a Box plots showing genomic heterogeneity within populations belonging to H0–H3 peaks of the fitness distribution obtained from simulations at a high mutation rate (see Fig. 2b). b Change in population heterogeneity when populations dominated by H1 are transplanted with H3 copy-loop and evolved for 5000 updates (Populations evolved under size 500 and 1000 k resource availability). c Change in population heterogeneity when populations dominated by H3 are transplanted with H1 copy-loop and evolved for 5000 updates. Population heterogeneity is measured by calculating the sum of per-site genomic entropies (see “Methods”, significance calculated using the non-parametric Wilcoxon test; **p < 0.01, ***p < 0.001). “WT” denotes heterogeneity of the recipient population without copy-loop replacement
