Article Synopsis
- Sambaqui societies, existing from 8,000 to 1,000 years ago along the Atlantic coast of South America, represent a unique archaeological phenomenon that is still poorly understood in terms of their origins and evolution.
- Research involving genome-wide data from 34 ancient individuals found that early Holocene hunter-gatherers did not show genetic ties to later populations, indicating minimal contribution to coastal groups.
- The study revealed genetic diversity among different Sambaqui communities, suggesting a more complex history of interaction between inland farmers and coastal societies than what is reflected in the archaeological records.
Sex estimation is an important procedure in forensic anthropology for human identification. The development of new technologies, such as three-dimensional computed tomography (CT), has provided excellent alternatives for this purpose. This study examined and compared a morphological method for sex estimation using two different approaches - direct measurement of physical structures and tomographic analysis using 3D images.

- Zinc isotope ratios in dental enamel are an emerging tool for dietary studies in archaeology, but concerns exist regarding contamination from gloves.
- A study examined how nitrile and latex gloves may affect Zn isotope ratios during enamel sampling from early Holocene hunter-gatherers in Brazil.
- The research found that while gloves can release Zn, significant contamination did not occur during sampling, and variability in Zn isotopes was mostly linked to the developmental stage of the teeth rather than glove use; further investigation into Zn isotopes as a breastfeeding indicator is needed.
We present here evidence for an early Holocene case of decapitation in the New World (Burial 26), found in the rock shelter of Lapa do Santo in 2007. Lapa do Santo is an archaeological site located in the Lagoa Santa karst in east-central Brazil with evidence of human occupation dating as far back as 11.7-12.
