extinct Denisovans actively play a role in the immune systems of some people from Oceania.
   • The research was published June 11 in the journal Science.
   • Over 3,100 genetic variants from Denisovans remain active in Oceanians.
   • Ancestors of Near Oceanians interbred with at least three different Denisovan groups.
   • Yale University researchers created the largest map of Denisovan-inherited DNA in Near Oceanian populations.

   Still unconfirmed:

   • Denisovan DNA is helping people in the South Pacific region fight viruses today.
   • Researchers are unsure why Denisovan DNA influences the immune systems of modern Oceanians.

   Denisovan DNA Continues to Shape Immunity in Modern Oceanians

   Research shows that genetic variants from extinct Denisovans actively influence the immune systems of some people in Oceania. Yale University researchers created the largest map of this inherited DNA to study its effects on modern biology. These ancient genes help some populations in the South Pacific fight viruses.

   • Denisovan DNA influences the immune systems of modern Oceanians.
   • Over 3,100 genetic variants from Denisovans remain active in Oceanians.
   • Yale University researchers created the largest map of Denisovan-inherited DNA in Near Oceanian populations.
   • Denisovan DNA helps people in the South Pacific region fight viruses.
