• the process by which one population evolves into two or more different species

• a group of the same type of organism living in the same area

What does this diagram show?

• All three species share a common ancestor, but the African elephant and Sumatran tiger are more closely related to each other than they are to the Norway rat.

• All three species share a common ancestor, but the Sumatran tiger and Norway rat are more closely related to each other than they are to the African elephant.

• The Sumatran tiger, African elephant, and Norway rat are not related and come from separate lines of evolutionary history.

• All three species share a common ancestor and are equally related to each other.
