Tout au long de la préhistoire, les humains ont occupé le bassin de l’Escaut, dans le nord de la Belgique, bien que peu de restes humains y aient été retrouvés en comparaison au bassin de la Meuse, riche en grottes contenant des vestiges de diverses phases préhistoriques. La mauvaise conservation dans la zone septentrionale est due à l’acidité du sol, à la décalcification et à la sécheresse, qui dégradent les os. Jusqu’à récemment, peu d’efforts …
Limited human mobility during the Neolithic period in the Meuse and Mons basin in Belgium
While the introduction of the Neolithic way of life in central Belgium around 5300 BCE is well-documented, the provenance and mobility patterns of Middle to Final Neolithic groups in southern Belgium (Wallonia) remain unclear. This work presents the first multi-element isotopic (strontium, 87 Sr/ 86 Sr; oxygen, δ 18 O; carbon, δ 13 C) data from prehistoric human dental enamel from the region. The study includes a total of 29 individuals, coming f…

Evidence of lead poisoning and the co-occurrence of metabolic disease in Archaic/Early Classical (6th–5th century BCE) Laurion, Greece
Lead is one of the most toxic heavy metals and environmental pollutants on earth capable of adversely affecting every organ in the human body, with harmful short- and long-term effects. In the Laurion region of southeastern Attica, Greece, the extraction of silver-rich lead ores has been practiced since prehistoric times. This area was heavily mined during the late Archaic and Classical periods significantly contributing to Athens wealth and sove…
Neolithic mortuary behaviour at La Faucille Cave, Meuse Basin (Belgium)
The mortuary cave La Faucille is located in Sclayn, in the valley of the Fond des Vaux, a small tributary of the Meuse River (Andenne, prov. of Namur, BE). It was discovered in 1999, and after an initial survey it was excavated from 2015 onwards. The excavations yielded over 3000 identifiable human remains which were found both on the terrace and inside the cave. Also, a small but significant number of archaeological objects were recovered. A ser…

Nonmetric population‐specific sex estimation based on the skull using logistic regression for Flemish samples
There are very few sex estimation methods specifically designed for or tested on Belgian skulls. The currently used methods for European populations have been developed using North American collections where individuals are categorized as White and/or having European ancestry. These frequently show discordance between the pelvic sex and cranial sex estimations highlighting the need for population specific methods. To fill this gap in our knowledg…
Factors influencing cranial variation between prehistoric Japanese forager populations
Understanding the factors shaping human crania has long been a goal of biological anthropology, and climate, diet, and population history are three of the most well-established influences. The effects of these factors are, however, rarely compared within a single, variable population, limiting interpretations of their relative contribution to craniofacial form. Jomon prehistoric foragers inhabited Japan throughout its climatic and ecological rang…

Neolithic track sites from Formby Point, England
Formby Point, England is a well-documented exposure site in which marine erosion has regularly exposed Neolithic human trackways along the coastline since the 1980s. We report here the discovery of an additional 17 trackways and 61 isolated tracks (181 human footprints in total) discovered during four field seasons of natural site exposure at four localities in the Formby Point region, recorded in 2016–2018. This adds substantially to the existin…

Locomotion, posture, and the foramen magnum in primates
The position (FMP) and orientation (FMO) of the foramen magnum have been used as proxies for locomotion and posture in extant and extinct primates. Several indices have been designed to quantify FMP and FMO but their application has led to conflicting results. Here, we test six widely used indices and two approaches (univariate and multivariate) for their capability to discriminate between postural and locomotor types in extant primates and fossi…
Sex differences in the patterning of age‐related bone loss in the human hallucal metatarsal in rural and urban populations
OBJECTIVES: Age-degenerative features of the metatarsals are poorly known despite the importance of metatarsal bone properties for investigating mobility patterns. We assessed the role of habitual activity in shaping the patterning and magnitude of sexual dimorphism in age-related bone loss in the hallucal metatarsal. MATERIALS AND METHODS: Cross-sections were extracted at midshaft from micro-computed tomography scan models of individuals from me…
The morphological affinity of the Early Pleistocene footprints from Happisburgh, England, with other footprints of Pliocene, Pleistocene, and Holocene age
Non-invasive methods
Hominin fossilised trackways are commonly used to reconstruct locomotory behaviour and to characterise track-maker biometrics. They are the most direct representation of hominin locomotion available, yet the fossil sites are susceptible to extreme cases of erosion and weathering, often resulting in the destruction of the fossil beds, as was the case at two prehistoric footprint sites: Formby Point and Happisburgh, UK. Footprints can also be found…
The functional significance of dental and mandibular reduction in Homo
The reduction in dental size and mandibular robusticity is regarded as a major trend in human evolution, traditionally considered the result of the peculiar extra-oral food processing skills of Homo. The use of stone tools and fire would have allowed our ancestors to chew softer food in smaller bite size, thus relaxing the selective pressures to keep a large dentition and a robust lower jaw. This perspective assumes that differences in dental siz…

