You sometimes see a bumper sticker with a picture of a fish with legs. It's a clever take-off of a Christian sticker which has a fish with the word 'Jesus' - a fish is a symbol for Jesus. The idea is, we evolved from fish. But how far would a typical fish-with-legs-decorated-Subaru driver take Darwinism? As far as it gives them a warm, fuzzy feeling, and no further.
