Abstract
New stature estimates are provided for A.L.288‐1 (Australopithecus afarensis) based on (1) the relationship between femur length and stature in separate samples of human pygmies and pygmy chimpanzees and (2) model II regression alternatives to standard least‐squares methods. Estimates from the two samples are very similar and converge on a value of approximately 3′6″ for “Lucy.” These results are compared to prior estimates and extended to other small‐bodied hominids such as STS‐14 and O.H.62. A new foot‐to‐stature ratio is also estimated for A.L.288–1, and its potential biomechanical significance for gait is evaluated in comparison to other groups.
