La gestión de los recursos faunísticos durante el Neolítico en la Sierra de Atapuerca (Burgos): los niveles 19 y 20 de la Cueva del Mirador

The archaeozoological and taphonomical analyses of the faunal remains from levels 19 and 20 in the Mirador cave (Sierra of Atapuerca, Burgos) are presented. The main aim of this work is threefold: to study how faunal resources were managed, to characterize the occupation of the cave and to understand how the environmental resources were exploited at the end of the sixth millennium and the beginning of the fifth millennium cal. BC. Results show the development of human communities with a complex organization and a great environmental adaptation. Shepherds used the cavity as a sheepfold and as a domestic space during almost all the year. Sheep and goat husbandry comprised the economic basis; these taxa were exploited mainly for their meat and milk. Breeding of cattle and hunting would have been complementary activities.En este trabajo se presentan los datos obtenidos a partir del análisis zooarqueológico y tafonómico de los restos faunísticos recuperados en los niveles 19 y 20 de la Cueva del Mirador (Sierra de Atapuerca, Burgos). El objetivo fundamental ha sido obtener información sobre la gestión de los recursos faunísticos y las características de ocupación de la cavidad y aprovechamiento del entorno durante el final del VI milenio y los inicios del V milenio cal. BC. Los resultados han mostrado el desarrollo de comunidades con una estructuración compleja y una gran adaptación a su entorno. La cavidad fue empleada por un grupo de agricultores y ganaderos, tanto como redil para el ganado como espacio doméstico y durante la práctica totalidad del año. La economía ganadera se basaría en la cría de ganado ovicaprino, explotado tanto para la obtención de carne como de leche. Esta práctica económica estaría complementada por la cría de ganado bovino y las prácticas cinegéticas

Hormones and bile acids as biomarkers for the characterization of animal management in prehistoric sheepfold caves: El Mirador case (Sierra de Atapuerca, Burgos, Spain

Early husbandry practices that include herd management and the use of livestock areas such as sheepfold caves can be analysed in the context of different disciplines (e.g. zooarchaeology, micromorphology, and archaeobotany). In this study, a new and standard method for the determination of bile acids and steroidal hormones that incorporates microwave extraction-liquid chromatography-mass spectrometry was used. This method has been applied successfully to analyse Neolithic fumier deposit facies from the El Mirador cave, a location that was used as a prehistoric sheepfold and is located in the Atapuerca range (Burgos, Spain). The results obtained demonstrated that the analysis of bile acids can be useful for the identification of remains of ruminant residues in the facies studied. In addition, the progesterone/deoxycholic acid ratio has been used as a possible biomarker to improve our understanding of flock management, including the separation of pregnant and nursing ewes from the rest of the herd to avoid the rejection of the lamb and keep them safe and healthy.The authors thank the technical and human support provided by the Alava Central Service of Analysis of SGIker (UPV/EHU, MINECO, GV/ EJ, ERDF, and ESF) and Paula Rivero for the elaboration of the graphical abstract.

La sierra de Atapuerca durante el Holoceno: datos preliminares sobre las ocupaciones de la Edad del Bronce en la Cueva de El Mirador (Ibeas de Juarros, Burgos)

The paper presents data from the El Mirador cave, part of the Sierra de Atapuerca project. The data deriving from the first two stratigraphical excavation campaigns (1999 and 2000) are illustrated. A 2.5-m thick Holocene succession, containing Neolithic and Bronze Age occupations, was excavated and sampled using a multidisciplinary perspective. Preliminary data on the Bronze Age occupations indicate the utilization of the rock-shelter for various activities, among them animal stabling, habitation and burial. Animal stabling led to the accumulation of characteristic burnt layers, never seen before in the Meseta region or in wider European context. A Bronze Age collective burial showing evidence of pre-treatment of bodies before their deposition, and a stratified metal axe, were also found.Las excavaciones arqueológicas iniciadas en 1999 en la cueva de El Mirador de la sierra de Atapuerca han permitido documentar hasta el momento una sucesión estratigráfica holocena de unos 2,5 m de potencia, formada por niveles del Neolítico y de la Edad del Bronce. Los datos preliminares sobre las ocupaciones de la Edad del Bronce señalan el uso de la cueva como redil, zona de hábitat y espacio sepulcral. Durante su uso como redil se llevó a cabo la quema periódica del estiércol depositado en el interior del corral. Es la primera vez que dicha práctica se documenta en la Meseta y, en el ámbito europeo, en contexto geográfico continental. El uso como cueva sepulcral viene seña- lado por la presencia de una inhumación colectiva. Ésta presenta evidencias de un ritual relacionado con el tratamiento de los cadáveres previo a su enterramiento. Cabe subrayar también la presencia de una hacha de bronce de rebordes en contexto estratigráfico

Nuevos datos para el Neolítico antiguo en el nordeste de la Península Ibérica procedentes de la Cova del Toll (Moià, Barcelona) y de la Cova de la Font Major (L’Espluga de Francolí, Tarragona)

