  • Exceptionally low mortality despite widespread Covid-19 infection among Indigenous Tsimane and Moseten of Bolivia

    Open AccessLucia Inchauste, Xavier de Lamballerie et al.ARTICLESocial Science & Medicine2026

  • Cultural transmission vectors of essential knowledge and skills among Tsimane forager-farmers

    Open AccessE Schniter, H Kaplan et al.ARTICLEEvolution and Human Behavior2023

    Humans transmit cultural information to others in a variety of ways that can affect productivity, cultural success, and ultimately fitness. Not all potential transmitters are expected to be equally preferred by learners or equally willing to influence their culture acquisition. Across socioeconomic opportunities and ages in the human life course, costs and benefits to both learners and potential transmitters are expected to vary, affecting rates …

  • Who helps Tsimane youth

    E Schniter, Daniel K Cummings et al.ARTICLEHunter Gatherer Research2023Citada por: 2Referencias: 75

    We examine various forms of helping behaviour among Tsimane Amerindians of Bolivia, focusing on the provision of shelter, childcare, food, sickcare, cultural influence and traditional story knowledge. Kin selection theory traditionally explains nepotistic nurturing of youth by closely related kin. However, less attention has been given to understanding the help provided by individuals without close genetic relatedness. To explain who provides var…

  • High resting metabolic rate among Amazonian forager‐horticulturalists experiencing high pathogen burden

    Open AccessM Gurven, Michael D Gurven et al.ARTICLEAmerican Journal of Physical…2016Citada por: 15Referencias: 72

    OBJECTIVES: Resting metabolic rate (RMR) reflects energetic costs of homeostasis and accounts for 60 to 75% of total energy expenditure (TEE). Lean mass and physical activity account for much RMR variability, but the impact of prolonged immune activation from infection on human RMR is unclear in naturalistic settings. We evaluate the effects of infection on mass-corrected RMR among Bolivian forager-horticulturalists, and assess whether RMR declin…

  • Conflict or congruence? Maternal and infant-centric factors associated with shorter exclusive breastfeeding durations among the Tsimane

  • Skill ontogeny among Tsimane forager‐horticulturalists

    Open AccessE Schniter, M Gurven et al.ARTICLEAmerican Journal of Physical…2015Citada por: 16Referencias: 76

    OBJECTIVES: We investigate whether age profiles of Tsimane forager-horticulturalists' reported skill development are consistent with predictions derived from life history theory about the timing of productivity and reproduction. Previous studies of forager skill development have often focused on a few abilities (e.g. hunting), and neglected the broad range of skills and services typical of forager economies (e.g. childcare, craft production, musi…

  • Fatty acid composition in the mature milk of Bolivian forager‐horticulturalists

    Open AccessMélanie Martins, Melanie A Martin et al.ARTICLEMaternal and Child Nutrition2012

    Breast milk fatty acid (FA) composition varies greatly among individual women, including in percentages of the long-chain polyunsaturated FAs (LCPUFA) 20:4n-6 (arachidonic acid, AA) and 22:6n-3 (docosahexaenoic acid, DHA), which are important for infant neurological development. It has been suggested that owing to wide variation in milk LCPUFA and low DHA in Western diets, standards of milk FA composition should be derived from populations consum…

  • The emergence of humans

    Open AccessH Kaplan, Hillard S Kaplan et al.ARTICLEProceedings of the National…2002

    Two striking differences between humans and our closest living relatives, chimpanzees and gorillas, are the size of our brains (larger by a factor of three or four) and our life span (longer by a factor of about two). Our thesis is that these two distinctive features of humans are products of coevolutionary selection. The large human brain is an investment with initial costs and later rewards, which coevolved with increased energy allocations to …
