Far east has Denisovans heritage about 2%, closer to Neanderthals than humans. Africans have none. I have 2.8 according to 23andme.com. So I am mixed species.
If you want to know more Google or go to DU Anthropology for the latest.
From bones like these three (Vi33.16, Vi33.25, Vi33.26) found in the Vindija cave in Croatia, scientists extracted Neanderthal DNA. Using these samples they painstakingly assembled the Neanderthal genome sequence.
More about Neanderthals
Neanderthals were a group of humans who lived in Europe and Western Asia. They are the closest evolutionary relatives of modern humans, but they went extinct about 30,000 years ago. The first Neanderthals arrived in Europe as early as 600,000 to 350,000 years ago. Neanderthals Homo neanderthalensis and modern humans Homo sapiens lived along side each other for thousands of years. Genetic evidence suggest that they interbred and although Neanderthals disappeared about 30,000 years ago, traces of their DNA between 1 percent and 4 percent are found in all modern humans outside of Africa. Apart from the curiosity of finding what percentage of a modern human's genome is Neanderthal, the information has great value for science. By comparing our DNA with Neanderthal DNA, scientists can detect the most recent evolutionary changes as we developed into fully modern humans.

(1,990 posts)So Africans whose ancestors never left Africa have no Neanderthal ancestry.

(3,908 posts)I am sure it was discussed there and perhaps when I am more alert I can try to search out what they have to say and get back to you.

(15,240 posts)They encountered other human species as they migrated out of Africa. It is theorized the male offspring of mixed species were sterile so we get our Neanderthal and other humanoid DNA from females who were not sterile. Too bad this information was not available for the crowd in Europe who formulated public policy on so called racial purity mid 20th Century.
