Question

All of the following are ape-men stages in the origin of man except
A. Ramapithecus
B. Kenyapithecus
C. Dryopithecus
D. Australopitecus

Answer 1

Hint:-Evolution is defined as a progressive development of living beings from ancestors having
different structural and functional organization. In the modern-man evolution theory, there are
basically four stages: the ape stage, ape-men stage, primitive men stage, and the modern man stage.

Complete step-by-step solution:-In human evolution, there are four main stages in the origin of man, they are:
1) Prior to ape-men or the ape stage
2) The Ape-men
3) the prehistoric men and
4) the modern man.
-The ape stage includes Propliopithecus and Dryopithecus, Dryopithecus lived almost 15million years ago, they were the direct ancestors of modern-day apes. Dryopithecusafricanus is regarded as the common ancestor of man and apes.
-The Ape-men stage includes Ramapithecus, Kenyapithecus, and Australopithecus.Ramapithecusappeared on earth 14 million years ago the fossils of which were discovered by Edward Lewis from the Pliocene rocks of Shivalik Hills of India. Australopithecus is the first ape-man, it is the connecting-link between apes and man. Australopithecus africanus existed until about1.5 million years ago and gave rise to Homo habilis, about 2 million years ago.
-The Primitive men stage includes Homo habilis, Homo erectus, Homo neanderthalensis.Homo habilis is also known as skillful man or handy-man as it was the first toolmaker, it had a brain capacity of about 650-800cc. Homo erectus existed about 1.5 million years ago,had a brain capacity of 900cc;made elaborate tools of stones and bones, hunted big animals, and perhaps knew the use of fire. Homo sapiens neanderthalensis existed about 100,000 years ago and had a brain capacity of 1300cc-1600cc; it is believed that he buried his dead with flowers and tools and he may have had a religion. Homo sapiens neanderthalensis evolution did not result in the creation of the era of Homo sapiens.
-The modern man stage includes Homo sapiens fossilis and Homo sapiens sapiens. Homosapiens fossilisalso known as Cro-magnon is regarded as the most recent ancestor of today's man, it had a brain capacity of 1650cc. A number of cave paintings done by Cro-magnon man have been discovered, the Cro-magnon was the direct ancestor of the living modern man. Prehistoric cave art developed about 18,000 years ago.
-About 25000 years ago Homo sapiens sapiens appeared in the Holocene epoch and started spreading all over the world about 10,000 years ago. Agriculture came around 10,000 years ago and human settlement started. The modern-man underwent cultural evolution.
-Dryopithecus falls under a different stage of modern man evolution path, whereas
Ramapithecus, Kenyapithecus, Australopithecus are under different stage
-Thus, all are ape-men stages in the origin of a man except Dryopithecus, because it belongs
to the ape stage therefore the correct answer is option C.

Note:- Paleolithic is known as the age of tools, bones, and cave paintings. Mesolithic age of animal husbandry, development of language reading and writings. Neolithic age is known as the age of development of agriculture, manufacture of pottery, and clothes. Bronze age followed by iron age.The evolutionary journey to modern humans ends with the appearance, about five hundred thousand years ago, of Homo sapiens or wise man, our own species.
