The Edge of Evolution

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. In the book, 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.

The book has been received well by creationists and non-biologists, but scientists working in relevant fields of biology have been highly critical of Behe's methods, information and conclusions in the book.
