Irreducible complexity


Have you heard of an “irreducible complexity?” It consists of any complex system that cannot be simplified without being destroyed. DNA is a good example. If a DNA molecule were stretched out, it would be roughly four feet long, consisting of specific proteins and amino acids arranged in a precise order. Every living thing has its own DNA sequence. The complete sequence must exist entirely at once. It cannot develop gradually, although once it exists it may be altered artificially by splicing new genes into an existing system.

The complexity of DNA and the need for a completed molecular sequence for each creature brings into question the concept of evolution as an explanation for the origin of life. Skeletal remains of new creatures formed during the “Cambrian Explosion” do not indicate gradualism of formation. Instead, many new forms of life appeared on earth all at once.

Therefore, it takes more faith to believe in evolution as an explanation for the source of life than to believe in a creator. My thanks to Lee Strobel for introducing the “irreducible complexity” concept.
