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

2019

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…

Comercio protohistórico: el registro del Nordeste peninsular y la circulación de mineral de plomo en Ibiza y el Bajo Priorato (Tarragona)

2012

[ES] Los estudios que hemos venido realizando indican que el plomo de la cuenca minera del Bajo Priorato (Tarragona) circula en el ámbito fenicio-tartesio. Sin embargo, los análisis realizados sobre un conjunto de muestras minerales y metálicas de la isla de Ibiza ponen de manifiesto la explotación de la galena argentífera local, cuyo uso coexiste en el yacimiento de sa Caleta con el mineral de Cartagena; no se documenta, en cambio, plomo de procedencia prioratina. Si sumamos a ello los datos relativos a las evidencias que aportan los registros cerámicos ibicencos y catalanes de los ss. VII a VI a.n.e., se va trazando un panorama que pone en evidencia la existencia de una pluralidad de rede…
