It's a perfect example of evolution: an earlier form (a bird with the capability of flight) evolves into a later form (a flightless animal) but it still retains the telltale wing structures!

Evolution takes many twisty pathways (the recurrent laryngeal nerve, blind cave fish that still have eyes, whale hip bones, etc.)

If living creatures had been designed, rather than evolving, why would they have such vestiges designed into them?

So if I read you correctly, you're saying that "devolution" means descendants of earlier creatures may be substantially different from those earlier forms? So speciation does occur?

Also, doesn't this mean your answer to the original post is no, the kiwi's wings were NOT designed, they evolved from an earlier, flight-capable form?

How can you accept speciation and not accept that, for example, humans are descended from earlier primates that were a different species?