Prehistory of the British Isles
It is now recognised that Britain has not always been geographically isolated from Europe and, for most of the last one million years, formed an extension of the northwest European landmass. During most of this time, Britain was accessible to migrating humans and animals, although climatic conditions varied greatly from Mediterranean-like through to glaciations and extreme cold, making Britain a difficult place to settle for any length of time. T…

Neuromandibular integration in humans and chimpanzees
OBJECTIVES: Although the evolution of the hominin masticatory apparatus has been linked to diet and food processing, the physical connection between neurocranium and lower jaw suggests a role of encephalization in the trend of dental and mandibular reduction. Here, the hypothesis that tooth size and mandibular robusticity are influenced by morphological changes in the neurocranium was tested. MATERIALS AND METHODS: Three-dimensional landmarks, al…
Severe Plane-Form Enamel Hypoplasia in a Dentition from Roman Britain
Enamel defects can provide insight into the life histories of past individuals and populations, in-cluding information on a wide range of disturbances during childhood. This study investigates a particularly severe case of plane-form enamel hypoplasia from a Roman site in Gloucester, UK. Dentine protrudes above the occlusal enamel of upper central incisors, both upper canines, the lower left canine, lower right central incisor, and all four first…

Behavioral inferences from the high levels of dental chipping in Homo naledi
OBJECTIVES: A variety of mechanical processes can result in antemortem dental chipping. In this study, chipping data in the teeth of Homo naledi are compared with those of other pertinent dental samples to give insight into their etiology. MATERIALS AND METHODS: Permanent teeth with complete crowns evidencing occlusal wear were examined macroscopically. The location, number, and severity of fractures were recorded and compared to those found in s…

Technical note
Here we describe and evaluate a new method for quantifying long bone curvature using geometric morphometric and semi‐landmark analysis of the human femur. The technique is compared with traditional ways of measuring subtense and point of maximum curvature using either coordinate calipers or projection onto graph paper. Of the traditional methods the graph paper method is more reliable than using coordinate calipers. Measurement error is consisten…
Body mass and stature estimation based on the first metatarsal in humans
Archaeological assemblages often lack the complete long bones needed to estimate stature and body mass. The most accurate estimates of body mass and stature are produced using femoral head diameter and femur length. Foot bones including the first metatarsal preserve relatively well in a range of archaeological contexts. In this article we present regression equations using the first metatarsal to estimate femoral head diameter, femoral length, an…

Earliest evidence for caries and exploitation of starchy plant foods in Pleistocene hunter-gatherers from Morocco
Significance We present early evidence linking a high prevalence of caries to a reliance on highly cariogenic wild plant foods in Pleistocene hunter-gatherers from North Africa. This evidence predates other high caries populations and the first signs of food production by several thousand years. We infer that increased reliance on wild plants rich in fermentable carbohydrates caused an early shift toward a disease-associated oral microbiota. Syst…

N eanderthals, Biosocial Models of
Neanderthals lived successfully in Europe and western Asia during the Middle Paleolithic period. Through the study of biological variables, it has been possible to shed light on the social life of Neanderthals. They led strenuous lives that involved hunting large game and gathering plant foods in order to meet the high energetic demands of life in their ever‐changing cold climate. Neanderthals lived in small bands of between ten and twenty adults…
