In the creation-evolution controversy, those who accept the scientific theory of biological evolution by natural selection or genetic rift are often called "evolutionists", and the theory of evolution itself is referred to as "evolutionism" by creationists. This term is used to suggest that evolution is an ideology such as creationism and other "-isms". In this way, creationists support their claim that the scientific theory of evolution is in its basics a belief, dogma, ideology or even a religion, rather than a scientific theory. The basis of this argument is to establish that the creation-evolution controversy is essentially one of interpretation of evidence, without any overwhelming proof (beyond current scientific theories) on either side. The terms "evolutionism" and "evolutionist" are rarely used in the scientific community as self-descriptive terms.
