Histograms summarizing the node degree statistics of the optimized rabbit and yeast ribosomal protein networks. Networks were analyzed in Cytoscape [34]. Distributions of node degrees were plotted in Pareto-scaled histograms featuring the number of nodes on the left y-axis and the proportion of nodes on the right y-axis. Note that in both cases a heavy-tailed distribution peaking at a range of 2.5–4.5 degree characterizes more than 30% of the nodes in both networks. As in other figures and supplemental tables, the rabbit network (6GZ5) is identified by red font and the yeast network (6SNT) is identified by black font
