This article provides an estimation of how frequently, and from whom, children aged 0–11 years ( N s between 9 24) receive one‐on‐one verbal input among Tsimane forager‐horticulturalists lowland Bolivia. Analyses systematic daytime behavioral observations reveal < 1 min per daylight hour is spent talking to younger than 4 age, which times less estimates for others present at the same time place. Adults provide a majority 0–3 age but not afterward. When integrated with previous work, these...
The rise in blood pressure with age is a major risk factor for cardiovascular and renal disease, stroke, type 2 diabetes mellitus. Age-related increases have been observed almost every population, except among hunter-gatherers, farmers, pastoralists. Here we tested age-related Tsimane forager-farmers. We also test whether lifestyle changes associated modernization lead to higher greater rate of increase pressure. measured longitudinally on 2248 adults ≥20 years (n=6468 observations over 8...
The intensifying pace of research based on cross-cultural studies in the social sciences necessitates a discussion unique challenges multi-sited research. Given an increasing demand for scientists to expand their data collection beyond WEIRD (Western, educated, industrialized, rich and democratic) populations, there is urgent need transdisciplinary conversations logistical, scientific ethical considerations inherent this type scholarship. As group engaged psychology anthropology, we hope...
Parasitic worms influence human fecundity infect 2 billion people globally. Mostly, such infections are symptomless and individual worm burdens low. Blackwell et al. monitored the of Tsimane women in Bolivia. These have on average 10 children their lifetimes. However, if they had successive hookworm infections, lifetime births dropped to 7. Surprisingly, were chronically infested with roundworm, as many 12 children. effects may relate balance immune responses that different induce, rather...
Amazonian populations are exposed to diverse parasites and pathogens, including protozoal, bacterial, fungal helminthic infections. Yet much knowledge of the immune system is based on industrialised where these infections relatively rare.This study examines distributions age-related differences in 22 measures function for Bolivian forager-horticulturalists US European populations.Subjects were 6338 Tsimane aged 0-90 years. Blood samples collected between 2004-2014 analysed 5-part blood...
The apolipoprotein E4 (E4) allele is present worldwide, despite its associations with higher risk of cardiovascular morbidity, accelerated cognitive decline during aging, and Alzheimer's disease (AD). especially prevalent in some tropical regions a high parasite burden. Equatorial populations also face potential dual burden prevalence combined parasitic infections that can reduce performance. We examined the interactions E4, burden, performance traditional, nonindustrialized population...
The suite of derived human traits, including enlarged brains, elevated fertility rates, and long developmental periods life spans, imposes extraordinarily high energetic costs relative to other great apes. How do subsistence strategies accommodate our expanded energy budgets? We found that apes, hunter-gatherers farmers spend more but less time on subsistence, acquire substantially per hour, achieve similar efficiencies. These findings revise understanding evolution by indicating humans...
This paper presents a new two‐sex learning‐ and skills‐based theory for the evolution of human menopause. The proposes that role knowledge, skill acquisition, transfers in determining economic productivity resource distribution is distinctive feature traditional ecology responsible also male reproductive cessation post‐reproductive investment descendants fundamental characteristic humans living foraging simple horticultural economies. We present evidence relevant to theory. data show whereas...
Cognitive performance is characterized by at least two distinct life course trajectories. Many cognitive abilities (e.g., "effortful processing" abilities, including fluid reasoning and processing speed) improve throughout early adolescence start declining in adulthood, whereas other "crystallized" like vocabulary breadth) adult life, remaining robust even late ages. Although schooling may impact "reserve," it has been argued that these age patterns of are human universals. Here we examine...
Abstract Objectives Resting metabolic rate (RMR) reflects energetic costs of homeostasis and accounts for 60 to 75% total energy expenditure (TEE). Lean mass physical activity account much RMR variability, but the impact prolonged immune activation from infection on human is unclear in naturalistic settings. We evaluate effects mass‐corrected among Bolivian forager‐horticulturalists, assess whether declines more slowly with age than hygienic sedentary populations, as might be expected if...
In post-industrial settings, apolipoprotein E4 ( APOE4 ) is associated with increased cardiovascular and neurological disease risk. However, the majority of human evolutionary history occurred in environments higher pathogenic diversity low We hypothesize that high-pathogen energy-limited contexts, allele confers benefits by reducing innate inflammation when uninfected, while maintaining lipid levels buffer costs immune activation during infection. Among Tsimane forager-farmers Bolivia N =...
In high-income countries, one's relative socio-economic position and economic inequality may affect health well-being, arguably via psychosocial stress. We tested this in a small-scale subsistence society, the Tsimane, by associating household wealth (n = 871) community-level 40, Gini 0.15-0.53) with range of psychological variables, stressors, outcomes (depressive symptoms [n 670], social conflicts 401], non-social problems 398], support 399], cortisol 811], body mass index 9,926], blood...
While it is commonly assumed that farmers have higher, and foragers lower, fertility compared to populations practicing other forms of subsistence, robust supportive evidence lacking. We tested whether subsistence activities-incorporating market integration-are associated with in 10,250 women from 27 small-scale societies found considerable variation fertility. This did not align group-level typologies. Societies labeled as "farmers" higher than others, while "foragers" lower However, at the...
Abstract Objectives: We develop and test a conceptual model of factors influencing women's ideal family size (IFS) in natural fertility population, the Tsimane Bolivia. The posits affects socioecology, reproductive history, maternal condition, men's IFS. three hypotheses for why women may exceed their IFS despite experiencing socioeconomic development: ( H 1 ) limited autonomy; 2 improved condition; 3 low returns on investments embodied capital. Methods: Women's histories prospective data...
