Question

Statement Populations of a species inhabiting different geographical areas are in a continuous process of adaptation to their surrounding environments and this leads to the evolution of new species. Reason Geographical barriers obstruct interbreeding of populations of a species leading to reproductive isolation and evolution of new species.

• B. Only Statement is true but not Reason
• C. Both Statement and Reason are true but Reason does not explain Statement
• D. Both Statement and Reason are true and Reason is correct explanation to Statement

Answer: (D)

Geographical isolation is the separation of two populations of the same species or breeding group by a physical barrier, such as mountain or body of water. It may ultimately lead to the populations becoming separate species by adaptive radiation, which leads to the evolution of new species.
