How were australopithecines different from primates?

As characterized by the fossil evidence, members of Australopithecus bore a combination of humanlike and apelike traits. They were similar to modern humans in that they were bipedal (that is, they walked on two legs), but, like apes, they had small brains.

Do Australopithecus have large brains?

They walked upright, had brains that were around 20% larger than those of chimpanzees, and may have used sharp stone tools.

What feature does Australopithecus afarensis share with other apes?

Australopithecus afarensis characteristics afarensis possessed both ape-like and human-like characteristics. The top of its skull (the cranial vault) was slightly domed and its brain was comparable in size to a chimpanzee’s. Its face projected outwards, less so in females than in males.

How are Australopithecus different from chimpanzees?

This fossil had an ape-sized brain but a short face with smaller front teeth, including a small, human-like canine tooth much smaller than the projecting ones of apes, and larger back teeth (molars) than those of apes.

Are Australopithecus carnivores?

Despite the carnivorous preferences of their contemporaneous predators, Au. africanus individuals had a diet similar to modern chimpanzees, which consisted of fruit, plants, nuts, seeds, roots, insects, and eggs.

What is the cranial capacity range of apes?

Cranial capacities of living prosimians, monkeys, and gibbons overlap and together range between 1 and 205 cm3, which is separate from the great ape range of 275–752 cm3 (Falk 1986) (Figure 9.1 ).

What are the cranial features of Australopithecus afarensis?

The cranial features of Australopithecus afarensis were poorly adapted to chewing, grinding, and crushing. The genus Homo did not appear until after all of the australopithecines had died off.
