Phenotypic evolvability (A) Ep, (B) ξp, (C) accessibility Ap, and (D) adjacent robustness Bp as a function of phenotypic robustness Rp for each of the three dynamical regimes: ordered (z = 1), critical (z = 2), and chaotic (z = 3). Each data point represents one of 2500 RBC instances for each dynamical regime. The insets depict the corresponding averages, as a function of z. Lines are provided as a guide for the eye.
