Intelligence. But we digress.
I know this may shock some of you, but I gotta agree that creationism has no business being taught in a science class. Conversely, I also believe that in teaching evolution, it should be made clear that it does not explain how life began, but rather how living organisms evolve. There is a subtle difference that I think is often lost on everyone.
Of course, I do not claim to know all the finer points of evolution theory or how it is being taught, so my above statement may not reflect the current status of evolutionary theory. Maybe science does now claim to know for a fact how life began.
