Context paragraphs:
The Edge of Evolution: The Edge of Evolution: The Search for the Limits of Darwinism is an intelligent design book by Discovery Institute fellow Michael Behe, published by the Free Press in 2007.  Behe argues that while evolution can produce changes within species, there is a limit to the ability of evolution to generate diversity, and this limit (the "edge of evolution") is somewhere between species and orders.  On this basis, he says that known evolutionary mechanisms cannot be responsible for all the observed diversification from the last universal ancestor and the intervention of an intelligent designer can adequately account for much of the diversity of life.  It is Behe's second intelligent design book, his first being "Darwin's Black Box".

Kitzmiller v. Dover Area School District: Tammy Kitzmiller, et al. v. Dover Area School District, et al. (400 F. Supp.  2d 707, Docket No. 4cv2688) was the first direct challenge brought in the United States federal courts testing a public school district policy that required the teaching of intelligent design.  In October 2004, the Dover Area School District of York County, Pennsylvania, changed its biology teaching curriculum to require that intelligent design be presented as an alternative to evolution theory, and that "Of Pandas and People", a textbook advocating intelligent design, was to be used as a reference book.  The prominence of this textbook during the trial was such that the case is sometimes referred to as the Dover Panda Trial, a name which recalls the popular name of the Scopes Monkey Trial in Tennessee, 80 years earlier.  The plaintiffs successfully argued that intelligent design is a form of creationism, and that the school board policy violated the Establishment Clause of the First Amendment to the United States Constitution.  The judge's decision sparked considerable response from both supporters and critics.
