Evolution of primate vocal repertoires: Vocal systems as embodied capital for mediating within-group conflict
Life history traits constrain investments in costly neural and somatic embodied capital, potentially shaping the evolution of primate vocal communication systems. This study integrates life history theory with the social complexity hypothesis to test a sequential pathway from longevity to social dynamics to vocal repertoire size, using updated vocal repertoire data for McComb & Semple’s (2005) set of 42 non-human primate species, alongside measur…
More than the sum of its sexes: Functional constraints, embodied capital, and age-structured labor in human forager economies
"The paper's rough consensus attributes the SDoL to differential variance in food returns across male- and female-typical foraging domains, sourcing this primarily to Bird and Codding (2015) and Kelly's (2013) reframe of the classic 'hunting vs. gathering' axis as 'risky vs. non-risky foraging.' Indeed, the data show that males more often pursue large game and honey, resources that yield higher caloric returns but with high unpredictability, inju…
Better-than-chance prediction of cooperative behaviour from first and second impressions
Could cooperation among strangers be facilitated by adaptations that use sparse information to accurately predict cooperative behaviour? We hypothesise that predictions are influenced by beliefs, descriptions, appearance and behavioural history available for first and second impressions. We also hypothesise that predictions improve when more information is available. We conducted a two-part study. First, we recorded thin-slice videos of universit…
Cultural transmission vectors of essential knowledge and skills among Tsimane forager-farmers
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 …
Stepfamilies, adoption and other forms of the family in hunter-gatherers

Who helps Tsimane youth
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…

Trust in humans and robots: Economically similar but emotionally different
Marriage dynamics in old Lower California: Ecological Constraints and Reproductive Value in an Arid Peninsular Frontier
It is commonly expected that natural selection will favor earlier reproduction, yet ecological constraints can force people to delay marriage. Furthermore, humans demonstrate sex-specific preferences in marriage partners - with grooms normally a few years older than their brides; however, the age at which individuals marry can influence the spousal age gap. We investigate factors influencing age at first marriage and age difference at marriage us…

Information transmission and the oral tradition: Evidence of a late-life service niche for Tsimane Amerindians

Conflicted emotions following trust-based interaction
Skill ontogeny among Tsimane forager‐horticulturalists
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…
Functional Disability and Social Conflict Increase Risk of Depression in Older Adulthood Among Bolivian Forager-Farmers
Tsimane depression is associated with disability, reduced subsistence productivity, and interpersonal conflict, all of which can disrupt resource flows. Depression appears to be a response to conditions regularly experienced over human history, and not simply a by-product of modernity

Domestication Alone Does Not Lead to Inequality: Intergenerational Wealth Transmission among Horticulturalists
We present empirical measures of wealth inequality and its intergenerational transmission among four horticulturalist populations. Wealth is construed broadly as embodied somatic and neural capital, including body size, fertility and cultural knowledge, material capital such as land and household wealth, and relational capital in the form of coalitional support and field labor. Wealth inequality is moderate for most forms of wealth, and intergene…
