Molecular Machines and how they discredit evolution
Today, nanotechnology researchers build molecular machines. However, God has already created molecular machines with propellers, rotors, bushings, and more. None of this was known during Darwin’s life. Read about the fascinating description of how the tail of a bacteria works.
According to writer Nancy Pearcey, “More than a hundred years ago, Darwin thought the living cell was extremely simple—nothing but a bubble of jelly (protoplasm)….We now know that the cell bristles with high-tech molecular machinery far more complex than anything devised by mere humans.“1 These machines display, what Dr Michael Behe has termed, “irreducible complexity,” which occurs in a system comprised of well-matched, interacting parts that all must be present to work, and if any part is removed, the system will fail. For example, a mousetrap is irreducibly complex; all pieces of the mousetrap must be simultaneously present to work. The only reason that all of the pieces are present and assembled is to produce a mousetrap. There is no purpose for just a few of the pieces to be assembled; they all must be present and assembled at once. Darwinian natural selection cannot produce irreducible complex systems because random mutations cannot progressively assemble all the pieces at once. Assembling intermediate sub-assemblies has no purpose; the only purpose is assembling the final product.2
Behe cites the tail (flagellum) to some bacteria as an example (shown in Figure 1). The tail contains elements of a tiny motorized machine with a propeller, universal joint, rotor, and bi-directional motor operating at 100,000 RPM. These are intricate interacting parts that could not be produced by [Darwinian] ‘numerous, successive, slight modifications.’3 In contrast, only intelligent design could produce such molecular machines.
