Reassessing manual proportions in Australopithecus afarensis.

A resampling approach that includes the entire assemblage of complete hand elements at Hadar, and takes into account uncertainties in identifying phalanges by individual, side and digit number provides the most conservative estimates of manual proportions in Au.

Here we describe the functional morphology of the Australopithecus sediba hand, including the almost complete hand of the presumed female Malapa Hominin (MH) 2 skeleton and a single, juvenile

Human-like hand use in Australopithecus africanus

Australopithecus africanus and several Pleistocene hominins have a human-like trabecular bone pattern in the metacarpals consistent with forceful opposition of the thumb and fingers typically adopted during tool use, and these results support archaeological evidence for stone tool use in australopiths and provide morphological evidence that Pliocenehominins achieved human- like hand postures much earlier and more frequently than previously considered.

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.

Characterizing the body morphology of the first metacarpal in the Homininae using 3D geometric morphometrics

The modern human MC1 is characterized by a distinct suite of traits, not present to the same extent in the great apes, that are consistent with an ability to use forceful precision grip.

The expression of bilateral asymmetry in the hands and humeri : a methodological comparison

The results of this study recommend the adoption of a more inclusive approach to the study of upper limb bilateral asymmetry, particular when inferences are to be made regarding handedness.

The locomotor anatomy of Australopithecus afarensis.

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.

Functional and morphological affinities of the subadult hand (O.H. 7) from Olduvai Gorge.

A number of features of the thumb and the distal phalanges suggest that the O.H. 7 individual was capable of more precise manipulation that extant apes.

Fossil Hand Bones from Olduvai Gorge

IN Nature of December 17, 1960, Dr. L. S. B. Leakey reported on the discovery of a number of fossil bones of the hand and the foot on a living floor some 20 ft. below the uppermost limit of Bed I,

Comparisons between the hominids and African pongids clearly illustrate the anatomical and mechanical changes that occurred in this joint as a consequence of the evolutionary transition to habitual bipedality.

These values appear to be consistent with the range of size variation seen in the entire postcranial samples that can be assigned to species, and probably those equations based on the human samples are better than those based on all Hominoidea.

This work supports the model of Napier that identified morphological correlates of precision and power grasping in the hands of extant primates and in early hominid hand bones, and questions both the underlying rationale and attempts to identify more subtle aspects of precision grasping, based on present evidence.

A new study of the scapula of Australopithecus africanus from Sterkfontein

Several hypotheses, based mainly on features of the coracoid process, are presented for testing: the gracile australopithecine thoracic shape, scapular placement and angulation of the clavicle to the scapula more closely resembled the condition in extant Pongidae than that in modern man.

Biometrical characteristics of primate hands

The lenght proportions of the primate hands and their elements are analyzed in 43 extant genera and 6 fossil genera, finding that paraxony is the most frequent pattern of the simiiform hand, whereas hypermesaxony characterizes humans, hylobatids, and tarsiers.
