Fraction of phenotypes unique to the neighborhood of an evolving metabolic network G k (vertical axis) when compared to the neighborhood of a starting metabolic network G after k "mutations", i.e., reaction changes (horizontal axis). Each data point represents an average over 200 evolving metabolic networks of size N = 200 (20 random walks for 10 different sets of environmental demands with the same number S of required sulfur sources).
