Coast–inland mobility and diet in the Danish Mesolithic and Neolithic: evidence from stable isotope values of humans and dogs

Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ¹³C values surprisingly similar to those seen in marine fish. We propose a model, based on δ¹³C and δ¹⁵N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.     

Modelling the effect of Mesolithic populations on the slowdown of the Neolithic transition

The expansion of the Neolithic transition in Europe took place gradually from the Near East across the whole continent. At Northern Europe, observations show a slowdown in the speed of the Neolithic front in comparison to other regions of the continent. It has been suggested that the presence of high population densities of hunter-gatherers at the North could have been the main cause for this slowdown. This proposal has recently been described by a mathematical model that takes into account: (i) the resistance opposed by the Mesolithic populations to the advance of Neolithic populations in their territory, and (ii) a limitation on the population growth dynamics due to the competition for space and resources. But these two effects are not equally responsible for the slowdown of the spread. Indeed, here we show that the limitation on the population growth dynamics seems to have been the main cause of the delay of the expansion of farming in Northern Europe.     

Early Neolithic diet and animal husbandry: stable isotope evidence from three Linearbandkeramik (LBK) sites in Central Germany

The first appearance of the Neolithic Linearbandkeramik (LBK) in Central Germany occurred during the 6th millennium BC. However, though LBK sites are abundant in the German loess areas, there are only a few studies that reconstruct the diet of these first farmers using biochemical methods. Here we present the largest study undertaken to date on LBK material using stable isotope analysis of carbon and nitrogen to reconstruct human diet and animal husbandry strategies. We analyzed the bone collagen of 97 human individuals and 45 associated animals from the sites of Derenburg, Halberstadt and Karsdorf in the Middle Elbe–Saale region of Central Germany. Mean adult human values are ?19.9 ± 0.4‰ for δ¹³C and 8.7 ± 0.8‰ for δ¹⁵N. The δ¹³C values are typical for terrestrial, temperate European regions, whereas the δ¹⁵N values fall within an expected range for farming societies with a mixed diet consisting of products from domestic animals and plants. The consumption of unfermented dairy products is unlikely as there is direct palaeogenetic evidence of lactose intolerance available for one of the sites. There are no clear indications for dietary differences in sex. Young children under three years of age are enriched in δ¹⁵N due to breastfeeding indicating that weaning likely occurred around the age of three years. The fauna exhibit mean δ¹³C values of ?20.9 ± 0.8‰ and mean δ¹⁵N values of 7.0 ± 0.9‰ respectively. Variation in the δ¹³C and δ¹⁵N in the domestic animals is probably caused by different livestock managements.     

Clearances and Clearings: Deforestation in Mesolithic/Neolithic Britain

Clearances, interpreted from pollen records during the Mesolithic and Neolithic of Europe, are generally ascribed to purposive deforestation which is compatible with the transition model, whereby early Neolithic economic strategies are a development of late Mesolithic intensification of wild plant food husbandry. This paper considers the role of natural processes in creating clearings and the role of inadvertent impact of human activity on forest processes, including woodland regeneration. The role of climate, wind-throw and lightning strikes in creating clearings and forest instability is emphasised and the evidence discussed from sites which may be interpreted as resulting from opportunistic human use of natural clearings. Unfortunately, regional pollen diagrams lack sufficient spatial resolution to detect the size of isolated clearings or establish the spatial variation in forest composition that was intimately related both to forest ecology and the effects of subtle human impacts. This may be the major reason for an apparent contradiction between pollen evidence of Neolithic impact and the archaeological record. Moreover, early Neolithic agricultural activity may have been concentrated in valley bottoms, which is undetectable in regional pollen diagrams. Alternative models need to be considered, which include culturally specific exploitation of the local environment, along with the inadvertent ecological repercussions of pre-agricultural and early-agricultural human activities in naturally dynamic woodlands.     

