The point was that Hitler mentions natural selection in his book Mein Kampf: "Nature selects the best from an abundance of single elements and stamps them as fit to live and carry on the conservation of the species."
The subtitle of The Origin of Species was "The Preservation of Favored Races in the Struggle for Life". This sounds like racism to me. Do you want to address this issue or are you going to side step it again?
In The Descent of Man, did Darwin claimed that certain races, such as blacks and Aborigines, were inferior and that in due course, they would be eliminated and disappear in the struggle for survival?
Did Darwin say this?:
“At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate and replace throughout the world the savage races."
