Figure 2
Evolutionary activity graph (above) and average population fitness (below) from a typical Evita run. The adaptive advantage of the genotypes causing the salient waves is indicated. The start of a significant wave generally corresponds to an increase in fitness. Note the cloud of neutral variants that cause one of the fitness jumps and act in the population like a single phenotype. These neutral variants are more fit than genotype 33aaf because they require one fewer instruction per execution of the copy loop. Note also that the significant wave due to genotype 32abl does not cause a significant fitness increase; it is nearly phenotypically equivalent to 32aaV because it executes only one fewer instruction per reproduction event than 32aaV.
