Ramapithecus

Ramapithecus is a genus of extinct apes. Fossil remains of animals now assigned to this genus, dated from 12.2 million years old in the Miocene, have been found since the 19th century in the Siwalik Hills in the Indian Subcontinent. Any one of the species in this genus may have been the ancestor to the modern orangutans.

Some early discoveries were given the separate names Ramapithecus (Rama's Ape) and Bramapithecus (Brahma's Ape), and were thought to be possible ancestors of humans. This view is no longer considered tenable.

The first incomplete specimens of Sivapithecus were found in northern India in the late 19th century.

Another find was made in Nepal on the bank of Tinau River, Butwal; a western part of the country in 1932. This find was named "Ramapithecus". The discoverer, G. Edward Lewis, claimed that it was distinct from Sivapithecus, as the jaw was more like a human's than any other fossil ape then known,a claim revived in the 1960s. At that time, it was believed that the ancestors of humans had diverged from other apes 14 million years ago. Biochemical studies upset this view, suggesting that there was an early split between orangutan ancestors and the common ancestors of chimpanzees, gorillas and humans.
