Neanderthals likely created ancient hand stencils in Spain before modern humans arrived

New research suggests that Neanderthals, not modern humans, likely created iconic hand stencils found in caves, particularly in Maltravieso cave, Spain. These stencils date back at least 66,700 years, predating modern humans in the region. Using advanced uranium-thorium dating techniques, scientists determined the minimum ages of 22 samples from the stencils. The findings indicate that some prints were made long before modern humans arrived in Iberia, supporting the idea that Neanderthals were the original artists. The purpose of these ancient hand prints remains uncertain. Researchers believe they may have had a ritualistic function, as they are located deep within caves, away from natural light. The study is published in the Journal of Archaeological Science: Reports.
