Evolutionary distances of species. a. Evolutionary distances of 17 species calculated with AGO proteins. The X-axis shows the different species, and the Y-axis shows the evolutionary distances of two adjacent species; b. Evolutionary distances of 15 species calculated with AGO proteins and miRNA families. The red line indicates the distances calculated with the miRNA family information, and the black line indicates the distances calculated with AGO proteins
