Etched into the limestone walls of ancient caves in Spain and Portugal, human DNA has waited thousands of years to be heard. Researchers from the First Art project, working alongside the Max Planck Institute for Evolutionary Anthropology, discovered that genetic material deposited through touch, breath, and bodily presence can survive on cave surfaces across millennia — offering archaeology a new kind of witness. The finding suggests that the walls themselves, long regarded as mere canvases, are also archives of the people who stood before them, and that the story of prehistoric humanity may b
