I think the biggest problem with the theory of evolution is that there still has been no real evidence suggesting the need for an animal or organism to become a different species entirely..how does that happen?
adaptation is a real and viewable fact..it is proveable and makes complete sense.
But just how does an organism evolve an eye? Does the eye evolve over time or as a whole piece of functioning tissue? What is the purpose of an eye that doesn't work (not having several key componenets)? Evolution doesn't seem advantageous in practive..while adaptation does...supposing that evolution is just a series of consecutive massive adaptations doesn't make sense..why does a bacteria need to evolve into a fish when it works fine as a bacteria...???
I don't know..it's complicated...but I see no reason for "evolution" to exist as a biological function other than adaptations that adjust to a currently existing species and allow it to adjust to a new environment or stress of an environment.
