The evidence shows that evolution explains the creation of new species. Over time, many changes accumulate, which can create radical changes. What's to stop that? Certainly not irreducible complexity, because what has been thought to be IC has been shown to not be IC. Things can get re-purposed.I believe that most people don't have a problem with evolution per se. Let's face it, natural selection is a viable force. We have seen it. If there is artificial selection (methodical selection according to Darwin) then there is natural selection where changes in the environment makes the selection along with mutations that allows species to out perform their peers. We just don't give evolution credit for the unbridled power that darwinist's do for turning fish into quadrupeds and then apes into humans.
