  1. The lower half of the table shows the rates of evolution in nonsynonymous sites, and the upper half shows the rates of evolution in synonymous sites. Most of the synonymous evolution rates were at the saturation levels. However, in each case, the estimated nonsynonymous substitution rate was significantly lower than the corresponding synonymous rate, which is indicative of purifying selection at the amino acid sequence level.
