Darwin’s Black Box: The Biochemical Challenge to Evolution

work by Behe

Quick Summary

Darwin's Black Box: The Biochemical Challenge to Evolution by Michael Behe argues that certain biological systems are "irreducibly complex". This means they are composed of multiple interacting parts, and removing any single part causes the entire system to fail. Behe contends that such systems could not have evolved through gradual, step-by-step natural selection, as proposed by Charles Darwin. Instead, he suggests they must have been created by an intelligent designer.1234

Behe uses examples like the bacterial flagellum, blood clotting, and the immune system to support his argument. Critics, however, argue that these systems are not irreducibly complex and that simpler precursor systems can be found in nature, demonstrating that evolution can account for their development.14
