Steve,
Primates have white skin. Dark skin is an adaptation to the exchange of fur for heat dissipation to assist in persistence hunting, and because it prevents solar radiation from harming not only skin but is immunosuppressive and inhibits certain natal chemistry production. White skin returns as need for vitamin D increases, and because neoteny (lighter skin) is a fertility signal – the direction of all human evolution is toward neoteny. African resists neotenic evolution because of competition, radiation, and perhaps most importantly, the disease gradient.
