TABLE 1.

Pelvic dimensions relative to body size in Au. afarensis A.L. 288–1, “Lucy,” and modern human females

	Lucy (female Au. afarensis)	Modern human female
Pelvic inlet width (mm)	123–1323,4,7	124–1323–5,7
Femur length (mm)	280–2862,5,8	380–4411,2,5
Inlet width/mass1/3	4.46	3.56

The pelvis in A.L. 288–1, although similar in medio-lateral dimensions to that of a modern human female, is much wider relative to limb length and body size. Modern human data are means from various populations.
