Question

Blue whales (Balaenoptera musculus) can weigh up to 170 tons and are the largest animals alive today. Their large size is thought to have protected them from large predators, such as Megalodon (Carcharocles megalodon), which would have preferred to eat smaller, less dangerous whales. What process best explains the evolution of the enormous blue whale body size
a. Natural selection.

b. Migration.

c. Genetic drift.

d. Non-random mating.

Answer 1

Answer:

Option c. Genetic Drift is the right answer

Explanation:

Due to random sampling of organisms results in the change of the frequency of an existing gene variant in a population is called as Genetic drift.

example: Baleen whales were moderately large. Baleen whales are the ancestors of the present-day blue whale. However, around 4.5 million year ago a massive evolution occurred in them which  was resulted in blue whale origination.
