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…
El hacha de jadeíta de Portela do Outeiro (Sertã, Castelo Branco, Portugal)
2015
Este artículo trata sobre el análisis arqueométrico de un hacha de jadeíta depositada en el Museo do Clube da Sertã, en la villa de Sertã (distrito de Castelo Branco, Portugal). De igual forma que sucede en otros museos creados en el s. XIX y comienzos del s. XX, éste incorpora materiales arqueológicos aislados y con escasas referencias al contexto de origen. El hacha en cuestión tan sólo cuenta con una fcha de inventario manuscrita en la que aparece la siguiente descripción (fg. 1): Pedra exótica, encontrada // juntamente com outros numa // escavação junto da Portela do // Outeiro. Caracteriza-se pela sua for-//ma oval e natureza geolo-// gica, inteiramente estranha // à região. C. Ramalho…
