Dynamic changes in genomic and social structures in third millennium BCE central Europe.

Europe's prehistory oversaw dynamic and complex interactions of diverse societies, hitherto unexplored at detailed regional scales. Studying 271 human genomes dated ~4900 to 1600 BCE from the European heartland, Bohemia, we reveal unprecedented genetic changes and social processes. Major migrations preceded the arrival of "steppe" ancestry, and at ~2800 BCE, three genetically and culturally differentiated groups coexisted.

Facial skeleton asymmetry and its relationship to mastication in the Early Medieval period (Great Moravian Empire, Mikulčice, 9th-10th century).

Objectives: The aim of this study was to analyse the relationship of mastication and directional asymmetry (DA) of upper facial skeleton in Early Medieval sample from the Mikulčice settlement (Czech Republic).

Design: The settlement is divided into two burial areas of presumably different socioeconomic status: the castle and the sub-castle. The material consisted of 193 individuals (125 castle, 68 sub-castle).

The prevalence and distribution of dental caries in four early medieval non-adult populations of different socioeconomic status from Central Europe.

Objectives: The aim of the study was to map the dental health status in non-adult individuals and to verify whether and how the existence of caries in the non-adult age group is associated with the different socio-economic status of early medieval populations.

Material And Methods: We studied the dental remains from the acropolis of the Mikulčice settlement agglomeration, where members of the higher social classes were buried, and from the Mikulčice hinterland. Overall, we evaluated 2544 teeth/3714 alveoli of deciduous dentition and 1938 teeth/2128 alveoli of permanent dentition.

[Evaluation of the dental pathology in archaeological skeletal material: prevalence of dental caries since prehistory to modern age].

The evaluation of the dental health of past populations is an important part of the anthropological analysis of human skeletal remains uncovered during the archaeological excavations. The results provide the important information not only of the overall health of past populations, but also are reflective of the nutrition or the social status of our ancestors. We focused on the comparison of dental caries from prehistoric times to the present day.

The health status of the early medieval population of Greater Moravia in relations to social and economic structures.

The Greater Moravian Empire (9th-10th century AD) was the first early state formation of the Slavonic populations in Central Europe. The focus of this research is the comparative assessment of the health status of three cemeteries of different socio-economic status in the area surrounding the Mikulcice castle. We have compared about 850 skeletons from (1) the castle cemetery and (2) non-castle cemeteries in Mikulcice and (3) a cemetery from the poor village of Josefov located eight kilometres from Mikulcice.
