Hitler believed that the human gene pool could be improved by using selective breeding similar to how farmers breed superior cattle strains.
People had been breeding animals selectively thousands of years before Darwin; Darwin simply noticed something about how nature worked. If he'd never had the evolution idea, people would have carried on breeding better wheat and fatter pigs.
And megalominacal, genocidal dictators would still do mad and bad things.
