Which of the following is an example of gradualism?

• Massive tsunami

• Gradual evolution of peppered moths

• Meteor impact

• Sudden volcanic eruption

What is punctuated equilibrium?

• Slow, constant changes

• Gradual elimination of species

• Formation of new species

What is the main difference between gradualism and punctuated equilibrium?

• Gradualism involves rapid changes, punctuated equilibrium involves slow changes

• Gradualism involves slow changes, punctuated equilibrium involves bursts of change

• Both involve rapid changes

• Both involve slow changes
