A recent study led by researchers from the Russian Academy of Sciences has revealed what could be the earliest known evidence of dental procedures, suggesting that Neanderthals conducted such treatments around 59,000 years ago. This finding, centered on a molar discovered in Chagyrskaya Cave, Siberia, Russia, indicates that the tooth had a deep hole likely created by drilling with a sharp stone tool to remove infected tissue. This discovery predates the previously oldest known dental treatment, which was from a human specimen in Italy dating back about 14,000 years. The researchers used advanced microtomography imaging to identify microscopic grooves consistent with deliberate drilling, rather than natural wear. Experiments using replica stone tools confirmed that similar patterns could be reproduced on modern human teeth, suggesting a high level of technical skill was involved in the procedure. The study implies that Neanderthals were more socially and intellectually advanced than previously thought, as they likely cared for injured individuals and understood the benefits of dental treatment. Lead researcher Dr. Aliza Zubova emphasized the significance of this finding in reshaping our understanding of Neanderthal capabilities.
