Story

The narrative of this ancient life

The Sambaqui Culture, specifically related to the Jabuticabeira II archaeological site, represents a fascinating and complex society that thrived along the coastlines of what is now Brazil during the Pre-Columbian era. This culture is characterized by its unique mortuary practices, social organization, and subsistence strategies which are vividly depicted through extensive archaeological studies.

Geographic and Chronological Context:

The Jabuticabeira II site, part of the broader Sambaqui Culture, is located in the southern coastal region of Brazil, particularly in the state of Santa Catarina. Sambaquis, or shell mounds, are the hallmark of this culture, consisting of large accumulations of shells, fish bones, and other materials. These mounds were constructed over thousands of years, with the Jabuticabeira II site being radiocarbon dated to between 2500 and 1200 years before present (BP), defining it as a mid to late Holocene community.

Environmental Adaptation:

The people of the Sambaqui Culture were adept at utilizing the coastal environment in which they lived. They primarily subsisted on marine resources, including fish, mollusks, and crustaceans, as evidenced by the abundant remains found within the shell mounds. However, they were not solely reliant on the sea; archaeological findings indicate they also hunted terrestrial animals and gathered plant resources, showcasing a high level of adaptation to their diverse ecological surroundings.

Social and Cultural Practices:

Sambaqui societies were complex and are believed to have had a sophisticated social structure. This is primarily inferred from their burial practices. The Jabuticabeira II site contains numerous human burials, often richly adorned with grave goods such as stone tools, ornaments, and ochre, suggesting a community with social stratification and believed to have ritual significance. The attention given to these burials indicates a society with spiritual or religious beliefs, possibly involving ancestor worship or a form of early shamanism.

Economic Activities:

While the Sambaqui Culture is often associated with shellfish gathering and fishing, evidence suggests that they engaged in broader economic activities. Tool-making was an essential skill, with polished stone and bone tools being prevalent. These tools reflect a society that valued craftsmanship and efficiency in activities such as hunting, weaving, and wood-working. Trade routes may have existed, given the presence of non-local materials, indicating they interacted and possibly exchanged goods with inland groups.

Cultural Legacy and Influence:

Xingu cultures, representing some of the early complex societies in South America. The Sambaqui Culture, like its contemporaries, played a role in shaping the historical trajectory of indigenous societies in the region.

In conclusion, the Sambaqui Culture of Jabuticabeira II presents a rich tapestry of archaeological insight into a sophisticated coastal society of Pre-Columbian Brazil. Through their material remains, we gather knowledge about their complex social hierarchy, environmental adaptation, and cultural practices, painting a detailed picture of their daily lives and spiritual world.

Abstract

Sambaqui (shellmound) societies are among the most intriguing archaeological phenomena in pre-colonial South America, extending from approximately 8,000 to 1,000 years before present (yr BP) across 3,000 km on the Atlantic coast. However, little is known about their connection to early Holocene hunter-gatherers, how this may have contributed to different historical pathways and the processes through which late Holocene ceramists came to rule the coast shortly before European contact. To contribute to our understanding of the population history of indigenous societies on the eastern coast of South America, we produced genome-wide data from 34 ancient individuals as early as 10,000 yr BP from four different regions in Brazil. Early Holocene hunter-gatherers were found to lack shared genetic drift among themselves and with later populations from eastern South America, suggesting that they derived from a common radiation and did not contribute substantially to later coastal groups. Our analyses show genetic heterogeneity among contemporaneous Sambaqui groups from the southeastern and southern Brazilian coast, contrary to the similarity expressed in the archaeological record. The complex history of intercultural contact between inland horticulturists and coastal populations becomes genetically evident during the final horizon of Sambaqui societies, from around 2,200 yr BP, corroborating evidence of cultural change.
