EVO KC-3: Speciation

When two species trigger evolutionary changes in each other?

• coevolution

• microevolution

• macroevolution

• speciation

Evolutionary change within a species or small group of organisms, especially over a short period.

• overharvesting

• macroevolution

• adaptive radiation

• microevolution

Movement of alleles from one population to another

• speciation

• gene flow

• extinction

• lineage

Evolution from a common ancestor of many species adapted to diverse environments.

• overharvesting

• reproductive isolation

• adaptive radiation

• microevolution

A term that typically describes a species that no longer has any known living individuals.

• mechanical isolation

• microevolution

• speciation

• extinction

Adaptive radiation increases the biodiversity after a mass extinction.

• true

• false

Occurs when natural selection favors one of the extreme variations of a trait

• behavioral isolation

• directional selection

• mechanical isolation

• geographic isolation

The theory that species evolve during short periods of rapid change.

• punctuated equilbrium

• reproductive isolation

• rate of speciation

• directional selection

Form of reproductive isolation in which two populations have differences in courtship rituals or other behavior that prevent them from interbreeding.

• behavioral isolation

• stabilizing selection

• mechanical isolation

• disruptive selection

Form of natural selection in which a single curve splits into two; occurs when individuals at the upper and lower ends of a distribution curve have higher fitness than individuals near the middle

• directional selection

• disruption selection

• behavioral isolation

• stabilizing selection
