Unity and diversity in the Late Iron Age of Northern France: contributions from palaeogenetics

Palaeogenetic analysis was conducted on the Second Iron Age human communities from Urville-Nacqueville and Gurgy with the aim both of documenting their genetic affinities with earlier or contemporary groups and of discussing the significance of biological relations between individuals in how these societies were organized. At both regional and local levels, the emphasis is therefore placed on systematically exploring the biological (genetic) and cultural diversities of communities.

Ten millennia of hepatitis B virus evolution

Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene. After the European Neolithic transition, Mesolithic HBV strains were replaced by a lineage likely disseminated by early farmers that prevailed throughout western Eurasia for ~4000 years, declining around the end of the 2nd…

The role of fire within Neolithic collective burials: Spatial analyses of cremains from the site of La Truie Pendue, France

International audience; The use of collective graves is one of the main features of the western European Late Neolithic. A single gravesite received the successive deposition of dozens or sometimes hundreds of individuals. While cremations or even full-fired inhumation layers are often found within these funerary deposits, the actual role of fire is still poorly understood. Recently discovered within the important archaeological complex of Passy (Yonne, France), the burned collective grave of La Truie-Pendue provides an outstanding case study to examine the use of fire within Neolithic funerary rites. In this study, we develop a new contextual approach to bone alterations in order to recons…

Using Y-chromosome capture enrichment to resolve haplogroup H2 shows new evidence for a two-path Neolithic expansion to Western Europe

Uniparentally-inherited markers on mitochondrial DNA (mtDNA) and the non-recombining regions of the Y chromosome (NRY), have been used for the past 30 years to investigate the history of humans from a maternal and paternal perspective. Researchers have preferred mtDNA due to its abundance in the cells, and comparatively high substitution rate. Conversely, the NRY is less susceptible to back mutations and saturation, and is potentially more informative than mtDNA owing to its longer sequence length. However, due to comparatively poor NRY coverage via shotgun sequencing, and the relatively low and biased representation of Y-chromosome variants on capture assays such as the 1240 k, ancient DNA…

A multi-isotope analysis of Neolithic human groups in the Yonne valley, Northern France: insights into dietary patterns and social structure

With the arrival of the Neolithic to Europe, new ways of life and new subsistence strategies emerged. In the Paris Basin (northern France), the appearance of some monumental funerary structures during the Middle Neolithic highlights in particular the increasing complexity of the social organisation. At the same time, several sites, such as open-air cemeteries, do not display any evidence of such arrangement. In the southeast of this area, the two primary routes of neolithisation meet. Several funerary parameters attest to the diverse influence received from other surrounding cultures. In order to assess potential differences in diet, and therefore on purported social distinctions at the int…

Observations préliminaires à l'étude des remplissages des tombes du Néolithique moyen I de Gurgy "Les Noisats" (Yonne)

This paper presents results of experimental digging and filling of a pit in gravel context. That experimentation is the first step of an integrated analysis about sedimentary dynamic in neolithic burials from Gurgy « Les Noisats » (Yonne, France).

Artisanat, commerce et nécropole. Un port de La Tène D1 à Urville-Nacqueville

International audience; Nous présentons dans cet article les premiers résultats d’une fouille programmée en cours sur la plage d’Urville-Nacqueville. Initiées en 2009, ces recherches ont permis de mettre au jour les vestiges d’un centre artisanal et commercial dont le dynamisme et la prospérité sont exprimés par de nombreux marqueurs dont l’association est rarement documentée en dehors des sanctuaires ou des nécropoles (amphores républicaines, statères, parures en matériaux importés). La découverte et l’étude également en cours d’une importante nécropole située à quelques centaines de mètres de ce secteur autorisent à interpréter le site dans son ensemble comme une agglomération portuaire. …
