Darwin's Origin of the Species was quite controversial when it was first released because many people did not believe in evolution. Darwin's theory was that of natural selection, which meant that organisms possessed a varied ability to survive and procreate. Those having characteristics which enabled them to overcome obstacles or predators-- or other issues--and survive and procreate were named for obvious reasons the "survival of the fittest." That simply meant that those organisms having the strongest survival idiosyncrasies would win out over those not possessing such survival DNA and would live and procreate and become even stronger, in other words, survival of the fittest is a simple example of evolution through strength.
There was so much controversy about this theory there was even a movie released about it called "Inherit the Wind"starring Spencer Tracy as famous attorney Clarence Darrow. In both real life and the movie Darrow defended a Tennessee school teacher for teaching Darwin's theory. The outcome was that the teacher and Darrow lost the trial, but the teacher was fined only $1.00.

The developers of the theory of evolution by natural selection were Charles Robert Darwin and Alfred Russel Wallace.
There is no " theory of evolution " as evolution is a fact. The theory is; the theory of evolution by natural selection and explains much about the fact of evolution. Charles Robert Darwin and Alfred Russel Wallace come up with the theory of evolution by natural selection, though natural selection is a phrase coined by Darwin.
