El hacha de jadeíta de Portela do Outeiro (Sertã, Castelo Branco, Portugal)
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…
The population genomics of archaeological transition in west Iberia: Investigation of ancient substructure using imputation and haplotype-based methods
We analyse new genomic data (0.05–2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200–3500 BC) to the Middle Bronze Age (1740–1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a significant degree of local hunter-gatherer contribution to later Iberian Neolithic populations. A more subtle genetic influx is also apparent in the Bronze Age, detectable from analyses including haplotype sharing with both ancient and modern genomes, D-statistics and Y-chromosome lineages. However, t…
