I didn't want this thread to turn into a big discussion, but since you asked a question... Even though I doubt that that any scientific theory is 100% correct right now, the theory of evolution has never undergone a change so drastic as to render previous versions of it completely "wrong."
That would depend on what needed to happen to make it wrong.
Like for example, Raptors, going from Lizard like, bumped skin, reptiles, to feather covered bird like animals. Would be a bit of a major change in the entire way the system should have been looked at. However, the "Theory" did not even receive a so much as a casual glance, and the "Concept" remained unchanged, the story just was modified to some how fit Raptos into the Bird Group, and say "Well that was the way it was supposed to go"
However, unless people keep up, constantly on the data, or the changes and look at what has been said, and what is said now about the process, then they remain in the sate of illusion that it is "Constant" and it is supported.
In this case, You do not believe the "Theory of Evolution" you just accept the "Concept of Evolution"
The two are not the same, because the "Concept of Evolution" can not be proven false ever, no matter what is found.
The "Theory of Evolution" states that "This is the way it happened" this is only looked at by some in a microscope level, IE: The Evolution of Man, and to them, that is "Evolution" however.
Grasp this for a moment. Every foot of our planet has life teeming though it, each and every one of those life forms has to have "Evolved", in this sense, we have so very little evidence.
The theory makes testable predictions that no competing scientific theory (that I know of) can match, and I think that's what makes me believe that, even if its every detail isn't right at the moment, our body of scientific knowledge is at the very least verging on an answer.
I believe you are confusing Adaptation, with Evolution. This a common mistake, many times people use the term Evolution, but when you look at what was done, it was selective breeding, or forced Adaptation. I may be wrong, in this. But that has been my experience when dealing with people , they confuse one for the other.
Let me show you something. This is just for fun, no debate or nothing, just something to show, to answer your own questions, as to why some of us don't believe.
If this makes you feel uncomfortable, or anything, ya know, just let me know, I don't want to pressure you or anything at all, just want you to see a few things, maybe help you understand things from my side of the fence. No pressure, no rush, if you don't feel like answering, or anything at all, it's all good. This is just for fun anyway.
Tell me what you think.
This is the skull of an animal that we have found, now I want you to look at the heavy under slung jaw, the cheek bones are quite thick, and the head is very round on top.
Now, we have found another skull, that looks very close to this skull, but with some major differences, however you can see clearly that the second skull comes from what can only be considered something that this first animal evolved from, we know the origin of the skulls and the skull below is older by quite a bit of time.
Notice how the Jaw is more inline to the skull, also notice how the lower teeth are not as pronounced as the skull above. You will see they share very common features, the high forehead (also this one has a slightly less projection on the to of it's head), the cheeks, even the back teeth are very close to each other.
Tell me what you think? Do they look like two separate species?
God Bless
