Answer: small brain, small teeth, at least some bipedal ability

members of the genus Australopithecus are indicative of small brain, small teeth, at least some bipedal ability.

The genus name Australopithecus means "southern ape," based on the first fossils found in South Africa which was characterized by a combination of humanlike and apelike traits. They were similar to modern humans in that they can walk on two legs (bipedal) but, they had small brains like apes. Their canine teeth were smaller and their cheek teeth were larger than those of modern humans.

small brain, large teeth, at least some bipedal ability

Explanation:

Unlike chimpanzees, australopithecs did not walk on four legs: they were definitely bipedal. The brains of most known Australopithecus species were 35% smaller than Homo sapiens and a skull not significantly larger than a current chimpanzee.

As for size, these animals were small, generally not exceeding 1.2 m in height. The teeth and jaw were also different, much larger and heavier than those of humans.

In summary, we can say that australopithecians had: small brain, large teeth, at least some bipedal ability.
