Ancient Plague May Have Triggered a 500-Year Population Drop in Neolithic Europe

New genomic and archaeological evidence shows prehistoric Yersinia pestis infected Neolithic farmers in Europe, but ancient strains lacked flea-adaptation genes and outbreaks were scattered without clear mass mortality, leaving open whether plague caused the roughly 500-year population decline in late Neolithic Europe or if other factors were involved.

Ancient DNA traces found on cave walls, hinting at forgotten visitors

A Nature Communications study shows ancient human DNA can persist on cave walls for millennia, with five of 54 samples from 24 rock-art panels testing positive for human DNA. DNA was found on both painted and unpainted surfaces, as well as calcite crusts, suggesting direct deposition or sediment transport rather than solely artwork-related material. Two Covarón Cave samples yielded nuclear DNA linked to Western hunter-gatherers, while others contained both human and animal DNA; a bird-bone airbrush from Altamira yielded no ancient DNA due to modern contamination. The findings indicate cave walls can preserve traces of past visitors long after artworks were made, though preservation varies with mineral crusts and cave conditions. Researchers plan broader testing across more caves and styles to better understand who used caves and when.

Ancient human DNA preserved on Iberian cave walls reshapes prehistoric study

A multinational team led by Hipólito Collado recovered human DNA over 2,000 years old from cave-wall surfaces in Spain and Portugal, showing rock surfaces can preserve genetic material and enabling archaeogenetic study of prehistoric populations. Analyzed 24 rock-art panels across 11 caves (including Escoural and Covarón); the findings, published in Nature Communications as part of the First Art project, suggest caves could act as biological archives for ancient humans.

Shroud of Turin DNA: Plant Traces Suggest Post-1492 Contamination

Researchers analyzing dust and fibers from the Shroud of Turin report plant DNA—carrot, bread wheat and other crops—signalling contamination over time rather than confirming the relic’s age; they caution metagenomics can’t reliably date the cloth, even as radiocarbon dating in 1988 placed it medieval (1260–1390 AD) and 2024 WAXS results broadly align with a two-millennium history.
