Recent studies have indicated that Lucy, an Australopithecus afarensis fossil, could walk upright and might have had the ability to run, though only in short bursts. While she stood about three and a half feet tall and weighed between 29 and 93 pounds, her body composition suggested she was not built for long-distance running as modern humans are. The research emphasized a significant evolutionary adaptation in humans for running long distances, which aided in hunting. Computer simulations were used to analyze her skeletal and muscular structure, aligning her capabilities with her physical traits.
Lucy, an early human ancestor, was capable of standing and walking upright, similar to modern humans, but struggled with running long distances.
A new study suggests Lucy could run, but likely only through short bursts of energy and was much slower than contemporary humans.
