Moth species had experienced a change in gene frequencies within their populations, however with some decreasing also some thriving. The two moth species experienced low RS, given the changed environmental conditions, resulting in their extinction from England. …show more content…
Changes in the environment may be temporary, however, if the gene frequencies within a population also change, sometimes evolution has irreversible results. All of the natural selection