Relations of Mesolithic hunter-gatherers of Pomerania (Poland) with Neolithic cultures of central Europe

Abstract

The appearance of the first farming groups on the North European Plain was the turning point for the Mesolithic foragers who had inhabited that region for almost 7000 years. Interrelations between these two very different communities are fascinating for archaeologists interested in the northern European Stone Age. Research at D?bki in Poland provides elements for a discussion of the Neolithic transformation along the southern Baltic coast. Pottery from the regions inhabited by Danubian societies has been found in a hunting-gathering context (), a fact that sheds light on relations between local Late Mesolithic communities and early farmers. Imports from the Linear Pottery Culture, the Stroked Pottery Culture, the Lengyel Culture, and the Ertebølle Culture are found associated with Late Mesolithic layers, while pottery of the Bodrogkeresztúr Culture is related with the local Funnel Beaker settlement. This imported pottery reflects long lasting contacts between Mesolithic and those Neolithic communities that promoted the neolithization of the coastal region.     

Stable isotopes in human skeletons of Southern Ontario: reconstructing Palaeodiet

Most native plants of Ontario use the C₃ photosynthetic mechanism and therefore have relatively low ${}^{13}\text{C}{}^{12}\text{C}$ ratios; maize is a C₄ plant and is relatively enriched in ¹³C. The proportion of maize in the diet of a human can therefore be estimated from the ¹³C-content of collagen of fossil bone. We have used this method to follow the increase in consumption of maize in ancient native populations over the interval from AD 400 to 1650, and to quantify the amount of maize consumed. Maize consumption rose gradually to a maximum of 50% of the diet by AD 1400. These data agree with archaeologically derived data for this region, and with previous isotope studies in the northeastern U.S.A. In some of the latter, however, the maximum percentage of maize consumed has been overestimated because maize was assumed to have a δ¹³C value of ?12·5‰; our studies of archaeological specimens show the correct value to be closer to ?9‰. The introduction of beans into the native diet about AD 1100, should have caused a decrease in the ¹⁵N content of human bone collagen because legumes are deficient in this isotope, with respect to meat and fish. However, we observe no significant change in the ${}^{15}\text{N}{}^{14}$N ratio of human bone collagen over the period from 2300 BC to AD 1640. We conclude that meat and fish remained the main sources of protein even after the advent of agriculture into this region.     

Preliminary evidence for medieval Polish diet from carbon and nitrogen stable isotopes

In this pilot study, stable carbon and nitrogen isotopes from bone collagen and apatite of skeletons from the 11th and 12th century cemetery in Giecz, Poland are interpreted. Isotope values from a small number of fish and animal bones from the same archaeological site are also examined. The goal of this research is to provide preliminary evidence of diet for a group of medieval Polish peasants, with particular emphasis on sex-based differences in diet. Results of isotope analyses suggest diet of this early medieval population was omnivorous and terrestrial-based. Fish bones sampled exhibit low δ¹³C ratios, and in half of the cases are significantly enriched in ¹⁵N, indicating they are freshwater species. Human bones do not reflect these signatures, suggesting freshwater fish were not a significant source of dietary protein at Giecz. The ¹³C_coll from some human bones is enriched beyond what might be expected from an exclusively C₃ diet. Associated mammal bones do not exhibit similarly elevated δ¹³C_coll ratios, suggesting enrichment among humans is not due to consumption of animals foddered on C₄ plants. Two possible sources of ¹³C_coll enrichment are marine fish in diet and direct consumption of a C₄ plant, such as millet. The δ¹³C values obtained from bone apatite of a small subset of humans suggest that millet contributes to ¹³C_coll enrichment, although at least three individuals may have also consumed small amounts of marine fish. Sex-based differences in δ¹⁵N ratios indicate that men consumed relatively more animal products (meat or dairy) than did women. There is also a correlation between δ¹³C_coll and δ¹⁵N values in skeletons of men that is absent in women. These carbon and nitrogen isotope data are the first reported for any Polish population and contribute to a more complete picture of dietary adaptation and social organization in medieval Europe.     

Neolithic subsistence patterns in northern Borneo reconstructed with stable carbon isotopes of enamel

The Neolithic period in island Southeast Asia is characterized by various population movements, technological innovations, and the introduction/adoption of agricultural foodstuffs. Human subsistence trends during this period, however, are poorly understood. Broad spectrum foraging is generally assumed for prehistoric groups utilizing rain forest food resources but the degree to which cultigens were part of the dietary repertoire remains unclear. This paper explores human subsistence patterns at three penecontemporaneous Neolithic sites in Sarawak (East Malaysia) using stable isotope ratios of carbon and oxygen derived from tooth enamel apatite. The sites (Niah Cave, Lubang Angin, and Gua Sireh) differ in local ecology and cultural circumstance but all are situated in C₃-dominant lowland primary rain forest. Significant differences in δ¹³C values between sites likely reflect the canopy effect and variations in foraging pattern. Lower values at Lubang Angin suggest dependence upon closed forest foraging. Higher values at Neolithic Niah Cave and Gua Sireh suggest more open forest horticulture and subsistence, including some form of systematic food production, collection, and/or habitat modification.     

