Okay . . . Natural Selection is the explanation for evolution . . . It's the driving force behind evolution.
Natural selection -- this website is from Berkeley and has ALOT of info on natural selection and evolution. If you look at the 'table of contents' on the left, you should find practically anything you'll need.
And if you want an example of a modern species
quote, "changing into another species," you're going to have a hard time. The thing is that evolution is gradual -- so gradual that it takes long periods of time for a population of a species to change enough to be classified as something else. It doesn't happen all of a sudden like it's one species one moment, then changes suddenly into something else. It's like a sculptor, whose job is never finished. In that sense, everything is evolving into something else, even humans!
But I suppose you're looking for something concrete, so I'll turn your attention to the platypus. It is an exceptional mammal that is shows many signs of evolution.
I don't think it "was all an accident." I think that it was driven by natural selection. (for your 'other option' option) Like Richard Dawkins said, "Life results from the non-random survival of randomly varying replicators." You look at it and think it's just an accident . . . but when you get close and start really studying it, it's all non-random.
Like I said to 'buckets,' I want proof for Creationism now, rather than arguments against evolution. Frankly, I'm getting tired of having to do your dirty work, cause I feel we're not really getting anywhere here.
