Michael Behe

Behe also promotes Intelligent Design (ID) in his 2019 book, Darwin devolves whose central premise is that the combination of random mutation and natural selection, apart from being incapable of generating novelty, is mainly a degradative force. Like his previous books, Darwin devolves received negative reviews from the scientific community, including a scathing review in Science by Nathan H. Lents, Richard Lenski, and S. Joshua Swamidass, a harsh critique by Jerry Coyne in the Washington Post, and a detailed scholarly rebuttal from his own colleagues at Lehigh University.

"Inferences to design do not require that we have a candidate for the role of designer. We can determine that a system was designed by examining the system itself, and we can hold the conviction of design much more strongly than a conviction about the identity of the designer." — Darwin's Black Box, pp. 195–196

"Evolution is a controversial topic, so it is necessary to address a few basic questions at the beginning of the book. Many people think that questioning Darwinian evolution must be equivalent to espousing creationism. As commonly understood, creationism involves belief in an earth formed only about ten thousand years ago, an interpretation of the Bible that is still very popular. For the record, I have no reason to doubt that the universe is the billions of years old that physicists say it is. Further, I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it. I greatly respect the work of my colleagues who study the development and behavior of organisms within an evolutionary framework, and I think that evolutionary biologists have contributed enormously to our understanding of the world. Although Darwin's mechanism – natural selection working on variation – might explain many things, however, I do not believe it explains molecular life. I also do not think it surprising that the new science of the very small might change the way we view the less small." Darwin's Black Box, pp 5–6.

"For example, both humans and chimps have a broken copy of a gene that in other mammals helps make Vitamin C. ... It's hard to imagine how there could be stronger evidence for common ancestry of chimps and humans. ... Despite some remaining puzzles, there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives." The Edge of Evolution, pp. 71–72

In 2007, Behe's book The Edge of Evolution was published arguing 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.

The book was reviewed, by prominent scientists in The New York Times, The New Republic, The Globe and Mail, Science, and Nature who were highly critical of the work noting that Behe appears to accept almost all of evolutionary theory, barring random mutation, which is replaced with guided mutation at the hand of an unnamed designer. The book earned Behe the Pigasus Award for the year 2007.

Behe has written op-ed features in the Boston Review, The American Spectator, and The New York Times. Behe, along with fellow Discovery Institute associates William A. Dembski and David Berlinski, tutored Ann Coulter on science and evolution for her book Godless: The Church of Liberalism (2006). Coulter devotes approximately one-third of the book to polemics on evolution, which she terms "Darwinism." In the book, Coulter thanks Behe, Dembski and Berlinski for their assistance.

Behe received $20,000 for testifying as an expert witness on behalf of the plaintiffs in Association of Christian Schools International v. Roman Stearns. The case was filed by Association of Christian Schools International, which argued that the University of California was being discriminatory by not recognizing science classes that use creationist books. The 2005 filing claimed that University of California's rejection of several of their courses was illegal "viewpoint discrimination and content regulation prohibited by the Free Speech Clause." In 2007, Behe's expert witness report claimed that the Christian textbooks, including William S. Pinkston, Jr.'s Biology for Christian Schools (1980; 2nd ed. 1994), are excellent works for high school students. He defended that view in a deposition. In August 2008, Judge S. James Otero rejected Behe's claims, saying that Behe "submitted a declaration concluding that the BJU [Bob Jones University Press] text mentions standard scientific content. ... However, Professor Behe 'did not consider how much detail or depth' the texts gave to this standard content." Otero ruled in favor of the University of California's decision to reject courses using these books.

In 2004, Behe published a paper with David Snoke, in the scientific journal Protein Science that uses a simple mathematical model to simulate the rate of evolution of proteins by point mutation, which he states supports irreducible complexity, based on the calculation of the probability of mutations required for evolution to succeed. However, the paper does not mention intelligent design nor irreducible complexity, which were removed, according to Behe, at the behest of the reviewers. Nevertheless, the Discovery Institute lists it as one of the "Peer-Reviewed & Peer-Edited Scientific Publications Supporting the Theory of Intelligent Design."

In reviewing a book by Robert T. Pennock, Behe took issue with the "intelligent design" group being associated with "creationism," saying readers would typically take that to mean biblical literalism and young Earth creationism (YEC). In 2001 Pennock responded that he had been careful to represent their views correctly, and that while several leaders of the intelligent design movement were young Earth creationists, others including Behe were "old-earthers" and "creationists in the core sense of the term, namely, that they reject the scientific, evolutionary account of the origin of species and want to replace it with a form of special creation."

Many of Behe's statements have been challenged by biologist Kenneth R. Miller in his book, Finding Darwin's God (1999). Behe has subsequently disputed Miller's points in an online essay.

