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…
New data on Sicilian prehistoric and historic evolution in a mountain context, Vallone Inferno (Scillato, Italy)
Vallone Inferno rock-shelter is an archaeological site located in the Madonie mountain range in Sicily. Archaeological excavation and research have provided a long prehistoric and historic sequence from the Neolithic to the medieval period, this being the most complete work in this area at present. In this paper we present the preliminary data provided by a multidisciplinary study based on pottery, lithic, human, faunal and plant remains. Stratigraphic studies have identified four complexes, of which complex 3 has provided almost all the archaeological remains. 14C AMS dates, obtained from four samples, place the human activities between 2601 cal BC and 644 cal AD. These dates are coherent …
Hàbitat en cova i espai pels ramats ca. 6200-6000 BP: dades preliminars de la Cova Colomera (Prepirineu de Lleida) durant el neolític antic
En aquest treball es presenten les dades referents a la Cova Colomera (Sant Esteve de la Sarga, Pallars Jussa) durant el Neolitic cardial final. A partir dels diferents sondejos duts a terme des de l’any 2005, s’ha pogut observar la varietat d’usos i funcionalitats del jaciment en moments potencialment sincronics. Per una banda, una zona on predominen les estructures de caire domestic (fogars, fosses i forats de pal) que ens mostren les dades entorn l’habitat al jaciment; i per altra banda, un gran sector de la cavitat dedicat a l’estabulacio de ramats amb sediments de tipus fumier i probablement tambe a l’emmagatzematge. Tot aixo succeeix en unes datacions d’entre 6180±40 i 6020±50 BP. Aq…
