Question

Which is the best example of organisms that have been naturally selected? A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England. B. Light-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England. C. Both light-colored and dark-colored peppered moths on light-colored tree bark before the Industrial Revolution in England. D. Neither dark-colored nor light-colored peppered moths on light-colored tree bark before the Industrial Revolution in England.

Answer 1

The answer is A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England.

Answer 2

Answer: A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England.

Step-by-step explanation:

Natural selection is a process of differential survival and reproduction. It suggests that the organisms which have better traits are likely to survive in changing or adverse environmental conditions.

Among the options given, A. Dark-colored peppered moths on soot-covered tree bark during the Industrial Revolution in England. is the correct option. This is because of the fact that the during industrial revolution the emission of soot from the factories will mask the original light color of the tree bark. The dark colored peppered moths when lying on the bark of the tree will get an advantage of survival due to the similarity in the background. Hence, this will help the peppered moths in camouflaging and remaining undetected from the predators. Hence, it can be said that the dark color is the phenotypic trait which helps in survival of the dark colored peppered moths. Therefore, it is the example of natural selection.
