Michael Behe

American molecular biologist

Quick Summary

Michael Behe is an American molecular biologist and a leading scientific proponent of intelligent design (ID). ID is an argument that living organisms were created by an intelligent designer, posited as a refutation of Charles Darwin's theory of evolution.1

Behe's central concept is "irreducible complexity," which suggests that some biological systems are too complex to have evolved gradually through natural selection. He argues that removing any part of such a system would cause it to cease functioning, implying it must have been created whole. Examples he has cited include the bacterial flagellum, blood clotting, and the immune system. Critics argue that these systems can evolve through simpler precursor stages and that imperfections in nature contradict the idea of a perfect designer.12
