Interestingly, I just saw a program in which scientists posed the question, "Was Darwin Wrong?"
They took points which Intelligent Design promoters use to claim that Evolution is wrong, and tried to refute them. In each case, there is ample scientific evidence to show that Darwin was not only not wrong, but was spectacularly right, especially considering the times in which he lived.
On the other hand, Darwin has little to say about morality, while the Bible, and other religious texts, are filled with moralistic tales. For better or worse, the Ten Commandments, in one form or another, form the basis for much of the modern world's laws. And scientists are learning that there is much in the Bible, specifically which is at least based on historical fact. But I think most people would agree that trying to apply the antiquated morality plays of the Bible to our own era can be dangerous, if not just plain silly!
