Multivariate analyses of the acetabular and iliac parts of fossil hominid and extant hominoid pelvic bones show that (1) the best preserved fossil from Swartkrans (SK 3155) is more similar to the Sterkfontein pelvis (Sts 14) than either fossil is to any extant hominoid species; (2) of the living hominoids, all of the fossils are closer to modern Homo sapiens than to the apes; and (3) the robust and gracile forms of South African australopithecines are somewhat different from one another, the gracile form falling nearer to Homo sapiens, but neither form demonstrably closer to the pongids.
（1）来自斯瓦特克朗斯的保存最完好的化石（SK 3155）与斯特克方丹骨盆（Sts 14）的相似性高于这两种化石与任何现存类人猿物种的相似性；（2）在现存类人猿中，所有化石与现代智人的亲缘关系都比与猿类更近；（3）南非南方古猿的粗壮型和纤细型彼此略有不同，纤细型更接近智人，但两种类型都没有明显更接近猩猩科动物。
