No "dodge" from me, but your ridiculous argument is the very definition of "dodge".
In fact, every animal is a "mutated animal" which has often "changed species" over many millions of years.
Or to put it another way: no animal today is the same as its ancestors were millions of years ago.
So let us begin here: the very word "species" is a total construct, which means only what scientists say it means, and has itself, uh, "evolved" over time.
If you look up the term "biological classifications" you will find that they begin at the top with Domain, Kingdom, Phylum, Class and at the bottom end: Genus, Species, Sub-Species & Breed.
Breeds & Sub-species readily interbreed (i.e., dogs), while species normally do not, and different genera cannot interbreed naturally.
That very generally is the criteria which define those terms.
One of my favorite examples is Zebras, which all look alike to me, but on close DNA analysis turn out to have over a dozen different breeds and sub-species within three different species and two different genera.
DNA analysis shows, and fossils support that those Zebras with the most similar DNA have the most recent common ancestors, and those in different species or genera have very distant past common ancestors.
The general rule is: the more similar their DNA, the more likely they are to interbreed, making them related sub-species.
But the more different their DNA, the less likely to naturally interbreed making them separate species and genera.
Of course, your religious beliefs may force you to refuse to see "evolution" in that data.
But science, by definition, cannot refuse to see what is obviously there.
