Spatial dimensions increase the effect of cultural drift

The transition from hunter-gathering to agriculture (Neolithic) spread gradually across Europe from the Southeast. A reduction in cultural diversity of crop farming practices has been previously observed by comparing pre-LBK Neolithic sites in Greece and the Balkans (dated about 8500 yr BP) to LBK Neolithic sites in Central Europe (dated about 7000 yr BP). The decrease in crop diversity is statistically significant even when considering only the species less likely to have been subject to smaller productivity due to climatic factors (reductions in growing season, temperature, daylight, etc.). This reduction in cultural diversity has not been explained previously. In this paper we show that spatial drift, which occurred on the front of the advancing wave of pioneer settlements, can explain the observed loss of diversity during the LBK range expansion. Our results suggest that spatial dimensions can have a relevant effect also in other case studies in which cultural drift is important.     

The Neolithic Transition in the Iberian Peninsula: Data Analysis and Modeling

We apply GIS techniques to analyze a carefully selected database of 93 Early Neolithic sites in the Iberian Peninsula. This allows us to study the spatial dynamics of the Neolithic transition in Iberia. We study how the Neolithic was introduced into the peninsula in order to test the hypothesis that the Neolithic was introduced almost simultaneously from two sources: one at the northeast (via the Mediterranean coast) and another one at the south (possibly from Northern Africa). We also analyze how the expansion of the Neolithic transition took place within the Iberian Peninsula and measure local rates of spread in order to identify regions with fast and slow rates (such as the slowdown at the Cantabrian coast). In addition, we attempt to reproduce the main results obtained from the GIS analysis by applying reaction–dispersal models to the expansion of the Neolithic transition in the Iberian Peninsula. We conclude that a model with two sources is a reasonable assumption that agrees better with the archaeological data available at present than a model with a single source.     

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.     

The Changing Face of Neolithic and Bronze Age Ireland: A Big Data Approach to the Settlement and Burial Records

This paper synthesizes and discusses the spatial and temporal patterns of archaeological sites in Ireland, spanning the Neolithic period and the Bronze Age transition (4300–1900 cal BC), in order to explore the timing and implications of the main changes that occurred in the archaeological record of that period. Large amounts of new data are sourced from unpublished developer-led excavations and combined with national archives, published excavations and online databases. Bayesian radiocarbon models and context- and sample-sensitive summed radiocarbon probabilities are used to examine the dataset. The study captures the scale and timing of the initial expansion of Early Neolithic settlement and the ensuing attenuation of all such activity—an apparent boom-and-bust cycle. The Late Neolithic and Chalcolithic periods are characterised by a resurgence and diversification of activity. Contextualisation and spatial analysis of radiocarbon data reveals finer-scale patterning than is usually possible with summed-probability approaches: the boom-and-bust models of prehistoric populations may, in fact, be a misinterpretation of more subtle demographic changes occurring at the same time as cultural change and attendant differences in the archaeological record.     

Processing the dead in neolithic orkney

Summary Megalithic tombs are a characteristic feature of Neolithic Orkney and have formed the focus of numerous studies. This article examines the surviving human skeletal remains found within these cairns in the hope of determining how the dead were processed during this period of prehistory. It is shown that the fate of the body was a long and complicated affair, which involved elements of both direct interment and excarnation. It is argued that the archaeological evidence reveals that in most cases an articulated corpse was directly interred in a tomb and then subsequently dismembered until only the skull remained. This process seemingly occurred amongst several cairns during the earlier Neolithic, and during the later Neolithic the practice was restricted to the confines of a single exclusive passage grave.     

Neolithic Transhumance in the Black Forest Mountains,SW Germany

Abstract

The presence of Neolithic people in mountainous areas of Central Europe is a debated topic and there is a lack of systematic fieldwork to explore patterns of land use in upland regions. The results of two survey campaigns in the Black Forest mountains of SW Germany aid our understanding of Neolithic expansion into the uplands. An extensive inventory of flint artifacts dating predominantly from the Late Neolithic provides evidence of summer highland pasturing and leaf foddering.     

