Question

Which is the most primitive ancestor of man?
A. Ramapithecus
B. Autralopithecus
C. Homo habilis
D. Homo neanderthalensis.

Answer 1

Hint: It is the genus of extinct Miocene ape known from fossils found in India and Pakistan and formerly thought to be a possible human ancestor.

Complete answer:
To answer this question, we have to know about the evolution of humans. Human evolution is a process by which human beings evolved on Earth from now-extinct primates. We humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.

Now, let us find the solution from the option.
>Ramapithecus is a genus of extinct primates that existed about 12 million years ago. Australopithecus is the extinct great apes from the Hominidae family and is close relatives of humans.
> Australopithecus existed about 2.5 million years ago. Homo habilis is also an extinct individual of the genus Homo that existed about 2.3 million years ago.
>Homo erectus is considered to be the direct ancestors of several human species and modern humans. Homo erectus lived about 1.5 - 2 million years ago.
Homo sapiens neanderthalensis is an extinct species or subspecies who lived in Eurasia until about 40,000 years ago is the closest relative of modern humans.

Thus, the correct answer is A, i.e. Ramapithecus.

Note:Australopithecus lived just after Ramapithecus. Homo Habilis exist just after the Australopithecus. Neanderthals exist after that and their fossils are found in various continents. The current one was Cro-Magnon who lived almost 30,000 years ago.
