Gorillas and chimps weren't around when the Australopithecines was
NO
Homo erectus coexisted with several species of australopithecines including Australopithecus afarensis, Australopithecus africanus, and possibly Australopithecus garhi. These australopithecines lived before the appearance of Homo erectus and were part of the evolutionary lineage that eventually led to humans.
The Australopithecines did not have religion or ceremonies. The earliest evidence for brain development sufficient to allow symbolic behaviour and these kind of behaviours is associated with Neanderthal which appeared 600,000 years after the last Australopithecines disappeared.
they didnt invent anything
Chimpanzees are mammals. Because of that, they have a backbone. Therefore, Chimpanzees are vertebrates.
It's commonly thought that Australopithecines had no language ability. But even if they did, we would have no way of knowing anything about it, since it would not have been written.
These are some of the names anthropologist use to classify 'cavemen'.Australopithecines (Robustus) Australopithecines (Gracile) Australopithecus Cro-Magnon Homo Habilis
Homo habilis was contemporaneous with australopithecines but had a significantly larger brain, indicating a more advanced level of cognitive capabilities and tool use.
Australopithecines were like modern humans in some ways because they walked upright on two legs, had similar hands and teeth, and lived in social groups. However, they also had smaller brains and more primitive tools and technology compared to modern humans.
Australopithecus didn't wear any clothes
The plural form of Australopithecus is Australopithecines.
