Evolutionism

Evolutionism refers to the biological concept of evolution, specifically to a widely held 19th century belief that organisms are intrinsically bound to increase in complexity. The belief was extended to include cultural evolution and social evolution. In the 1970s the term Neo-Evolutionism was used 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 colloquially 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 accept the modern evolutionary synthesis as the best explanation of current data, the term is seldom used in the scientific community; to say someone is a scientist implies acceptance of evolutionary views, unless specifically noted otherwise. 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.
