A period of time in history marked by notable events.

• Genetic Drift

• Epoch

Reduced genetic diversity which results when a population is descended from a small number of colonizing ancestors.

• Genetic Drift

The evolution of whole taxonomic groups over long periods of time.

• Macroevolution

• Punctuated Equilibrium

• Interspecific

• Intraspecific

The hypothesis that evolutionary development is marked by isolated episodes of rapid speciation between long periods of little or no change.

• Macroevolution

• Punctuated Equilibrium

• Interspecific

• Intraspecific

A form of competition in which individuals of different species compete for the same resources in an ecosystem.

• Macroevolution

• Punctuated Equilibrium

• Interspecific
