Evolutionism

In the creation-evolution controversy, those who accept the scientific theory of biological evolution by natural selection or genetic drift are often called "evolutionists", and the theory of evolution itself is referred to as "evolutionism" by creationists. This label is used by creationists to suggest that evolution is similar to other "isms", such as Creationism, Evangelism, Judaism, Socialism, Communism, Capitalism, Nationalism, Catholicism. In this way, creationists bolster their claim that the scientific theory of evolution is a belief, dogma, ideology or even a religion, rather than a scientific theory. The terms "evolutionism" and "evolutionist" are rarely used in the scientific community as self-descriptive terms.

"Evolutionism", is defined by the OED as " [t] he theory of evolution, evolutionary assumptions or principles". Creationists tend to use the term evolutionism in order to suggest that evolution and creationism are equal in a philosophical debate.

Development of usage
Anthropologists and biologists refer to "evolutionists" in the 19th century as those who believed that the cultures or life forms being studied are evolving to a particular form. (see Platonic form). Very few scientists today, if any, believe that evolution in culture or biology works that way, and serious discussions generally take caution to distance themselves from that perspective.

Evolutionary biology explains biotic changes in terms of internal processes and gradual development as a natural progression of previously existing lifeforms. Evolution neither denies nor requires a role for divine intervention. Before the 19th century there were a number of hypotheses regarding the evolution of all material phenomena: suns, moons, planets, earth, life, civilization, and society. The number of hypotheses being propounded increased dramatically in the middle of the 19th century.

In modern times, the term evolution is widely used, but the terms evolutionism and evolutionist are rarely used in scientific circles to refer to the biological discipline. The term evolution was popularised during the 19th century by Herbert Spencer to mean cultural evolution; i.e. the improvement of cultures (see History of the theory of cultural evolution) &mdash; it was only later that it acquired its biological meaning. Advocacy of such theory was called evolutionism.

Scientists object to the terms evolutionism and evolutionist because the -ism and -ist suffixes accentuate belief rather than scientific study. Conversely, creationists use those same two terms partly because the terms accentuate belief, and partly perhaps because they provide a way to package their opposition into one group, seemingly atheist and materialist, designations which are irrelevant to science.
