there brain is about the size of a base ball
The brain size of ravens are on average the largest of any other bird. They have the same brain to body ratio as a chimpanzee.

The average brain size of Australopithecus species ranged from about 400 to 500 cubic centimeters, which is significantly smaller than that of modern humans. This smaller brain size reflects their more primitive cognitive abilities compared to humans.
No, Homo erectus had larger brains than Australopithecus. Homo erectus had an average brain size of around 900 cubic centimeters, while Australopithecus had a brain size of around 400-500 cubic centimeters. This increase in brain size is thought to be one of the key factors in the evolution of Homo erectus.
Australopithecus had a smaller brain size and walked upright on two legs, like humans, but had more primitive features such as longer arms and smaller overall body size. Homo habilis, on the other hand, had a larger brain size, used primitive stone tools, and had a more human-like body shape.
The smaller cranium of Australopithecus afarensis compared to Homo erectus may be due to differences in brain size and development. Australopithecus had a smaller brain capacity and may have had a less complex brain structure than Homo erectus. The differences in cranial size and shape could also be attributed to evolutionary adaptations and changes in diet, behavior, and habitat between the two species.
Australopithecus was about the size and strength of a chimpanzee.
The Australopithecus afarensis was a bipedal hominid and its brain case was only 500 cubic centimeters (about 1/3 the size of modern human brain cases). The Australopithecus afarensis lived 3.85 to 2.95 million years ago in eastern Africa.

One key feature that distinguishes the Homo genus from the Australopithecus genus is an increase in brain size and complexity. Homo species typically have larger brains relative to body size, with expanded regions for higher cognitive functions. Additionally, the Homo genus shows evidence of more advanced tool use and cultural behaviors.
Australopithecus
The most useful evidence for differentiating between Australopithecus afarensis and Homo habilis would be the shape and size of their brains, as well as the shape and size of their jaws and teeth. Australopithecus afarensis typically had a smaller brain size and more pronounced facial features compared to the larger brain size and more advanced tool use associated with Homo habilis. Dental and cranial anatomy would also be key factors in distinguishing between the two species.
