  • Neanderthals Likely Conducted Dental Surgery 60,000 Years Ago

    Neanderthals Likely Conducted Dental Surgery 60,000 Years Ago

    A new discovery suggests that Neanderthals might have performed dental procedures nearly 60,000 years ago. Scientists analyzed an ancient molar found in Siberia’s Chagyrskaya Cave, revealing evidence that these early humans likely used sharp stone tools to drill into a painful cavity, making it the oldest known example of dental treatment.

    Published in PLOS One, the study was led by researcher Alisa Zubova from Russia’s Peter the Great Museum of Anthropology and Ethnography. The molar belonged to a Neanderthal who lived approximately 59,000 years ago. At its center, scientists identified a deep hole that extended into the pulp cavity—the soft tissue inside the tooth that contains nerves and blood vessels.

    Initially, the shape of the hole puzzled researchers. It didn’t resemble typical tooth decay or natural damage. Under microscopic examination, they observed distinct scratches inside the cavity, indicating the hole was deliberately made rather than resulting from accidental damage.

    To explore further, scientists performed experiments on modern human teeth using sharp stone points similar to tools recovered from the same cave. The patterns and grooves produced during these experiments closely matched the microscopic marks inside the Neanderthal molar.

    The evidence suggests that the Neanderthal may have experienced a severe cavity or infection and used the stone tools to remove infected tissue, likely alleviating pain. Although such an invasive procedure would have been extremely painful, it could have provided lasting relief. The wear marks on the tooth also indicate the individual survived the treatment and continued to use the tooth afterward.

    This finding highlights a surprising level of medical knowledge among Neanderthals. It shows they could identify sources of pain, understand how to treat them, and skillfully manipulate tools for medical procedures. Performing such work would have required patience and resilience from the patient.

    While previous evidence has shown that Neanderthals used toothpicks and possibly medicinal plants, this is the first clear indication that they conducted direct dental interventions. The discovery redefines ideas about Neanderthal intelligence and everyday life, revealing that they may have possessed practical medical skills far earlier than previously thought.

    Researchers conclude that this finding pushes back the history of dental treatment by more than 40,000 years and suggests that complex healthcare behaviors were not exclusive to modern humans.

    Neanderthals, our ancient human relatives, might have been more advanced in health practices than previously believed. A recent study indicates they could have used a sticky substance called birch tar not only for crafting tools but also for wound care and infection prevention.

    Birch tar is a dark, glue-like substance produced by heating birch bark. Archaeologists often find it at Neanderthal sites, traditionally thought to be used mainly as an adhesive for tools. However, scientists now consider that it might have served additional purposes, particularly in medicine.

    The new research, published in the journal PLOS One, was led by Tjaark Siemssen along with teams from the University of Cologne in Germany and the University of Oxford in the UK. Their goal was to determine whether birch tar could have had antibacterial properties that helped curb infections.

    To explore this, researchers replicated how Neanderthals might have produced birch tar thousands of years ago. They used similar birch bark and experimented with simple methods such as heating the bark in clay pits or allowing tar to gather on stone surfaces—techniques accessible without advanced tools. These methods suggest that Neanderthals could have easily made birch tar using readily available resources.

    Once they produced the tar, the team tested it against bacteria, including a common pathogen called Staphylococcus, which causes wound infections. The results showed that all the birch tar samples significantly slowed bacterial growth, indicating that the substance functioned as a natural antibacterial agent.

    This discovery resonates with traditional practices observed among Indigenous communities in northern Europe and Canada, where birch tar has been used for centuries to treat wounds. The study supports the idea that Neanderthals might have independently discovered these medicinal benefits.

    The researchers propose that birch tar could have served multiple purposes for Neanderthals—from repairing tools to treating injuries and preventing infections. Its potential role as an insect repellent adds even more to its versatility, providing additional protection in tough environments.

    These findings contribute to the growing view that Neanderthals were capable of complex thought and innovation. They likely understood how to utilize natural materials around them to enhance their health and increase their chances of survival.

    Furthermore, the study connects to modern scientific pursuits. With antibiotic resistance becoming an urgent global issue, researchers are revisiting natural substances for new treatments. Investigating ancient practices, a field sometimes called “paleopharmacology,” may reveal useful remedies that have been overlooked for centuries.

    Producing birch tar was a labor-intensive, messy process involving fire and sticky materials. The researchers experienced firsthand how difficult it was to handle the substance—especially when cleaning tar off their hands—highlighting the skill and knowledge Neanderthals may have possessed.

    Overall, this research paints a richer picture of Neanderthal life. Far from being merely tool users, they might have been early healers who harnessed natural resources to safeguard their health long before modern medicine existed.
