Grass carp-specific miRNA evolved at a faster pace. A Ka/Ks ratios for all coding regions of grass carp. B Comparison of evolutionary rates between common miRNAs and specific miRNAs. Kp, Kf, and K were calculated by pairwise comparison of the orthologous miRNAs between grass carp and zebrafish. Multiple comparisons of samples by means of LSD (least significant difference) were carried out using R. Statistical significance was set at P < 0.05. *p < 0.05 and **p < 0.01 indicated statistical significance
