Microbial osteolysis in an Early Pleistocene hominin (Paranthropus robustus) from Swartkrans, South Africa
Brief communication
Bone histomorphometry has been applied to the lower limb cortical bone of Pleistocene humans to establish age at death and to determine bone remodeling rates (Abbott et al.: Am J Phys Anthropol 226 (1996) 307–313). Both of these procedures require the determination of osteon density and mean osteon size. Previous analyses of Middle and Late Pleistocene human lower limb bones have produced bone remodeling rates that are slower than those determine…

Dynamic bone remodeling in later Pleistocene fossil hominids
Histomorphometric analysis of femoral and tibial diaphyseal fragments from seven Late Archaic and three Early Modern humans are compared with those of the Pecos, a pre-Columbian Native American population. The ten samples, from Broken Hill (EM-793), Shanidar 2, 3, 4, 5, and 6, Tabun 1, and Skhul 3, 6, and 7, provide age-at death results consistent with earlier estimates for most individuals. The Pleistocene groups exhibit less bone turnover and s…
Body size, long bone geometry and locomotion in quadrupedal monkeys
Gravitational forces place important constraints on skeletal design, including size-required modifications in bone shape and robusticity. The scaling of long bone cross sectional geometry (cortical areas, section moduli, moments of area variables related to strength in compression, bending and torsion) in quadrupedal monkeys corroborates the allometric predictions of a recent multifactorial biomechanical model for medium-sized terrestrial mammals…
Olivi's Peaceable Kingdom
Everyone who knows anything at all about Petrus Iohannis Olivi knows that his Apocalypse commentary was censured; yet opinions on that condemnation vary. The basic facts are clear. After Olivi's death in 1298, his writings were suppressed by the Franciscan order, yet his tomb at Narbonne became such a popular pilgrimage site that by the second decade of the fourteenth century the crowds were said to rival those a the Porziuncula in Assisi. In 131…

Structural adaptations of the femur and humerus to arboreal and terrestrial environments in three species of macaque
One reason to measure cross‐sectional structural properties of primate long bones is to define mechanically relevant complexes of traits that describe the adaptation of bone to different biomechanical environments. This can be effectively accomplished when congeneric species having different postural and locomotor behaviors are compared. This paper compares the cross‐sectional geometry of the femur and humerus in three behaviorally different maca…

Olivi, Apocalyptic Expectation, and Visionary Experience
If Peter John Olivi was given less than his due by previous generations of scholars, the present generation seems bent on making it up to him. Recent writers have identified him as a father of fourteenth-century nominalism, as a major architect of the dogma of papal infallibility, as a trail-blazer in economic thought, and as an astute reformer whose advice, if heeded, would have saved the church a good deal of subsequent trouble. In the process,…

