The orangutans are also the only surviving species of the subfamily Ponginae, which also included several other species, such as the three extinct species of the genus Gigantopithecus, including the largest known primate Gigantopithecus blacki.The ancestors of the Ponginae subfamily split from the main ape line in Africa 16 to 19 million years ago (mya) and spread into Asia.
