Menopause Averted a Midlife Energetic Crisis With Help From Older Dependent Children and Parents
The Meanings and Dividends of Man the Hunter
The phrase Man the Hunter is associated with disparate meanings across communities of scholars, journalists, and the public, which has led to unnecessary scientific disagreement and popular misunderstanding. In this paper, we ask: what does Man the Hunter mean? We distinguish three historical meanings of Man the Hunter. First, in the early-to-mid 20th century, popular writers propagated ideas of human evolution that focused on hunting, men, aggre…

The Multi-Capital Leadership Theory
The Natural History of Child Signals of Need in Utila, Honduras
Female foragers sometimes hunt, yet gendered divisions of labor are real
The Multi-Capital Leadership Theory
Human leadership and followership take many forms, shaped by the social, economic, political, and cultural contexts of our groups and societies. Underlying this complexity, we argue, are key elements of human social psychology regarding social comparison and the resolution of coordination and collective action problems. More specifically, the Multi-Capital Leadership (MCL) theory posits that leader emergence and effectiveness depend on perception…
The impact of gossip, reputation, and context on resource transfers among Aka hunter-gatherers, Ngandu horticulturalists, and MTurkers
In need-based sharing, sharing is more important than need
Cooperative resource sharing is widespread across cultures, and it was likely critical during much of human evolutionary history for pooling risk. Need-based sharing specifically pools risk by following two cooperative rules: help others when asked, and only request help when in need. In a two-part study, we first expanded an agent-based model of need-based sharing partnerships, adding two types of defection and varying partnership sizes. We show…
Response to
Bargaining and interdependence
The anthropology of Pacific cultures spotlights social conflict as a proximate cause of suicide. Ethnographic accounts suggest that suicidal behaviors are high-cost conflict-resolution strategies. We investigate parent-child conflicts and the strategies adolescents and young adults use to resolve them, using concepts from human behavioral ecology to interpret results from in-depth, semi-structured interviews with 58 Chon Chuuk participants. One s…
Depression and suicidality as evolved credible signals of need in social conflicts
Religion
The Biological Roots of Music and Dance
All Models Are Wrong, and Some Are Religious
Many cognitive and evolutionary theories of religion argue that supernatural explanations are byproducts of our cognitive adaptations. An influential argument states that our supernatural explanations result from a tendency to generate anthropomorphic explanations, and that this tendency is a byproduct of an error management strategy because agents tend to be associated with especially high fitness costs. We propose instead that anthropomorphic a…

Mental health is biological health
The germ theory of disease and the attendant public health initiatives, including sanitation, vaccination, and antibiotic treatment, led to dramatic increases in global life expectancy. As the prevalence of infectious disease declines, mental disorders are emerging as major contributors to the global burden of disease. Scientists understand little about the etiology of mental disorders, however, and many of the most popular psychopharmacological …

The impact of information about tobacco-related reproductive vs. general health risks on South Indian women's tobacco use decisions
Origins of music in credible signaling
How did music evolve? We show that prevailing views on the evolution of music - that music is a byproduct of other evolved faculties, that music evolved for social bonding, and that music evolved to signal mate quality - are incomplete or wrong. We argue instead that music evolved as a credible signal in at least two contexts: coalitional interactions and infant care. We suggest that basic features of music, including melody and rhythm, result fr…
Music and dance as a coalition signaling system
Psychological adaptations for assessing gossip veracity
Living with Kin in Lowland Horticultural Societies
Postmarital residence patterns in traditional human societies figure prominently in models of hominid social evolution with arguments for patrilocal human bands similar in structure to female-dispersal systems in other African apes. However, considerable flexibility in hunter-gatherer cultures has led to their characterization as primarily multilocal. Horticulturalists are associated with larger, more sedentary social groups with more political i…
Do human parents face a quantity‐quality tradeoff
A number of evolutionary theories of human life history assume a quantity‐quality tradeoff for offspring production: parents with fewer offspring can have higher biological fitness than those with more. Direct evidence for such a tradeoff, however, is mixed. We tested this assumption in a community of Ecuadorian Shuar hunter‐horticulturalists, using child anthropometry as a proxy for fitness. We measured the impact of household consumer/producer …
Cooperative Breeding and Adolescent Siblings
In humans, alloparents are usually thought to be grandmothers and adolescent girls. Although many studies have examined the influence of grandmothers on child outcomes, fewer have explored the effect of adolescents on such outcomes. We tested the hypothesis that in a community of Ecuadorian Shuar horticulturists, adolescent girls would have a positive influence on the growth and development of younger siblings. We measured height, weight, and ski…

