First off, they were not all Ph.D.s

Here was the quote from the article(I guess PHD level is somewhat different?)

Recently, 400 Ph.D.-level scientists, including a distinguished embryologist and member of the Russian Academy of Sciences, signed a statement questioning the creative power of the natural selection/mutation mechanism.

Secondly, the question they were asked and the one that appeared above their names were subtley, but specifically different.

What were they actually asked?

I would assume if they were Ph.D.s they would be identified as such, rather than as "Ph.D.-level." The latter could be doctoral candidates.
