The genomic history of the Iberian Peninsula over the past 8000 years

We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia's ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European-speaking regions but also into non-Indo-European-speaking ones, and we reveal that pre…

Cocina cave revisited: Bayesian radiocarbon chronology for the last hunter-gatherers and first farmers in Eastern Iberia

Abstract Recent excavations and radiocarbon work conducted at Cocina Cave (Valencia region, Eastern Iberia) provide new insights into the transition from foraging to farming in the eastern Iberian Peninsula between 8000 and 7300 cal yrs. BP. Cocina cave was discovered in 1940 and excavated by L. Pericot from 1941 to 1945. J. Fortea continued excavations in the 70s. Despite early international recognition and great promise of significance, the materials recovered from these excavations have only been partially analyzed and published. A new project started in 2012 is focused on these cave deposits with the main goal of understanding the occupation sequence during the neolithization process in…

Taphonomic processes inconsistent with indigenous Mesolithic acculturation during the transition to the Neolithic in the Western Mediterranean

Abstract We applied taphonomic analysis combined with geostatistical approaches to investigate the hypothesis that Cocina cave (Eastern Iberia) represents an acculturation context for the appearance of Neolithic Cardial pottery. In the 1970s, Fortea suggested that this important site was a prime example of acculturation because of the presence of early Neolithic pottery in late Mesolithic contexts. Since that time Cocina cave has been heralded as an example of indigenous hunter-gatherers incorporating Neolithic cultural elements into their lifeways. We analyzed the area excavated by Fortea in the 1970s by digitizing archaeological records and testing the spatial distribution of artifacts us…

AEA 2012 Conference Reading: Socioecological dynamics at the time of Neolithic transition in Iberia

The Western Mediterranean, spanning southern Italy to Portugal, can be considered a single archaeological unit where the diagnostic characteristics of Early Neolithic contexts share common elements, marked by the spread of Cardium-Impressed ceramics. Although some consensus exists regarding the origin of these wares in southern Italy, the debate surrounding its process of expansion to the west remains open. Iberia is a key region for the analysis of the neolithisation process due to its location at the end of the Neolithic Mediterranean expansion. This view includes the problems linked with the mechanism of this spread and the evolutionary dynamics of the early agricultural societies. Our g…

Technological style, chaîne opératoire, and labor investment of early Neolithic pottery

Se presentan los datos tecnológicos derivados del muestreo del conjunto cerámico del Neolítico antiguo de las comarcas centrales valencianas. A través de ellos se realiza una aproximación al estilo tecnológico a través del concepto de "cadena operativa" al tiempo que se discute el grado de inversión de trabajo en algunas de las producciones específicas que definen este horizonte cultural. Todo ello nos permite, entre otros aspectos, aproximarnos a la relación entre secuenca productiva, tecnología y estilo decorativo.

Colata site (Montaverner, Valencia, Spain) and the "silos settlements" duting the 4th millennium BC in the central-southern counties of the Valencian Country

Les estructures documentades al jaciment de Colata (Montaverner, València) mostren la parcialitat del registre que caracteritza aquest tipus de jaciment a l’aire lliure del IV mil·lenni aC, cosa que obliga a plantejar noves estratègies per a reinterpretar l’evolució en les conductes d’emmagatzematge, consum i producció d’aliments, i en la organització social d’aquestes comunitats. Paraules clau: Vall d’Albaida. Estructures excavades. Poblats de sitges. Patró d’assentament. Organització social.

A Bayesian Approach for Timing the Neolithization in Mediterranean Iberia

AbstractIn this paper, we compile recent14C dates related to the Neolithic transition in Mediterranean Iberia and present a Bayesian chronological approach for testing thedual model, a mixed model proposed to explain the spread of farming and husbandry processes in eastern Iberia. The dual model postulates the coexistence of agricultural pioneers and indigenous Mesolithic foraging groups in the Middle Holocene. We test this general model with more regional models of four geographical areas (Northeast, Upper, and Middle Ebro Valley, and Eastern and South/Southeastern regions) and present a filtered summed probability of all14C dates known in the region in order to compare socioecological dyn…

Analysis of stratigraphical sequences at Cocina Cave (Spain) using rare earth elements geochemistry

