What are the features of the external structure of Australopithecus.

Australopithecus – two-legged ape-men.
To determine the physical type of Australopithecus, emphasis can be made on the following features: bipedalism, small brain, large teeth with thick enamel, small canines, the absence of a complex of features in the structure of the upper limbs, which are associated with the production of artificial stone tools. Depending on antiquity and biological specialization, morphological characteristics can vary quite significantly. Recent finds have determined the chronological boundaries of the existence of all known types of Australopithecus from 1 to 7 million years.
