Evolution and Structure Quiz

Evolution

• Structures inherited from ancestors, but have lost much or all of their original function due to different selection pressures.

• The process by which organisms with variations most suited to their local environment survive and leave more offspring.

• Change in allele frequency in a species over a long period of time.

Homologous Structure

• Structures that have common structure, but may not share common function.

• The process by which organisms with variations most suited to their local environment survive and leave more offspring.

• Evolution happens in short bursts of rapid change.

Analogous Structure

• Structures that have a common function, not common structure.

• Change in allele frequency in a species over a long period of time.

• Any heritable characteristic that increases an organism's ability to survive and reproduce in its environment.

Vestigial Structure

• Evolution happens in short bursts of rapid change.

• Structures inherited from ancestors, but have lost much or all of their original function due to different selection pressures.

• Each new species evolves continuously over long spans of time.
