Question

How would you justify that australopithecines were human ancestors?
​

Answer 1

Explanation:

Australopithecus averaged about 120 cm tall, and the cranial capacity ranged from 450-600 cm3. It had a low forehead, protruding face, lack of chin and low brain capacity. Teeth resembled man because the dental arc was a smoothly rounded parabola, and a simian gap was absent which justifies a human ancestor.
