• Analogous

• Homologous

• Vestigial

Natural selection leads to

• populations becoming better adapted over many generations.

• individuals changing to adapt to environment.

• almost nothing going extinct.

Mutations, gene flow and choosing a "fit" mate can all lead to

• new variations.

• nothing; they make no difference.

• extinction in all cases.
