What does evolutionist mean?
An evolutionist is a person who accepts and supports the theory of evolution — most commonly Charles Darwin's account of how species change over time through natural selection. The word functions primarily as a noun, though it occasionally appears adjectivally in older writing ('the evolutionist position'). It came into prominence in the second half of the nineteenth century, when Darwin's On the Origin of Species ignited public controversy between those who accepted common descent and those who defended special creation; its natural opposite remains 'creationist'. Today the term appears most often in discussions of science education, public debates, and intellectual history, since working scientists rarely use it of themselves. A secondary, now less common sense describes anyone who applies evolutionary thinking outside biology, for example to language change or social institutions. Because it identifies a person by their stance on a contested theory, the word can sound slightly partisan, and neutral writers often prefer phrases like 'accepts evolution' over labeling someone an evolutionist.
nounA person who believes in or supports the theory of evolution, especially biological evolution by natural selection. More broadly, one who studies or advocates an evolutionary account of development in any field.
- A supporter or believer in the theory of evolution, especially Darwin's theory of evolution by natural selection.
- A scholar who applies evolutionary principles to a field beyond biology, such as language, society, or economics.
"As a committed evolutionist, she welcomed the fossil evidence that filled in the gaps of the hominid record."
"The evolutionist pointed to antibiotic resistance as natural selection unfolding before our eyes."
"Early evolutionist thinkers applied the idea of gradual change to languages as well as to species."
Regular plural; used both for individual adherents and for groups or schools of thought.
"Nineteenth-century evolutionists clashed openly with defenders of special creation."
The word's chief antonym is 'creationist' — and in the 19th century the debate between them was so fierce that 'evolutionist' was sometimes used as an outright insult.

Etymology of evolutionist
Evolutionist derives from 'evolution', which comes from the Latin 'evolutio', meaning 'an unrolling' — from 'evolvere' ('to roll out or unfold'), formed from 'e-' (out) plus 'volvere' (to roll). The English noun 'evolution' was in use by the seventeenth century for the unrolling of a scroll or the unfolding of events, and only in the early nineteenth century did it acquire its biological sense of species development. 'Evolutionist' was formed from this noun with the agentive suffix '-ist', denoting an adherent, and became widespread after the publication of Darwin's On the Origin of Species in 1859.
How evolutionist is actually used
The term is largely neutral but can carry a slightly polemical tone when used in debates with creationists; scientists more often describe themselves simply as biologists or say they 'accept evolution'. The older, broader sense applying to non-biological fields is now somewhat dated.
Easily confused with evolutionist
A revolutionist advocates political overthrow, whereas an evolutionist believes in gradual evolutionary change — often literally the opposite stance.
