<u>Answer</u>: Option A Pollution free environment increasing lichen growth.

<u>Explanation</u> :

  • The peppered moth has two varieties dark and light.
  • The difference in colour of these two moths is due to <em>industrial melanism</em> which resulted in the evolution of these moths.
  • Earlier, in a pollution free environment the moths were majorly light coloured as they could easily camouflage against the bark of the tree covered with lichen.
  • However, with industrialization the gases like suplhur dioxide killed the lichens covering the tree and hence, the moths evolved to be of darker color to easily camouflage against the now lichen free dark bark.

Thus, in a <em>pollution free environment </em>the lichen growth will <em>increase</em> and thus, the dark moths will find it difficult to camouflage and hence, <em>there population will decrease.</em>

Why do you think DNA evidence is so important in many court cases?
irinina [24]
