Specialization Can Drive the Evolution of Modularity
Figure 2
Modularity increase is not transient when selecting for a second additional gene activity pattern.
Modularity in the best adapted networks reaches a plateau that is maintained for, at least, 10,000 generations when selected to attain gene activity patterns I and II. Such plateau is significantly higher than that of networks selected to attain only activity pattern I. The length of bars represents one standard error. The plot shows results for 100 evolving populations in each selection regime.
