On one side, the Discovery Institute, a Seattle-based think tank, is leading a campaign to change the language of biology books to include weaknesses in the theory of evolution.
"There is considerable debate in scientific circles about the mechanism of evolution, namely how it happened," said William Dembski, a Baylor research professor who agrees with the Discovery Institute.
"All the textbooks under consideration grossly exaggerate the evidence for neo-Darwinian evolution, pretending that its mechanism of natural selection acting on random genetic change is a slam dunk. Not so."
