Show Answer

Answer:

Correct Answer: C

Solution:

[c] Binocular vision, smaller jaw and upright posture are the main adaptations that lead to evolution of man from its ancestors.

But during human evolution major and most significant changes occurred in the cranial capacity of man.

In living modem man it is about 1450 cc compared to 500 cc in Australopithecus.

Increased cranial capacity accommodates larger brain and forms the basis of social, cultural and educational evolution of modem man.
