AbstractA new method for the determination of adult skeletal age at death based upon chronological changes in the auricular surface of the ilium is presented. Formal stages have been constructed following extensive tests and refinements in observations made of such changes. Two completely “blind” tests were conducted to assess the accuracy and bias of the new metho...... hiện toàn bộ

AbstractThe aim of this study was to develop a comprehensive evidence‐based atlas to estimate age using both tooth development and alveolar eruption for human individuals between 28 weeks in utero and 23 years. This was a cross‐sectional, retrospective study of archived material with the sample aged 2 years and older having a uniform age and sex distribution. Devel...... hiện toàn bộ
AbstractTooth wear records valuable information on diet and methods of food preparation in prehistoric populations or extinct species. In this study, samples of modern and prehistoric hunter–gatherers and agriculturalists are used to test the hypothesis that there are systematic differences in patterns of tooth wear related to major differences in subsistence and f...... hiện toàn bộ
AbstractThe postcranial skeleton of Australopithecus afarensis from the Hadar Formation, Ethiopia, and the footprints from the Laetoli Beds of northern Tanzania, are analyzed with the goal of determining (1) the extent to which this ancient hominid practiced forms of locomotion other than terrestrial bipedality, and (2) whether or not the...... hiện toàn bộ

AbstractWe have measured the 14C content of human femoral mid‐shaft collagen to determine the dynamics of adult collagen turnover, using the sudden doubling and subsequent slow relaxation of global atmospheric 14C content due to nuclear bomb testing in the 1960s and 1970s as a tracer. 14C measurements w...... hiện toàn bộ
AbstractMeasurements were taken on the upper and lower molars of 37 species of primates and one tupaiid to assess the relative importance of shearing, crushing and grinding features.Significant correlations were found between pairs of allometrically standardized dimensions which measure the same molar function (shearing, crushing, or grinding). Cor...... hiện toàn bộ
AbstractAmong primitive peoples dental attrition appears to be a natural phenomenon. Often the degrees and kinds of tooth wear vary from population to population. This variability is possibly related to certain material aspects of culture such as diet, food preparation techniques and tool usage. In order to learn more about these relationships, extensive cross cult...... hiện toàn bộ

AbstractCarbon (13C/12C) and nitrogen (15N/14N) stable isotope ratios were longitudinally measured in fingernail and hair samples from mother‐infant pairs where infants were exclusively breastfed (n = 5), breast‐ and formula‐fed (n = 2), or exclusively formula‐fed (n = 1) from birth...... hiện toàn bộ
