I think this is precisely what "RightWingProfessor" had in mind when he stated in several threads that biology, in the absence of a central organizing principle such as the Theory of Evolution, amounts to not much more than an exaggereated version of bird-watching: "Hey! look; it's one of those!" And "Ooooo; there's one of them...." This is, as you have correctly characterized it, the intellectual equivalent to cataloging the junk you collect in the garage or attic.
Now that I think about my father's garage, I recall that he was also a creationist. We didn't discuss such issues all that much.
