Rick Santorum, Republican Senator from Pennsylvania, stuck his foot in his mouth during an interview on NPR this morning (August 4, 2005). I don't suppose it's his fault, he's just speaking from his religious indoctrination instead of using independent thought.
The interviewer asked what he thought about President Bush's recent statement that Intelligent Incompetent Design should be taught in schools. Rick started off well enough: he said that Intelligent Design shouldn't be taught in science classes because it isn't scientific. Then he started munching on his big toe: he said that the evidence against the Theory of Evolution should be taught along with the evidence in favor of it.
Sorry, Rick, but there simply isn't any evidence against the Theory of Evolution. Many refutes have been attempted, but every genuine attempt to scientifically show that Evolution doesn't happen has failed. There are still unanswered questions, but there is no contrary evidence.
He reasoned that we need to look at the evidence against Evolution because, according to the Theory of Evolution, mankind has no purpose: we're just a "mistake". It's impossible for the evolution of humanity to be a mistake, Rick. A mistake is doing something wrong; setting out to do one thing and doing something else instead. The process of Evolution has no target, so it can't go to the wrong place. An Intelligent Designer could make mistakes, but an unintelligent process like Evolution can't.
Does humanity have a purpose? From an evolutionary standpoint, successfully reproducing and expanding into new environments makes a species a "success", but species also change in the process. No, if humanity has a purpose, we need to define it for ourselves, but it need not be incompatible with evolution. Creating and maintaining a secure and comfortable living environment for ourselves and our fellow human beings is a realistic goal that I think anyone could agree to pursue.
