I don't know if that's ever happened: A JW writing a thesis, an article or even a book supporting the theory of evolution.
I know many JW don't have the needed qualifications for the above, but let's assume someone actually did that. I know there are a few JW
who are professors, doctors, and so forth (although a minority).
Would that be considered automatic DA, or do the elders have to form a JC for this matter?
