W poszukiwaniu Piastów

Abstract

The origin of the Piast dynasty is a matter of lively discussions and disputes. At least a few controversial hypotheses exist, but their credibility is difficult to assess due to the scarcity of written as well as material sources, especially from the time of Polish state formation. Life sciences, however, can support history and archeology. Application of genetic tests, used earlier mainly in forensic laboratories, enabled identification of the remains of King Richard III, the Romanov dynasty members and Nicolaus Copernicus. Contemporary DNA studies, based on next generation DNA sequencing, outreach the narrow area of known markers such as mitochondrial DNA (mtDNA) and selected regions of Y chromosome. Although ancient DNA (aDNA), extracted from remains, is usually highly degraded and contaminated with genetic material of microorganisms, there are methods which allow for the analysis of such material and retrieval of information about origin, kinship and some phenotypic features of an individual. Genetic studies of the Piast dynasty, a subject of our research project, have to deal with numerous difficulties. In or der to gain access to bone samples, we need to meet a number of formal requirements. Moreover, despite the existence of available abundant documentation on the Piast burials, the actual situation is not always consistent with the written sources. Our first experiences show how difficult it is to localize the remains, identify them and extract DNA of sufficient quality.

The Early Mediaeval Slav-German border (Limes Sorabicus) in the light of research into Y-chromosome polymorphism in contemporary and historical German populations

“…There is also no direct link with ethnicity (this being a matter for the cultural environment to shape). Despite that, in line with conditioning of various different kinds, given haplogroups (and the subclades thereof) are not distributed at random through different human populations, but are in fact variants characteristic for ethnic origins, to the extent that a person's origins may be predicted by reference to them (Balanovsky et al, 2008;Krawczak et al, 2008;Rębała et al, 2012;Juras, 2012;Handschuh et al, 2016;Watson, Berry, & Davies, 2018).…”
