The professor is wrong. First and foremost, belief in evolution is irrelevant to most advanced courses of study in "the biomedical field." Certainly it is irrelevant what physicians may think on the subject. Nor do I see why it makes a difference to research scientists in most fields. The prof is simply imposing a substantively irrelevant religious test.

If the professor feels strongly enough about it, his proper course of action would be to write a straightforward recommendation and then express his concern in an explanatory postscript. This, of course, would make the professor look small, which is probably why he doesn't handle it this way.

The professor is wrong.

No he's not. How on Earth can you possibly expect to force someone to recommend someone? It is a private matter & he can refuse for any - or no - reason whatsoever.
