Question

Differentiate Between Dryopithecus and Ramapithecus primates.

Answer 1

Hint: It has been established that in late Miocene epoch, Dryopithecus gave rise to Ramapithecus ('Rama' = The hero of Indian legend, Pithecus = Ape) which was on the direct line of human evolution.

Complete answer:

Dryopithecus	Ramapithecus
Dryopithecus is the genus of extinct ape that is representative of early members of the lineage that includes humans and other apes.	Ramapithecus, resembled more like man, then lesser apes.
They were present about 15 million years ago in Miocene epoch.	They were fossil primate dating from the Middle and Late Miocene epochs (about 16.6 million to 5.3 million years ago).
The Dryopithecus has been known by a variety of names based upon fragmentary material found over a widespread area including Europe, Africa, and Asia, it appears probable that only a single genus is represented.	They were present about 15 million years ago in the Siwalik Hills. The first Ramapithecus fossils (fragments of an upper jaw and some teeth) were discovered in 1932 in fossil deposits in the Siwālik Hills of northern India.
They resemble more like apes. Their Forelimbs were longer than hindlimbs.	They resembled more like man, then lesser apes. Their forelimbs were smaller than hind limbs.

Additional information: Dryopithecus were found as fossils in Miocene and Pliocene deposits (23 to 2.6 million years old) and apparently originated in Africa. Several distinct forms of Dryopithecus are known, including small, medium, and large, gorilla-sized animals. Their canine teeth are larger than those in humans but not as strongly developed as those in other living apes. The limbs were not excessively long. The skull lacked the well-developed crests and massive brow ridges found in modern apes.
Note:One of the most controversial, interesting, and persistent problems in paleoanthropology concerns the precise relationship of humans1 to our closest living relatives, the African apes.