Late Mesolithic burials at Casa Corona (Villena,Spain): direct radiocarbon and palaeodietary evidence of the last forager populations in Eastern Iberia

Current knowledge about the Mesolithic–Neolithic transition in the Central and Western Mediterranean European regions is deeply limited by the paucity of Late Mesolithic human osteological data and the presence of chronological gaps covering several centuries between the last foragers and the first archaeological evidence of farming peoples. In this work, we present new data to fill these gaps. We provide direct AMS radiocarbon dating and carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the chronology and subsistence patterns of the last Mesolithic communities in the Central Mediterranean region of the Iberian Peninsula. Radiocarbon results date the human remains and funerary activity of the site to 6059–5849 cal BC, statistically different from other Late Mesolithic sites and the earliest Neolithic contexts, and bridging the 500 yrs chronological gap of the Mesolithic–Neolithic transition from the area. Isotopic evidence shows that diet was based on terrestrial resources despite the proximity to the site of lagoon and marine ecosystems. This and previous isotope studies from the region suggest a lower reliance upon marine resources than for Atlantic and Cantabrian sites, although intra-regional patterns of neighbouring Mesolithic populations exhibit both fully terrestrial diets and diets with significant amounts of aquatic resources in them. We hypothesize that in the Central Mediterranean region of Spain the Late Mesolithic dietary adaptations imposed structural limits on demographic growth of the last foragers and favoured rapid assimilation by the earliest Neolithic populations.     

Demography and ethnic continuity in the Tlailotlacan enclave of Teotihuacan: the evidence from stable oxygen isotopes

Mechanisms for the maintenance of Zapotec ethnicity in Tlailotlacan, an enclave of Teotihuacan, Mexico, are reconstructed using oxygen-isotope analyses of bone and enamel phosphate. The data indicate continual interaction among the enclave inhabitants, their Oaxacan homeland, and other diaspora colonies, with no dominant post-marital residence pattern. There is no apparent association between social status and place of origin, and individual agency is indicated by variable acceptance of Teotihuacan traditions. Striking patterns of movement include the sojourning of children in other regions and the relocation of breastfeeding women. These segments of the population would have played major roles in the social and political articulation of diaspora colonies. Foreign signatures in primary burials indicate that some immigrants died shortly after their arrival in Tlailotlacan. Data from secondary burials indicate the transportation of dead relatives or ancestors to Teotihuacan for burial. We conclude that the behaviour of immigrants in ancient and modern cities is analogous in many ways.     

Fossil dogs and wolves from Palaeolithic sites in Belgium,the Ukraine and Russia: osteometry,ancient DNA and stable isotopes

Using multivariate techniques, several skulls of fossil large canids from sites in Belgium, Ukraine and Russia were examined to look for possible evidence of the presence of Palaeolithic dogs. Reference groups constituted of prehistoric dogs, and recent wolves and dogs. The fossil large canid from Goyet (Belgium), dated at c. 31,700 BP is clearly different from the recent wolves, resembling most closely the prehistoric dogs. Thus it is identified as a Palaeolithic dog, suggesting that dog domestication had already started during the Aurignacian. The Epigravettian Mezin 5490 (Ukraine) and Mezhirich (Ukraine) skulls are also identified as being Palaeolithic dogs. Selected Belgian specimens were analyzed for mtDNA and stable isotopes. All fossil samples yielded unique DNA sequences, indicating that the ancient Belgian large canids carried a substantial amount of genetic diversity. Furthermore, there is little evidence for phylogeographic structure in the Pleistocene large canids, as they do not form a homogenous genetic group. Although considerable variation occurs in the fossil canid isotope signatures between sites, the Belgian fossil large canids preyed in general on horse and large bovids.

