In the Rhône Valley's Middle Neolithic gathering site of Saint-Paul-Trois-Châteaux (France), the positioning of two females within a structure aligned with the solstices is atypical. Their placement (back and prone) under the overhang of a silo in front of a third in a central position suggests a ritualized form of homicidal ligature strangulation. The first occurrence dates back to the Mesolithic, and it is from the Early Neolithic of Central Europe that the practice expands, becoming a sacrificial rite associated with an agricultural context in the Middle Neolithic.

Article Synopsis
  • The study analyzes 317 ancient genomes from Mesolithic and Neolithic periods across northern and western Eurasia to understand human migration impacts during the Holocene.* -
  • Findings show a significant genetic divide between eastern and western populations, with the west experiencing major gene replacement due to the introduction of farming, while the east maintained its hunter-gatherer ancestry longer.* -
  • The Yamnaya culture, which emerged around 5,000 BP, played a crucial role in spreading ancestry across western Eurasia, leading to significant genetic changes in European populations.*

Archaeological research shows that the dispersal of the Neolithic took a more complex turn when reaching western Europe, painting a contrasted picture of interactions between autochthonous hunter-gatherers (HGs) and incoming farmers. In order to clarify the mode, the intensity, and the regional variability of biological exchanges implied in these processes, we report new palaeogenomic data from Occitanie, a key region in Southern France. Genomic data from 28 individuals originating from six sites spanning from c.

Epipaleolithic hunter-gatherers from the Near East introduced wild boars (Sus scrofa) to Cyprus, with the Early Pre-Pottery Neolithic (PPN) settlers hunting the wild descendants of these boars. However, the geographic origin of the Cypriot boar and how they were integrated into the earliest forms of pig husbandry remain unsolved. Here, we present data on 11,000 to 9000 cal.

Article Synopsis
  • The transition from the Late Neolithic to the Bronze Age in western Europe involved significant changes in populations and societies, primarily due to the genomic contributions of pastoralists from the Pontic-Caspian steppes.
  • This process was marked by the interaction between declining hunter-gatherers and expanding farmers, leading to diverse genetic backgrounds in populations across regions, particularly noted through ancient genomic data from Britain, Ireland, and Germany, though less so in France.
  • In a study focusing on ancient genomes from France, researchers found considerable genetic diversity, evidence of hunter-gatherer ancestry, and the influence of steppe migrations, highlighting a complex and varied history of human interactions in the region.

Today, sheep farmers in the Western Mediterranean de-season their ewes to achieve autumnal births. This strategy contrasts sharply with spring lambing further north, and provides benefits in terms of out-of-season availability of animal products. These competences are closely linked to specific sheep physiology and favorable Western Mediterranean climatic conditions.

Genomic studies conducted on ancient individuals across Europe have revealed how migrations have contributed to its present genetic landscape, but the territory of present-day France has yet to be connected to the broader European picture. We generated a large dataset comprising the complete mitochondrial genomes, Y-chromosome markers, and genotypes of a number of nuclear loci of interest of 243 individuals sampled across present-day France over a period spanning 7,000 y, complemented with a partially overlapping dataset of 58 low-coverage genomes. This panel provides a high-resolution transect of the dynamics of maternal and paternal lineages in France as well as of autosomal genotypes.

Farming economy was first introduced to the coastal areas of Southern France by Impressa groups (ca. 5850-5650 cal BC), originating from Italy, and subsequently spread to the hinterland by Cardial/Epicardial communities (ca. 5400-4500 cal BC).

In the absence of any direct evidence, the relative importance of meat and dairy productions to Neolithic prehistoric Mediterranean communities has been extensively debated. Here, we combine lipid residue analysis of ceramic vessels with osteo-archaeological age-at-death analysis from 82 northern Mediterranean and Near Eastern sites dating from the seventh to fifth millennia BC to address this question. The findings show variable intensities in dairy and nondairy activities in the Mediterranean region with the slaughter profiles of domesticated ruminants mirroring the results of the organic residue analyses.

Article Synopsis
  • Honeybee populations face threats from pesticides, diseases, and other stressors, highlighting their vital role in agriculture and the historical relationship between humans and bees dating back to ancient Egypt and even the Stone Age.
  • Evidence suggests that humans have been harvesting bee products, particularly beeswax, since prehistoric times, and its chemical composition allows for recognizing these products in archaeological contexts.
  • Research indicates that Neolithic farmers across Europe, the Near East, and North Africa continuously exploited bee products from at least the seventh millennium cal BC, suggesting an essential cultural and technological role for honeybees in early agricultural societies.

Early Neolithic sedentary villagers started cultivating wild cereals in the Near East 11,500 y ago [Pre-Pottery Neolithic A (PPNA)]. Recent discoveries indicated that Cyprus was frequented by Late PPNA people, but the earliest evidence until now for both the use of cereals and Neolithic villages on the island dates to 10,400 y ago. Here we present the recent archaeological excavation at Klimonas, which demonstrates that established villagers were living on Cyprus between 11,100 and 10,600 y ago.

The impact of the Neolithic dispersal on the western European populations is subject to continuing debate. To trace and date genetic lineages potentially brought during this transition and so understand the origin of the gene pool of current populations, we studied DNA extracted from human remains excavated in a Spanish funeral cave dating from the beginning of the fifth millennium B.C.

The Neolithic is a key period in the history of the European settlement. Although archaeological and present-day genetic data suggest several hypotheses regarding the human migration patterns at this period, validation of these hypotheses with the use of ancient genetic data has been limited. In this context, we studied DNA extracted from 53 individuals buried in a necropolis used by a French local community 5,000 y ago.

The beginnings of pig domestication in Southwest Asia are controversial. In some areas, it seems to have occurred abruptly ca. 10,500 years ago, whereas in nearby locations, it appears to have resulted from a long period of management of wild boar starting at the end of the Late Pleistocene.
