Effects of pubertal growth variation on knee mechanics during walking in female and male adolescents
Pubertal growth variation has important effects on mechanical knee injury risk in adolescence, affecting females and males differently. Earlier developing females exhibit greater injury risk via frontal plane factors, whereas later/faster developing males have elevated risk via sagittal plane mechanisms
Physical activity and time budgets of Hadza forager children: Implications for self‐provisioning and the ontogeny of the sexual division of labor
OBJECTIVES: To determine the effects of age and sex on physical activity and time budgets of Hadza children and juveniles, 5-14 years old, including both in-camp and out-of-camp activities. METHODS: Behavioral data were derived from ~15 000 hourly in-camp scan observations of 76 individuals and 13 out-of-camp focal follows on nine individuals. The data were used to estimate energy expended and percentage of time engaged in a variety of routine ac…
The ontogeny of nasal shape: An analysis of sexual dimorphism in a longitudinal sample
OBJECTIVES: Potential integration between the nasal region and noncranial components of the respiratory system has significant implications for understanding determinants of craniofacial variation. There is increasing evidence that sexual dimorphism in body size and associated male-female differences in energetically relevant variables influence the development of the nasal region. To better understand this relationship, we examined the ontogeny …
Ontogenetic scaling of the human nose in a longitudinal sample: Implications for genus Homo facial evolution
Researchers have hypothesized that nasal morphology, both in archaic Homo and in recent humans, is influenced by body mass and associated oxygen consumption demands required for tissue maintenance. Similarly, recent studies of the adult human nasal region have documented key differences in nasal form between males and females that are potentially linked to sexual dimorphism in body size, composition, and energetics. To better understand this pote…
Skeletal growth and the changing genetic landscape during childhood and adulthood
Growth, development, and decline of the human skeleton are of central importance to physical anthropology. All processes of skeletal growth (longitudinal growth as well as gains and losses of bone mass) are subjected to environmental and genetic influences. These influences, and their relative contributions to the phenotype, can be asserted at any stage of life. We present here the gross phenotypic and genetic landscapes of four skeletal traits, …
Postmenopausal Health and Disease from the Perspective of Evolutionary Medicine
Menopause normally occurs between 45-55 years of age, marks the end of a woman's reproductive lifespan, and is accompanied by a reduction in estrogen that has substantial physiological effects. The standard medical view is that these changes underlie high postmenopausal disease rates, defining menopause as an estrogen deficiency condition needing treatment. This view stems from the idea that extended postmenopausal longevity is a consequence of r…
Applying new approaches to modeling diet and status: Isotopic evidence for commoner resiliency and elite variability in the Classic Maya lowlands
Multivariate carbon and nitrogen stable isotope model for the reconstruction of prehistoric human diet
Using a sample of published archaeological data, we expand on an earlier bivariate carbon model for diet reconstruction by adding bone collagen nitrogen stable isotope values (δ 15 N), which provide information on trophic level and consumption of terrestrial vs. marine protein. The bivariate carbon model (δ 13 C apatite vs. δ 13 C collagen ) provides detailed information on the isotopic signatures of whole diet and dietary protein, but is limited…

Climate variables as predictors of basal metabolic rate: New equations
Estimation of basal metabolic rate (BMR) and daily energy expenditure (DEE) in living humans and in fossil hominins can be used to understand the way populations adapt to different environmental and nutritional circumstances. One variable that should be considered in such estimates is climate, which may influence between‐population variation in BMR. Overall, populations living in warmer climates tend to have lower BMR than those living in colder …
Intraspecies variation in BMR does not affect estimates of early hominin total daily energy expenditure
We conducted a meta-analysis of 45 studies reporting basal metabolic rate (BMR) data for Homo sapiens and Pan troglodytes to determine the effects of sex, age, and latitude (a proxy for climate, in humans only). BMR was normalized for body size using fat-free mass in humans and body mass in chimpanzees. We found no effect of sex in either species and no age effect in chimpanzees. In humans, juveniles differed significantly from adults (ANCOVA: P …

The ontogeny of nasal shape: An analysis of sexual dimorphism in a longitudinal sample
OBJECTIVES: Potential integration between the nasal region and noncranial components of the respiratory system has significant implications for understanding determinants of craniofacial variation. There is increasing evidence that sexual dimorphism in body size and associated male-female differences in energetically relevant variables influence the development of the nasal region. To better understand this relationship, we examined the ontogeny …