Perinatal Sadness among Shuar Women
Psychiatry faces an internal contradiction in that it regards mild sadness and low mood as normal emotions, yet when these emotions are directed toward a new infant, it regards them as abnormal. We apply parental investment theory, a widely used framework from evolutionary biology, to maternal perinatal emotions, arguing that negative emotions directed toward a new infant could serve an important evolved function. If so, then under some definitio…
New Genealogy
Genealogy has been a pillar of anthropological research since the earliest ethnographic fieldwork. A turn toward demographically and quantitatively oriented kinship studies in the 1960s highlighted the need for more systematic genealogical methods. New computer-assisted, iterative field methods were developed in response. These methods can dramatically improve data quality and quantity and are remarkably flexible. Here, the authors outline an ite…

Household composition and the infant fecal microbiome
OBJECTIVES: Establishment and development of the infant gastrointestinal microbiome (GIM) varies cross-culturally and is thought to be influenced by factors such as gestational age, birth mode, diet, and antibiotic exposure. However, there is little data as to how the composition of infants' households may play a role, particularly from a cross-cultural perspective. Here, we examined relationships between infant fecal microbiome (IFM) diversity/c…

The East Indian Diaspora in Costa Rica
Anthropologists have long been interested in the survival of Indian cultural traits in the New World. In this article, we present results of an ongoing project with a Costa Rican community that descends from East Indian indentured servants. We focus on the group's marriage patterns and how these patterns might have helped keep the community as a cohesive ethnic group. We investigate the group's level of inbreeding by computing the inbreeding coef…

The Functions of Postpartum Depression
Parental Investment and Child Health in a Yanomamö Village Suffering Short-Term Food Stress
The 1998 El Niño significantly reduced garden productivity in the Upper Orinoco region in Venezuela. Consequently, parents were forced to allocate food carefully to their children. Nutrition data collected from village children combined with genealogical data allowed the determination of which children suffered most, and whether the patterns of food distribution accorded with predictions from parental investment theory. For boys, three social var…

Did Neanderthals and other early humans sing? Seeking the biological roots of music in the territorial advertisements of primates, lions, hyenas, and wolves
Group defence of territories is found in many gregarious mammalian carnivores, including lions, canids, and hyenas. In these taxa, group members often mark territory boundaries and direct aggressive behaviour towards alien conspecifics found within the territory (Boydston et al., 2001). Middle Pleistocene hominids such as Neanderthals occupied an ecological niche similar to such large carnivores (Stiner, 2002), and so could be expected to share w…

A test of three hypotheses of pica and amylophagy among pregnant women in Tamil Nadu, India
OBJECTIVES: Pica has been studied in India and elsewhere for more than 100 years, yet no compelling and empirically well-supported explanation for it has emerged. Amylophagy, sometimes considered a type of pica and sometimes studied separately, is less frequently investigated and also lacks a convincing explanation. This study used a biocultural approach to test three hypotheses of pica and amylophagy: protection, hunger/nutrition, and psychologi…

High prevalence of cannabis use among Aka foragers of the Congo Basin and its possible relationship to helminthiasis
OBJECTIVES: Little is known about cannabis use in hunter-gatherers. Therefore, we investigated cannabis use in the Aka, a population of foragers of the Congo Basin. Because cannabis contains anthelminthic compounds, and the Aka have a high prevalence of helminthiasis, we also tested the hypothesis that cannabis use might be an unconscious form of self-medication against helminths. METHODS: We collected self- and peer-reports of cannabis use from …

Social networks, cooperative breeding, and the human milk microbiome
OBJECTIVES: We present the first available data on the human milk microbiome (HMM) from small-scale societies (hunter-gatherers and horticulturalists in the Central African Republic [CAR]) and explore relationships among subsistence type and seasonality on HMM diversity and composition. Additionally, as humans are cooperative breeders and, throughout our evolutionary history and today, we rear offspring within social networks, we examine associat…
DHEAS patterning across childhood in three sub‐Saharan populations
OBJECTIVES: Hormones have many roles in human ontogeny, including the timing of life history 'switch points' across development. Limited hormonal data exist from non-Western children, leaving a significant gap in our understanding of the diversity of life history patterning. This cross-sectional study examines dehydroepiandrosterone sulfate (DHEAS) production in relation to age, sex, ethnicity, and cortisol concentrations, as well as average age …
