Uni- and multivariate analyses of 5 fossil and 215 extant hominoid femora show that two morphological patterns of hominid femora existed about two million years ago. Femora classified as Homo sp. indet. (KNMER 1472 and 1481) are more like Homo sapiens although not identical. Those classified as Australopithecus robustus (SK 82 and 97) and A. boisei (KNM-ER 1503) are similar to one another but uniquely different from any living hominoid. The strong mophological constrasts imply biomechanical and possible locomotor differences, although these are as yet unknown.
对5块化石股骨和215块现存类人猿股骨进行的单变量和多变量分析表明，大约200万年前存在两种人类股骨的形态模式。被归类为智人未定种（KNMER 1472和1481）的股骨更类似于智人，尽管并不完全相同。那些被归类为粗壮南方古猿（SK 82和97）和鲍氏南方古猿（KNM-ER 1503）的股骨彼此相似，但与任何现存类人猿都有独特的差异。尽管这些差异目前尚不清楚，但强烈的形态对比意味着生物力学和可能的运动差异。
