Irreducible Complexity

Irreducible complexity already established by Michael J. Behe will not be negated by future biochemical discoveries; it will only be reinforced. The bacterial flagellum, intracellular transport, cilium, human knee joint, immune system, AMP synthesis, vision, DNA replication, electron transport, telomere synthesis, photosynthesis, and transcription regulation are irreducibly complex. Irreducible complexity indicates intelligent design. Design implies a Designer. Behe and William A. Dembski have demonstrated that design is detectable. Behe says that "irreducibly complex biological systems defy a Darwinian explanation" because "evolution can't produce an irreducibly complex biological machine suddenly, all at once, because it's much too complicated. The odds against it would be prohibitive. And you can't produce it directly by numerous, successive, slight modifications of a precursor system, because any precursor system would be missing a part and consequently couldn't function. There would be no reason for it to exist. And natural selection chooses systems that already working. ... the more complex the interacting system, the far less likely an indirect route can account for it. And as we discover more and more of these irreducibly complex biological systems, we can be more and more confident that we've met Darwin's criterion of failure."

[1] The Case For A Creator (Lee Strobel, 198). In On The Origin of Species, Charles Darwin stated his criterion of failure thusly: "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."
