A pesquisa teve por objetivo compreender os grupos sambaquieiros que ocuparam o Complexo Lagunar de Saquarema entre 6.600-1.500 anos cal AP. Foi construído um modelo onde dois fatores, mudança ambiental e contato intersocietal, influenciaram o processo de transformação sociocultural verificado entre os grupos sambaquieiros. Paralelo às mudanças dos recursos e na prática de edificação dos mounds, observou-se mudança na tecnologia da indústria lítica. Associada a esta mudança tecnológica, novas práticas funerárias também foram introduzidas como a cremação e a manipulação de ossos humanos. Assim, por volta de 2.000 anos cal AP, esse contato, somado a um processo que já vinha se desenvolvendo no interior do sistema, marcou o início do colapso da sociedade sambaquiana no Complexo Lagunar de Saquarema.
The greatest evidence of the pre-colonial presence that occupied the coastal region are archaeological sites called coastal sambaquis. Aiming to identify potential areas for installation of sambaqui groups on the coast of Sergipe and Bahia, it was proposed to use an unusual approach in Brazilian archeology which is to use, as a starting point, an understanding of the evolution of the coastal zone in the last 5600 cal years BP, to guide the archaeological exploration in search of shell mounds sites. The prospecting work carried out resulted in the discovery of archaeological sites of the sambaqui type on the northern coast of Bahia. This study becomes relevant when enabling increase of information concerning its physical environment and the transformations experienced by the coastal zone during the Holocene and their impact on pre-colonial occupation of the region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
