Darwin's Natural Selection Seriously Challenged by Modern Microbiology

The principle of natural selection is at the core of the evolutionary hypothesis.
Charles Darwin in his "The Origin of Species" wrote,

"I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection."

However the great advances in modern microbiology have revealed information about the cell that were not known during Charles Darwin's lifetime. For example, Dr. Ray Bohlin, a Ph.D in molecular biology, describes the process that takes place in a blood clot,

"This seemingly straightforward process involves over a dozen different proteins with names like thrombin, fibrinogen, Christmas, Stuart, and accelerin. Some of these proteins are involved in forming the clot. Others are responsible for regulating clot formation. Regulating proteins are needed because you only want clots forming at the site of a wound not in the middle of flowing arteries. Yet other proteins have the job of removing the clot once it is no longer needed. The body also needs to eliminate the clot when it has outlived its usefulness, but not before."

Dr. Bohlin describes this principle as that of Irreducible Complexity, and explains that Natural Selection could not possibly account for the complexity of the cell. He writes,

"Let me first address this concept of irreducible complexity. It's really a quite simple concept to grasp. Something is irreducibly complex if it's composed of several parts and each part is absolutely necessary for the structure to function. The implication is that such irreducibly complex structures . . .cannot be built by natural selection because in natural selection, each component must be useful to the organism as the molecular machine is built."

That is, as matter "evolves" according to Darwinian theory, the chemicals needed to form a cell are present in nature, but not yet functioning together to form a cell. Natural Selection would not find individual chemicals useful, and so it would discard them. It would continue discarding the individual chemicals, and the cell would never be built. The scientific community has largely been unable to come up with an evolutionary pathway to explain the development of irreducibly complex biochemical systems, much less the cell. It sure takes a lot of (blind) faith to believe in evolution.
