Lucy was clearly bipedal, although she may have continued to locomote through trees (i.e., arboreal locomotion) with some ease. Scientists can deduce this information from her skeleton, which is a combination of derived human-like features and retained primitive chimpanzee-like features. Each section below discusses aspects of Lucy's anatomy that help us determine her mode of locomotion.
