Question

How many of the following statements are correct?

I - Two mya, Australopithecines probably lived in East African grasslands.
II - Brow ridges have become more prominent in the course of human evolution
III - Dryopithecus showed quadrupedalism
IV - Non protruding jaws is a feature of Homo sapiens

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

Human evolution is the evolutionary process that led to the emergence of Homo sapiens as a distinct species of the hominid family.

Two million years ago, Australopithecines probably lived in East African grasslands. They hunted with stone weapons but they ate fruits.

Many changes have taken place during the course of human evolution in which the reduction of brow ridge is considered to be an important one.

The bony ridge over the eye sockets (orbits) is called brow ridge. It has undergone significant changes. It has become smaller and less prominent in the course of human evolution.

Dryopithecus showed quadrupedalism which means they walked on their four limbs.

Homo sapiens have an orthognathous face (Face without protruding jaw).

Hence, three statements (statements I, III and IV) are correct.
