Yesterday I was wandering though the National Botanic Gardens and came across a butterfly that took my eye. It had brightly coloured wings, but when it landed its wings closed and the underside looked very much like a dead leaf. Now in an evolutionary sense this seems explainable. The wings of the butterfly would be that way as to attract a mate, and the underside would be a camouflage again predators. There would be selection in both directions.

I wonder how Jerry Fodor explains that.
