Michael Behe has upset the comfort of the Darwinists by highlighting a design attribute that he terms "irreducible complexity." Consider, as an example, the familiar household mousetrap in figure 2.
This simple device consists of five essential parts: (1) a platform which holds (2) a hammer driven by (3) a spring when restrained by (4) a holding bar until released by (5) a catch. This basic design has defied attempts to simplify it further, or to reduce its complexity. The significant feature is that with only four of the five parts one cannot catch 4/5ths as many mice! Its function depends on each of its essential elements, each of which involve substantial precision in their specification. "Natural selection" cannot operate until there is something to select from.
Behe then presents an example of "irreducible complexity" from nature by reviewing the tiny motor that powers the flagellum, which propels a bacterium through the water:
Figure 3: This tiny mechanism, positioned to penetrate the bacterium's protective outer membrane, consists of over 40 parts - each of which are essential to its functioning. Figure 4 presents a functional equivalent: with any of its 40 parts missing, this mechanism would not be functional and would be a casualty in the processes of "natural selection" postulated by the Darwinists. The bacterium, dependent upon its locomotion, would be likewise.
So how did it come about? All the Darwinists can do is assert rather than explain.

The Miniature City
Darwinists love to postulate the "simple cell." With the advent of modern microbiology, we now know "there ain't any such thing." Even the simplest cell is complex beyond our imagining.
As Michael Denton has pointed out, "Although the tiniest bacterial cells are incredibly small, each is in effect a veritable microminiaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up of 100,000,000,000 atoms, far more complicated than any machine built by man and absolutely without parallel in the nonliving world."
The "simple cell" turns out to be a miniaturized city of unparalleled complexity and adaptive design, including automated assembly plants and processing units featuring robot machines (protein molecules with as many as 3,000 atoms each in three-dimensional configurations) manufacturing hundreds of thousands of specific types of products. The system design exploits artificial languages and decoding systems, memory banks for information storage, elegant control systems regulating the automated assembly of components, error correction techniques and proofreading devices for quality control.
All by chance? All without a Designer? (How do you define "absurd?")
When I was at the Ford Motor Company, one of our proudest assets was the famous River Rouge Plant in Dearborn. It was the largest totally integrated manufacturing facility in the world. With 97 miles of railroad within the plant, raw iron ore and limestone entered one end; the necessary steel, glass, and paint were manufactured within the facility. The entire cars (including the engines on automated lines) were fabricated within the plant, and new Mustangs came out the other end. Yet this entire complex pales in comparison to the elegant high order of design demonstrated in the simplest cell, which can also replicate itself in a matter of hours.
