The word "fail" usually implies that something went wrong. To fail a school exam decreases the chances of passing the course, and failing a physical exam portends poor health. But when scientists studied yeast and bacteria that "fail to optimize" the production of certain proteins, they discovered that's actually a very good thing.

Researchers just announced the systematic laboratory induced mutation of successive amino acids over the entire sequence of a simple bacterial protein.¹ The results showed how even the simplest of life's proteins have irreducibly complex chemical structures. The research also showed how random evolutionary processes that are ascribed to mutations are unable to propel evolution.

God appears to have left His unmistakable signature throughout His creation, even on the smallest parts.

The eye is an ingeniously designed biological mechanism. In 1802, William Paley used eyes as a clear illustration of what he called "contrivances," i.e., "well-designed machines." Before Charles Darwin's publications, many naturalists used Paley's textbook, Natural Theology.
