Question

Which ancestor of man had a cranial capacity ranging from 450 - 600 cm${}^3$?

• A. Cro - Magnon man
• B. Australopithecus
• C. Homo erectus
• D. Ramapithecus

Answer 1

The correct option is B

Australopithecus

Australopithecus was the ancestor of man that had a cranial capacity ranging from 450 - 600 cm${}^3$. It was also the first human ancestor to exhibit bipedalism. This revolutionary change freed the forelimbs i.e., arms and hands for grasping objects such as food and perhaps young ones. They could also look around for food and predators more easily, and were also able to run away from huge carnivores lurking around them.
