The Caribbean & Mesoamerica Biogeochemical Isotope Overview (CAMBIO) is an archaeological data community designed to integrate published biogeochemical data from the Caribbean, Mesoamerica, and southern Central America to address questions about dynamic interactions among humans, animals, and the environment in the region over the past 10,000 years. Here we present the CAMBIO human dataset, which consists of more than 16,000 isotopic measurements from human skeletal tissue samples (δC, δN, δS, δO, Sr/Sr, Pb, Pb, Pb, Pb) from 290 archaeological sites dating between 7000 BC to modern times. The open-access dataset also includes detailed chronological, contextual, and laboratory/sample preparation information for each measurement.

Article Synopsis
  • Researchers analyzed genomes from 33 Ashkenazi Jews dating back to the 14th century, found in a medieval cemetery in Erfurt, Germany, revealing genetic links to modern Ashkenazi Jews (AJ).
  • The Erfurt individuals displayed greater genetic variability in Eastern European ancestry compared to contemporary AJ and carried specific mitochondrial lineages and pathogenic variants seen in modern AJ.
  • Findings indicate that the medieval Erfurt community underwent a significant population bottleneck, suggesting that the development of the AJ population's genetic structure began before the 14th century and included more diversity than is present in modern AJ.

Maize is a cultigen of global economic importance, but when it first became a staple grain in the Americas, was unknown and contested. Here, we report direct isotopic dietary evidence from 52 radiocarbon-dated human skeletons from two remarkably well-preserved rock-shelter contexts in the Maya Mountains of Belize spanning the past 10,000 years. Individuals dating before ~4700 calendar years before present (cal B.
