Still No Answer After 3 Decades: Darwin’s Theory Dismantled

Darwin himself had admitted in The Origin of Species: “If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.” Behe took Darwin at his word, and asked the question: Do such systems exist? His answer was yes — at the molecular level. Behe’s examples included the bacterial flagellum, the blood-clotting cascade, and the immune system. All are systems where the removal of any one part leads to collapse of function. With these systems, Behe did something few biologists dared: he asked whether a step-by-step Darwinian pathway could actually be demonstrated. His challenge was simple: show a testable, detailed, evolutionary route that builds an irreducibly complex system through random mutation and natural selection.
