Scientists observe anatomical features that have similar structures but serve different functions in different organisms, such as the forearms of the organisms in the diagram. What does the similarity in forearm structure of these four organisms suggest?

• There is no evolutionary relationship between the four organisms. 

• Because the whale forearm is adapted to life under water, it does not share a common ancestor with the other three organisms. 

• The whale, human and dog have common ancestor, but they do not share a common ancestor with the bird. 

• The four organisms have a common ancestor.

Geologists discovered fossil evidence of mesohippus, an ancestor of the modern horse. Mesohippus lived in North America about 40 million years ago. Mesohippus was about two feet tall, ran on hooves with three toes, and had large, grinding teeth.

What statement is BEST supported by the fossil evidence?

• Ancient horses were once carnivores.

• Horses migrated from South America into North America.

• Modern-day horses share a common ancestor with all mammals.
