Figure 5. — Approximate body proportions of Homo sapiens, Ardipithecus ramidus (4.4 MYA hominin, probable life appearance), and Pan troglodytes (chimpanzee). The figures are aligned at the crown of the head and the umbilicus to approximate a constant trunk length. Relative to trunk length, humans have the longest legs and shortest arms.
