Back

A broader scale of evolutionary changes seen over paleontological time.

Front

Back

The variety of alleles in a population.

Front

Front

Microevolution

Back

Small-scale evolutionary changes within a population, often observed over a short time frame.

Front

Natural selection

Back

The process by which individuals with favorable traits are more likely to survive and reproduce.

Front

Genetic drift

Back

Random changes in allele frequencies in a population, often having a more significant effect in small populations.

Front

Gene flow

Back

The transfer of alleles or genes from one population to another, increasing genetic diversity.

Front

Adaptive radiation

Back

The process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.
