It's got very little to do with a lack of scientific knowledge, Sam - it's got a lot to do with teaching in a way that doesn't explain the science properly. F'rinstance, I'm not educated to science undergraduate level yet even I know that the Theory of Evolution says humans and the great apes share a common ancestor. In the faith school in Dawkins' programme, the teacher said that according to the Theory of Evolution, humans were descended from chimps. She also said that the school's pupils were presented with all the evidence and left to make up their own minds independently. All sixty pupils in that year independently decided to reject the Theory of Evolution.
