Step-by-step explanation:
The conflict between Christian fundamentalists and advocates of natural selection is often associated with the scientific concept of Evolution.

Christian fundamentalists, who adhere strictly to a literal interpretation of the Bible, often reject the idea of evolution because it conflicts with their belief in creationism.
