A person who believes in or advocates for evolutionary theory; a biologist who specializes in evolution.
From 'evolution' + '-ist' suffix meaning 'one who practices or believes.' Used since Darwin's time to describe both scientists and philosophy supporters of evolution.
Originally a charged term—'evolutionist' was sometimes used dismissively by religious opponents in the 1800s, but today it's simply a neutral label for biologists studying how species change.
