An ingenious system for generating thousands of point mutations in yeast genes and measuring their effect on fitness shows convincingly that, for the chosen subset of representative non-essential genes, silent mutations have as much effect on fitness as missense mutations. In other words, silent mutations are not neutral, at least under these conditions. This result has important implications for evolutionary biology.