Detection of diffusion and contact zones of early farming in Europe from the space-time distribution of 14C dates

The spread of early farming in Europe is revisited using a sample of 3072 audited 14C calBC dates from 940 georeferenced early Neolithic sites. The surface expansion of early Neolithic has been reconstituted using the kriging technique of spatial interpolation. Centres of renewed expansion, of contact zones, and the main routes of expansion have been highlighted by means of a vector map, representing the gradient. The expansion of the agricultural system on the map, was not uniform and regular across Europe as a whole, but proceeded in leaps. With the scale of detection of the 500-year isochrones, several leaps are identifiable: at 8000 calBC crossing the Taurus barrier, 6700–6100 calBC crossing the southern Adriatic barrier, 6100–5600 calBC crossing the Central European agro-ecological barrier and 5000–4000 calBC expanding on the other, marginal zones. Using a vector map, 10 points of renewed expansion and nine contact zones, were detected. The whole does not correspond to a process of homogeneous diffusion, approximately steady, but a process marked by phases of geographical expansion and stasis.     

Ancient DNA insights from the Middle Neolithic in Germany

Genetic studies of Neolithic groups in central Europe have provided insights into the demographic processes that have occurred during the initial transition to agriculture as well as in later Neolithic contexts. While distinct genetic patterns between indigenous hunter-gatherers and Neolithic farmers in Europe have been observed, it is still under discussion how the genetic diversity changed during the 5,000-year span of the Neolithic period. In order to investigate genetic patterns after the earliest farming communities, we carried out an ancient mitochondrial DNA (mtDNA) analysis of 34 individuals from Wittmar, Germany representing three different Neolithic farming groups (ca. 5,200–4,300 cal bc) including Rössen societies. Ancient DNA analysis was successful for six individuals associated with the Middle Neolithic Rössen and observed haplotypes were assigned to mtDNA haplogroups H5, HV0, U5, and K. Our results offer perspectives on the genetic composition of individuals associated with the Rössen culture at Wittmar and permit insights into genetic landscapes in central Europe at a time when regional groups first emerged during the Middle Neolithic.     

Foraging,Farming, and Social Complexity in the Pre-Pottery Neolithic of the Southern Levant: A Review and Synthesis

The transition from foraging to farming of the Neolithic periods is one of, if not, the most important cultural processes in recent human prehistory. Integrating previously published archaeological materials with archaeological research conducted since 1980, the first half of this essay synthesizes our current understanding of archaeological data for the Pre-Pottery Neolithic period (ca. 11,700–ca. 8400 B.P.) of the southern Levant, generally defined as including southern Syria and Lebanon, Israel, the Palestinian Autonomous Authority, Jordan, and the Sinai peninsula of Egypt. The second half of the essay explores how these data inform archaeologists about the processes by which social differentiation emerged, the nature of regional and interregional connections, and the mechanisms and processes by which the transition from foraging to food production first occurred in the Neolithic.     

Hesitant hunters: a review of the introduction of agriculture in western Norway

Abstract

Evidence for the introduction of agriculture in western Norway is presented, using three categories of data: (1) palaeobotanical data, including pollen diagrams from lakes, bogs and archaeological sites, focusing on the presence of cereals, Plantago lanceolata L. and anthropogenic pollen indicators, and charred macro remains of cereals from archaeological sites; (2) osteological data, focusing on the occurrences of bones of cattle, sheep and goats in three rock-shelters, and the bone material from one open-air Neolithic site; (3) archaeological data, including artefacts indicating agricultural practices, distribution of residential settlement sites, and stray finds. The evidence for agricultural activity at the beginning of the fourth millennium BC (Early Neolithic, EN) is low, whereas the presence of both cereals and animal husbandry is indicated in the palaeobotanical material from the Middle Neolithic A (MNA, 3400–2600 cal. BC). The earliest record of domesticated animal bones is dated to the Middle Neolithic B (MNB, 2600–2200 cal. BC), while palynological and archaeological data also indicate an expansion in the area cultivated by early farmers. All data confirm the establishment of an agrarian society and animal husbandry in the Late Neolithic (LN, 2200–1700 cal. BC). It is concluded that agriculture was introduced into western Norway by the indigenous hunter-fisher populations. During this process, social and ideological factors played principal roles.     

