Michael J. Behe ( BEE-hee; born January 18, 1952) is an American biochemist, author, and advocate of the pseudoscientific principle of intelligent design (ID). He serves as professor of biochemistry at Lehigh University in Pennsylvania and as a senior fellow of the Discovery Institute's Center for Science and Culture. Behe is best known as an advocate for the validity of the argument for irreducible complexity (IC), which claims that some biochemical structures are too complex to be explained by known evolutionary mechanisms and are therefore probably the result of intelligent design. Behe has testified in several court cases related to intelligent design, including the court case Kitzmiller v. Dover Area School District that resulted in a ruling that intelligent design was not science and was religious in nature.Behe's claims about the irreducible complexity of essential cellular structures have been rejected by the vast majority of the scientific community, and his own biology department at Lehigh University published an official statement opposing Behe's views and intelligent design.
