Comparison of the pelvic dimensions reported for hominin and modern human female pelves [17, 25, 30, 33, 34, 36, 37].

A.L. 288-1^a measures are from Tague and Lovejoy [17].

The range reported for A.L. 288-1^b is from two versions of the Häusler and Schmid [25] A.L. 288–1 reconstruction. The sagittal midplane measure for Sts 14 is an estimate from Berge and Goularas [30] as the Sts 14 sacrum is fragmentary and required reconstruction. Sts 65 measures from Claxton et al., [33]. MH2 measures from Kibii et al. [42].

*BSN 49/P27 outlet A-P dimension estimated based on work by Bonmati et al. [44].

Tabun 1^c measures from Ponce de León et al. [36] and the measures for Tabun 1^d are from Weaver and Hublin [37].

Three published modern human samples are shown to encompass the range of variation in modern humans [^e[17], ^f[34]; ^g[42]]. Pan troglodytes measures from Abitbol [16] and Berge and Goularas [30]. All measurements are in millimeters.
