Question

One of the important consequences of geographical isolation is :

• A. Random creation of new species
• B. No change in the isolated fauna
• C. Preventing speciation
• D. Speciation through reproductive isolation

Answer 1

The correct option is D Speciation through reproductive isolation

Geographic isolation is a term that refers to a population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species. And one of the important consequence of geographical isolation is speciation through reproductive isolation. For example, if some fruit fly larvae were washed up on an island, and speciation starts because populations were prevented from interbreeding by geographic isolation.
