Some Implications of Relative Biornechanical Neck Length in Hominid Femora
Demonstration of a size-based influence on relative biomechanical neck length of the femur predicts relatively longer necks for smaller femurs. Fossil hominids through the middle Pleistocene appear to have relatively longer femur necks than expected from this relation, excepting the two small australopithecine females. I t is suggested that this variation results from smaller crania a t birth i...
متن کاملFossil evidence for early hominid tool use.
Although several Plio-Pleistocene hominids are found in association with stone and bone tools, it has been generally assumed that at any one time the hominid with the largest brain was the toolmaker. Fossils recovered over the last decade suggest that early hominids subsequent to 2.5 million years ago all might have used tools and occupied "cultural" niches. A test for humanlike precision grasp...
متن کاملMusculoskeletal Stress and Adult Age Markers in the Krapina Hominid Collection: the Study of Femora
The purpose of this study was to examine morphological markers of activity and age on femora 213 Fe.1 and 214 Fe.2 of the Krapina hominid collection. This study is part of a large research on the Krapina collection aimed at studying morphological markers of activity (entheses, enthesopathies, articular modifications) and age, as well as dento-alveolar alterations and pathologies. For this purpo...
متن کاملHominid-Pongid Distinctiveness in the Miocene-Pliocene Fossil Record: The Lothagam Mandible
The Lothagam mandibular fragment, found in 1967 west of Lake Turkana, Kenya, has been dated to 5.5 million years ago. This date is significant because it may lie within the suggested time range during which the hominid and pongid clades diverged. Because of its fragmentary condition and great age, this specimen has run the gamut of taxonomic assignations, from ramapithecine to pongid to hominid...
متن کاملThe study of morphological variation in the hominid fossil record: biology, landmarks and geometry.
This review considers some recent advances in shape analysis based on landmark data, and focuses on the application of these methods to the study of skeletal evolution in primates. These advances have provoked some controversy. The major aims of this review are to put these debates in context and to provide an overview for the nonmathematician. The purpose of morphometric studies is considered,...
