Lucy’s radius is more similar to a chimpanzee than a modern human. The neck of Lucy’s radius is long and narrow, a feature typical of a chimpanzee’s upper limb. The radius in modern humans has a relatively shorter neck compared to arboreal quadrupeds. Ape-like traits in the upper limb are an indication that Lucy was adept at arboreal activity as well as moving bipedally when on the ground.
