Which best describes biogeographic isolation?

a. It always lead to the formation of new species

b. It cannot lead to evolution

c. It is a mechanism for evolution

d. It occurs only through geographic forces

Answer:-  C. This is a mechanism for evolution

The correct answer is ‘it is a mechanism for evolution.’ Biogeographic isolation is a process that can lead to the formation of new species. It occurs when a population of organisms is separated from the rest of the species by a physical barrier, such as a mountain range or an ocean. This separation prevents the two populations from interbreeding, and over time they may evolve into different species.

Biogeographic isolation is not the only mechanism for evolution. Other mechanisms include natural selection, genetic drift, and mutation. However, biogeographic isolation is an important mechanism for evolution, and it has played a role in the formation of many new species.
