When there is low gene flow When there is no selective pressure When there is a bottleneck
Predators create a selective pressure on a population. For example, birds that eat insects put a selective pressure on the insects to have better camouflage. Lions that run fast put a selective pressure on their prey to be able to run even faster.Its the same as a selective pressure created by the environment like adaptation to living in a cold environment. Those that can survive the cold the best live. The insects with the best camouflage survive as do the animals that can run the fastest.
The separation of a population, selective pressure, and/or time.

These plants and animals were subjected to artificial selection so that the traits humans wanted in the organisms were selected for and the organisms not having these traits were culled. This, with some modification, is a good analogue for natural selection and artificial selection shows how organisms can be shaped over time with the proper selective pressures. The selective pressure of humans in artificial selection and the selective pressure of the environment in natural selection.
