3 Million Year Old Man’s Bones Discovered: How Ancient Humans Walked on Two Legs

Extinct Human Ancestor Walked Upright: Evidence from 50 Years Ago

Journalist Maria Temming recently announced that an anthropologist, D. Carl Johanson, discovered a 3-million-year-old man’s skull fragment and thigh and shin bones in Ethiopia. The bones belonged to an ape man (hominid) of the genus Australopithecus. This discovery provides concrete evidence that our ancestors walked on two legs over 3 million years ago, according to the scientist who made the announcement at a news conference.

Fossil analyses suggest that several hominid species walked around on two legs about 5 million to 7 million years ago. However, not all paleoanthropologists are convinced that those features prove a two-legged gait. Some scientists believe that an upper leg bone from the oldest known hominid species, Sahelanthropus tchadensis, may have been used for both walking and climbing trees. The bone bears signs of upright walking, including an inner projection near the hip joint.

The discovery of this ancient bone has sparked controversy among paleoanthropologists, as some are skeptical about its authenticity and whether it is truly from a human ancestor or simply an ape with some human characteristics. Nonetheless, this new evidence adds to our understanding of our ancestors’ behavior and may help us better understand how they evolved into modern humans over time.
