Your answer is a great example of someone who has only a superficial knowledge of evolution, your own quote highlights what you are missing!
Change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift. (my emphasis)
It is precisely the sort of generational changes (or adaptation) that you are talking about that eventually lead to new species, evolution does not state that one such change makes a new species.
If you were a scientist you would be wondering what happens to those changes over time and the effect they have on the classification of those species.
With all your expertise how would you suggest we positively identify antibiotic resistant bacteria?
You still haven't answered either of my previous questions.
