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

Speciation through reproductive isolation is one of the important consequences of geographical isolation.

Geographical isolation happens when a group of plants, animals or other living individuals are separated from mixing genes within the indiciduals in the same species. Geographical isolation may ultimately lead to the populations becoming separate species by adaptive radiation.
