- The Bom Santo Cave (Lisbon, Portugal): catchment, diet, and patterns of mobility of a Middle Neolithic populationPublication . Carvalho, António Faustino; Alves-Cardoso, Francisca; Gonçalves, David; Granja, Raquel; Cardoso, João Luís; Dean, Rebecca M.; Francisco Gibaja, Juan; Masucci, Maria A.; Arroyo-Pardo, Eduardo; Fernández-Domínguez, Eva; Petchey, Fiona; Price, T. Douglas; Mateus, José Eduardo; Queiroz, Paula Fernanda; Callapez, Pedro; Pimenta, Carlos; Regala, Frederico T.The study of the Bom Santo Cave (central Portugal), a Neolithic cemetery, indicates a complex social, palaeoeconomic, and population scenario. With isotope, aDNA, and provenance, analyses of raw materials coupled with stylistic variability of material culture items and palaeogeographical data, light is shed on the territory and social organization of a population dated to 3800-3400 cal BC, i.e. the Middle Neolithic. Results indicate an itinerant farming, segmentary society, where exogamic practices were the norm. Its lifeway may be that of the earliest megalithic builders of the region, but further research is needed to correctly evaluate the degree of this community's participation in such a phenomenon.
- The Mesolithic-Neolithic transition in southern IberiaPublication . Cortes Sanchez, Miguel; Jiménez-Espejo, Francisco J.; Simon Vallejo, Maria D.; Gibaja Bao, Juan; Carvalho, António Faustino; Martinez-Ruiz, Francisca; Rodrigo Gamiz, Marta; Flores, Jose-Abel; Paytan, Adina; Lopez Saez, Jose A.; Pena-Chocarro, Leonor; Carrion, Jose S.; Morales Muniz, Arturo; Rosello Izquierdo, Eufrasia; Riquelme Cantal, Jose A.; Dean, Rebecca M.; Salgueiro, Emilia; Martinez Sanchez, Rafael M.; De la Rubia de Gracia, Juan J.; Lozano Francisco, Maria C.; Vera Pelaez, Jose L.; Llorente Rodriguez, Laura; Bicho, Nuno Gonçalo Viana Pereira FerreiraNew data and a review of historiographic information from Neolithic sites of the Malaga and Algarve coasts (southern Iberian Peninsula) and from the Maghreb (North Africa) reveal the existence of a Neolithic settlement at least from 7.5 cal ka BP. The agricultural and pastoralist food producing economy of that population rapidly replaced the coastal economies of the Mesolithic populations. The timing of this population and economic turnover coincided with major changes in the continental and marine ecosystems, including upwelling intensity, sea-level changes and increased aridity in the Sahara and along the Iberian coast. These changes likely impacted the subsistence strategies of the Mesolithic populations along the Iberian seascapes and resulted in abandonments manifested as sedimentary hiatuses in some areas during the Mesolithic-Neolithic transition. The rapid expansion and area of dispersal of the early Neolithic traits suggest the use of marine technology. Different evidences for a Maghrebian origin for the first colonists have been summarized. The recognition of an early North-African Neolithic influence in Southern Iberia and the Maghreb is vital for understanding the appearance and development of the Neolithic in Western Europe. Our review suggests links between climate change, resource allocation, and population turnover. (C) 2011 University of Washington. Published by Elsevier Inc. All rights reserved.
