But producing different breeds of cats isn't evolution at all. It is simply selecting for particular characteristics already inherent in the organism. Speciation as you are describing it isn't evolution in the general sense either. If organisms diverge into separate species, it is because they LOSE genetic information and are no longer to breed with their original species. It is NOT adding new information.
Evolution would require adding wings, for example, instead of front legs on a mouse or rat to produce a bat. Where does the new genetic information come from?
And since when is the ability to prove something wrong considered science? Seems like bad logic to me. If I can prove that the earth is not flat, then it would be bad science to insist it is flat. Therefore, if I can prove that evolution can not occur, does that make it bad science to insist it did occur? Seems like a good argument to me.
