Question

which of the following is the best definition of biogeographic isolation?
the separation of members of a species through geographical or biological forces
the separation of members of different species through geographical forces
the separation of populations of different species through time
the separation of members of a species through anatomical forces

Explanation:

Biogeographic isolation refers to the separation of members of the same species. This separation can occur due to geographical (like mountains, rivers) or biological (like changes in mating times) forces. The second option is incorrect as it mentions different species. The third option is wrong as it refers to different species and time. The fourth option is incorrect as it mentions anatomical forces which is not related to biogeographic isolation.

Answer:

the separation of members of a species through geographical or biological forces
