Several people have written to me expressing their concern over the recent publication of this paper:
Evidence for Intelligent Design in Gastrointestinal Endocrinology: Identification of Novel Cholecystokinin/Gastrin-Like Peptides in the Nematode Caenorhabditis elegans.
Greeley GH Jr, Endocrinology. 2008 Jun;149(6):3184-6.
Oh, no! Have the creationists scored a coup and snuck propaganda into a legitimate science journal? Have no fear. This is a short review paper by an editor describing some work on cholecystokinin phylogeny. Some of you old-school physiology types may recall that a colloquial term for this class of hormones is “brain-gut peptides” — molecules that are expressed in both the gut and the central nervous system (and many other places). CCK is produced in the endocrine cells of the upper small intestine and in neurons in the brain, apparently prompting a weak joke linking intelligence and gastrointestinal hormones. It is not pro-ID at all. It even says, “the work of Janssen and
co-workers elegantly defends the hypothesis that the mammalian CCK/gastrin-CCK1R/2R signaling system is an ancient signaling system with counterparts throughout the evolutionary tree.”
Turn off the sirens and return to your homes. All is well. It’s just another false positive in the literature for Intelligent Design.
