The question of Darwin and Nietzsche is so confused it is hard to get it straight.
Here’s a bit from William Jennings Bryan:
I want to show that Nietzsche did praise Darwin. He put him as one of the three great men of his century.And he put Darwin among the three great men, his supermen were merely the logical outgrowth of the survival of the fittest with will and power, the only natural, logical outcome of evolution.
