The common understanding that things like fish are in a different major animal group from things like lions.

Okay, there's part of the answer: now we have some idea of what you mean by "major animal group." (But only some idea. Are wolves a different major animal group from lions? Are lizards?)

Now can you say what you mean by "transference"?

Doesn’t matter. Keep it simple. The utter lack of evidence that fish “evolved” (transferred) into mammals (or visa versa) destroys Darwinism.
