Charles Darwin establishing evolution? 

Charles Darwin theorized or came up with the theory of evolution. Changing it back to "established" is both biased and untrue. The reason I change it back is because it is incorrect. Only pure ignorance compels people to say that he "established" anything. The definition of "established" is an accomplished fact. You cannot say that the theory of evolution is a fact, because, after all, it is still a theory.
You people please stop changing my editing back. Thanks.
