Isolated populations evolve differences gradually as they adapt to the environment

A theory or speciation can be diffulcult to prove because either the scientist does not know a part of why something happens or in some cases, like the big bang, you can not go back 14 billlions years to witness it. That means that we are not 100% sure how it happened because we had no witness and we do not the the scientific technology to re-act it.
The theory of evolution by natural selection explains how adaptive change may lead to speciation,\. As any good scientific theory it explains much but not everything. I seriously doubt, except in an ultimate sense, that you can explain why Gothic literature is now popular with evolutionary theory.
That's true. A theory es exactly that - theory... Results from experimentation can prove or disprove a theory.
True.
Caralous linnaeus theory is accepted theory of speciation

That the theory of evolution by natural selection fits the facts of evolution. The theory of evolution by natural selection is based on myriad lives of converging evidence and is the best explanation we have for the adaptive changes leading to speciation in populations of organisms.
