What is Geographic Isolation

• Occurs when a population of a certain species are "ganged up on" by other species and surrounded in a valley or at the top of a hill and attacked.

• The separation of a population of organisms from the rest of it's species due to some physical barrier, such as a mountain range or ocean

• A fossil that has no other fossils of it's species near it

• Occurs when a population of organisms becomes the top of the food chain but in other habitats, other populations of that species are not the top of the food chain.
