单词 Sivapithecus
释义
Sivapithecus

Biology
  • A genus of extinct primates that lived about 12–8 million years ago. Fossil remains of sivapithecines have been found in India and Pakistan, the Near East, and East Africa. Early discoveries of jaw fragments suggested that they chewed from side to side and had fairly short muzzles, both of which are humanoid features. However, subsequent finds, including a complete jaw, were not hominoid, and sivapithecines are now regarded as ancestral to the Asian great apes (e.g. orang-utans), not the hominins. See also dryopithecus; australopithecus.


Geology and Earth Sciences
  • Genus of early hominoid Primates, which probably includes the so-called Ramapithecus. They are known from E. Africa, south-eastern Europe, Turkey, Arabia, Pakistan, northern India, and southern China, from the Middle and Late Miocene 15–8 Ma ago. The genus may include ancestors of great apes and humans, but certainly early relatives of the orang-utan have been identified among species of the genus. Although there are similarities between the teeth of Sivapithecus and those of humans, these are probably misleading, and Sivapithecus is now regarded as an ape that was ancestral either to the orang-utan alone, or to all living great apes and humans.
