Objectives: The aims of this research are to explore the diet, mobility, social organization, and environmental exploitation patterns of early Mediterranean farmers, particularly the role of marine and plant resources in these foodways. In addition, this work strives to document possible gendered patterns of behavior linked to the neolithization of this ecologically rich area. To achieve this, a set of multiproxy analyses (isotopic analyses, dental calculus, microremains analysis, ancient DNA) were performed on an exceptional deposit (n = 61) of human remains from the Les Bréguières site (France), dating to the transition of the sixth to the fifth millennium BCE. Materials and Methods: The samples used in this study were excavated from the Les Bréguières site (Mougins, Alpes‐Maritimes, France), located along the southeastern Mediterranean coastline of France. Stable isotope analyses (C, N) on bone collagen (17 coxal bones, 35 craniofacial elements) were performed as a means to infer protein intake during tissue development. Sulfur isotope ratios were used as indicators of geographical and environmental points of origin. The study of ancient dental calculus helped document the consumption of plants. Strontium isotope analysis on tooth enamel (n = 56) was conducted to infer human provenance and territorial mobility. Finally, ancient DNA analysis was performed to study maternal versus paternal diversity within this Neolithic group (n = 30). Results: Stable isotope ratios for human bones range from −20.3 to −18.1‰ for C, from 8.9 to 11.1‰ for N and from 6.4 to 15‰ for S. Domestic animal data range from −22.0 to −20.2‰ for C, from 4.1 to 6.9‰ for N, and from 10.2 to 12.5‰ for S. Human enamel 87Sr/86Sr range from 0.7081 to 0.7102, slightly wider than the animal range (between 0.7087 and 0.7096). Starch and phytolith microremains were recovered as well as other types of remains (e.g., hairs, diatoms, fungal spores). Starch grains include Triticeae type and phytolith includes dicotyledons and monocot types as panicoid grasses. Mitochondrial DNA characterized eight different maternal lineages: H1, H3, HV (5.26%), J (10.53%), J1, K, T (5.2%), and U5 (10.53%) but no sample yielded reproducible Y chromosome SNPs, preventing paternal lineage characterization. Discussion: Carbon and nitrogen stable isotope ratios indicate a consumption of protein by humans mainly focused on terrestrial animals and possible exploitation of marine resources for one male and one undetermined adult. Sulfur stable isotope ratios allowed distinguishing groups with different geographical origins, including two females possibly more exposed to the sea spray effect. While strontium isotope data do not indicate different origins for the individuals, mitochondrial lineage diversity from petrous bone DNA suggests the burial includes genetically differentiated groups or a group practicing patrilocality. Moreover, the diversity of plant microremains recorded in dental calculus provide the first evidence that the groups of Les Bréguières consumed a wide breadth of plant foods (as cereals and wild taxa) that required access to diverse environments. This transdisciplinary research paves the way for new perspectives and highlights the relevance for novel research of contexts (whether recently discovered or in museum collections) excavated near shorelines, due to the richness of the biodiversity and the wide range of edible resources available.

The expansion of Neolithic stable isotope studies in France now allows distinct regional population-scale food patterns to be linked to both local environment influences and specific economic choices. Carbon and nitrogen isotope values of more than 500 humans and of animal samples also permit hypotheses on sex-biased human provenance. To advance population scale research, we here present the first study that draws together carbon (C), nitrogen (N), sulphur (S) and strontium (Sr), dental calculus, aDNA, and palaeoparasitology analysis to infer intra-population patterns of diet and provenance in a Middle Neolithic population from Le Vigneau 2 (human = 40; fauna = 12; 4720–4350 cal. BC) from north-western France. The data of the different studies, such as palaeoparasitology to detect diet and hygiene, CNS isotopes and dental calculus analysis to examine dietary staples, Sr and S isotopes to discriminate non-locals, and aDNA to detect maternal (mtDNA) versus paternal lineages (Y chromosome), were compared to anthropological information of sex and age. Collagen isotope data suggest a similar diet for all individuals except for one child. The provenance isotopic studies suggest no clear differences between sexes, suggesting both males and females used the territory in a similar pattern and had access to foods from the same environments.

