Darwin = Darwinsim?

As we dig deeper into Darwin's theories and writing, I couldn’t help but notice was our read on Darwin right? People interoperate things differently, who are we to state Darwin’s theory as the define theory of the nation? In some way or another, I feel that even Darwin, himself, has no idea how his theory would be drill on this much. In my belief his theories are just one of the theories not THE theory about evolution. He had concluded his idea based on his observation with the nature, as many had already said he is naturalist. As Shaw declared, Darwin is not the original theory about evolution. The reason why people believed in Darwin is because Darwin’s theory was easier to understand. “Darwin becomes tedious in the manner of a man who insists on continuing to prove his innocence after he has been acquitted.”(Shaw, P.46) As Darwin repeats himself over and over again, people become convinced with the idea and justify his duplication as the reason of his statement. Yet, can his duplication of words really be induced? So as we go on to say an idea is provable or/and doubtful, we left with only one question. Is Darwin’s idea about evolution a theory or a fact?
