Techniques developed to study the distant past—from dating ancient artifacts to reconstructing climate records in ice cores—are now being repurposed to better understand the lives of modern sea turtles. Using radiocarbon methods from archaeology, researchers show that sea turtle shell plates are biological time capsules that record signs of major environmental disturbances in the ocean.
An international team of archaeologist has uncovered the earliest known clay ornaments in Southwest Asia, revealing a forgotten chapter in the story of how humans began to express identity, belonging, and meaning through material culture. The findings, published this week in Science Advances, push back the symbolic use of clay in the region by thousands of years.
A new interdisciplinary study published in Nature reconstructs over 2,000 years of population history in Argentina’s Uspallata Valley (UV), a southern frontier of Andean farming spread in ancient times, with broader lessons on how agriculture shaped societies and how communities endured crises. By combining ancient human and pathogen genomics with isotopic analyses, archaeology and paleoclimate records–and working in close collaboration with Huarpe Indigenous communities–, the research reveals how local hunter-gatherers adopted agriculture, how more recent intensive maize farmers experienced prolonged stress, and how kinship-based mobility may have helped communities persist through instability.
Researchers from the University of Seville are participating in an international study that sheds new light on the genetic diversity of Andalusian society between the 8th and 11th centuries AD and reinforces the historical significance of the dolmen as a sacred space used throughout the ages
