A small group of birds leaves the main population and starts a new population on a nearby island.

A flood suddenly kills most members of a population, leaving only a few survivors.

Two populations become separated by a mountain range and can no longer interbreed.

A population adapts to a new food source over time.

It occurs when populations are separated by physical barriers.

It happens when populations migrate to different regions.

It occurs within the same geographic area, without physical separation.

It always involves natural disasters.
