Reproductive Isolation

Reproductive isolation occurs when reproductive barriers prevent or strongly limit reproduction between populations. The result is that few or no genes are exchanged between the populations.

Metapopulations

A group of spatially separated populations of the same species which interact at some level.

Evolutionary History

The chronological sequence of biological changes in populations or organisms over time, leading to the diversity of species seen today.
