jan 1, 3997982 BC - Australopithecus
The Australopithecus were the threshold between ape and closer to human than ever before. Some unique features were that the Australopithecus were the first bipeds which means that they mainly walked on two feet instead of four. Also they surprisingly they didn't have foreheads. the third unique feature is they shared the same type of pelvis bone with humans, I mean they didn't exactly share the same but it was more similar than the chimps pelvis bone compared with the Australopithecus. this information is comming from the picture I have.
