Firstly, it's title gives it away. It's just a theory. What is more it is a theory without any scientific basis or proof whatsoever. Even Darwin had problems with his own theory. Unfortunatley this has been peddled to kids thru college for years and has almost become "accepted truth" despite the problems above. Nowhere in science has a species evolved into something else. They adapt but don't change kind. The Bible even speaks in Genesis of everything according to it's kind.
