Harm Avoidance and Mobility During Middle Childhood and Adolescence among Hadza Foragers
Cultural Change Reduces Gender Differences in Mobility and Spatial Ability among Seminomadic Pastoralist-Forager Children in Northern Namibia
Gendered movement ecology and landscape use in Hadza hunter-gatherers
Understanding how gendered economic roles structure space use is critical to evolutionary models of foraging behaviour, social organization and cognition. Here, we examine hunter-gatherer spatial behaviour on a very large scale, using GPS devices worn by Hadza foragers to record 2,078 person-days of movement. Theory in movement ecology suggests that the density and mobility of targeted foods should predict spatial behaviour and that strong gender…
Risk And Uncertainty In Tribal And Peasant Economies
Spatial Organization and Habitat Use
This chapter considers the human use of space from the perspective of behavioral ecology. It presents three large questions: How can one obtain a reliable supply of food and other resources, when resources vary in time and space? Where should one settle? And how large an area should one use, and when does it pay to defend it against intruders? A more sensitive approach to the problem of scale in spatial patterning is through autocorrelation and s…
Why Go There? Evolution of Mobility and Spatial Cognition in Women and Men
Sex Differences in Mobility and Spatial Cognition
Mobility and Navigation among the Yucatec Maya
Sex differences in range size and navigation are widely reported, with males traveling farther than females, being less spatially anxious, and in many studies navigating more effectively. One explanation holds that these differences are the result of sexual selection, with larger ranges conferring mating benefits on males, while another explanation focuses on greater parenting costs that large ranges impose on reproductive-aged females. We evalua…

Evolutionary Perspectives on Human Aggression
Waist-to-Hip Ratio across Cultures
A gynoid pattern of fat distribution, with small waist and large hips (low waist-to-hip ratio, or WHR) holds significant fitness benefits for women: women with a low WHR of about 0.7 are more fecund, are less prone to chronic disease, and (in most cultures) are considered more attractive. Why, then, do nearly all women have a WHR higher than this putative optimum? Is the marked variation in this trait adaptive? This paper first documents the conu…
Hormones and competitive aggression in women
This study used diaries of competitive interactions to explore the relationship between hormones and competitive aggression in women. Thirty women completed approximately 10 diary entries each. In each entry, the women described a recent competitive interaction they had engaged in and noted whether it was expressed aggressively or through other tactics. Each woman received a score for the fraction of her competitive interactions that were express…
Ethnic Diversity and Its Environmental Determinants
This article documents, and seeks to explain, the geographical patterning in ethnic group distributions. Some areas, chiefly equatorial regions and areas of high habitat diversity, are crowded with a large number of named groups. Elsewhere, people over a large area consider themselves members of a single group. Using three new codes for the Standard Cross-Cultural Sample (ethnic diversity, habitat diversity, and rainfall variation), I show that r…

Adaptiveness of food learning and food aversions in children
This paper uses an evolutionary perspective to explain features of food learning in human children. Data from Western parents indicate that (1) children are least picky about foods when they are between one and two years of age, (2) vegetables are frequently refused by children, and (3) children have a tendency to eat foods one at a time rather than mixed together. Adaptive explanations for these patterns are suggested, together with supporting e…

Territoriality Among Human Foragers
Cost-benefit models derived from evolutionary ecology have led to the general expectation that territoriality will be found where resources are most abundant and predictable. Literature sources for four Bushman groups, however, indicate that the most territorial of these groups are found where resources are sparsest and most variable. This paper has as its aim the extension of the animal models of territoriality to make them more widely applicabl…

Technological Change and Child Behavior among the !Kung
How does change in one part of a social system affect other parts? This is the central question that must be answered in order to understand the process through which culture changes. This paper is about a small piece of the problem. It investigates how changes in subsistence economy affect child behavior and the relations between parents and children among !Kung Bushmen of Western Botswana. We will show that the adoption of a sedentary life styl…

Competition between foragers and food-producers on the Botletli River, Botswana
Opening ParagraphThe immigration of food-producing groups into areas occupied by hunters and gatherers must have been a common occurrence in prehistory. How were the hunter-gatherers affected by this? I describe here two groups of Kalahari Basarwa ('Bushmen'), one living along the flood plain of the lower Botletli river, the other occupying the savanna a short distance away from the river. These two groups differed in subsistence and social organ…

Trade and Its Origins on the Botletli River, Botswana
This paper discusses the causes of trade and evaluates the roles played by habitat diversity, mobility, and competition. Ethnographic and ethnohistorical evidence from the Botletli River, Botswana, is used to evaluate some general arguments. The Botletli trade is shown to be based on locational advantages, due to the habitat diversity of the region, and on other comparative advantages arising from differential access to important resources. These…

Anthropological Applications of Optimal Foraging Theory
Recent applications of models of optimal foraging behavior to human foraging economies are summarized and evaluated. These models predict patterns of prey choice, habitat use, time allocation, settlement pattern, and foraging group size that will maximize some objective currency (such as the net rate of energy capture while foraging) under the constraints of resource characteristics and forager capabilities pertaining to a particular situation. I…