Regional Demographic Dynamics in the Neolithic Transition in Iberia: Results from Summed Calibrated Date Analysis

This paper assesses long-term trends in human activity across the Iberian Peninsula associated with the spread of agriculture. In order to improve our understanding of regional trajectories within the two-way and multiple-velocity model proposed by Isern et al. (Journal of Archaeological Method and Theory 21:447–460, 2014), we consider summed calibrated radiocarbon dates of a large audited dataset from across Iberia. To assess the role of different analytical units, two alternative peninsular divisions at different spatial resolutions were used: one, with three generalized study areas, and the second, with eight biogeographic regions. This comparison of spatio-temporal variability provides a more in-depth inter-regional reading of the Neolithic transition in Iberia than more generalized approaches. The southwest, Mediterranean coasts and interior portions of Iberia all showed significant demographic expansion with the onset of the Neolithic, as observed across Western Europe. By contrast, northern Iberia featured a close adherence to a null model of exponential growth and a longer continuation of hunter-gatherer strategies.     

Founder effect, drift, and adaptive change in domestic crop use in early Neolithic Europe

We document and quantify a significant reduction in crop diversity in the early central European Neolithic using a large multi-site database of archaeobotantical remains we compiled from published Neolithic sites across southwest Asia and Europe. Two hypotheses are proposed to account for the observed changes: one which claims that the different environmental conditions of central Europe selected for a different set of crop choices and strategies than in use in southeast and Mediterranean Europe; and a null hypothesis that explains the change as a drift process associated with a small founding population that subsequently undergoes rapid expansion. Through an agent-based simulation model, we test the null hypothesis and demonstrate that the drop in diversity exceeds that predicted by a drift process. We conclude by re-evaluating the possible adaptive changes underlying crop use in early Neolithic Europe.     

An example of the establishment of the Bronze Age cultural landscape in SW Scandinavia

In the Lake Hullsjön area, Västergötland, SW Sweden, the increase in the deposits of artifacts, the erection of monumental graves, and the intensification and expansion of cultivation and grazing, is discussed in terms of cultural landscape changes at the Neolithic/Bronze Age transition c. 2500–1500 B.C. The expansion included an intensified use of low‐lying clayey areas and caused an increase in soil erosion, as indicated by the sediment stratigraphy.     

WATER, ANIMALS AND AGRICULTURAL TECHNOLOGY: A STUDY OF SETTLEMENT PATTERNS AND ECONOMIC CHANGE IN NEOLITHIC SOUTHERN GREECE

Summary. This study, based on evidence from archaeological surveys and excavations in southern Greece, demonstrates two major shifts in the subsistence economy during the Neolithic. In the EN and MN periods the presence of large villages in locations near reliable water-sources and permanently moist or seasonally flooded soils of high and sustained productivity illustrates a village farming economy concentrating on arable agriculture. The first economic shift occurred in the late MN-LN with occupation of highland caves and islands, indicating increased sheep/goat pastoralism, fishing, and perhaps hunting, with a reduced number of farming villages present in the plains. The second shift took place in the FN-EBA, when a dispersal of agricultural settlements into dry upland regions indicates expanding plough agriculture and pastoralism, important factors contributing to the development of the flourishing EBA economy. The expansion of settlement was most marked in southeastern Greece, and it is suggested here that the extensive grazing areas provided by the open vegetation and mountainous terrain of this dry region, and its relative scarcity of well-watered fertile lowlands, may have stimulated the LN-FN expansion of pastoralism.     

Mobility and Social Change: Understanding the European Neolithic Period after the Archaeogenetic Revolution

This paper discusses and synthesizes the consequences of the archaeogenetic revolution to our understanding of mobility and social change during the Neolithic period in Europe (6500–2000 BC). In spite of major obstacles to a productive integration of archaeological and anthropological knowledge with ancient DNA data, larger changes in the European gene pool are detected and taken as indications for large-scale migrations during two major periods: the Early Neolithic expansion into Europe (6500–4000 BC) and the third millennium BC “steppe migration.” Rather than massive migration events, I argue that both major genetic turnovers are better understood in terms of small-scale mobility and human movement in systems of population circulation, social fission and fusion of communities, and translocal interaction, which together add up to a large-scale signal. At the same time, I argue that both upticks in mobility are initiated by the two most consequential social transformations that took place in Eurasia, namely the emergence of farming, animal husbandry, and sedentary village life during the Neolithic revolution and the emergence of systems of centralized political organization during the process of urbanization and early state formation in southwest Asia.

