As a result, this year is likely to be another challenging one, our panellists agreed. Nature 476, 214219 (2011). 7, 10326 (2016).
For present-day variation, PC1 and PC2 broadly reflect geography, forming a V-shaped pattern from Scandinavians via individuals from northern Germany and the Netherlands towards those from Britain and Ireland. 2, e190 (2006). To aid interpretation of our genetic data, we also radiocarbon-dated 57 samples selected on the basis of ancestry composition, burial assemblage and preservation. Eur. USA 110, 22232227 (2013). We calculated the PWMR94 in all pairs of individuals from our pseudo-haploid dataset to double check for potential duplicate individuals and to determine first-degree, second-degree and third-degree relatives. For example, historical sources going back to Bede (writing in the eight century) indicated Jutes as settlers in Kent. PLINK: a tool set for whole-genome association and population-based linkage analyses. Meyer, M. & Kircher, M. Illumina sequencing library preparation for highly multiplexed target capture and sequencing. Bioinformatics 29, 16821684 (2013). This shows that there is a significant difference within the treatment of individuals according to their ancestry, a finding very similar to those at early medieval cemeteries in Hungary and Italy with respect to northern versus southern European ancestry51.

However, we also note the strong genetic homogeneity among most analysed sites in the northern Netherlands, northern Germany and Denmark (Supplementary Note4), implying that, during the Early Middle Ages, the continental North Sea and adjacent western Baltic Sea area was a genetic continuum spanning most of the western North European plain without major geographical substructure (Supplementary Fig. This pattern is also visible in East Anglia specifically, where individuals with CNE ancestry more often have grave goods (P=0.014). 7, Supplementary Table 5.1 and Supplementary Fig. Each bar represents genome-wide mixture proportions for one individual. As a result, the individuals who we analysed from eastern England derived up to 76% of their ancestry from the continental North Sea zone, albeit with substantial regional variation and heterogeneity within sites. Although we cannot precisely date the order of those arrivals, at least substantial amounts of France IA-related ancestry seem to be absent in northern and eastern England during the Early Middle Ages and therefore must have arrived there subsequently.

The feasibility of ancient DNA analyses to inform on population history in Britain was first demonstrated with the report of genome-wide ancient DNA (aDNA) data26,37 from 20 individuals from the Iron Age to the Early Middle Ages, two studies that have provided unambiguous evidence for continental ancestry in early and middle Anglo-Saxon contexts.

After a successful return in 2021, with over 2300 attendees, 890+ companies in attendance and 168 exhibitors, Breakbulk is expecting an even bigger turnout this year. Of note, in contrast to the preceding Bronze and Iron Age individuals from Britain and Ireland, the majority of the early medieval samples from England (England EMA) plot together with the ancient individuals from the continental North Sea area along with the present-day CNEs. Both the lack of genetic evidence for male sex bias, and the correlation between ancestry and archaeological features, point to women being an important factor in this migration.

More recently, the first genome-wide study of present-day British people concluded that immigrant continental northern European ancestry makes up less than 50% of the present-day southeastern English gene pool36. Sci. Notably in southern England, namely, Eastry, Apple Down and Rookery Hill, several early medieval individuals already exhibit France IA-related ancestry, which probably results, at least in part, from localized mobility between the south of England and the Frankish areas of Europe during the Early Middle Ages (Extended Data Fig. Breakbulk Americas will. We used PMDtools87 (v0.50) to isolate sequences from each sample that had clear evidence of contamination (over 5% on the X chromosome or mitogenome) according to the post-mortem damage score (PMD score > 3, using only bases with phred-scaled quality of at least 30 to compute the score), and performed contamination estimation again. 1,113 (Archaeopress, 2003). Never miss a must-attend event again. 5 and Supplementary Fig. Samples sizes for present-day PoBI sampling regions are indicated in Supplementary Table 5.16. Am. These genetic patterns suggest that early medieval individuals from England have variable amounts of CNE ancestry. Overall, these patterns of genetic heterogeneity, from the transregional to the family level, are consistent with continuous interaction between the Iron Age-derived Romano-British population and migrants from the continent. Anderson, C. A. et al. Genetics 192, 10651093 (2012). 13 (ed. Google Scholar. 4, 1764 (2013). We note that a model involving southern or western European-like ancestry in England has been previously proposed36 on the basis of present-day samples, but we can now go further and delineate this third component more clearly against the CNE-like immigrant gene pool making up the majority of the early medieval individuals from England that we studied.
