Ayala’s idea of net progress defines science best because it fluctuations of values of change can not be found with this type of progress. Net progress requires that later members of the sequence be better, on the average, than earlier members of the sequence (2003). This relates to science and evolution because it is obviously going to have flaws. For example, progress can’t rely on there being no fluctuations in the evolution of an organism because there is evidence that variation exists. Ayala further explains, “Progress requires a gradual improvement in the members of the sequence, but the rate of improvement may decrease with time” (Stanley, 2003, p.540). I think that this relates to science because it defines it as gradual improvement
