RE: Does this in any way change the validity of Darwin’s ideas about natural selection?
Well, if Darwin is correct ( that is, we all came from a chance process via random mutation and natural selection) , then we have to admit that some races are INHERENTLY more advanced in the natural selection process than others.
And if Darwin is correct, there really is nothing morally wrong with being a Nazi or being a supporter of the KKK.
In fact, MORALITY is meaningless. It’s just part of the process of evolution.
That doesn't follow at all. Race is a human construct, not a biological one, and there's nothing in the theory of natural selection to say one is more "advanced" than another.
And if Darwin is correct, there really is nothing morally wrong with being a Nazi or being a supporter of the KKK.
You seem confused about the scope of Darwin's theory. It doesn't address good, evil or morality in any way.
