Denisovans, Neanderthals, and multiple human species intermixed with Homo sapiens. Denisovans discovered in 2010 from a finger bone in Cave del Valle, Cantabria, Siberia Denisovan range stretched from Siberia to Southeast Asia, with a jaw fragment found in Tibet Indigenous Australians, Papuans, and Southeast Asian populations carry Denisovan DNA

Denisovans were identified in 2010 from a finger bone in Siberia's Cave del Valle, Cantabria, their range stretching to Tibet where a jaw was found. Indigenous Australians, Papuans, and Southeast Asians carry Denisovan DNA. Non-African populations retain 1-4% Neanderthal DNA from repeated interbreeding over millennia. Other species like Homo floresiensis in Indonesia, Homo luzonensis in the Philippines, and Homo naledi in South Africa add to the picture. Back-migration even returned archaic genes to Africa, while "ghost populations" remain identified only through genetic signatures.
