Evolutionism

Evolutionism refers to the biological concept of evolution, specifically to a widely held 19th century belief that organisms are intrinsically bound to improve themselves, and that changes are progressive and can arise through inheritance of acquired characteristics. The belief was extended to include cultural evolution and social evolution. In the 1970s the term Neo-Evolutionism was used to to describe the idea "that human beings sought to preserve a familiar style of life unless change was forced on them by factors that were beyond their control"

The term is sometimes also used to refer to acceptance of the modern evolutionary synthesis, a scientific theory that describes how biological evolution occurs. In addition, the term is used in a broader sense to cover a world-view on a wide variety of topics, including chemical evolution as an alternative term for abiogenesis or for nucleosynthesis of chemical elements, galaxy formation and evolution, stellar evolution, spiritual evolution, technological evolution and universal evolution, which seeks to explain every aspect of the world in which we live.

Since the overwhelming majority of scientists accepts evolution, the term is seldom used in the scientific community. In the context of modern biology, to say someone is a scientist generally implies evolutionary views. In the creation-evolution controversy, creationists often call those who accept the validity of the modern evolutionary synthesis "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.