Abstract: During recent decades, Neanderthal diet has been a major research topic in palaeoanthropology. This has been accelerated by the maturation of different techniques, which have produced a plethora of new information. However, this proliferation of data has led to confusing and contradictory results. Furthermore, most of the ecological dietary studies have been carried out on specimens drawn from different time periods and regions, almost exclusively those characterized by cold, open environmental conditions. Subsistence models based on these fragmentary data have been applied to Neanderthals living in a variety of different regions and environments, even though their dietary strategies may have been as variable as regions they inhabited. In this paper we integrate different dietary approaches (studies of the zooarchaeology, stable isotopes and plant remains) from the central and southeastern Mediterranean coast of Iberia in order to develop a broader and more complex picture of Neanderthal diet in different Mediterranean environmental conditions. Our results suggest that there may have been some minor dietary variation due to climatic or environmental differences, but that Neanderthal diet focussed on large terrestrial game, supplemented by plant foods when these were available.

Neanderthals are known primarily from their habitation of Western Eurasia, but they also populated large expanses of Northern Asia for thousands of years. Owing to a sparse archaeological record, relatively little is known about these eastern Neanderthal populations. Unlike in their western range, there are limited zooarchaeological and paleobotanical studies that inform us about the nature of their subsistence. Here, we perform a combined analysis of carbon and nitrogen stable isotopes on bone collagen and microbotanical remains in dental calculus to reconstruct the diet of eastern Neanderthals at Chagyrskaya Cave in the Altai Mountains of Southern Siberia, Russia. Stable isotopes identify one individual as possessing a high trophic level due to the hunting of large- and medium-sized ungulates, while the analysis of dental calculus also indicates the presence of plants in the diet of this individual and others from the site. These findings indicate eastern Neanderthals may have had broadly similar subsistence patterns to those elsewhere in their range. [ABSTRACT FROM AUTHOR]

Research increasingly suggests that natural and social environments shaped the Neolithic expansion of the farming niche into Europe. The Danube Gorges, on account of its position between the Mediterranean and more temperate regions and the presence of archaeological sites with continuous Mesolithic and Neolithic layers of occupation associated with vast burial grounds is ideal for studying the modality of Neolithization. Previous dietary stable isotope (carbon, nitrogen, and sulphur) studies in the Central Balkan area indicate that many Neolithic humans remained reliant on foraged aquatic resources in the Gorges. Until now, there is no unambiguous evidence of cereal consumption in this region. The possibility that the rich aquatic resources of the Danube river habitats within Central Balkans influenced diet and thus delayed uptake of Neolithic cultigens is unanswered. The extensive skeletal record from sites in the Danube Gorges (Central Balkans) with its long temporal sequence, provides the opportunity to reconstruct plant use during Mesolithic and the Neolithic. To assess when cereals and possibly cultivated plants spread to the region, we analysed the microbotanical remains (starch grains and phytoliths) entrapped in the dental calculus of 81 individuals dating from 9100 to 5500 cal BC, recovered from five sites in the Danube Gorges. This study marks the largest study of dental calculus from this period so far conducted. Added to this, we present new radiocarbon dates (n = 17), bone collagen stable isotope data (δ13C and δ15N; n = 5) and data on caries frequency. This dietary study identifies that the growing of crops commenced in the Early Neolithic circa 6000 cal BC and was brought by farming migrants of north-western Anatolian ancestry into the Danube Gorges. Despite bringing a Neolithic agro-pastoral subsistence practices and cultural novelties in the Gorges, these migrants and their descendants adopted some of the local dietary and cultural traditions, suggesting a mosaic pattern of Neolithization. The resulting data provides a better understanding of the tempo and spread of cereal agriculture practices and the role of cereals in the diet of Danube Gorges inhabitants. • The largest study of microbotanical remains in prehistoric dental calculus. • Cultivated cereals were present in the Danube Gorges region from circa 6000 cal BC. • Dental and stable isotope data corroborate the consumption of new plants foods. • The local social and ecological environment impacted on the development of farming niches.