     

Understanding the rates of expansion of the farming system in Europe

If the overall expansion of the farming system was determined by the Neolithic Demographic Transition (NDT), i.e. by demographic pressure, what determined the rate of expansion? What is the link between the rate of expansion, the farming system and demographic density? In a first approach, the issue of the different rates of expansion of the farming system on the map is addressed in terms of 21 geo-ecological, climatic and cultural factors and forager populations, via an ordinary least square regression technique (OLS). In a second approach, the variability of the rate of expansion is analyzed in terms of specific patterns identified for the ceramic culture areas, via a cluster analysis. The expansion rate is negatively correlated with the intensification of the agricultural system, as well as with demographic density. Expansion is slow in ecosystems with an intensive farming system with relatively high demographic density, and vice-versa.     

Early farming in hordaland,western Norway. Problems and approaches in archaeology and pollen analysis

This article discusses the evidence of farming settlements in Neolithic times in the county of Hordaland, in western Norway, and possible ways for future research to establish the introduction of a farming economy, with its cultural and ecological implications.

Using distribution maps, Bakka demonstrates how the people of the mainly hunting and fishing sub‐Neolithic dwelling‐place culture of the Middle Neolithic period preferred a coastal area of habitation, while the find groups of Neolithic artifacts are generally to be found in those areas more suitable for farming. This change of habitat is interpreted as evidence of a general change in economic structure, with a greatly increased emphasis on agriculture.

Kaland discusses the Sub‐Boreal history of vegetation in Hordaland as revealed by pollen analysis. The earliest phase of agriculture in the pollen diagrams is dated in relation to the pollenanalytical leading horizons, the shore‐line displacement, radiocarbon measurements and the archaeological chronology. He puts forward the working hypothesis that in the sub‐Neolithic culture of the Middle Neolithic period some animal husbandry may have been practised in zone VIII b as a supplementary means of livelihood, and that this was followed by a phase of cereal growing in zone VIII c. The Late Neolithic culture appears to be responsible for this more intensive mixed farming, and this corresponds to the archaeological evidence of the introduction of cereal cultivation, which demands the better‐soils of the later farming land.     

The Neolithic of the eastern Baltic

This survey of the Baltic Neolithic, from Vistula to the Gulf of Finland, highlights the results of research during the last 30 years. The primary Baltic Neolithic is represented by two indigenous cultures, Narva and Nemunas. Their hunting, fishing, and gathering subsistence strategies gradually expanded to include domesticated plants and animals. The Comb-and-Pit Ornamented Pottery, Globular Amphora, Corded Ware, Bay Coast, and Boat-Axe cultures are also described. Within the Baltic Neolithic, I emphasize the origin, technology, economy, settlement, ritual, ethnic origins, and relationships among the various Neolithic populations. There is then a discussion of the origin of the Baltic linguistic group (Latvian, Lithuanian, and Old Prussian); this is associated with the appearance of the Late Neolithic Corded Ware culture, whose people integrated with local populations, leading to the development of the Bay Coast culture. Late Neolithic developments are associated with the Finno-Ugrian linguistic group in the northern Baltic.     

Impulses of agro-pastoralism in the 4th and 3rd millennia BC on the south-western coastal rim of Norway

Abstract

A review of the available archaeological and palaeoecological evidence from the coastal heathlands of south-western Norway was compiled to reveal the processes of neolithisation proceeding from the Early Neolithic towards the generally accepted breakthrough in the Late Neolithic, 2500/2350 cal. BC. South-western Norway then became part of the Scandinavian, and thus the European, agricultural complex. Three phases of forest clearance are recorded — from 4000–3600 cal. BC, 2500–2200 cal. BC and 1900–1400 cal. BC. Deforestation was intentional and followed a regional pattern linked to the geology and topography of the land. In the first period (4000–2500 cal. BC), forage from broad-leaved trees was important, while cereal cultivation was scarcely recorded. Agro-Neolithic (here referring to agriculturally-related Neolithic) artefacts and eco-facts belonging to the Funnel Beaker and Battle Axe culture are rare, but pervasive. They must primarily be considered to be status indicators with a ritual function; the hunter-gatherer economy still dominated. The breakthrough in agro-pastoral production in the Late Neolithic was complex and the result of interactions between several variables, i.e. a) deforestation resulting from agriculture being practised for nearly 1500 years b) experience with small-scale agriculture through generations and c) intensified exchange systems with other South Scandinavian regions. From 2500/2350 cal. BC onwards, two distinct environmental courses are noticeable in all pollen diagrams from the study area, indicating expansion in pastoralism, either towards heath or towards grassland and permanent fields.
