We'd like to begin by transporting you back to nineteenth-century England. The Industrial Revolution is taking hold, and the factories in the country's industrial heartlands are burning coal and pumping out black smoke. The residue from this smoke coats everything from buildings to trees.

Enter the peppered moth. In the 1800s, naturalists observed that peppered moths had evolved to fit in with this changed environment. The peppered moth is often found on the trunk of the silver birch tree and, therefore, its natural colouration is pale with darker spots, to match the colour of the tree's bark and camouflage it from predators. In highly industrialised areas of England, however, these moths were becoming darker in colour.

The pale-coloured moths stood out too much on the now-blackened bark of the trees and were therefore much easier for predators to spot. As a result, the pale moths were being eaten leaving the darker-coloured moths to survive and breed. Meanwhile, in regions where there was considerably less industrialisation the peppered moths remained pale in colour. They had no need to change their camouflage because their trees were not being darkened by soot.
