In the attempt to understand culture and social behavior of prehistoric populations, findings of personal ornaments are of particular interest. Personal ornaments in their formal expressions (marine shells and snails, river snails, animal teeth, modified animal bones etc.) not only point to an universal idea of decoration and aesthetic sensibility, but may also reveal contact zones and communic...

Archaeological finds of personal ornaments reveal not only behavioural patterns of the society they belong to, but also their forms of manifestations indicate connections, contacts and communication paths, exchange networks and movements of prehistoric populations. This paper advances the current knowledge regarding ornamental traditions in Eastern Adriatic area during Late Upper Palaeolithic a...

Both lead and cadmium exposures derive from natural sources and also from industrialisation and certain habits, such as cigarette smoking in the case of cadmium. Some of these sources only affect human beings. The aim of this study was to determine the levels of lead and cadmium in bone samples of 16 prehispanic inhabitants of Gran Canaria, 24 prehispanic domestic animals (sheep, goat and pigs)...

The study of prehistoric demography draws inevitably on evidence both imperfect and incomplete, yet is essential for a satisfactory understanding of past communities. It is particularly valuable in addressing controversial questions such as the nature of early farming communities in western Europe, in the period between the adoption of domestic plants and animals and the establishment, centurie...

The human population has grown significantly since the onset of the Holocene about 12,000 y ago. Despite decades of research, the factors determining prehistoric population growth remain uncertain. Here, we examine measurements of the rate of growth of the prehistoric human population based on statistical analysis of the radiocarbon record. We find that, during most of the Holocene, human popul...

Research into human-environment interaction in California prehistory often focuses on either the internal dynamics of adaptive decisions or the external impacts of environmental change. While both processes were surely driving prehistoric variability, integrating these approaches is not altogether straightforward. Here we outline an inclusive approach examining the exploitation of acorn habitat...

The experts of animal locomotion well know the characteristics of quadruped walking since the pioneering work of Eadweard Muybridge in the 1880s. Most of the quadrupeds advance their legs in the same lateral sequence when walking, and only the timing of their supporting feet differ more or less. How did this scientific knowledge influence the correctness of quadruped walking depictions in the f...

The Uto-Aztecan premolar (UAP) is a dental polymorphism characterized by an exaggerated distobuccal rotation of the paracone in combination with the presence of a fossa at the intersection of the distal occlusal ridge and distal marginal ridge of upper first premolars. This trait is important because, unlike other dental variants, it has been found exclusively in Native American populations. Ho...

Cinnabar is a natural mercury sulfide (HgS) mineral of volcanic or hydrothermal origin that is found worldwide. It has been mined prehistorically and historically in China, Japan, Europe, and the Americas to extract metallic mercury (Hg(0)) for use in metallurgy, as a medicinal, a preservative, and as a red pigment for body paint and ceramics. Processing cinnabar via combustion releases Hg(0) v...

Tuberculosis is a prehistoric American human disease. This paper reviews the literature and discusses hypotheses for origins and epidemiological patterns of prehistoric tuberculosis. From the last decades, 24 papers about prehistoric tuberculosis were published and 133 cases were reviewed. In South America most are isolated case studies, contrary to North America where more skeletal series were...
