Question

jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. which of the following would make the best project?
a video that shows lemur species that have different grooming behaviors.
a video that shows the island of madagascar with lemur populations separated from the mainland.
a video that shows lemurs with different feeding times living together.
a video that shows a lemur interacting with other animals in its habitat.

Explanation:

Geographic isolation occurs when a population is separated by a physical geographic barrier (like an ocean separating an island from a mainland) that prevents gene flow between groups. The correct option directly demonstrates this separation, while the others show behavioral differences or interactions not related to geographic separation.

Answer:

B. a video that shows the island of Madagascar with lemur populations separated from the mainland.
