 The study used a novel technique to reconstruct the soft tissue of an extinct species, Australopithexaphorensis. The technique involved creating a polygonal model of the muscles based on the shape of the bones and the muscle scars left behind. This allowed them to estimate the volume of each muscle and compare it to a modern human. They found that the muscle volumes were comparable between the two species, suggesting that they had similar capabilities when it came to moving around. This article was authored by Ashley L.A.
