Neanderthals used dental drilling 59,000 years ago

🔑 Enhanced Key Takeaways

•The discovery was made on a Neanderthal molar (Chagyrskaya 64) unearthed from Chagyrskaya Cave in the Altai Mountains of Siberia, Russia.
•Microscopic analysis, including scanning electron microscopy and microtomography, confirmed that the deep hole in the tooth was intentionally drilled by a sharp stone tool, likely twirled between the fingers.
•This evidence of invasive dental treatment by Neanderthals predates the earliest known similar procedures by Homo sapiens by more than 40,000 years.
•The same Neanderthal individual also showed evidence of using toothpicks, indicating a broader understanding of oral hygiene and pain management beyond just drilling.

**Location of Discovery:** Chagyrskaya Cave, Altai Mountains, southwestern Siberia, Russia.
**Specimen:** A 59,000-year-old Neanderthal molar, identified as "Chagyrskaya 64".
**Procedure Identified:** Drilling of a deep hole from the chewing surface of the molar into the pulp cavity.
**Tools Used:** A sharp, thin stone tool, likely manipulated with precise finger movements (twirled between fingertips).
**Purpose:** To remove infected tissue (decaying enamel and inner tooth material) and alleviate pain caused by a carious lesion (cavity).
**Analytical Methods:** Microscopic analysis (including scanning electron microscopy and microtomography) of the tooth's surface revealed parallel linear scratch marks and V-shaped grooves.
**Experimental Replication:** Researchers conducted experiments by manually drilling into modern human teeth with prehistoric-style stone tools to replicate the observed marks and confirm the feasibility of the procedure.
**Associated Findings:** The tooth also exhibited a groove consistent with the use of wooden toothpicks, suggesting additional methods for pain relief and oral hygiene.

🔮 Future ImplicationsAI analysis grounded in cited sources

This discovery will further dismantle the outdated stereotype of Neanderthals as cognitively inferior.

The evidence of complex dental drilling demonstrates sophisticated cognitive abilities, planning, precise motor skills, and deliberate medical strategy, challenging previous assumptions about their intelligence.

The timeline for the evolution of medical intervention and pain management in hominids will be significantly re-evaluated.

The ability to diagnose the source of pain and perform invasive treatment pushes back the known origins of such complex medical behaviors by tens of thousands of years.
