- The genetic history of Portugal over the past 5,000 years.Publication . Roca-Rada, Xavier; Davidson, Roberta; Williams, Matthew P.; Villalba-Mouco, Vanessa; Carvalho, António Manuel Faustino de; Ravishankar, Shyamsundar; Collen, Evelyn; Haarkötter, Christian; Taufik, Leonard; Cuesta-Aguirre, Daniel R.; Tente, Catarina; Calleja, Álvaro M Monge; MacRoberts, Rebecca Anne; Melo, Linda; Purnomo, Gludhug A.; Souilmi, Yassine; Tobler, Raymond; Cunha, Eugénia; Tereso, Sofia; Matos, Vítor M. J.; Fernandes, Teresa Matos; Maurer, Anne-France; Silva, Ana Maria; Carvalho, Pedro C.; Llamas, Bastien; Teixeira, João C.Recent ancient DNA studies uncovering large-scale demographic events in Iberia have presented very limited data for Portugal, a country located at the westernmost edge of continental Eurasia. Here, we present the most comprehensive collection of Portuguese ancient genome-wide data, from 67 individuals spanning 5000 years of human history, from the Neolithic to the nineteenth century. We identify early admixture between local hunter-gatherers and Anatolian-related farmers in Neolithic Portugal, with a northeastern-southwestern gradient of increasing Magdalenian-associated ancestry persistence in Iberia. This profile continues into the Chalcolithic, though Bell Beaker-associated sites reveal Portugal's first evidence of Steppe-related ancestry. Such ancestry has a broader demographic impact during the Bronze Age, despite continuity of local Chalcolithic genetic ancestry and limited Mediterranean connections. The village of Idanha-a-Velha emerges in the Roman period as a site of significant migration and interaction, presenting a notably diverse genetic profile that includes North African and Eastern Mediterranean ancestries. The Early Medieval period is marked by the arrival of Central European genetic diversity, likely linked to migrations of Germanic tribes, adding to coeval local, African, and Mediterranean influences. The Islamic and Christian Conquest periods show strong genetic continuity in northern Portugal and significant additional African admixture in the south. The latter remains stable during the post-Islamic period, suggesting enduring African influences. We reveal dynamic patterns of migration in line with cultural exchange across millennia, but also the persistence of local ancestries. Our findings integrate genetic information with historical and archeological data, enhancing our understanding of Iberia's biological and cultural heritage.
- The “Ferradeira” individual burial of Herdade do Álamo (Beja): facets of social change in the late 3rd millennium BC in South PortugalPublication . Valera, António Carlos; do Pereiro, Tiago; Nogueira, Sofia; Evangelista, Lucy; Maurer, Anne-France; Barrocas Dias, Cristina; Ribeiro, Sara; Bottaini, CarloThe individual burial of the Herdade do Alamo, located in Beja municipality, South Portugal, is presented along with its bioanthropological study, radiocarbon dating and isotopic approaches on diet and mobility. The results show a male, with a terrestrial diet and youth mobility, dating from the last quarter of the 3rd millennium BC. The archaeometallurgical study of the metal votive assemblage (one tongue dagger and three Palmela points) indicates a copper metallurgy with high values of Arsenic (As), typical of this period of transition. The burial is contextualized in a process of individuation of the funerary practices and in the "Ferradeira Horizon", considered as a facet of the diversified funerary practices and of the complex social changes of the late 3rd millennium BC in the South of Portugal.
