Archaeologists discovered a 59,000-year-old Neanderthal molar in Siberia featuring a drilled hole used to treat a dental cavity [1].
The discovery suggests that Neanderthals possessed sophisticated medical knowledge and the ability to perform invasive procedures long before previously thought. This finding shifts the timeline of human healthcare by demonstrating that prehistoric hominids could identify and treat specific sources of physical pain.
The specimen was recovered from a cave in the Altai region of Russia [1], [2]. Researchers determined that the hole in the tooth was not a result of natural decay but was intentionally created using a stone tool [4]. This targeted drilling was performed to treat a painful cavity, marking the first known instance of such dental surgery in the archaeological record [3], [5].
This evidence predates previous records of dental surgery by more than 40,000 years [6]. The precision required to drill into a tooth without shattering it indicates a level of technical skill and anatomical understanding previously unattributed to Neanderthals [5].
Ellen Phiddian of ABC Science said the find has implications for how scientists view the cognitive and social capabilities of extinct human species [1]. The research was reported this week on May 13 and 14 [6], [1].
The discovery highlights a capacity for empathy and care, as the procedure would have required a patient to remain still while another individual performed the operation [5]. Such an act implies a social structure capable of supporting medical intervention, a stark contrast to the image of Neanderthals as primitive hunters.
“The discovery suggests that Neanderthals possessed sophisticated medical knowledge.”
This finding challenges the traditional evolutionary narrative that complex medical intervention was a uniquely Homo sapiens trait. By pushing the origins of dentistry back nearly 60,000 years, the discovery suggests that the cognitive ability to diagnose a problem and apply a technical solution was present in other human lineages, potentially altering the understood timeline of human cultural and intellectual development.