Diet of aurochs and early cattle in southern Scandinavia: evidence from 15N and 13C stable isotopes

Stable carbon and nitrogen isotope ratios from ¹⁴C dated bones of early Atlantic aurochs (Bos primigenius Bojanus) and late Atlantic first domestic cattle (Bos taurus Linnaeus) in eastern Denmark and southern Sweden are significantly different and provide information on the origin and feeding strategies of the two species.Radiocarbon dates generally divide the bone material of aurochs and domestic cattle in three groups: aurochs older than 4000 cal yr BP, an older group of domestic cattle around 4000 cal yr BP, and a younger, less well-defined group of domestic cattle starting at around 3500 cal yr BP. The older domestic cattle are represented mainly by fragmentary bones left over from meals, and deposited in lakes at the vicinity of the settlement areas. Bones of the younger domestic cattle group occur both as settlement debris and as single articulated skeletons in bogs, commonly in association with different types of clay pots. The latter type of finds suggests that sacrifice of domestic cattle began at this time. The dating of the early domestic cattle further indicates that they were contemporaneous with or slightly younger than the elm decline, which occurred shortly after 4000 cal yr BC on the Danish island of Sjælland. Our results indicate a sudden rapid introduction of domestic cattle into Denmark, heralding the introduction of agriculture and there is no evidence for leaf foddering or domestication of aurochs. A combination of several natural events may have created the necessary open land, providing the grazing areas for the imported cattle.     

Mobility and the diversity of Early Neolithic lives: Isotopic evidence from skeletons

Isotopic analyses of tooth enamel from early Neolithic skeletons in southern Germany adds diversity to the picture of the Neolithic transition in central Europe, which has often been described as a wholesale shift in diet and technology. Over the past decade, these isotopic studies have suggested some degree of immigration from nearby indigenous groups, as well as social differences within early Neolithic communities that correlate with immigration patterns. In general, there emerges pattern a pattern of patrilocal kinship that is consistent with independent genetic evidence, and anthropologically consistent with the potential identification of Neolithic ‘nuclear families’; and finally, specialisation of subsistence activities, such as livestock herding and cultivating, probably along hereditary lines.     

Carbon and nitrogen isotope signals in eel bone collagen from Mesolithic and Neolithic sites in northern Europe

Carbon and nitrogen isotope analysis was undertaken on collagen extracted from eel bone from six Mesolithic and Neolithic sites in northern Europe. The results were compared with data obtained on other archaeological fish remains and modern eel caught in fresh and brackish water and from the sea. The possibility of discriminating between freshwater, brackish and marine signals in archaeological eel bone is evaluated and the implications for archaeology discussed. Our data suggest that eel found at coastal Mesolithic and Neolithic sites have carbon isotope signals consistent with a marine origin with no evidence of freshwater residency. The sample of eel bone from one inland site is small but indicates carbon isotope values more consistent with freshwater residency or at least values intermediate between freshwater and marine carbon pools.     

The link between fluids and rank variation in the South Wales Coalfield: evidence from fluid inclusions and stable isotopes

Fluid inclusion and stable isotope data from quartz and carbonate minerals in fracture fillings and ‘ironstone’ nodules from the South Wales Coalfield have been used to characterise the fluids generated during basin evolution and associated coalification. Carbonates grew first, probably at relatively shallow depths and low temperatures (<100°C). The carbonates exhibit a trend of increasing C‐isotopic values across the coalfield, ranging from δ¹³C = ?12‰ VPDB in the SE of the coalfield to 0‰ VPDB in the NW, possibly as a result of increasing methanogenesis in the deeper (NW) parts of the coalfield. Quartz formed at a later stage of basin formation, probably at temperatures between 150 and 200°C. Fluid inclusions in these minerals suggest that burial and coalification of the sediments were associated with mixed aqueous–petroleum fluids. Furthermore, the density of these petroleum fluids decreases towards the NW of the coalfield, where the rank of the associated coal increases to anthracite grade. The study confirms that the composition and temperature of these fluids closely correlate with the variations in coal rank, indicating a possible causal link. The data also give general support to models that propose regional fluid flow in the basin. and are consistent with the erosion of approximately 2 km of section which is not preserved today. A geothermal gradient (at maximum burial) of 45°C km^?1 is proposed, and thus no exceptionally anomalous thermal regime is required to explain coal rank variation.     

