A team of researchers have reconstructed the muscle mass of a million-year-old hominin skeleton known as Lucy, believed to have lived in what is now Ethiopia. This is the first time that Lucy’s muscles have been reconstructed, and the results could offer insight into the locomotion of early humans. The team used both digital imaging and 3D models to analyze the bones of Lucy, the most complete Australopithecus afarensis skeleton ever discovered. The results showed that Lucy’s muscles were similar to those of modern humans, but with some key differences that could help explain how our ancient ancestors moved around. The findings could help us understand more about the locomotion of early humans, and how they evolved over time.
