Evolutionary biologist is a commonly used description or title.<quoted text>
Obviously, the latter. But the term "Evolutionist" suggests a philosophy or ideology that is based on Evolution science.
From WordWeb: evolutionist: a person who believes in organic evolution.
I'm not sure what term that scientists use to describe themselves, but I'm sure it has SOME Greek or Latin in it to make is sound special! Either way, I'm interested in the facts. The conclusions are not absolute.
One can maintain their personal ideologies and beliefs while accepting the facts of evolution. Much the same way that one can accept the fact that the Earth orbits the sun and not the other way around without destroying ones primary beliefs.
