Random mutant proteins

This is so cool. Through mathematical analysis of certain experiments, scientists at Princeton have found that protein chains in many organisms act to correct any imbalance imposed on them through artificial mutations, and restored their chains to working order. In other words, the living proteins know what they are supposed to be, and that the random mutations (not artificial) really do make up evolutionary theory.

Spore, anyone?
