This is about the origin of differences in appearance not their perpetuation.  This kind of selection produces feedback effects which can produce morphological differences among isolated populations that have nothing to do with adapting to different evironments.  This includes skin color. Once these isolated populations mix other forces, e.g. racism, lust, other psychological factors, etc can easily be more determinant.<
