We added the following statement to the end of Section 3.3: “The simulation results of the previous section for β > 0.5 are unlikely to be affected by the domain size, however, since the features in those simulations are on a much smaller scale than the domain size and are also more chaotic, as seen in the correlation length and the global alignment (Figure 5a,d).”
Qualitative comparisons are made to the fossil record and modern experiments.
