Why the Efficiency of Biological Organisms Cannot Be Explained by Evolution

by J Warner Wallace

Even atheistic scientists stipulate to the appearance of design in biological organisms. Richard Dawkins would be the first to agree: “Biology is the study of complicated things that give the appearance of having been designed for a purpose.” One example of the appearance of design in molecular organisms has become the icon of the Intelligent Design movement. Biochemist Michal Behe wrote about the bacterial flagellum twenty years ago in his famous book, Darwin’s Black Box. The flagellum bears a striking resemblance to the rotary motors created by intelligent designers. University of Utah Biology Professor David Blair describes the amazing similarities: “An ensemble of over forty different kinds of proteins makes up the typical bacterial flagellum. These proteins function in concert as a literal rotary motor. The bacterial flagellum’s components stand as direct analogs to the parts of a man-made motor, including a rotor, stator, drive shaft, bushing, universal joint, and propeller.”

In my latest book, God’s Crime Scene, I describe eight attributes of design and explain how the presence of these attribute is best explained by the activity of a designer. When these eight design characteristics are present in objects we observe in our world, we quickly infer a designer without reservation. As it turns out, the same attributes of design (dubious probability, echoes of familiarity, sophistication and intricacy, informational dependency, goal direction, natural inexplicability, efficiency/irreducible complexity, and decision/choice reflection) are present in bacterial flagella, making them prohibitively difficult to explain on the basis of chance mutations and the laws of physics or chemistry alone. Life at its simplest and most foundational level demonstrates a staggering level of efficient complexity.

The natural mechanisms of strict evolutionary processes can’t explain the flagellum for an important reason…
