Determinants of infant carrying behavior in rural Papua New Guinea
OBJECTIVES: The determinants of variability in infant carrying within and across societies is an understudied area within parental investment research. Carrying has positive and negative consequences as it may protect the infant from predators and pathogens but is energetically costly for caregivers. Moreover, carrying may delay independent locomotor development and exposure to antigens necessary for immunological competence. The purpose of this …
Prenatal stress exposure and early childhood BMI: Exploring associations in a New Zealand context
OBJECTIVES: The primary purpose of this study was to (i) examine associations between prenatal objective vulnerability and subjective stress, and (ii) investigate the relationships between prenatal vulnerability and subjective stress and early childhood BMI at 24- and 54- months of age after controlling for covariates. METHODS: The Growing Up in New Zealand (GUiNZ) longitudinal study provided information on 5839 pregnant women and their children …

Breastfeeding structure as a test of parental investment theory in Papua New Guinea
Evolutionary parental investment theory predicts that parents invest preferentially in offspring best able to translate investments into fitness payoffs. It has also been proposed that where the reproductive prospects of offspring are directly correlated with parental investment and variance in fertility is higher for males than females, parents in better condition should bias investment toward males while those in poorer condition should bias in…
“Economic man” in cross-cultural perspective: Behavioral experiments in 15 small-scale societies
Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we un…

Somatic versus reproductive energy allocation in Papua New Guinea: Life history theory and public health policy
A fundamental evolutionary problem faced by organisms is how to allocate energy to somatic and reproductive functions in ways that optimize fitness. Given that energy is limited in all environments, energy allocation necessarily involves physiological tradeoffs between such factors as growth and reproduction, reproduction and condition, and current reproduction and future survival. Ultimately, the "decisions" that are made about energy allocation…
Two decade trends in birth weight and early childhood growth in Papua New Guinea
At present, little is known about patterns of early growth and development in foraging and small-scale horticultural populations. Moreover, still less is known about secular changes in growth in these populations. Data collected in 1967, 1976, and 1989 are presented for birth weight and subsequent growth to 5 years among Au forager-horticulturalists of Papua New Guinea. Despite the launching of health campaigns over the last two decades aimed at …
Clines and clusters versus “Race: ” A test in ancient Egypt and the case of a death on the Nile
The biological affinities of the ancient Egyptians were tested against their neighbors and selected prehistoric groups as well as against samples representing the major geographic population clusters of the world. Two dozen craniofacial measurements were taken on each individual used. The raw measurements were converted into C scores and used to produce Euclidean distance dendrograms. The measurements were principally of adaptively trivial traits…

Fertility‐related changes in maternal body composition among the au of Papua New Guinea
Evolutionary theory predicts that organisms make trade‐offs between their somatic and reproductive energy budgets. Thus every round of reproduction should result in a concomitant decline in the parents' total energy reserves. Among humans this prediction was corroborated more than 25 years ago when fertility‐related nutritional depletion was reported among mothers in the Highlands of New Guinea (Jelliffe and Maddocks, 1964). More recently, howeve…
Dimensions of face in Asia in the perspective of geography and prehistory
Data from 24 craniofacial dimensions were compiled for samples representing all the human populations of the world. These were converted into C scores and used to construct Euclidean Distance dendrograms. The populations of the world are best depicted as 8 major regional clusters representing: Africa, Amerind, Asia‐Mainland, Australo‐Melanesia, Eskimo‐Siberia, Europe, India, and Jömon‐Pacific. The mainland Asian cluster divided into northern and …
Standards of arm muscle by stature for the assessment of nutritional status of children
This study is based on a sample of 9,134 children ranging in age from 2 to 17 years from which the excessively lean and fat children by skinfold thickness were excluded. This sample was derived from the combined data sets of the first and second National Health and Nutrition Examination Surveys (NHANES I and II) of 1971–1974 and 1976–1980. Means and percentiles of upper arm muscle area were calculated for 3 cm increments in stature from 84 to 184…
