Do gorillas and baboons evolve from a common ancestor?

Baboons belong to a part of the primate family called "Old World Monkeys" and Chimpanzees belong to a part called "Hominidae" (or the Great Apes). Both Hominindae and Old World Monkeys share a common ancestor, but after that the families branch off and continue on separate evolutionary paths. Baboons and Chimpanzees are very distant relatives, and neither one evolved from the other.
