Diameter of the gene neighborhood networks. The relationship between backbone stability and diameter for simulations (lines, colors as in Figure 3) and intra-species comparisons (dots). We find that most genomes evolve by moving genes at large distance from the original position; Buchnera has a markedly different behavior, with data points mainly located in between the evolutionary model with only deletions (magenta) and local rearrangements (green).
