When multiple transitional fossils are found in many rock layers, they provide evidence of

• seasonal variation in the diet of a species

• gradual changes of a species over time

• DNA functioning as the genetic material of organisms

• an unchanging environment

The diagram shows data on the evolution of horses.

The data in the diagram is evidence that

• a new species of horse suddenly appeared

• horses slowly developed over time

• horses have similar stages of rapid embryological development

• horses have a common ancestry with other hooved animals.
