Of Pandas and People: The Central Question of Biological Origins is a controversial 1989 (2nd edition 1993) school-level supplementary textbook written by Percival Davis and Dean H. Kenyon, edited by Charles Thaxton and published by the Texas-based Foundation for Thought and Ethics (FTE). The textbook endorses the pseudoscientific concept of intelligent design – the argument that life shows evidence of being designed by an intelligent agent which is not named specifically in the book, although proponents understand that it refers to the Christian God. The overview chapter was written by young Earth creationist Nancy Pearcey. They present various polemical arguments against the scientific theory of evolution. Before publication, early drafts used cognates of "creationist". After the Edwards v. Aguillard Supreme Court ruling that creationism is religion and not science, these were changed to refer to "intelligent design". The second edition published in 1993 included a contribution written by Michael Behe.
