A population that becomes divided (isolated) by a physical barrier, allowing each of the separated groups an independent evolutionary path.

Geographic isolation refers to a barrier, such as a body of water or a mountain range, that physically separates two populations of a species. This isolation can lead to genetic divergence and eventually speciation as the separated populations evolve independently.
Geographic isolation Low geneflow.
Geographic isolation is when a population is separated by a river/canyon or some impassable terrain. Habitat isolation is when members of a population live in a different type of habitat, say some live in the forest at the bottom of the mountain, while others live further up the mountain. These would then become different populations and evolve to perhaps form two different species.

Geographic isolation occurs when populations are separated by physical barriers like mountains or rivers, leading to reproductive isolation. Temporal isolation involves populations that breed at different times of the day, season, or year, preventing interbreeding. Behavioral isolation refers to differences in mating behaviors and signals that prevent different species or populations from interbreeding.
