Question

(Q018) While studying with you for an exam, a classmate claims that the only difference between australopithecines and early Homo species is that the latter had a bigger brain. What example could you give to demonstrate that there are other differences?

Answer 1

Homo species have differences in brachial index, face and teeth size as compared with australopithecines.

Step-by-step explanation:

Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.

Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
