- If mutation acquisition was a random process and present before the presence of any selection pressure, then there would be high variation among survivability of bacterial plates. If not, the variance would be low since acquired mutation hypothesis would state that any organism could mutate to deter a stressor. The variance was extremely high in the experiment
