"I agree about your second point . Was this peppered moth not hailed as an `` example of evolution in action `` ? If so , this implies that it is proof of evolution ."
"No it does n't . Changes in allele frequencies in a population over time were observed . That is an example of evolution . Evolution is n't something that is `` proved. `` It is observed . Populations of organisms change over time due to the changing frequiencies of genetic make up . That is observed . Evolutionary biology tries to explain the reasons for the observed evolution . In the case of the peppered moth , natural selection due to the predation of birds has been proposed ."
