Simulated data for the change in survival rates over time. As the generations increase from very early to late, we expect that the survival of the irradiated flies will increase and look more like the curve for wild-type flies. Observation of a trend towards statistical insignificance compared to the initial mutant fly would strongly indicate that the population was evolving (the curve is shifting to the right). The determination that the population has evolved to be like wild-type will be at the point in which there is no statistical difference (p > 0.05) between the wild-type and mutant flies as illustrated as Ready to Validate.
