Evolution or Creation?
Irreducible Complexity
Lehigh University professor of biochemistry Michael Behe's 1993 book Darwin's Black Box had an enormous impact on the scientific world. It shows that at the molecular level (the proteins and enzymes) the picture of every organism is one of irreducible complexity. They are more complex than a computer or a space ship and filled with intricate parts which all have to work together.[39]
For example, complex functions like vision and digestion are performed by intricate biochemical molecular machines. If one part were to evolve in isolation, the entire system of interacting parts would stop functioning; and since, according to Darwinism, natural selection preserves the forms that function better than their rivals, the nonfunctioning system would be eliminated by natural selection - like the fish with lungs. Therefore, there is no possible Darwinian explanation of how irreducibly complex structures and systems came into existence.[15,57]
Living things cannot simply change piecemeal - a new organ here, a new limb there. An organism is an integrated system with many interdependent components, and any isolated change in the system is more likely to be harmful than helpful.[15]
Even Darwin himself understood the problem and admitted that it could falsify his theory. "If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications," he wrote, "my theory would absolutely break down." Today we can say with confidence that his theory has broken down, for we now know that creation is full of examples of complex organs that could not possibly have been formed by numerous, slight modifications - life is just too complex to support the theory of evolution.[15,57]
