Gradualism is defined as -

• slow changes over time

• sudden changes followed by stasis (no change)

Punctuated Equilibrium is defined as -

• slow changes over time

• sudden changes followed by stasis (no change)

DNA evidence is also known as -

• Fossil Evidence

• Biogeographical Evidence

• Structural Evidence

• Molecular Evidence

Structures that are similar in different organisms are called -

• Vestigial

• Analogous

• Fossil

• Homologous

Vestigial structures provide evidence of evolutionary history. For example, ostriches may not fly, but they do have wings indicating that they -

• have an ancestor that used to fly

• like to have wings for show

• use their wings to float, not fly
