Hobby anthropologist here, there's plenty of slight skeletal differences between races. Africans have prognathism, bimaxillary protrusion, and longer distal limbs for dissipating heat. They generally have shorter torsos and longer legs. Asians have fairly flatter faces to shield against the cold and and longer torsos and shorter legs to generate heat. Caucasians have big noses in general and land between Asians and Africans in regard to limb length.
