HUResearchers have made a groundbreaking discovery by identifying ancient human DNA on the walls of caves, marking a new era in archaeology. Previously, scientists could only extract genetic material from fossils such as bones, teeth, or sediment found on cave floors. This new method allows them to analyze DNA directly from the rock surfaces, which had been thought to preserve traces of human contact for thousands of years. The findings challenge previous assumptions about how and where ancient genetic information can be retrieved, opening up new possibilities for studying prehistoric human activity. The study was conducted by an international research team, and the results suggest that cave walls may hold valuable biological data about early humans.
