title: "Lucy's" body height and relative leg length: human- or ape-like?
abstract: The body height of Australopithecus afarensis A.L. 288-1 ("Lucy") has recently been estimated and calculated as between 1 m to 1.06 m; other estimates give ca. 1.20 m. In addition, it is often stated that her relative leg length was shorter than that of modern humans. Using relative leg-, femur- and tibia length it is shown that both statements together can not be true; either her body height must at least have been around 1.06 to 1.10 m to give "Lucy" human-like leg proportions, or, to achieve a shorter, more ape-like leg ratio, a body height of ca. 1.20 m must be assumed.
