A simulation of the Neolithic transition in Western Eurasia

Farming and herding were introduced to Europe from the Near East and Anatolia; there are, however, considerable arguments about the mechanisms of this transition. Were it people who moved and outplaced the indigenous hunter- gatherer groups or admixed with them? Or was it just material and information that moved-the Neolithic Package-consisting of domesticated plants and animals and the knowledge of its use? The latter process is commonly referred to as cultural diffusion and the former as demic diffusion. Despite continuous and partly combined efforts by archaeologists, anthropologists, linguists, paleontologists and geneticists a final resolution of the debate has not yet been reached. In the present contribution we interpret results from the Global Land Use and technological Evolution Simulator (GLUES), a mathematical model for regional sociocultural development embedded in the western Eurasian geoenvironmental context during the Holocene. We demonstrate that the model is able to realistically hindcast the expansion speed and the inhomogeneous space-time evolution of the transition to agropastoralism in Europe. GLUES, in contrast to models that do not resolve endogenous sociocultural dynamics, also describes and explains how and why the Neolithic advanced in stages. In the model analysis, we uncouple the mechanisms of migration and information exchange. We find that (1) an indigenous form of agropastoralism could well have arisen in certain Mediterranean landscapes, but not in Northern and Central Europe, where it depended on imported technology and material, (2) both demic diffusion by migration or cultural diffusion by trade may explain the western European transition equally well, (3) [...]Comment: Accepted Author Manuscript version accepted for publication in Journal of Archaeological Science.

Shifting occupation dynamics in the Madriu-Perafita-Claror valleys (Andorra) from the early Neolithic to the Chalcolithic: the onset of high mountain cultural landscapes

The Madriu–Perafita–Claror valleys (MPCV) (Eastern Pyrenees, Andorra) were the focus of a multidisciplinary microregional landscape research project that aimed to study the long term shaping of this UNESCO World Heritage Site in the category of cultural landscape. The study area is situated on a glacial modelled high mountain environment ranging from 1250 to 2800 m.a.s.l. Multidisciplinary approaches integrating archaeology and palaeoenvironment have been directed towards the unravelling of the long-term human–landscape relationships, which ultimately resulted in the MPCV cultural landscape. The development of high-resolution temporal and spatial studies could successfully correlate archaeological and palaeoenvironmental data. This study leads to the location of more than 400 archaeological structures, 55 of which were excavated, and the multiproxy study of 7 palaeoenvironmental sequences. The combination and analysis of all these data have permitted developing a history of human–environment interactions from the Mesolithic to the 20th century. In this paper, data gathered in the MPCV corresponding to the Neolithic and Chalcolithic periods are presented for the first time. During the Early Neolithic small groups are documented with a diversified economy in which grazing, hunting, fishing, gathering and an incipient cereal agriculture activities are well represented. These groups seem to follow highly mobile occupation patterns with continuous high mountain seasonal grazing exploitations that lasted one or two centuries. They appear to frequent diverse altitudinal belts in order to take advantage of different resources. A strong pastoral orientation is related to the exploitation of high mountain areas. During the Middle/late Neolithic human groups show a higher degree of sedentism. Hunting and gathering are still important activities although agriculture and animal husbandry increase in importance. During this period an augmentation in the pastoral pressure in the MPCV is also documented, linked to the first use of fires to create grazing areas. Symbolic landscape appropriation practices are also firstly documented during this period. During the Chalcolithic, human landscape use becomes intensive enough to cause permanent landscape changes. The upper parts of the MPCV are deforested by the action of fire while intensive agriculture takes place at the lower valleys. The evidence presented by the MPCV project demonstrates that it was during the Neolithic when this high mountain cultural landscape was firstly formed. This process is probably related to an increase in the population and progressive sedentism, which required a more intensive and organised use of resources and, eventually, the adoption of landscape management practices

The Neolithic transition in the western Mediterranean: a complex and non-linear diffusion process—The radiocarbon record revisited

International audienceThe Neolithic transition is a particularly favorable field of research for the study of the emergence and evolution of cultures and cultural phenomena. In this framework, high-precision chronologies are essential for decrypting the rhythms of emergence of new techno-economic traits. As part of a project exploring the conditions underlying the emergence and dynamics of the development of the first agro-pastoral societies in the Western Medi-terranean, this paper proposes a new chronological modeling. Based on 45 new radiocarbon (14 C) dates and on a Bayesian statistical framework, this work examines the rhythms and dispersal paths of the Neolithic economy both on coastal and continental areas. These new data highlight a complex and far less unidirectional dissemination process than that envisaged so far
