How Did Tigers Get Eye Spots on Their Ears? Hint: Not What this Creationists Thinks

A creationist on Facebook posted an image of a Bengal tiger and asked: how could those eye-spot markings on its ears have evolved gradually if they only work when fully formed? It's a classic irreducible complexity argument — and it runs into serious problems, starting with the fact that there are at least three competing scientific hypotheses for what those markings actually do. I walk through each one, explain how natural selection can build a feature incrementally even without a finished "eye" shape, and then turn the argument around: under the young-earth creationist model, the ancestor cat on Noah's Ark had to somehow give rise to 40-plus living cat species with wildly different ear patterns. If Jason wants a step-by-step evolutionary pathway, I'd like one too — only his has to happen in a few centuries instead of millions of years.
