During the industrial revolution in England, the soot from the coal burning factories started dominating the environment. The trees were also darkened as a result and the light-bodies moths that were able to blend with the light-coloured lichens and tree barks were in danger due to their predation by the birds. This lead to the rapid decrease in the light-colored moths. As a result, the moths got adapted to the blackened trees with their transformation into dark-coloured moths which Increased rapidly. This was because the allele for the dark-bodied moths is dominant and the allele for the light-bodied moths is recessive. Since birds would find and eat the light-bodied moths, dark-coloured moths increased as a result of natural selection. Thus, these moths with a favorable adaptation to the change in the environment were selected and they reproduced new offspring.

In 1960’s, it spread to the community and eventually spread across the world.
Moreover, Staphylococcus<span> aureus infections <span>can
be treated with penicillin in the past but when it became resistant to penicillin, pharmaceutical companies discovered methicillin,
which is a derivative of penicillin. However, </span>S. aureus resistant was also develop with methicillin from late 1980’s
in the hospital and in the community from the start of year 2000.</span>
