But it's equally foolish not to acknowledge that all statements are subject to revision, including scientific ones. History is replete with examples. We don't need to be experts in evolutionary biology to know that.
Slimboyfat, let me put in the first revision. Just because information gets refined and knowledge expanded, it does not mean that old information becomes totally invalid. Newton is just as valid today as three hundred years ago. Sure its been refined, but it has not been discarded. Darwin made many conjectures about evolution, and he has turned out to be more right than wrong on many occasions.
