Bio Evolution quiz

Process which can occur over a few generations, in which a population's allele frequencies change in any way.

Occurs when natural selection selects for indivuals with one extreme phenotype.

Occurs when natural selection selects for individuals with the intermediate phenotype.

Occurs when natural selection selects for individuals with both extreme phenotypes.

The genetic variation of the recieving population.

Changes in allele frequencies that are due to change.

A genetic drift that occurs after an event greatly reduces the size of population, and only a few organisms of a population survive.

A genetic drift that occurs after a small number of individuals colonize a new area.

When certain traits increase mating success.

Species from two populations can no longer mate successfully, for any reason.

The rise of two or more species from one existing species

Species from two populations are seperated due to differences in courtship or mating rituals.

Involves physical barriers that divide of population into or more groups.

Exists when timing prevents reproduction between populations.

Process in which unrelated species evolve similar traits while adapting to similar environments.

Process in which closely related species become more and more different as they adapt to different environments.

Process in which two species evolve in response to changes in each other, over many generations.

The elimination of a species from Earth

Bursts of evolutionary activity are followed by long periods of stability.

The rapid evolution of many diverse species from ancestral species.
