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…
Stable isotope ratio analysis of bone collagen as indicator of different environments conditions and dietary habits in Northeastern Iberia during the 4th and 3rd millenium calBC
The Late Neolithic and Chalcolithic periods are poorly understood in northeastern Iberia. Most of the information comes from the sepulchral structures rather than habitat settlements. The high number of individuals usually recovered from this types of collective burial spaces, together with the low number of direct radiocarbon dates available on them, forces us to be cautious and consider all the studied assemblages as belonging to the so-called Late Neolithic-Chalcolithic time period. To evaluate human dietary patterns of the Late Neolithic-Chalcolithic populations from the northeast of Iberia, stable carbon and nitrogen isotope analysis was carried out on 78 humans and 32 faunal bones fro…
Primeros resultados sobre la función del utillaje lítico de las primeras comunidades neolíticas asentadas en Les Guixeres de Vilobí (Sant Martí Sarroca, Barcelona)
Entendemos que el reconocimiento de la función de los instrumentos líticos puede aproximarnos a las actividades que realizaban las primeras comunidades neolíticas que se asentaron en el noreste de la Península Ibérica. Uno de los contextos donde poder abordar tales cuestiones es el yacimiento al aire libre de Les Guixeres de Vilobí. Perteneciente al neolítico antiguo, es uno de los pocos asentamientos de este periodo con estructuras internas y un número relevante de útiles líticos. En este trabajo presentamos una primera aproximación a la morfología, la tecnología y la funcionalidad de dicho utillaje. Su localización en el área excavada nos permite evaluar si hay una organización del espaci…
