Evolutionism

biologists accepts evolution. Those who accept the validity of the modern evolutionary synthesis are called "evolutionists" and the theory itself as "evolutionism." Some creationists and creationist organizations, such as the Institute of Creation Research, use these terms in an effort to make it appear that evolutionary biology is a form of secular religion.

Modern use
In modern times, the term evolution is widely used, but the terms evolutionism and evolutionist are seldom used in the scientific community to refer to the biological discipline as the term is considered both redundant and anachronistic, though it has been used in discussing the creation-evolution controversy.

The Institute for Creation Research, however, in order to treat evolution as a category of religions, including atheism, fascism, humanism and occultism, commonly uses the words evolutionism and evolutionist to describe the consensus of mainstream science and the scientists subscribing to it, thus implying through language that the issue is a matter of religious belief. 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. Creationists tend to use the term evolutionism in an attempt to suggest that the theory of evolution and creationism are equal in a philosophical debate.
