It isn't.
It's a guest editorial written by, you guessed it, a functionary from the anti-Evo and misnamed "Discovery Institute" :
"Jonathan Witt is a senior fellow with Discovery Institute and co-author of "A Meaningful World: How the Arts and Science Reveal the Genius of Nature" (IVP 2006)."
But in as much as the anti-Evos were caught lying through their teeth under oath in the Dover Trial, it would be of little surprise that their apologists here on FR would resort to milder forms of deception, such as camouflaging the TRUE source of the posted article, by way of omission.
