We have studied the potential reasons for a conspicuous deviation of substitution rates in Dipteran ribosomal genes. Systematic pairwise relative-rate tests reveal that a significant increase in substitution rate is characteristic for Diptera, but not for the other insects analyzed. Estimation of...
