Variation in limb proportions between prehistoric Jomon and Yayoi people of Japan are explored by this study. Jomon people were the descendents of Pleistocene nomads who migrated to the Japanese Islands around 30,000 yBP. Phenotypic and genotypic evidence indicates that Yayoi people were recent migrants to Japan from continental Northeast Asia who likely(More)
Recent studies on fluctuating dental asymmetry have isolated single stressors as causative agents. Since most stressors are composite in nature, the present study was designed to determine the effects of the interaction of stressors in the induction of fluctuating dental asymmetry. Pregnant rats were assigned to one of six treatment groups and stressed with(More)
Estimation of age-at-death of subadults in prehistoric skeletal samples based on modern reference standards rests on a number of assumptions of which many are untestable. If these assumptions are not met error of unknown magnitude and direction will be introduced to the subadult age estimates. This situation suggests that an independent estimate or(More)
The relationship between third trochanter incidence and femoral metric trait covariation has been investigated in a group of 60 left human femora. The experimental sample was constructed so that one group consisted of 15 male and 15 female femora which displayed a third trochanter and a second group consisted of an equal number of sexed long bones which(More)
Previous studies have suggested that Neandertals experienced greater physiological stress and/or were less capable of mitigating stress than most prehistoric modern human populations. The current study compares estimates of dental fluctuating asymmetry (DFA) for prehistoric Inupiat from Point Hope Alaska, the Late Archaic, and Protohistoric periods from(More)
Linear enamel hypoplasia (LEH) is an enamel defect that records the effects of physiological stress on tooth formation. Estimating the age at which LEH defects form is integral to the reconstruction of population health in bioarcheological studies. Two principal methods for aging LEH defects have been introduced in the literature. The conventional approach(More)
The phenotypic expression of adult body size and shape results from synergistic interactions between hereditary factors and environmental conditions experienced during growth. Variation in body size and shape occurs even in genetically relatively homogeneous groups, due to different occurrence, duration, and timing of growth insults. Understanding the(More)
Accurate estimates of age-at-death of subadult human skeletal remains are limited because of the dearth of information on the covariance among reliable indicators in recent samples of children. To obtain these kinds of data, namely patterns of maturation among dental development, epiphyseal union, and long bone growth, we focused on a radiographic method(More)
This study employs metric and morphological features of the deciduous dentition for discriminating between European-American and African-American children and providing allocation rules (regression equations). Five logistic regression equations are presented, with the percentage of correct allocation to group of between 90.1-92.6%. All five equations employ(More)
