New hominin first metatarsal (SK 1813) from Swartkrans

A recently recognized hominin hallucal metatarsal, SK 1813, from Swartkrans bears a suite of primitive and derived traits. Comparisons with extant apes, modern humans, SKX 5017, and Stw 562 reveals similar morphology in all three fossils and that these early hominins, while bipedal, possessed a uniq...

Description
Summary:A recently recognized hominin hallucal metatarsal, SK 1813, from Swartkrans bears a suite of primitive and derived traits. Comparisons with extant apes, modern humans, SKX 5017, and Stw 562 reveals similar morphology in all three fossils and that these early hominins, while bipedal, possessed a unique toe-off mechanism. The implications of this are that both primitive and derived traits must be used to establish the total biomechanical pattern.
