- punctuated equilibrium: evolution characterised by long periods of little or no change followed by short periods of rapid change
- natural selection: mechanism of evolution — organisms survive if they have characteristics that make them suited to the environment
- artificial selection: human-driven selective force, e.g. breeding of plants and animals to produce desirable traits
- inbreeding: mating of individuals that are closely related
- outbreeding: mating of individuals that are not closely related
- speciation: the formation of a new species
