Short‐ and Long‐Term Impact of Exogenous Hormones on Thermoregulation in Women
Women have stronger legs and other side‐effects of human body proportions
Average differences between the sexes are one type of evidence that humans are not geometrically similar, but often times the differences between limb proportions and mass distributions are separated from the biomechanical outcomes of such differences. Here differences in body composition between the sexes are considered within the context of the importance of whole-body center of mass. Whole body center of mass is important for how people mainta…
Beyond sex, gender, and other dilemmas: Human pelvic morphology from an integrative context
Recent research on the pelvis has clarified the flexibility of pelvic bones to manage nearly infinite possibilities in terms of selection and drift, while still maintaining excellent bipedalism. Despite this work, and the studies outlining the diversity of pelvic morphology across the hominin lineage, conversations continue to be stymied by distractions related to purported trade‐offs that the different functions the pelvis must either allow for …
Women carry for less: Body Size, Pelvis Width, Loading Position and Energetics
The energetic cost of walking varies with mass and speed; however, the metabolic cost of carrying loads has not consistently increased proportionally to the mass carried. The cost of carrying mass, and the speed at which human walkers carry this mass, has been shown to vary with load position and load description (e.g. child vs. groceries). Additionally, the preponderance of women carriers around the world, and the tendency for certain kinds of p…
Dehydration and persistence hunting in Homo erectus
The Evolutionary Biology of the Human Pelvis: An Integrative Approach
This book provides a synthetic overview of all evidence concerning the evolution of the morphology of the human pelvis, including comparative anatomy, clinical and experimental studies, and quantitative evolutionary models. By integrating these lines of research, this is the first book to bring all sources of evidence together to develop a coherent statement about the current state of the art in understanding pelvic evolution. Second, and related…
People choose to run at their optimal speed
Objectives The purpose of this article is to test whether people choose to behave in a manner that reduces the amount of energy they use to travel a given distance. While this has been shown consistently for walking, it has never been tested with human running. Materials and Methods We collected energetic data and lower limb anthropometrics on nine men running at six different running speeds. We collected on all six speeds on 3 different days and…
Reproductive costs for everyone: How female loads impact human mobility strategies
Size and Shape: Morphology's Impact on Human Speed and Mobility
While human sexual dimorphism is generally expected to be the result of differential reproductive strategies, it has the potential to create differences in the energetics of locomotion and the speed at which each morph travels, particularly since people have been shown to choose walking speeds around their metabolic optimum. Here, people of varying sizes walked around a track at four self-selected speeds while their metabolic rate was collected, …
Energetics, Locomotion, and Female Reproduction: Implications for Human Evolution
In our reconstructions of human evolution, a few key questions consistently rise to the surface. These questions tend to revolve around how the morphology of previous hominin species would have allowed them to gain access to resources during key life-history events, particularly gestation and lactation. Here the data surrounding the interactions between these key issues are assessed, making particular notes of recent advances in the fields of ene…
Electromyography activity across gait and incline: The impact of muscular activity on human morphology
The study of human evolution depends upon a fair assessment of the ability of hominin individuals to gain access to necessary resources. We expect that the morphology of extant and extinct populations represents a successful locomotory system that allowed individuals to move across the environment gaining access to food, water, and mates while still maintaining excess energy to allocate to reproduction. Our assessment of locomotor morphology must…
Optimal running speed and the evolution of hominin hunting strategies
Digital cementum luminance analysis (DCLA): A Tool for the Analysis of Climatic and Seasonal Signals in Dental Cementum
Cementum banding patterns have been used by archaeozoologists and wildlife managers for a number of decades to assess the season and age at death of mammalian populations. However, the observation and measurement of the nature of cementum banding, especially that of the final band, has proved to be difficult except under conditions of excellent preservation and advanced microscopy. The research presented here details a method for extracting lumin…
Digital Cementum Luminance Analysis and the Haua Fteah Hominins: How Seasonality and Season of Use Changed Through Time
The importance of environmental seasonality and the seasonal cycling of resources to human populations make studies of human responses to seasonality useful to test hypotheses about short‐ and long‐term changes in human behaviour. This paper utilizes digital dental cementum luminance analysis in order to better understand patterns of the seasons of death of Ammotragus lervia at Haua Fteah, Cyrenaica, and to test whether long‐term climatic changes…
Infant carrying: The role of increased locomotory costs in early tool development
Among the costs of reproduction, carrying one's infant incurs one of the greatest drains on maternal energy, simply because of the added mass alone. Because of the dearth of archaeological evidence, however, how early bipeds dealt with the additional cost of having to carry infants who were less able to support their body weight against gravity is not particularly well understood. This article presents evidence on the caloric drain of carrying an…
