About Michael Behe

Michael Behe is an American biochemist, researcher, and professor of biology at Lehigh University, known for his work on intelligent design and its application to biology, particularly in the field of irreducible complexity. Born on November 18, 1952, in Philadelphia, Pennsylvania, Behe was raised in a Catholic family. He earned his B.S. in Biology at Swarthmore College in 1974 and his Ph.D. in Biochemistry from the University of Pennsylvania in 1979. His research focus initially centered around enzyme kinetics, but he gained significant attention with his book "Darwin's Black Box: The Biochemical Challenge to Evolution" published in 1996. In this work, Behe introduced the concept of irreducible complexity, proposing that certain biological systems are so complex that they could not have evolved gradually and must have been designed all at once. This idea has been widely debated within the scientific community, with critics arguing that it does not hold up under scrutiny due to the existence of evidence for evolutionary steps in these systems. Despite this controversy, "Darwin's Black Box" became a best-seller and helped propel Behe to the forefront of discussions on intelligent design. In 2007, Behe published "The Edge of Evolution: The Search for the Limits of Darwinism," where he argued that certain genetic modifications may be impossible due to limits in evolutionary potential. This work also received criticism from the scientific community, with many arguing that it misrepresented the current understanding of genetics and evolution. Throughout his career, Behe has been a vocal proponent of intelligent design, speaking at various conferences and debates on the topic. He continues to research and write on these subjects, maintaining his position as a key figure in the ongoing debate between evolutionary biology and intelligent design.

Interpretations of Popular Quotes

"Darwin made it seem as if design was not a real alternative to evolution."

Michael Behe's quote suggests that Charles Darwin's theory of evolution by natural selection has been misconstrued to imply that the concept of design or intelligent design is not a viable alternative explanation for the origin and development of living organisms. However, Behe's statement does not necessarily mean that he endorses intelligent design as a valid scientific theory; rather, it highlights a potential misunderstanding about the scope of evolutionary theory and its relationship with the concept of design in biology.


"In science, if you can't explain what's going on, you have to entertain the possibility that maybe it isn't happening."

Michael Behe's quote emphasizes the importance of understanding and explanation in scientific methodology. When a phenomenon cannot be explained or understood through observation and experimentation, it raises the question whether the event is actually taking place as claimed. This quote underscores the fundamental role of evidence and critical thinking in science. By entertaining the possibility that an unexplained occurrence might not be happening, scientists remain dedicated to seeking the truth, pushing the boundaries of our knowledge, and ensuring that their findings are supported by reliable evidence.


"The cell is not just a bag of enzymes, but a complex information processing system."

This quote highlights that the cell is not merely a container for various enzymes or chemical reactions, but it's a sophisticated information-processing system. It implies that the cell, like other information-processing systems, uses genetic and biochemical code to regulate, coordinate, and maintain its functions efficiently, much like how computers use binary code for processing data. The quote suggests that understanding the cell requires appreciation not just of chemistry or physics, but also of the principles of information theory and computing.


"Irreducibly complex systems cannot be reached by small, successive, randomly determined changes."

Michael Behe's statement suggests that certain biological systems, which he calls "irreducibly complex," are so intricately designed that they cannot have evolved gradually from simpler precursors through random processes alone. Instead, the implication is that these complex structures must have been created all at once, a perspective often associated with intelligent design theories and a challenge to traditional evolutionary theory. However, it's important to note that this view remains controversial within the scientific community as it is difficult to test and many believe that evolution by natural selection can indeed account for the development of complex systems over time.


"The challenge to the evolutionary paradigm comes from the complexity we see in the world around us."

This quote by Michael Behe implies that the intricate, complex structures observed within biological systems pose a significant challenge to the prevailing theory of evolution. The 'complexity' he refers to encompasses the design-like features and the interconnectedness of different components within living organisms, which some argue cannot be explained solely by natural selection and mutation, but may require intelligent design or other mechanisms yet to be discovered. This statement highlights an ongoing debate in the scientific community regarding the explanatory power of evolutionary theory, particularly with respect to understanding the origins of life's complexity.


It was a shock to people of the nineteenth century when they discovered, from observations science had made, that many features of the biological world could be ascribed to the elegant principle of natural selection.

It is a shock to us in the twentieth century to discover, from observations science has made, that the fundamental mechanisms of life cannot be ascribed to natural selection, and therefore were designed. But we must deal with our shock as best we can and go on.

Although Darwin was able to persuade much of the world that a modern eye could be produced gradually from a much simpler structure, he did not even attempt to explain how the simple light sensitive spot that was his starting point actually worked.

In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred.

A man from a primitive culture who sees an automobile might guess that it was powered by the wind or by an antelope hidden under the car, but when he opens up the hood and sees the engine he immediately realizes that it was designed.

But sequence comparisons simply can't account for the development of complex biochemical systems any more than Darwin's comparison of simple and complex eyes told him how vision worked.

Biology has progressed tremendously due to the model that Darwin put forth. But the black boxes Darwin accepted are now being opened, and our view of the world is again being shaken.

This fact immediately suggested a singular event - that at some time in the distant past the universe began expanding from an extremely small size. To many people this inference was loaded with overtones of a supernatural event - the creation, the beginning of the universe.

Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.
