Yup. I've read three books on the San Bushmen. They are not 'black' Africans, they are Asian and their children even have Mongol spots.
The ancient Egyptians mentioned them in their glyphs and I even saw one reference that they may be the Leprechauns of Irish legend. The female Bushmen are physically 'different' in that they have an 'apron' (skin) over the genital area, this was also mentioned by the Egyptians.
All the other races in Africa refer to the Bushmen as the 'ancient ones'.
The Hottentotts, did also. I have found it passing strange, that the loosers live on the edge, the nexis seems to be Central Asia, alot of strange stuff seems to have happened out there.
