Darwin, Creationism and EvidenceBoth the general theory of evolution and Darwin’s particular theory of evolution by natural selection are regularly challenged by people who describe themselves as “creationists”. There are several varieties of creationism. The focus here is on what is often called “young earth creationism”: the view that the entire universe is approximately six thousand (certainly less than ten) thousand years old, and that all living species were created within the first few days of creation. Henceforth, when I speak of “creationism”, it is young earth creationism I have in mind.
