Summary:

- Researchers have discovered a previously unknown population of humans whose DNA was found in the genomes of people living in Oceania today.
- This mysterious population, dubbed the "Unknown Archaic Humans," likely interbred with the ancestors of modern Papuans and Aboriginal Australians tens of thousands of years ago.
- The discovery provides new insights into the complex history of human evolution and migration, suggesting that multiple archaic human species may have coexisted and interacted in the past.
