Well it is bullshit,because there is probably no such thing like races now. At least not binded to the color of the skin. You could treat neandertals like another race of humans,but differences between white,black and yellow are quite small

There are of course genetic differences,but the point is:

Many populations of Africa are genetically more separate from one another than, for instance, a European person and themselves. Same for some populations of Asia (like the Tibetans) that have historically lived in isolation: on the surface, they may look more closely related to Mainland Chinese people, but the Chinese person is likely to be more similar to, say, an American, in their genetic makeup.

Black or White ? Reality is even more strange - they are mix with Denisovians. The same orgin has EPAS1 sherpa gene modifying blood to let them live and function above 4000 m over see level easier than ordinary people.
