Evolution, then, is a theory, one of the most influential, far-reaching and important theories ever devised. In this context, it's worth pointing out that the word 'theory' is often used in a quite different sense, to mean an idea that is proposed in order to be tested. Strictly speaking, the word that should be used here is 'hypothesis', but that's such a fussy, pedantic-sounding word that people tend to avoid it. Even scientists, who should know better. 'I have a theory,' they say. No, you have a hypothesis. It will take years, possibly centuries, of stringent tests, to turn it into a theory.

"I've got a hypothesis, that it's a demon, a dancing demon..."
...nah, something isn't right there. It doesn't fit the music.
