Congruent evolution of mutational and environmental robustness. Computation of mutational and environmental robustness (Rm and Re) during a neutral evolution (acceptance of mutations that do not change the structure) of a MicA-like sncRNA (scatter plot in the inset). These two trajectories show a pattern of congruent evolution. One iteration corresponds to 100 mutations (order O(L)).
