Solution

The correct option is B

accumulation of variations over several generations


The correct option is B.

Explanation of the correct option:

  1. Darwin’s evolutionary theory of natural selection gave a more rational explanation of the formation of new species.
  2. As per natural selection, various species originated from a single species as a result of adaptation to the changing environment.
  3. Accumulation of variations due to mutations in the genetic material over several generations forms new species.
  4. Natural selection may operate differently in different geographic locations.
  5. Eventually, different groups of new species will be formed from the same parent population.

Final answer: According to the evolutionary theory, the formation of a new species is generally due to accumulation of variations over several generations.
