Resumo: Chipped stone tools are the most abundant remains of human presence in prehistory. Their variability and evolution are due to multiple factors. Some of the most important are the availability of raw materials, which bears on the quality of the toolkits given the resources available in the landscape, and human evolution, cognition, technological development, cultural complexity, and social identity. Because of this and given the heavy dependence of humans on stone tools, toolkits changed rapidly when conditions changed, and remained relatively stable when conditions were stable. After a century of investigation, today's laboratory procedures allow researchers to search, find and pinpoint the main features of these tools across vast regions and, within each region, across time, with great confidence. This is done with such precision that it is frequently possible to know the provenance of each raw material, to infer the function of archaeological sites, and to determine for which tasks each stone tool was used. In this entry, we present an overview of these assemblages and their meaning, and up-to-date ways of studying them.2023-11-10T00:00:00ZEarly or Middle Stone Age?

Resumo: Capangombe – Santo António is an open-air site located 596 m a.s.l. at the foothill of Morro Santo António, Namibe Province (southwest Angola). The inselberg of Santo António is associated to the Chela escarpment developing from the Marginal Mountain range parallel to the Atlantic Ocean, separating the Angolan inland plateau from the coastal semi-arid to arid plain. A dissected valley formed by the Leba-Capangombe stream exposed a conglomerate with abundant stone tools assigned to the Early Stone Age (ESA). The site was discovered in 1966 by Miguel Ramos, who collected a total of 1776 lithic artifacts, and further published a small report about the assemblage in 1971. In this preliminary analysis, Ramos focused on cleavers using the “French school” typology for the “hachereaux” in Northern Africa and concluded that there are several morphotypes identified in Capangombe-Santo António with specific features, suggesting the occurrence of a local tradition for the Late ESA/Middle Stone Age (MSA). The study presented here is a new analysis of the lithic assemblage curated at the University of Lisbon, Portugal. A sample of 1017 artefacts was analyzed for this project applying an extended descriptive methodology to characterize lithic raw material procurement, reduction sequences and typological classes. The chrono-cultural model initially proposed for the site is revised thanks to recent advances in Stone Age studies.2023-11-01T00:00:00ZThe Middle Stone Age of Atlantic Africa: A critical reviewPereira, TelmoOosterbeek, LuizPleurdeau, DavidCamara, AbdoulayeBocoum, HamadyThiam, DjibrilAlabi, Raphael A.Kote, LassinaToubga, LassaneBenjamim, Maria HelenaNankela, Almade Matos, Danielahttp://hdl.handle.net/11144/66652023-11-20T12:55:03Z2023-11-01T00:00:00ZTítulo: The Middle Stone Age of Atlantic Africa: A critical review

Resumo: Evidence of early Homo sapiens populations at the Atlantic coast of Africa remains relatively poorly known in relation to other regions of the continent. Nevertheless, available data across the continent provides a good starting point for current and future research investigations. The many sites known, documented and studied contribute in an increasingly way to the global understanding of the human emergence, including evidence of human evolutionary and technological advances, specific adaptations to diverse environments, the diffusion of Homo species and how humans interacted with each other from the “Early Stone Age (ESA)” through to the Middle Stone Age (MSA) from northern and southern Africa to the West. The differences of knowledge between the Atlantic coast in regard to other regions might be attributed to a number of reasons including but not limited to the history of scientific interest, site formation processes or economic, institutional and political constraints. However, the region received a renewed attention and funds that, combined with new methods and techniques, has been allowing an increased training of new researchers and the acquisition of high-resolution archaeological, paleoenvironmental and chronological data. Together, these inputs will reduce the differences of knowledge between the Atlantic coast and the Northern, Southern and Eastern Africa regions. The African Atlantic Coast represents more than 40% of the continent's perimeter, covering all Africa's climate zones, the hot arid environments, mountainous regions, and tropical rainforest could become relevant barriers for human mobility, but the shallow continental platform, and the great number of river basins allowed mobility between north and south coastal biomes into the continental interiors. These may have provided predictable patchy clusters of resources allowing human populations to thrive, enabling greater mobility and consequent diffusion of cultural traits, resources, and DNA. In this paper we review the record about the prehistory, paleoenvironments and paleoanthropological visibility and potentiality of Atlantic Africa.2023-11-01T00:00:00ZTiago Saraiva and Marta Macedo (eds.).

Resumo: The investigations in the book Capital Científica. Práticas da Ciência em Lisboa e a
História Contemporânea de Portugal (Scientific Capital. Practices of Science in Lisbon and
the Contemporary History of Portugal) are the result of two projects conducted over the
past few years at the Instituto de Ciências Sociais and the Centro Interuniversitário de
História das Ciências e da Tecnologia on “The Spaces of Portuguese Technoscience (1837-
1947)” and “The Making of a Technoscientific Capital (1870-1940).” However, the book
can also be read as a synthesis of the advances in the history of science and technology in
Portugal during the last decades. This field of research has been particularly active, and
the book demonstrates the maturity and the great coherence of historiographies in which
the editors have occupied a central position, either in connection with urban history
(Tiago Saraiva), or the history of the construction of the national state (Marta Macedo).2020-06-01T00:00:00Z
