The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light colouration, which effectively camouflaged them against the light-coloured trees and lichens upon which they rested. However, due to widespread pollution during the Industrial Revolution in England, many of the lichens died out, and the trees which peppered moths rested on became blackened by soot, causing most of the light- coloured moths to die off due to predation. At the same time, the dark-coloured moths flourished because of their ability to hide on the darkened trees. Since then, with improved environmental standards, light-colored peppered moths have again become common, but the dramatic change in the peppered moth's population has remained a subject of much interest and study Which type of selection is illustrated by the peppered moth's during the Industrial Revolution?

Technology can bring both good and bad things. pesticides can make crops more resistant to insects (good) but can harm humans if they are used improperly (bad). give examples of both the good and bad