Effects of age and sex on the amount and distribution of mineral in Eskimo tibiae
The bone mineral content (BMC), bone width, and cross‐sectional moment of inertia (CSMI) of 141 Alaskan Eskimo tibias were measured using photon absorptiometry. The effects of age and sex on the bones' structural properties were studied. It was found that in women, BMC decreased by 50% between the third and sixth decades, but that of the males did not decline significantly with age. This was true of the CSMI as well, for bending in both the anter…
Cortical bone maintenance and geometry of the tibia in prehistoric children from Nubia's Batn el Hajar
The relationship between advancing age in adults and patterns of cortical bone maintenance has been extensively documented for archaeological populations (Dewey, et al., 1969; Van Gerven et al., 1969; Perzigian, 1973). Most recently, this research has been expanded to include a more thorough consideration of the geometric properties of bone in relationship to adult age changes (Martin and Atkinsin, 1977; Ruff and Hayes, 1983). To date, however, f…
Primate cortical bone microstructure
Mechanical factors are implicated in the control of osteonal (Haversian) remodeling. Twenty primate species, representing a diverse range of locomotor behaviors, have been examined to determine whether the arrangement of secondary osteonal bone at femoral mid‐diaphysis reflects behaviorally related biomechanical influences. The proportion of bone cortex occupied by secondary osteons (percent osteonal bone) is related to the biomechanical environm…
Graduate education and the role of the physical anthropologist in biomedical teaching and research
There is a place for the physical anthropologist in biomedical teaching and research because of the special and unique skills possessed by this individual. However, eventual success in the health sciences environment requires the student to obtain the knowledge and background for functionally oriented teaching and research. Students interested in a biomedical teaching and research career must prepare themselves methodologically and theoretically.…
Osteoarthrosis
Examination of an Eskimo skeletal series demonstrated at least two etiologically distinct groups of joint deterioration divided along sex lines. Low bone mineral content (BMC) among women and high BMC among men were associated with osteoarthrosis on the tibial plateau. This finding contradicts conventional wisdom based on clinical observation, which suggests that reduced skeletal mass prevents osteoarthrosis
How do trabeculae affect the calculation of structural properties of bone
One difficulty that arises in an analysis of the cross‐sectional properties of bone is whether to include cancellous bone in the analysis. The purpose of this paper is to determine how different amounts of cancellous bone affect the measurement of structural properties of bone cross‐sections. Thirty‐two tibial and femoral cross‐sections were chosen at random from a series of cross‐sectioned nonhuman primate bones. Geometrical properties were calc…
Structural strength of the macaque femur
New techniques in bone mechanics, and the demonstration that locomotor function can be interpreted based on patterns of structural strength delineated by these new techniques, lay the foundation for analyses of structural strength in nonhuman primate long bones. The present paper details topographic variability in structural strength of the femoral diaphysis of Macaca as a basis for further quantifying form‐function interactions in pronograde pri…
The relationships among physical, geometrical and mechanical properties of bone, with a note on the properties of nonhuman primate bone
Since bone reacts to imposed loads by formation and resorption of tissue, analysis of tissue distribution within a bone provides evidence of the adaptation of that bone to a given mechanical function. Definition of these structure‐function relationships permits the physical anthropologist to clarify the wide variety of behavioral/morphological adaptations to specific ecological niches in extant primates. From this information, behavior and locomo…
Percentage ash content of nonhuman primate long limb bones
Trotter and Hixon ('76) and Vose and Roach ('72) presented conflicting data about percentage ash content of the long limb bones of M. mulatta and M. nemestrina . The suggestion of Trotter and Hixon ('76) that this discrepancy was due to methods of preparing the bone prior to ashing, rather than to species differences, was tested using data collected by Gong ('72) on the volumetric composition of nonhuman primate bone. Masses of the various chemic…
Patterns of variability in mineralization of the primate femoral diaphysis
The purpose of this research was to study intra‐ and interspecific variability in mineral density in the femoral diaphysis of nonhuman primates. Four hundred five sections were taken from five sites along the femoral diaphysis of 34 macaques ( Macaca sp.), 24 squirrel monkeys ( Saimiri sciureus ), and 23 tamarins ( Saguinus labiatus ). The mineral density at eight positions around each section was measured. Analysis of variance indicated signific…
Patterns of psycholinguistic development in the severely mentally retarded
We hypothesize that the loss of psycholinguistic skills in some cases of severe mental retardation caused by prenatal disruption closely approximates ontogenetic patterns of language acquisition and phylogenetic patterns of cognitive development. This hypothesis was tested on 131 trainable mental retardates divided into four etiological classes. The results support the hypothesis and show that certain patterns of loss occur only in mental retarda…

Sexual dimorphism and mechanics of the human hip
The present research was undertaken to determine the effects of sexual dimorphism in the human pelvis and femur on the mechanics of human locomotion. The analysis was based on six biomechanical variables determined from 25 male and 32 female skeletal remains from the Dickson Mound site. Discriminant function analysis indicates that the mechanical variables which primarily contribute to dimorphism are the moment arm of the gluteus medius and the t…

Further Evidence Concerning Speech in Neandertal Man
Seventeen measurements associated with the cranial base were compared for three groups: modem H. sapiens; Mesolithic H. sapiens; and two Neandertals, Skhiil V and the Rhodesian specimen. It was found that cranial base morphology was not substantially different in the Neandertals from modem and Mesolithic groups. The fact that cranial base morphology differs in any of the groups only negligibly precludes any reconstruction of Neandertal soft anato…
