StW 573, from Sterkfontein Member 2, dated ca 3.67 Ma, is by far the most complete skeleton of an australopith to date. Joint morphology is in many cases closely matched in available elements of Australopithecus anamensis (eg. proximal and distal tibial and humeral joint-surfaces) and there are also close similarities to features of the scapula, in particular, of KSD-VP-1/1 A. afarensis from Woranso-Mille. The closest similarities are, however, to the partial skeleton of StW 431 from… Expand
The long limb bones of the StW 573 Australopithecus skeleton from Sterkfontein Member 2: Descriptions and proportions.
TLDR
The multivariate allometric analysis suggests that limb lengths of Australopithecus, as represented by StW 573 and A.L. 288-1, exhibit a significantly different allometric pattern than that which typifies modern humans and African apes, and suggests that hominin limb evolution occurred in two stages.

The Long Limb Bones of the StW 573 Australopithecus Skeleton from Sterkfontein Member 2: Descriptions and Proportions
TLDR
The first descriptions of that skeleton’s upper and lower long limb bones are provided, as well as a comparative context of its limb proportions, which suggest that hominin limb evolution occurred in two stages with a modest increase in lower limb length and a concurrent shortening of the antebrachium. Expand
The partial skeleton StW 431 from Sterkfontein - Is it time to rethink the Plio-Pleistocene hominin diversity in South Africa?
TLDR
Questions are raised whether it is justified to subsume hominins from Taung, Makapansgat and Sterkfontein (and Gladysvale) within a single taxon and given the wealth of fossil material and analytical techniques now available, it is called for a re-evaluation of the taxonomy of South African Plio-Pleistocenehominins.

A Three-Dimensional Musculoskeletal Model of the Western Lowland Gorilla Foot: Examining Muscle Torques and Function
TLDR
This work presents the first 3D musculoskeletal computer model of a western lowland gorilla foot, giving muscle torques about the tarsometatarsal, metatarsophalangeal and interphalangeal joints of digits 2–5, and reports, for the first time, interossei acting upon proximal and distal interphalanges joints. Expand
Birth of Australopithecus
TLDR
An account of anatomist Raymond Dart's training and experience is combined with a telling of the fossil's discovery, analysis, the initial response of a mostly skeptical community, and a review of subsequent discoveries that consolidated the case Dart made for a hitherto unknown human close relative. Expand
‘Little Foot’ hominin emerges from stone after millions of years
TLDR
Scientists are starting to piece together the evolution of a 3.67 million-year-old early human who may have been among the first to walk like the authors do after a 20-year excavation. Expand

The Long Limb Bones of the StW 573 Australopithecus Skeleton from Sterkfontein Member 2: Descriptions and Proportions
TLDR
The first descriptions of that skeleton’s upper and lower long limb bones are provided, as well as a comparative context of its limb proportions, which suggest that hominin limb evolution occurred in two stages with a modest increase in lower limb length and a concurrent shortening of the antebrachium. Expand
The skull of StW 573, a 3.67 Ma Australopithecus skeleton from Sterkfontein Caves, South Africa
TLDR
The first full anatomical description of the 3.67 million-year-old Australopithecus skull StW 573 is presented, and it is concluded that competitive exclusion probably accounts for the synchronous and sympatric presence of two species of Australipithecus in the younger deposits at Makapansgat and Sterkfontein Member 4. Expand
Contours of the hominoid lateral tibial condyle with implications for Australopithecus.
TLDR
Three-dimensional surface areas of the lateral tibial condyle of humans, chimpanzees, and gorillas were computed using a Digibot II laser scanner and the DataSculpt v.4.6 engineering software package to evaluate joint surface contours and results do not support the hypothesis that joint surfaces become flatter with increased transarticular load accompanying increased body size. Expand
The context of Stw 573, an early hominid skull and skeleton from Sterkfontein Member 2: taphonomy and paleoenvironment.
TLDR
The taphonomic conclusion that animals with climbing proclivities (i.e., primates and carnivores) are preferentially preserved over other taxa, ultimately because of those proclivity, urges caution in assessing the fidelity of the assemblage for reconstruction of the Member 2 paleoenvironment. Expand
The third partial skeleton of a late Pliocene hominin (Stw 431) from Sterkfontein, South Africa §
TLDR
The skeleton shows an interesting complex of primitive and derived features, throwing further light on the mosaic character of hominin evolution, and supports suggestions that the australopithecines, although adapted for bipedalism, were not consistent or obligate bipeds. Expand
Interpretation of footprints from Site S confirms human-like bipedal biomechanics in Laetoli hominins.
The recent discovery of additional hominin footprints at Laetoli (Masao et al., 2016) offers a rare opportunity to revisit the biomechanics of bipedalism in early hominins, a trait that was aExpand
The endocast of StW 573 ("Little Foot") and hominin brain evolution.
TLDR
The first detailed comparative description of the external neuroanatomy of StW 573 is presented, which approximates the rostrocaudally elongated and dorsoventrally flattened endocranial shape seen in Australopithecus and displays a distinct left occipital petalia. Expand
Forelimb segment length proportions in extant hominoids and Australopithecus afarensis.
TLDR
Pan species are unique in having long metacarpals relative to ulnar length, demonstrating that they probably differ from the common chimp-human ancestor, and also that developmental mechanisms can be altered to results in differential growth of individual forelimb segments. Expand
The locomotor anatomy of Australopithecus afarensis.
TLDR
It is demonstrated that A. afarensis possessed anatomic characteristics that indicate a significant adaptation for movement in the trees, and it is speculated that earlier representatives of the A.Afarensis lineage will present not a combination of arboreal and bipedal traits, but rather the anatomy of a generalized ape.

TLDR
By taking into account the retained complex asymmetry of motion of the human knee, such as the differentially greater femoral rollback of the lateral compartment as compared with the medial compartment, external bracing systems and designs for total knee replacement might be improved. Expand
