Scientists in Siberia's Chagyrskaya Cave discovered a 60,000-year-old Neanderthal tooth showing evidence of advanced dental surgery. Microscopic analysis revealed a precise 4.2mm wide drill hole, similar to modern root canal treatments, performed using stone tools. The research indicates the patient survived for years after the procedure, as evidenced by wear patterns from chewing. This discovery challenges the belief that modern humans invented dentistry 14,000 years ago, proving Neanderthals were technologically advanced and possessed medical knowledge far earlier than previously thought. https://beauronews.com/news.php?id=scientists-stunned-by-discovery-in-siberia-regarding-dental-surgery-622835 #creator program
