Box plot showing marginal utility of signaling for genomes (fractional addition to fitness provided by messaging, see "Methods") sampled from peaks H0–H3 of the fitness distribution obtained from simulations at a high mutation rate (see Fig. 1b). Only peak H1 utilizes messaging as a facilitator for acquiring a higher fitness (significance measured using the two-tailed non-parametric Wilcoxon test ***p < 0.001)
