Article
Full-text available
The sex profile estimation of pre-historic communities is often complicated by the commingled and scattered nature of skeletal assemblages. Demographic profiles are usually lacking and provide very truncated representations of these populations but proteomic analysis of sex-specific amelogenin peptides in tooth enamel brings new promise to these st...
Article
Full-text available
Comparison among archaeological samples, using frequencies of dental morphological traits, allows us to develop hypotheses about the genetic history of an area. More accurate than the measurement of skulls or extrapolations from modem gene frequencies, often more feasible and simpler than studies of ancient DNA, the study of dental traits should be...
Presentation
Dental analysis in commingled remains is challenging. This work explores the limitations and potentials of dental paleopathological analysis in an osteoarcheological sample from a Medieval-Modern ossuary exhumed in Miranda-do-Corvo (Coimbra, Portugal). The effect of differential preservation between in-situ and loose teeth was explored to interpret...

O presente estudo apresenta um caso de transmigração de um canino numa mandíbula proveniente de um ossário Medieval-Moderno (Miranda-do-Corvo, Coimbra). Identificou-se um canino esquerdo impactado na região dos incisivos, recorrendo-se à análise macroscópica e imagiologia. Este caso realça a importância da radiologia como ferramenta diagnóstica nos...

Anatomical variations of teeth are used to understand population interactions, migrations, and establish geographic or biological origins and affinities of ancient and recent human populations. As such, dental morphology is a good indicator of past population biological and cultural dynamics. Maxillary lateral incisor mesial bending, or "Etruscan U...

Ancient DNA research in the past decade has revealed that European population structure changed dramatically in the prehistoric period (14,000-3,000 years before present, YBP), reflecting the widespread introduction of Neolithic farmer and Bronze Age Steppe ancestries. However, little is known about how population structure changed in the historica...

The transitions from foraging to farming and later to pastoralism in Stone Age Eurasia (c. 11-3 thousand years before present, BP) represent some of the most dramatic lifestyle changes in human evolution. We sequenced 317 genomes of primarily Mesolithic and Neolithic individuals from across Eurasia combined with radiocarbon dates, stable isotope da...

Non‐masticatory dental lesions (e.g., notching, interproximal grooving, polished surfaces, lingual tilting, and dental trauma) may help evaluate the impact that dietary, individual, or social‐cultural habits had on ancient populations. Thus, this study aims to describe and discuss possible causes for dental wear and trauma recorded in 1206 commingl...

Dental pathology can provide information not only on the diet of past populations but also on populational biocultural differences. This study aims to interpret dental pathology of the individuals exhumed from a medieval-modern rural ossuary located next to Torre Sineira of Alto do Calvário (Miranda do Corvo) in terms of the biocultural conditions...

Como qualquer cápsula temporal, o conjunto recuperado da gruta do Medronhal abre uma janela sobre o passado, um passado mal conhecido, muito distante, nem sempre compreendido e praticamente omisso das referências da actualidade. Ao longo deste livro procurou-se realçar a extrema importância desses achados nas suas diferentes expressões e dimensões...

Significance Subsistence shifts from hunting and gathering to agriculture over the last 12,000 y have impacted human culture, biology, and health. Although past human health cannot be assessed directly, adult stature variation and skeletal indicators of nonspecific stress can serve as proxies for health during growth and development. By integrating...

Introduction Identified skeletal and skull collections are centrepiece for research in biological anthropology. However, until recently, the same relevance has not been placed on dental cast collections. This perspective evolved, mainly, with the research on population variation and human identification through dental characteristics. While dental...

Brucellosis is a zoonosis caused by bacteria of the genus Brucella. Clinical studies describe osteoarticular complications as one of the most frequent symptoms. Additionally, brucellosis is related to life-threatening complications during pregnancy for both mother and child. This case study aims to present and discuss the osteological lesions obser...

The recent discovery and archaeological excavation of two funerary structures located at Horta do Pinheiro 5 (south of Portugal) shed new light on the early times of the Southwestern Middle Bronze Age. These structures, a pit and a hypogeum, both associated with another pit, deepen our knowledge about the funerary rituals practiced at that time. Gr...

Background Hansen’s disease (leprosy), widespread in medieval Europe, is today mainly prevalent in tropical and subtropical regions with around 200,000 new cases reported annually. Despite its long history and appearance in historical records, its origins and past dissemination patterns are still widely unknown. Applying ancient DNA approaches to i...

Entheseal changes (ECs), that is the visible appearance at the attachment sites of tendons to bones, have been widely used to infer activity in bioarchaeology. The majority of recent research on ECs, testing methodological approaches and the impact of age and occupation, has focussed on male lives. The primary reason for this is the wider range of...

From around 2750 to 2500 BC, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 BC. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide...
