I hear we'll be loosing the blond hair gene within the next 100 years or so, because it is so recessive. The whole ideal behind natural selection is that life is specialized to one area, and the life best fit to survive there will. White rabbits evolved from multi-colored rabbits as the other color genes were being killed off. Natural selection doesn't promote diversity; it promotes species in an area gradually become homogenous.
