Human Evolution
That may be the case. However, some scientific experts agreed about some of the broader details of the human evolution levels. One of these that seemed clear is that at some point, in more than 5 million but less than 7 million years before the present, human being’s ancestors emerged. Ape-like creatures also began to walk upright with their two feet rather than by their hands and feet, all fours. As seen in the picture, their arms grew shorter, and their legs grew longer to accommodate their way of walking.

Australopithecus Afarensis
These human ancestors were assumed to have evolved from Australopithecus afarensis, famous for discovering the old fossil named “Lucy.” Lucy was found in Ethiopia and is already 3.2 million years old. This fossil Lucy was older than any Homo designate ever discovered. Homo designate first showed up nearby in the form of a jawbone, calculated to be about 2.8 million years old. The fossils that they found only appeared anywhere near the standard 2-million-year mark. It was during this time when several species of Homo ancestor also existed.
