Tras las huellas del pasado
El estudio de las huellas fósiles de homininos ha cobrado un papel importante en la investigación sobre el comportamiento y la locomoción en el pasado. Estas impresiones preservadas a lo largo del tiempo permiten aproximarse de forma excepcional a la interacción entre los individuos y su entorno, en momentos concretos del Pleistoceno. El objetivo de este trabajo es ofrecer una revisión crítica y sistematizada de la literatura científica reciente …
Validation of predictive equations to estimate resting metabolic rate of females and males across different activity levels
Objectives Using equations to predict resting metabolic rate (RMR) has yielded different degrees of validity, particularly when sex and different physical activity levels were considered. Therefore, the purpose of the present study was to determine the validity of several different predictive equations to estimate RMR in female and male adults with varying physical activity levels. Method We measured the RMR of 50 adults (26 females and 24 males)…
Far from the walking pace. Ecological and evolutionary consequences of the suboptimal locomotion speeds in non‐adult humans
Introduction Locomotion activities are part of most human daily tasks and are the basis for subsistence activities, particularly for hunter–gatherers. Therefore, differences in speed walking‐related variables may have an effect, not only on the mobility of the group, but also on its composition. Some anthropometric parameters related to body length could affect walking speed‐related variables and contribute to different human behaviors. However, …
Evaluating the human capacity of carrying loads without costs
To be or not to be a lithic tool
Let's Play at Digging
Extractive foraging tasks, such as digging, are broadly practiced among hunter-gatherer populations in different ecological conditions. Despite tuber-gathering tasks being widely practiced by children and adolescents, little research has focused on the physical traits associated with digging ability. Here, we assess how age and energetic expenditure affect the performance of this extractive task. Using an experimental approach, the energetic cost…
Sex‐specific differences in somatic investment and strategies of physical activity among Portuguese schoolchildren
OBJECTIVES: Physical activity (PA) is required for healthy growth, development, and maturation and plays an important role in the prevention of overweight and obesity in childhood and adolescence. Sex-differences in PA levels are well documented, with boys spending more time in PA, especially in moderate-to-vigorous activities. Following the Life History Theory, our aim is to study if PA affects the fat tissues increases during childhood and juve…
Know-how, or How Knapping Experience Can Affect a Prehistoric Lithic Workshop
In situ archaeological assemblages are scarce. Most artefacts are affected by post-depositional processes, which complicate the identification of human factors involved in the formation of lithic workshops, such as hand laterality, knapping positions, and knapping expertise. In this regard, experimental archaeology can reproduce past processes to test present hypotheses. In this study, experimental knapping processes were carried out to examine h…
Gathering Is Not Only for Girls
Locomotor Economy and Foraging Ecology in Hominins
The ratio of net energy gained over time expended while foraging (Net Rate of Energy Gain or NREG) or the ratio of net energy gained over energy expended (Foraging Energy Efficiency or FEE) are commonly used measures of foraging success in modern and ancient hunter-gatherers. This work addresses how and to what extent somatic proportions may influence energy gain during foraging trips. An experimental study was carried out on a sample of 46 subje…
No sex differences in the economy of load‐carriage
OBJECTIVES: Load transport activities are of vital importance to current foragers for daily subsistence tasks; thus, it has been suggested that these practices have transformed physical and behavioral characteristics through human evolution. Together with the procurement targets and strategies, the transportation of resources acquired while foraging is strongly influenced by the sex of the foragers. In hunter-gatherer societies, women, despite th…
Does optimal foraging theory explain the behavior of the oldest human cannibals
Cannibalism is an old and widespread human practice; however, the causes and meaning of consuming other humans are still hotly debated. Several explanations are possible for cannibalistic behavior, ranging from social and cultural motivations to purely nutritional causes. In this study, we analyze the oldest known case of cannibalism to date in the framework of the Optimal Foraging Theory (OFT). The fossil assemblage from the TD6.2 unit of the Gr…
Energetic cost of walking in fossil hominins
OBJECTIVE: Many biomechanical studies consistently show that a broader pelvis increases the reaction forces and bending moments across the femoral shaft, increasing the energetic costs of unloaded locomotion. However, a biomechanical model does not provide the real amount of metabolic energy expended in walking. The aim of this study is to test the influence of pelvis breadth on locomotion cost and to evaluate the locomotion efficiency of extinct…
