Yes? At what point does it stop being a pig? More importantly, why should it matter what we call it, as long as its ancestor was a pig but it now has wings? Is this not exactly the sort of thing you think ID is required to accomplish, and is in fact your chosen hallmark of ID?
No, of course not. It merely, by your reasoning, entails that similarly odd transformations are what we expect to see, just not any particular one.
Ah, so we’re back to whales? But your problem here is that the transition from fish to whale is amply documented in the fossil record and involves fairly small steps, just the sort of thing you claim is not what to expect from ID.