This study investigates the stratigraphical sequence of Cocina Cave (Spain) employing and testing for the first time the capability of rare earth elements as markers of human activities in caves. Located in Dos Aguas (Valencian Community, Spain), Cocina Cave is characterized by the presence of several Holocene archaeological deposits from the final Mesolithic to the present day and is a pivotal site for understanding the socio‐ecological dynamics of the last hunter‐gatherer inhabitants of the Iberian Peninsula and the transition to pastoral and agricultural economies in the Western Mediterranean. However, the identification of strata from particular time‐periods in the cave is often difficu…

Neolithic rock art in context: Landscape history and the transition to agriculture in Mediterranean Spain

Rock art is one of the most salient features of Neolithic societies in eastern Spain and an explicit form of landscape history. This paper summarizes current debates of Mediterranean rock art chronology and interpretation and explores the contextual differences in two areas of Neolithic settlement with rock art: the Canyoles Valley (Valencia) and the Alcoi Basin (Alicante). Large-scale survey of the Canyoles Valley resulted in a clearer understanding of agricultural land use during the Neolithic that contrasts with evidence from the Alcoi Basin. By analyzing Neolithic rock art in its archaeological context, we discuss the significance and limitations of rock art analysis for understanding a…

Actuación arqueológica en los depósitos mesolíticos de Cueva de la Cocina (Dos Aguas, Valencia) : valoración preliminar

Cavidades de uso funerario durante el Neolítico final/Calcolítico en el territorio valenciano: trabajos arqueológicos en Avenc Dels Dos Forats o Cova del Monedero (Carcaixent, Valencia)

Presentamos en este trabajo los resultados de la intervención arqueológica de urgencia efectuada en la cavidad de Avenc dels Dos Forats o Cova del Monedero (Carcaixent, Valencia) a finales del verano de 2008. Noticias preliminares informaban de la existencia de restos humanos y elementos de ajuar que indicaban un uso funerario de este espacio al menos desde el Neolítico final/Calcolítico. Con la presente actuación hemos podido dilucidar el grado de conservación del depósito arqueológico a la vez que esbozar la diacronía, características y orientación funcional de las ocupaciones prehistóricas e históricas.

Radiocarbon dates, climatic events, and social dynamics during the Early Neolithic in Mediterranean Iberia

Abstract Our goal in this paper is to examine the socioecological dynamics of the Early Neolithic period in Iberia in order to test the usefulness of temporal probability curves built from dated sites as a relative proxy for exploring possible links between trends in population patterns and climatic fluctuations. We compare the information for the entire Iberian Peninsula with four Mediterranean regions, investigating the climate–population relationships that emerge when we zoom into particular regions. We evaluate climatic and other possible causes of similarities in the shapes of temporal probability curves across the Peninsula, associated with demographic changes in the Early Neolithic s…

AMS DATING OF HUMAN BONE FROM COVA DE LA PASTORA: NEW EVIDENCE OF RITUAL CONTINUITY IN THE PREHISTORY OF EASTERN SPAIN

We present the results of 10 AMS radiocarbon dates for Cova de la Pastora (Alcoi, Alicante), a burial cave attributed to the Late Neolithic/Chalcolithic in eastern Spain. The direct dating of 10 human mandibles from Cova de la Pastora indicates that the cave was used as a burial place from the Late Neolithic/Chalcolithic to the Bronze Age. These dates reveal a continuity of ritual use not previously identified at the site. This case also serves to highlight the utility of revisiting historic excavations and museum collections with modern techniques to shed new light on the prehistoric human record.

Increasing contextual information by merging existing archaeological data with state of the art laser scanning in the prehistoric funerary deposit of Pastora Cave, Eastern Spain

Abstract In this paper we present a virtual reconstruction of prehistoric funerary practices in Pastora Cave, a collective burial site in Eastern Spain that dates from the Late Neolithic, Chalcolithic and Bronze Age. Modern data of the cave was captured by 3D laser scanning techniques and added to recorded archaeological data and 3D graphic information. The combination of these data sets allowed us to create a hypothetical reconstruction to analyze the material excavated in the 1940s and 50s in greater spatial context. A 3D model of the current cave was created in order to serve as a basis for modeling the relative stratigraphic information available. We present the methodology employed and…

Osteological and paleodietary investigation of burials from Cova de la Pastora, Alicante, Spain

We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800e3000 cal BC), Chalcolithic (ca. 3000 e2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500e2200 cal BC) and the Bronze Age (ca. 2200e1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by ev…
