Peppered moth

The Peppered Moth (Biston betularia) is a temperate species of night-flying moth. Peppered moth evolution is an example of population genetics and natural selection. The caterpillars of the peppered moth not only mimic the form but also the colour of a twig. Recent research indicates that the...

Peppered Moth (Biston betularia). A favourite of genetic studies, this species shows well the phenomenon of industrial melanism, where all-dark individuals became the dominant form in certain parts of northern England. Nowadays, the melanic form f. carbonaria is declining again in these areas. The flight period is from May to August, and the species is common throughout most of Britain though more locally distributed in Scotland. The larvae feed on a range of trees and plants, and can be…

On the plus side, Darwin bots can get away with bad science, dishonesty, and outright fraud for decades. However, the down side is that the ...
