Instruction frequencies. For each data set; Avida with overlapping reward structure, Avida with non-overlapping reward structure, Avida with no-task reward structure, and control data generated by computer simulation; the frequency of each of the 26 unique instructions in the four leaf taxa is plotted. The data was generated using 100 replicate experiments for each data set with 400 instructions per replicate giving a total of 40,000 instructions. Each replicate used an internal branch length of 60 and an external branch length of 600.
