Article Abstract:
Three ways are suggested in which dehydroepiandrosterone sulfate (DHEAS) might play a role in human brain maturation, in order to understand the evolutionary origin of adrenarche, the prepubertal onset of adrenal production of DHEAS, in human life history. Comparison with the African apes suggests that the timing of adrenarche in chimpanzees might be similar to that in humans, while DHEAS is suggested to be a physiological mechanism influencing increased brain development, extended life span and decreased sexual dimorphism.

Article Abstract:
Saliva samples and anthropometrics measures were compared among nomadic and settled Ariaal pastoralists of northern Kenya, to determine if testosterone is negatively related to acute or chronic nutritional status among men is a subsistence society. Results suggest that salivary T is related to acute nutritional status among males in an energetically stressed subsistence population, in accordance with life history theories of somatic allocation.

Article Abstract:
An anthropometric data from Turkana pastoral nomads of Northern Kenya was collected to determine whether age related changes in body composition among males from energetically limited population were similar to Western population. The results indicate that age related patterns of fat-free mass in Turkana men were similar to Western population, but the age related patterns of adiposity differ.
