Dear Peter,
I have an impression it is your own research, isn’t it? I wonder what its status is. Has it been reviewed by other biologists? Did they confirm your observations? If some of them don’t, what is the main argument against your evidence?
I would speculate that unless you understand the mechanism of the NRM you cannot conclude that it works for humans, can you.
Suppose however that the NRM has been observed, studied and the mechanism explained. I still will have doubts it took place with the humans in the past. If certain groups of humans suddenly underwent such mutations it would be remembered as the major events of their histories. They have legends telling: once we were white and then suddenly became black or once we were black and then suddenly became Mongoloids. It would be present in the legends and myths of all the peoples on the Earth.
Indeed, imagine a Viking tribe where women suddenly start giving birth to black children. Most likely the parents would simply kill the children, but even if not such an event would be most likely remembered forever.
However such legends and myths are not recorded.
