A Mightless Mite
The wing of a peppered moth has been magnified to focus on the microscopic mite invisible to the naked eye. In the late 1800s, the first white peppered moth was discovered in England. Darker morphs emerged only after the advent of the industrial era, as an adaptation to avoid standing out against trees coated with soot. Evolutionary biologists observed that the adaptive population fluctuations, began outnumbering the white moths, which are today barely seen.
