Comparative primate energetics and hominid evolution.
TLDR
The ecological correlates of variation in metabolic requirements among extant primate species is examined, and inferences about the changes in energy demands over the course of human evolution are drawn. Expand
Correlates of delay-discount rates: Evidence from Tsimane' Amerindians of the Bolivian rain forest
Abstract Delay-discount rates (or rates of time preference) are associated with rates of consumption and a variety of impulsive behaviors. Despite the importance of discounting, little is known aboutExpand
Climatic influences on human body size and proportions: ecological adaptations and secular trends.
TLDR
Findings indicate that, although climatic factors continue to be significant correlates of world-wide variation in human body size and morphology, differential changes in nutrition among tropical, developing world populations have moderated their influence. Expand
Three limitations of the body mass index.
TLDR
The assumption that the BMI is independent of stature is not quite true for adults and especially not true for children, and for some age groups, at least, it may be a better measure of amount oflean than of relative fatness. Expand
15O PET Measurement of Blood Flow and Oxygen Consumption in Cold-Activated Human Brown Fat
TLDR
The objective of this study was to determine to what extent BAT thermogenesis is activated in adults during cold stress and to establish the relationship between BAT oxidative metabolism and 18F-FDG tracer uptake. Expand
The central Siberian origin for native American Y chromosomes.
TLDR
This study suggests a predominantly central Siberian origin for Native American paternal lineages for those who could have migrated to the Americas during the Upper Pleistocene. Expand
THE EFFECT OF MARKET ECONOMIES ON THE WELL-BEING OF INDIGENOUS PEOPLES AND ON THEIR USE OF RENEWABLE NATURAL RESOURCES
AbstractAssessing the effects of markets on the well-being of indigenous peoples and their conservation of natural resources matters to identify public policies to improve well-being and enhanceExpand
An ecomorphological model of the initial hominid dispersal from Africa.
TLDR
Two independent datasets provide a means of quantifying aspects of the dispersal of early Homo and suggest that rapid rates of dispersal appear to have been promoted by changes in foraging strategy and body size in H. erectus facilitated byChanges in ecosystem structure during the Plio-Pleistocene. Expand
Physical growth and nutritional status of Tsimane' Amerindian children of lowland Bolivia.
TLDR
Comparative analyses indicate that high levels of statural growth stunting are common among indigenous populations throughout lowland South America, and this problem appears to be largely attributable to poor dietary quality (diets low in key micronutrients) and high disease loads. Expand
Metabolic costs and evolutionary implications of human brain development
TLDR
The finding that human brain glucose demands peak during childhood, and evidence that brain metabolism and body growth rate covary inversely across development, support the hypothesis that the high costs of human brain development require compensatory slowing of body growth rates. Expand