Since the 1950s, archaeological activity has been especially prolific in Spanish regions such as Catalonia. This process brings the possibility to discover and excavate some of the most important archaeological sites in order to study the main cultural events in the past. This has been the case of Cova del Toll and Cova de la Font Major, whose cardial pottery collections have been a reference for the study of the Early Neolithic. However, methodological procedures employed at that moment do not help to give a strong, contextaulised dataset. In this work we present the results of the interventions carried out in both sites between 2006 and 2011. The combination of new Early Neolithic remains and short-lived C14 AMS dates has allowed us to put back the cardial phase of Cova del Toll, as well as to date for the first time de Early Neolithic of Cova de la Font Major.La reactivación de la actividad arqueológica española a partir de los años 1950, especialmente prolífica en algunas regiones como Cataluña, incorporó algunos yacimientos clave para el conocimiento de los grandes procesos culturales del pasado. Es el caso de las cuevas del Toll y Font Major cuyas colecciones de cerámica cardial, por su cantidad y calidad, han sido de referencia para el Neolítico antiguo en distintos momentos. En cambio cuentan con pocos o nulos datos contextuales debido a los métodos que se emplearon en esas primeras intervenciones. En este trabajo se presentan los resultados de las realizadas entre 2006 y 2011 en ambos yacimientos. La combinación de nuevos materiales encuadrables en distintas fases del Neolítico antiguo cardial con fechas radiocarbónicas de muestras de vida corta nos permite retrasar sensiblemente la fase cardial de la Cova del Toll, así como fechar por primera vez de forma absoluta la fase cardial de la Cova de la Font Major

The first hominin of Europe

The earliest hominin occupation of Europe is one of the most debated topics in palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in Eurasia lack precise age control and contain stone tools rather than human fossil remains(1-5). Here we report the discovery of a human mandible associated with an assemblage of Mode 1 lithic tools and faunal remains bearing traces of hominin processing, in stratigraphic level TE9 at the site of the Sima del Elefante, Atapuerca, Spain(6-8). Level TE9 has been dated to the Early Pleistocene ( approximately 1.2 - 1.1 Myr), based on a combination of palaeomagnetism, cosmogenic nuclides and biostratigraphy. The Sima del Elefante site thus emerges as the oldest, most accurately dated record of human occupation in Europe, to our knowledge. The study of the human mandible suggests that the first settlement of Western Europe could be related to an early demographic expansion out of Africa. The new evidence, with previous findings in other Atapuerca sites ( level TD6 from Gran Dolina(9-13)), also suggests that a speciation event occurred in this extreme area of the Eurasian continent during the Early Pleistocene, initiating the hominin lineage represented by the TE9 and TD6 hominins.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62855/1/nature06815.pd

Genome-wide patterns of selection in 230 ancient Eurasians

Ancient DNA makes it possible to directly witness natural selection by analyzing samples from populations before, during and after adaptation events. Here we report the first scan for selection using ancient DNA, capitalizing on the largest genome-wide dataset yet assembled: 230 West Eurasians dating to between 6500 and 1000 BCE, including 163 with newly reported data. The new samples include the first genome-wide data from the Anatolian Neolithic culture whose genetic material we extracted from the DNA-rich petrous bone and who we show were members of the population that was the source of Europe’s first farmers. We also report a complete transect of the steppe region in Samara between 5500 and 1200 BCE that allows us to recognize admixture from at least two external sources into steppe populations during this period. We detect selection at loci associated with diet, pigmentation and immunity, and two independent episodes of selection on height

Palaeoenvironmental and palaeoclimatic approach of the middle bronze age (level MIR 4) from El Mirador Cave (Sierra de Atapuerca, Burgos, Spain)

This article undertakes a palaeoenvironmental and palaeoclimatic reconstruction of the Middle Bronze Age on the basis of a study of the small mammals from level MIR 4 of El Mirador Cave. The chronology of the level under study is 3,720-3,140 cal. yr BP. The palaeoenvironmental analysis indicates that it represents the period of transition between the Subboreal and the Subatlantic, during which prevailed a very humid habitat, dominated by woodland and wet meadows. Otherwise, the palaeoclimatic analysis, carried out using the Mutual Climatic Range method (MCR), reveals that level MIR 4 falls within an interval in which the temperatures were very similar to present-day ones, while mean annual precipitation was notably higher than at present, i.e. 485 mm above the present level for Burgos.Cet article propose une reconstitution paléoenvironnementale et paléoclimatique de l’Âge du Bronze moyen à partir de l’étude des petits mammifères du niveau MIR 4 de la grotte El Mirador. La chronologie du niveau étudié est comprise entre 3 720-3 140 ans cal. BP. L’analyse paléoenvironnementale indique qu’il s’agit d’une période de transition entre le Subboréal et le Subatlantique, où prédomine un habitat très humide, dominé par la forêt et les prairies humides. Par ailleurs, l’analyse paléoclimatique, basée sur la méthode du Domaine Climatique Commun (MCR) révèle que le niveau MIR 4 appartient à un intervalle dans lequel les températures sont similaires aux températures actuelles, alors que les précipitations moyennes annuelles étaient notablement supérieures, i.e. 485 mm au dessus des moyennes actuelles pour Burgos
