Non-Africans carry up to 2% Neanderthal DNA from ancient interbreeding. Melanesians, Aboriginal Australians, and Papuans carry higher Denisovan DNA. Bacho Kiro cave individuals had highest Neanderthal ancestry among early humans from 5-7 generations back. Zlatý kůň skull shows Neanderthal ancestry just 2,000 years prior at 45,000 years old. Long Neanderthal DNA segments indicate recent interbreeding. Interbreeding exceeded prior estimates. Bacho Kiro remains genetically closest to modern East Asians and Native Americans, not Europeans. Zlatý kůň shows no genetic continuity with later Europeans after 40,000 years ago. Africans lack Neanderthal DNA. Early humans migrated to Europe with fresh Neanderthal admixture.
