I was recently reading a magazine (don't ask, I can't remember
) where a leading evolutionary biologist is campagning against calling evolution a theory, arguing it gives these wingnuts space to advance their "theories" of creation and intelligent design (please!). Evolution, she argues is a demonstratable scientific principle, and any "modifications" to it are in fact refinements on the principle, and not wholesale changes in a "theory".
Unfortunately, I believe she's beating a dead horse. Most evangelicals are morons who have to be hit over the head with a lead brick to be convinced that it hurts when you do that.
