Neanderthal tooth from Siberian cave shows signs of earliest-known invasive dental surgery - study

A remarkable discovery from Russia's Chagyrskaya Cave is rewriting our understanding of Neanderthal capabilities. Archaeologists have unearthed a Neanderthal molar, dating back around 59,000 years, that bears clear evidence of invasive dental surgery. This ancient molar shows signs of a deep cavity and deliberate work with a small stone tool to remove decay, suggesting a Neanderthal individual sought relief from severe toothache.

The implications of this find are profound. It demonstrates that Neanderthals possessed sophisticated cognitive abilities, including planning, precise motor skills, and a deliberate medical strategy. This directly challenges the long-held, outdated view that such complex behaviors were solely the domain of Homo sapiens. The procedure required diagnosing the problem, understanding the potential for relief through intervention, selecting the right tool, and executing the task with controlled movements.

This is important because it proves Neanderthals possessed sophisticated cognitive abilities, including planning, precise motor skills and deliberate medical strategy, challenging the outdated view that such complex behavior was exclusive to modern humans.

This discovery, published in PLOS One by researchers from the Institute of Archaeology and Ethnography of the Siberian Branch of the Russian Academy of Sciences, underscores the advanced technical skills and cognitive prowess of our extinct close relatives. It adds to a growing body of evidence suggesting Neanderthals were far more capable than previously assumed, blurring the lines between them and modern humans in terms of intellectual and practical abilities.

The procedure required diagnosing the source of pain, understanding that removing decayed tissue could bring relief, deliberately selecting an appropriate stone tool and executing precise drilling with controlled finger movements.
