Methods and ancient-genomics: radiocarbon re-dating and robust aDNA
Key Questions
What new dating and analysis methods are highlighted in recent ancient genomics research?
The highlight covers AI-assisted dating of Herculaneum scrolls, OSL dating of Roman gold mines, and digital metrology for Jerusalem bullae using fingerprints and geochemistry. Additional techniques include XRD/metabolomics, SfM/GPR, and paleonutrition synthesis via stable isotopes, aDNA, and paleoproteomics to challenge simplistic ancestral diet narratives.
How is LiDAR technology being applied in archaeological surveys?
LiDAR is used with geomorphological analysis in regions like Scotland, Uzbekistan, and the Sahara to map sites. It also supports spatial modeling in a documentary reinterpreting ancient capitals such as Angkor, Great Zimbabwe, Cahokia, and Machu Picchu as ceremonial centers rather than dense residential areas.
What does microbiome research on Ötzi the Iceman reveal about ancient preservation?
Studies of Ötzi’s 5,300-year-old body identify cold-tolerant yeast and unexpected microbes that may have fed on chemicals used in preservation. This adds to ancient genomics methods discussed in the highlight, including robust aDNA analysis.
AI dating, Herculaneum scrolls, Linear Elamite; LiDAR (Scotland/Uzbek/Sahara, geomorphological analysis); Atbai satellite burials (260 monuments); XRD/metabolomics; SfM/GPR; critique hype. New: OSL dating of Roman gold mines (Pyrenees). New: digital metrology and provenance analysis of Jerusalem bullae (fingerprints, geochemistry). New: Maya glyph guide (mayaglyphs.org) as a free epigraphy resource. New: Paleonutrition synthesis using stable isotopes, aDNA, paleoproteomics – challenges 'one ancestral diet' myth, adds methodological depth. A popular video on the Library of Alexandria and Herculaneum scrolls with AI reading adds context to the scrolls story. New: Documentary 'Ancient Capitals Weren’t Built to Hold Crowds' uses LiDAR, spatial modeling, and refuse analysis to reinterpret Angkor, Great Zimbabwe, Cahokia, and Machu Picchu as ceremonial/administrative centers, not dense residential hubs – adds conceptual depth to urbanism studies.
