Why did butterfly metamorphosis evolve?
It’s likely your question re metamorphosis can’t be explained by evolution. Not many things can be. There are an infinite number of such questions that can be posed, so the more appropriate response is to suggest that evariste become more intimate with evolution. Illustrating a specific pathway from a progenitor life form to a current one necessarily incorporates a lot of speculation, but comprehending the process, in general, doesn’t. This, apart from sounding quite condescending, is blanket doublespeak from the evolutionary camp. It might help, evariste, to remember that evolutionary theory is pretty weak scientifically; the reason it enjoys so much support is because so far we’ve failed to come up with anything better. Monkeys > humans seems plausible if you stand back and squint at it, but even that is missing huge blocks of critical evidence which cause the theory to stop far short of being definitive. FauxScot’s answer is another way of saying “evolution can’t explain everything
