Figure 8.

The average number of mutations per generation for rapidly adapting, slow adapting, and non-adapting populations. Generation 0 represents the generation in which the change in fitness function was performed. Rapid mutating populations see a significantly higher number of mutations per generation initially after the switch in fitness function. Slowly adapting populations see an increase initially, as well, but it is much more modest. All the populations eventually reach similar number of generational mutations as they adapt to the new target.
