This undergraduate level paper is an examination of the argument of natural selection in evolution as put forth by Charles Darwin in his "Origin of the Species". The paper examines the argument from the geological record, biological evidence, and logical reasoning point of view. It uses these arguments to demonstrate the validity of evolution in the case against traditional views of creationism. It concludes that while evolution does not deny God, it challenges the secular community to find evidence other than faith to disprove the Darwinian theory. 6 pgs. Bibliography lists 2 sources.
