New wrist bones of Homo floresiensis from Liang Bua (Flores, Indonesia).
The carpal anatomy of H. floresiensis supports the hypothesis that the lineage leading to the evolution of this species originated prior to the cladogenetic event that gave rise to modern humans and Neandertals. Expand
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. Expand
Morphological affinities of the Australopithecus afarensis hand on the basis of manual proportions and relative thumb length.
The manual proportions of Australopithecus afarensis are investigated by means of bivariate and multivariate morphometric analyses, in order to test the hypothesis that human-like proportions, including an enhanced thumb/hand relationship, originally evolved as an adaptation to stone tool-making.

The hominoid os capitatum, with special reference to the fossil bones from Sterkfontein and Olduvai Gorge
Current speculations about australopithecine hand function undoubtedly derive in large measure from the published reports on the Sterkfontein capitate. The credibility of these reports is, however,Expand
The hand of Homo naledi
The finger bones are longer and more curved than in most australopiths, indicating frequent use of the hand during life for strong grasping during locomotor climbing and suspension, and are considered adaptive for intensified manual manipulation. Expand
The differential frequency of preservation of early hominid wrist and hand bones
There is a preservation rate cline from proximal to distal in the hand, proximal elements (metacarpals) being numerically better preserved than the distal elements (proximal, middle and distal phalanges, in that order of preservation). Expand
Earliest modern human-like hand bone from a new >1.84-million-year-old site at Olduvai in Tanzania
The discovery of OH 86 suggests that a hominin with a more MHL postcranium co-existed with Paranthropus boisei and Homo habilis at Olduvai during Bed I times. Expand
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. Expand
Pattern profile analysis of hominid and chimpanzee hand bones.
  • S. Smith
  • Biology, Medicine
  • American journal of physical anthropology
  • 1995
In a study designed to complement morphological research on hominid hand bones, length and width measurements of the thumb, index, and middle rays were obtained from radiographs of modern human hands, demonstrating the promise of pattern analysis. Expand
The expression of bilateral asymmetry in the hands and humeri : a methodological comparison
The population-level preference for the use of the right hand is one of the defining characteristics of Homo sapiens and as such, its evolutionary origins within the human genus remain a topic ofExpand


The prehensile movements of the human hand.

It is shown that movements of the hand consist of two basic patterns of movements which are termed precision grip and power grip, which appear to cover the whole range of prehensile activity of the human hand. Expand