The Living and The Dead,Memory and Transition: Bayesian Modelling of Mesolithic and Neolithic Deposits from Vlasac,the Danube Gorges

The paper applies Bayesian statistical modelling to radiocarbon dates obtained for a stratigraphic sequence comprising occupation features and superimposed burials from the Late Mesolithic (c.7400–6200 cal BC) to the Mesolithic–Neolithic transition (c.6200–5900 cal BC), from Vlasac in the Danube Gorges region of the north‐central Balkans. This sequence, investigated in the course of excavations at the site in 2006–9, yielded stratigraphic evidence of the transformation of local forager populations as a result of contact with Neolithic communities. Our paper provides a reliable chronological framework for changes from Late Mesolithic burial rites to new, Neolithic types of ornamental beads at the top of the sequence. The use of the same burial location and continuities in burial rites over a considerable period of time raise significant questions about the role of tradition and the potential for enduring practices in prehistoric societies.     

A Healed Wound Caused by a Flint Arrowhead in a Neolithic Human Innominate from the Trou Rosette (Furfooz,Belgium)

A new case is described here of a wound caused by a flint arrowhead in the neolithic period. The specimen comes from a collective burial excavated last century in the cave Trou Rosette (Belgium). It consists of a fragment of left adult ilium. The fragment of arrowhead is located in a rounded cavity which is open in the medial surface of the bone. The CT scan and the artefact study allow us to reconstruct the scenario of the accident. The arrow pierced the musculus gluteus of the individual prior fixing in the iliac blade. The arrow tip broke at the moment of impact; its tang broke either at the moment of impact or during attempts to extract the arrow.     

Paleoenvironment of Australopithecus anamensis at Allia Bay,East Turkana,Kenya: evidence from mammalian herbivore enamel stable isotopes

Carbon (¹³C:¹²C) and oxygen (¹⁸O:¹⁶O) stable isotope ratio analysis was performed on well-preserved tooth enamel carbonate from fossil fauna recovered from a single excavation at the early hominid site of Allia Bay, East Turkana, Kenya. These data show greater enrichment in both ¹²C and in ¹⁶O than expected, based on the oxygen isotope composition of the middle Pliocene ocean, and on today’s ecology. The pattern of these data argues against a diagenetic explanation for the enrichment. The carbon stable isotope data of known browsers suggest a more extensive canopy cover during the middle Pliocene than today’s environments. The presence of browsing pig genera, hippo genera, deinotheres, and giraffes with δ¹³C values more negative than today’s all argue for woodland habitats. The presence of several grazing genera point to the presence of grasslands as well. The oxygen stable isotope ratios indicate that the site was better-watered than today, although the source, seasonal pattern, and actual amount of water cannot be determined from these data. The overall mosaic of environments suggested by these data, in combination with reports of exotic trees recovered in nearby deposits, indicate that woodlands were present in the region 3.9 my, unlike today. Such a setting matches expectations for the selective advantages of nut-eating, bipedal hominids over other hominoids.     

Mapping Mesolithic and Neolithic cultures behaviours and interactions with nature and properties of rocks in Western France

Multivariate statistical methods are used to study recent Prehistory lithics from the Armorican Massif, allowing us to classify them in more or less distinct groups according to the structural and mineralogical qualities of rock types involved. Analyses are carried out on metamorphic, sedimentary and magmatic rocks making up lithics collected from 31 localities. The petrographic properties are determined by polarizing microscope (POM), while the mechanical properties are obtained by Vickers's indentation method (VI), compression/traction (CT) and ultrasound echography (UE). The results provide us with important information about the management of lithic raw materials used by various human and cultural groups during the Mesolithic and Neolithic of the Armorican Massif. The more commonly used materials show a homogeneous and stable distribution of regional technology styles. The rock types exhibiting mature and homogeneous structures possess the better qualities for knapping (fracture energy G_Ic) and use (edge toughness M₁), and are more involved in exchange. The application of Upward Hierarchical Classification (UHC) and Principal Component Analysis (PCA) allows us to identify the classes of materials as well as the causes of variations of rock type abundance within the lithic assemblages of the Mesolithic and the Neolithic. In this way, we can then also predict the discovery of archaeological artefacts in areas lacking any known indications of the exploitation of outcropping materials.
