One of the important consequences of geographical isolation is:

Options

  1. Apreventing speciation
  2. Bspeciation through reproductive isolation
  3. Crandom creation of new species
  4. Dno change in the isolated fauna.

Correct answer

B. speciation through reproductive isolation

Step-by-step solution

Speciation is the evolutionary process for the formation of new species. The species diversity occurs when gene flow within the common pool is interrupted by an isolating mechanism. Related Theory The isolation can occur through geographical separation of population known as allopatric speciation. When a few individuals of a species within the same geographical area suddenly become reproductively isolated and form new species, it is known as sympatric speciation.
