Description: Analyzes and discusses the emergence of color differences in humans on the basis of the "melanin theory." Shows how differences in the amount of melanin in the body promoted a natural selection of dark and light skinned people in equatorial and northern temperate zones respectively, by determining their relative capacities to absorb ultraviolet rays for Vitamin D production and to resist the burning effect of intense sunlight. Indicates that modern science has virtually overcome the natural forces that have brought about color differences.
