Michael J. Behe, a central figure in the Intelligent Design movement, is professor of biochemistry at Lehigh University in Pennsylvania and a senior fellow of the Discovery Institute's Center for Science and Culture. He is the author of Darwin's Black Box: The Biochemical Challenge to Evolution and most recently The Edge of Evolution: Searching for the Limits of Darwinism. In this conversation with D.J. Grothe, Behe discusses his prominent role in the ID movement, and how he first got involved. He explores the differences between creationism and Intelligent Design theory, and details some of his experiences as a key witness for the defense in the Dover, Pennsylvania Intelligent Design trial. He also explains the thesis of his new book, and talks about what he considers the biases of mainstream science.
