A recent study published in PLOS One has uncovered evidence that Neanderthals practiced primitive dentistry, challenging long-held beliefs about their intelligence. Researchers examined a 59,000-year-old molar, known as Chagyrskaya 64, found in the Altai Mountains of Siberia. The tooth exhibited signs of a massive cavity that had been intentionally drilled, likely using a sharp stone tool. The cavity extended into the pulp chamber, indicating that the owner experienced significant pain during the procedure. This discovery suggests that Neanderthals not only understood the concept of pain but also had the capability to perform basic medical treatments on each other. The use of pointed jasper tools found at the site points to a level of planning and tool-making sophistication previously underestimated in Neanderthals. As new studies continue to emerge, they paint a picture of Neanderthals as intelligent beings capable of complex thought and social organization, rather than the brutish stereotype often associated with them. This evolving understanding of Neanderthal capabilities invites a reevaluation of how we perceive their place in human history.
