Let's start with the word "Darwinism"–since there's no such thing. It's a pure propaganda word invented by anti-evolutionists to make it sound as if science is just another belief system or a political group. Languages, just like species, have evolved naturally for millennia before anyone got around to describing the process, and those who work at discovering nature's laws appreciate the head start Mr. Darwin gave us, but we certainly don't elevate him to the status of an "ism" or a revered figure any more than people who believe in gravity would call themselves "Newtonists".
