Option A) It always leads to the formation of new species Option
B) It cannot lead to evolution Option
C) It is a mechanism for evolution Option
D) It occurs only through geographic forces
Answer: The best description of biogeographic isolation is: Option C) It is a mechanism for evolution.
Explanation:-
Biogeographic isolation refers to the physical separation of populations of organisms, often caused by geographic barriers such as mountains, oceans, or rivers. This isolation can lead to genetic divergence as the separated populations adapt to different environmental conditions and experience different selection pressures. Over time, these genetic differences may accumulate and lead to the formation of new species. Therefore, biogeographic isolation is a mechanism for evolution.
