A new link in the evolutionary history of man and ape has been discovered by the Yale North India Expedition. Investigation of fossil jaw bones and teeth brought back by the expedition reveals the existence of man-like apes nearer to the main trunk of man's evolution than any living or extinct great apes previously known. The family to which these man-like apes belong could develop in several directions, some becoming more like the great apes, others approaching man.
Three entirely new genera are included among the five fossil jaws found in the badlands region of Potwar, India. Once has been named Ramapithecus, after Rama, the hero of a Sanskrit epic. Another is named Sugrivapithecus, after Sugriva, king of the monkeys in the same saga. The jaw of Sugrivapithecus indicates that the animal had a well- developed chin, a sign of high evolution, said the discoverer of the remains, G. Edward Lewis, the expedition's paleontologist. The chin is more like that of a primitive man that that of any living great ape. Many features of the teeth show parallels with human anatomy.
FROM WIKI PEDIA HOWEVER Sivapithecus is a genus of extinct primates. Fossil remains of animals now assigned to this genus, dated from 12.5 million to 8.5 million years old in the Miocene, have been found since the 19th century in the Siwalik Hills in what is now India and Pakistan. Any one of the species in this genus may have been the ancestor to the modern orangutans (AND EVEN US HUMANS)
