If monkeys and foxes belong to the same class, they must also belong to the same: It is a hypothesis about the relationships among different group. The bottom of the v is how recently two species shared an ancestor. The larger the v the less recent the two species shared an ancestor. P hylog eny evolutionary history of a group.
