Curved spine

This partial skeleton consists of several thoracic and lumbar vertebrae, a pelvis, a sacrum, and pieces of a rib and a femur. The vertebrate show this species walked upright in a way very similar to modern humans. The uniquely human curve of your lower back absorbs shock when you walk. This early human's spine had the same curve.
