What? Have you even studied natural selection? Darwin? There are so many things wrong with your statement....
There are even more things wrong with Darwin's statements:

I have studied natural selection, I stay away from Darwin.
Let's put this in a wider context:

Darwin meant "exterminate" by the process of Natural Selection.
What is wrong with that? That statement fits perfectly Darwin's hypothesis.
He referred to black people as the "savage" or "inferior" races. He knew he was wrong, because people were into egalitarianism even in his days. It was only white supremacists who could not accept that all races are equal, he believed he had some magical powers for being white. Does that sound familiar? Because it certainly does to me.
And, he was wrong. PoCs are still here, and they're here to stay, whether you like it or not =]