"Coyne's conclusion that design is unfalsifiable, however, seems to be at odds with the arguments of other reviewers of my book. Clearly, Russell Doolittle (Doolittle 1997), Kenneth Miller (Miller 1999), and others have advanced scientific arguments aimed at falsifying ID. ...If the results with knock-out mice (Bugge et al. 1996) had been as Doolittle first thought, or if Barry Hall's work (Hall 1999) had indeed shown what Miller implied, then they correctly believed my claims about irreducible complexity would have suffered quite a blow. And since my claim for intelligent design requires that no unintelligent process be sufficient to produce such irreducibly complex systems, then the plausibility of ID would suffer enormously. …Now, one can't have it both ways. One can't say both that ID is unfalsifiable (or untestable) and that there is evidence against it. Either it is unfalsifiable and floats serenely beyond experimental reproach, or it can be criticized on the basis of our observations and is therefore testable. The fact that critical reviewers advance scientific arguments against ID (whether successfully or not) shows that intelligent design is indeed falsifiable."

In 1997, Russell Doolittle, on whose work Behe based much of the blood-clotting discussion in Darwin's Black Box, wrote a rebuttal to the statements about irreducible complexity of certain systems. In particular, Doolittle mentioned the issue of the blood clotting in his article, "A Delicate Balance." Later on, in 2003, Doolittle's lab published a paper in the peer-reviewed journal Proceedings of the National Academy of Sciences which demonstrates that the pufferfish lacks at least three out of 26 blood clotting factors, yet still has a workable blood clotting system. According to Doolittle, this defeats a key claim in Behe's book, that blood clotting is irreducibly complex.

In 1996, Behe published his ideas on irreducible complexity in his book Darwin's Black Box. Behe's refusal to identify the nature of any proposed intelligent designer frustrates scientists, who see it as a move to avoid any possibility of testing the positive claims of ID while allowing him and the intelligent design movement to distance themselves from some of the more overtly religiously motivated critics of evolution.

"In fact, my argument for intelligent design is open to direct experimental rebuttal. Here is a thought experiment that makes the point clear. In Darwin's Black Box (Behe 1996) I claimed that the bacterial flagellum was irreducibly complex and so required deliberate intelligent design. The flip side of this claim is that the flagellum can't be produced by natural selection acting on random mutation, or any other unintelligent process. To falsify such a claim, a scientist could go into the laboratory, place a bacterial species lacking a flagellum under some selective pressure (for mobility, say), grow it for ten thousand generations, and see if a flagellum--or any equally complex system--was produced. If that happened, my claims would be neatly disproven."

For the 1993 edition of Pandas, Behe wrote a chapter on blood clotting, presenting arguments which he later presented in very similar terms in a chapter in his 1996 book Darwin's Black Box. Behe later agreed that they were essentially the same when he defended intelligent design at the Dover trial.

The 1987 Edwards v. Aguillard U.S. Supreme Court decision barred the required teaching of creation science from public schools but allowed evolutionary theory on the grounds of scientific validity. After the decision, a later draft of the textbook Of Pandas and People (1989) systematically replaced each and every cognate of the word "creation" with the phrase "intelligent design" or similar ID terms. The books of lawyer Phillip E. Johnson on theistic realism dealt directly with criticism of evolutionary theory and its purported biased "materialist" science, and aimed to legitimize the teaching of creationism in schools. In March 1992, a conference at Southern Methodist University brought Behe together with other leading figures into what Johnson later called the "wedge strategy." In 1993, the "Johnson-Behe cadre of scholars" met at Pajaro Dunes, California, and Behe presented for the first time his idea of irreducibly complex molecular machinery. Following a summer 1995 conference, "The Death of Materialism and the Renewal of Culture," the group obtained funding through the Discovery Institute. In 1996, Behe became a senior fellow of the Discovery Institute's "Center for the Renewal of Science and Culture" (later renamed the Center for Science and Culture), an organization dedicated to promoting intelligent design.

Behe says he once fully accepted the scientific theory of evolution, but that after reading Evolution: A Theory in Crisis (1985), by Michael Denton, he came to question evolution. Later, Behe came to believe that there was evidence, at a biochemical level, that some biological systems were "irreducibly complex". He thought that these systems could not, even in principle, have evolved by natural selection. He believed that the only possible alternative explanation for such complex structures was that they were created by an "intelligent designer". The logic is very similar to the watchmaker analogy given by William Paley in 1802 as proof of a divine creator. This argument of irreducible complexity has been rejected as an argument from ignorance relying on the lack of knowledge of a natural explanation to make the assumption of an intelligent cause outside of science.

Behe grew up in Harrisburg, Pennsylvania, where he attended grade school at St. Margaret Mary School and later graduated from Bishop McDevitt High School. He graduated from Drexel University in 1974 with a Bachelor of Science in chemistry. He received his PhD in biochemistry at the University of Pennsylvania in 1978 for his dissertation research on sickle-cell disease. From 1978 to 1982, he did postdoctoral work on DNA structure at the National Institutes of Health. From 1982 to 1985, he was assistant professor of chemistry at Queens College in New York City, where he met his wife, Celeste. In 1985, he moved to Lehigh University and is currently a Professor of Biochemistry. Lehigh University exhibits a disclaimer on its website stating that the University does not endorse Behe's views on evolution:

Michael J. Behe (/ˈ b iː h iː / 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 where his views were cited in the ruling that intelligent design is not science and is religious in nature.
