Human Anatomy Postcranial Elements. Articular area responses to mechanical loading: effects of exercise, age, and skeletal location. Comparative 3D quantitative analyses of trapeziometacarpal joint surface curvatures among living catarrhines and fossil hominins. Estimating body mass from the astragalus in mammals. The goals of this research are to provide an objective hierarchy of sexing effectiveness of cranial and postcranial elements and to test the widespread notion that the skull is superior to postcranial bones. Spiros’s research focuses on macromorphoscopic (MMS) variation in the postcranial skeleton, which involves examining the expression of human variation in the skeleton below the skull.

There are separate forms for the documentation of cranial and postcranial lesions, to account for special implications from the spherical architecture of the skull. Professor Tracy Kivell is a palaeoanthropologist who studies the evolution of the postcranial skeleton in living and fossil primates, including our human ancestors (hominins). This chapter will describe the process of a functional morphological analysis of lever mechanics including: identification of dominant muscles and assessing the action of those muscles based on comparative anatomy, identification of in-levers and out-levers, measurement of lever arms, and statistical analysis. Hominoid species are particularly valuable, because counts of total numbers of vertebrae, and hence original somite numbers, are available for large samples.

Current studies in this field are largely unchanged from those of the late 1900s, the largest steps forward being in the ability to analyze large, multivariate datasets, and quantify complex shapes due to leaps in computing power, and in the development of methods to account for phylogenetic signal in morphological data. Secular change in height has been extensively investigated, but size and shape of the postcranial skeleton much less so. However, most publi- determination from multiple postcranial bones yields a higher proba- cations in the forensic anthropological literature of postcranial sex bility accuracy than sex determination from the skull’’ (4, p. 194).
