Let's just pretend this was true (it isn't, since he was a Bible-believing Christian who was more interested in eugenics, not evolution) it would still have no bearing on the validity of evolution. Hitler was fond of the theory of gravity too. So well done for being stupid enough to invoke Godwin's law.Adolph Hitler has written that the Aryan (German) race would be the leader in all human progress. To accomplish that goal, all “lower races” should either be enslaved or eliminated. The theory of evolution and its “survival of the fittest” philosophy had taken root in Hitler’s warped mind.
There are no "lower races" in evolution. All this shows your education on the subject is at the very least 100 years out of date.
