"It is certain that the mathematics of blood, the numbers inherent in its complex structure, provide perhaps the best evidence for the existence of some kind of Creator.
Take something like the process of coagulation, which requires the participation of several hemostatic proteins. ... It is hard not to understate the irreducibly complex nature of this system. The ratio of the probability that such a system might come into being by pure chance to the probability that it might not come into being is so enormous that it is almost impossible to find a number large enough to express these odds."
The code words in this explanation that link it to ID are "complex structure", "irreducibly complex", "pure chance" and the linking of this biochemical process to "evidence for the existence of some kind of Creator."
Kerr based his information, though, oddly he did not cite his source despite numerous footnotes throughout the novel, on the work of ID proponents Michael Behe, a biochemist, and William Dembski, a mathematician.
If you want to read more about how scientists and others have thoroughly discredited Intelligent Design and its predecessors Creationism and Creation Science, go to the National Center for Science Education's Web site, a United States organization that promotes the teaching of science in public schools. Use the NCSE site search and look up "blood clotting" to find several examples that debunk the ID claims that blood clotting is evidence of a designer of biological life, that is, a God.
Why spoil good fiction with pseudoscience when there's all kinds of perfectly good science out there?
