It is one of several means of producing diversity on which the several mean of selection that drive evolution can act. Darwin knew nothing of mutation and only discussed diversity (without any mechanism to produce it) and what he called natural selection. There have been many of both types of processes discovered since Darwin.
Hitler thought that Jews were dogs and needed to be killed. He believed in Darwins theory of evolution 'survival of the fittest'. He thought that the Germans were the most fit to live and the Jews and Blacks were the least fittest to live. Sick.
I answered a question like this earlier. It does not. What flood myth? There are many of them and none of them have anything to do with the theory of evolution by natural selection.
There is no such thing as "the first duck." all things on earth evolved slowly, mutation by mutation, so that they fit their environment. Things that have good mutations live and have kids, and their kids have that mutation. That's how evolution works.

This question could fit both Charles Robert Darwin and Alfred Russel Wallace in an answer as they both were British naturalists and both developed a theory of evolution by natural selection.
Nice? The theory of evolution by natural selection is the best and best supported explanation for the fact of evolution we have, but it just is and a word such as " nice " would not always fit theory. Google Ichneumon wasp to see that natural selection is not always " nice. "
The church opposed his views. The church said that god created everything as they are now. Darwin believed in evolution. Evolution, by the way, is the scientific theory that everything adapts to fit its environment.
living things over produce variation among offspring struggle to survive desirable traits are more fit.

One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
We don't use the word "true" to describe scientific theories. They either fit the facts or they do not. Darwin's theory of evolution fits most of the observed facts, and does so beautifully. A theory is useful if it makes successful predictions. Darwin's theory has absolutely zero to do with belief in God. The Catholic Church does not hate God, yet endorses the view that evolution has occurred in much the way Charles Darwin described. Is there a scientific theory that better explains the evidence from paleontology, geology, anatomy, and molecular biology? No. Therefore, we provisionally accept the theory of evolution as an accurate depiction of the origin of species. Again, this has nothing to do with whether or not God exists and/or loves you. Evolution is wrong. God is true.
Darwin's explanation for the fact of evolution was better than Lamarck's explanation and fit the fact of evolution. Natural selection solved much of the species problem, but acquired characteristics did not have the empirical support and explained nothing in the end.
