Estimated percentages of Archaic Hominid DNA in modern human populations:
Europeans: Approximately 1-2% Neanderthal DNA
East Asians: Approximately 1-2% Neanderthal DNA
Oceania: Up to 5% Denisovan DNA
South Asians: The exact percentage is not well-defined, but it's likely to be less than East Asians and Oceanians and consists of a mix of Neanderthal and Denisovan DNA. It might range below 1%.
Americas: Approximately 1-2% Neanderthal DNA
Sub-Saharan Africa: Approximately 2 to 19% from an unknown archaic hominin, sometimes referred to as a "Ghost Species"
