Question: Why are conservatism and Darwinism traditionally at odds?
Answer: I think the traditional view of conservatives is that Darwinism, at least in the popular perspective, appeared to undermine the credibility of religious belief. The typical conservative religious view is that religion is essential to the maintenance of a decent and free society.
So, traditional conservatives tended to be suspicious of Darwinism. The claim has been made by some Darwinists that Darwin makes it possible for us to understand all of the apparent order of nature without reference to an intelligent cause, such as God, as it is traditionally understood. ... [In religion] you have to have reference to a creator to explain order. Darwinism says on the surface that we can explain creation without any religious cause.
