Which of the following is the best definition of biogeographic isolation?
Answer:
The best definition of biogeographic isolation is “the separation of populations of different species through time.” This phenomenon occurs when populations of different species become isolated from each other over time, leading to the development of distinct gene pools and ultimately contributing to speciation. Biogeographic isolation can be the result of various factors such as geological events, ecological changes, or migration patterns that lead to the separation of populations and the subsequent evolution of new species. Therefore, it is the separation of populations from different species over a period of time, leading to unique evolutionary trajectories and genetic divergence.
