Interaction sites: Subfigures (a) and (b) report, respectively for hsa-miR-29a-3p and hsa-let-7e-5p, the percentages of tags accounting for the conserved interaction sites on the left y-axis and the absolute reads counts on the right y-axis. Each interaction sites is coloured according to the legend reported in Fig. 8. The first 14 bars are relative to human samples, whereas the last 14 to the macaque ones. Each sample is labelled with a unique identifier in the format species_numsample-age: The character h and m identify respectively human or macaque samples, numsample ranges from 01 to 12 for both the species and the age is in the form of years. The bold line, that separates in two groups the analysed samples in both the species, is located at the transition age. The black trend curve reports on isomiR-SEA reads counts
