Larger Size But Not Higher Fitness in Fit Runs Compared with Unfit Runs

Fitness		Size
1–100	101–200	1–100	101–200
=(P> 0.1)	=(P> 0.1)	+(P < 0.05)	+(P < 0.05)

Note.—Equal signs denote a lack of significant difference in the fitness during early evolution of runs in the fit set compared with unfit runs. Two cohorts are defined, of generations 1–100 and 101–200, respectively. Plus signs indicate that in early evolution, runs in the fit set have significantly larger genomes compared with unfit runs (Mann–Whitney U test).
