The origin and evolution of man, Homo sapiens, have been a topic of great biolo­gical interest since time immemorial. The idea that man is a creation of a super­natural power prevailed for long time in earlier days.
The use of tools appears to have evolved first which preceded the increase of size of brain. Both these were accompanied by the change from four- footed gait to bipedal erect posture.

1. Introduction to Origin of Man:

The origin and evolution of man, Homo sapiens, have been a topic of great biolo­gical interest since time immemorial. The idea that man is a creation of a super­natural power prevailed for long time in earlier days.

ADVERTISEMENTS:

But the Biologists view the origin of man using knowledge on mor­phology, physiology, embryology and fossil records. Man evolved from some unknown mammalian ancestor and reached the pin­nacle of evolutionary fabric.

Man is placed under the family Hominidae of the order Primate and differs from other anthropoid apes by having: Large size of brain with greater functional ability (Maximum in Gorilla = 650 c.c., Minimum in Man = 1000 c.c.) The brain case is larger than face region.

The face is flatter with less protruding lower jaw. Continuous growth of long hair on head which are spare and short on body. Generalized hands with better developed thumbs and long leg with non-opposable big toe. Man is terrestrial in habit and walks erect on two feet. They surpass all other animals by possessing the ‘human features’ which are exclusive for them.
