OBJECTIVES: Laboratory studies have yielded important insights into primate locomotor mechanics. Nevertheless, laboratory studies fail to capture the range of ecological and structural variation encountered by free-ranging primates. We present…
Jaw-joint height (JJH) above the occlusal plane is thought to be influenced by cranial base angle (CBA) and facial angulation during growth. To better understand how JJH relates to midline craniofacial form, we test the hypothesis that relative…
Despite the importance that concepts of arboreal stability have in theories of primate locomotor evolution, we currently lack measures of balance performance during primate locomotion. We provide the first quantitative data on locomotor stability in…
OBJECTIVES: Relatively long digits are considered to enhance grasping performance in primates. We tested whether growth-related changes in intrinsic hand and foot proportions may have behavioral implications for growing animals, by examining whether…
Free-ranging primates are confronted with the challenge of maintaining an optimal range of body temperatures within a thermally dynamic environment that changes daily, seasonally, and annually. While many laboratory studies have been conducted on…
Characterization of the nature and skeletal distribution of gout was accomplished in a Chamoru (Chamorros) population with predilection to the disease. Uniform excavation by the gouty diathesis produces a punched-out appearance to these predominantly…
This study was conducted to determine whether individual bony lesions are specific for recognizing multiple myeloma and thereby distinguish it from metastatic cancer and leukemia. The lytic skeletal lesions of multiple myeloma are characterized by…
The present study addresses the specificity of lyric osseous impact for distinguishing among metastatic cancer, tuberculosis, and fungal disease. Osseous impact is used in this manuscript as a convention to describe the macroscopic appearance of…
The reliability of visual examination of defleshed bones was assessed for detection of postcranial metastatic disease in individuals known to have had cancer. This was compared with standard clinical radiologic techniques. The skeletons of 128…
At least 29 species of fossil primates have been referred to fruit, nectar, and/or exudate feeding dietary niches. Many studies have detailed the morphological correlates of fruit feeding in comparison to insectivory and folivory. In contrast, few…
Dental microwear analysis has been employed in studies of a wide range of modern and fossil animals, yielding many insights into the biology/ecology of those taxa. Paleoanthropological studies have produced both expected and unexpected results (e.g.,…
The importance of locomotion to evolutionary fitness has led to extensive study of primate locomotor behavior, morphology and ecology. Most previous research has focused on adult primates, but in the last few decades, increased attention to locomotor…
The paleopathological study of human osteological remains from the site of Semna South, of northern Sudan, revealed that about thirteen percent of this ancient Nubian population had diffuse idiopathic skeletal hyperostosis (DISH). As in modern cases,…
