Evolution: The complete change of a species over time according to environmental factors.
|
Gene pool: A variety of traits that a whole species possesses.
|
Adaptation: A small change to a species according to their environment.
|
Speciation: Process of a population of a species evolving separate to the rest of the population.
|
Mutation: A random occurrence that leads to an extremely rare special trait.
|
Natural selection: When part of the population in a species survives and reproduces due to superior traits
|
Non random mating: When an organism chooses its mate due to preferences.
|
Shrinking population: When a population is so small there will be no genetic variation even if it grows.
|
Gene flow: When two populations of the same species reproduce.
|
Artificial selection: When humans decide which traits are good and breed with those traits.
|
Biodiversity: A variety of species in an environment
|
Extinction: No members of a species are left alive.
