It’s in the nature of urban legends that they thrive, not in scholarly locations, but on discussion boards, unmoderated fora, and the like.
So go here, for instance, and scroll down to the bottom:
Mike Behe “made up the terms” for his book Darwin’s Black Box. Now, if it were common knowledge that “micro-” and “macroevolution” were coined in 1927 by a leading Russian geneticist, explicitly in the context of drawing a strong qualitative distinction between the processes, regular folks who take an interest in the question wouldn’t credit their etymology to the likes of Mike Behe.
So, no, my claim is true. I think very highly of Christy as a moderator and fair-minded person – she is one of the motivations I have for visiting here – but there’s a reason she said what she did in the OP.
