A 42,000-year-old tooth changed everything. Researchers at the University of Toulouse sequenced DNA from a Neanderthal found at Grotte Mandrin in France's Rhône Valley, and what…

The tooth came from Grotte Mandrin, a site in the Rhône Valley that's been a goldmine for archaeologists studying ancient human activity.

What the genome showed was isolation. Deep, sustained isolation. Thorin's group had been genetically separate from nearby Neanderthal populations for approximately 50,000 years.

Slimak's work at the University of Toulouse has long pushed toward combining hard archaeological evidence with genetic analysis, and Thorin's case is probably the clearest…

The dominant narrative for years was pretty straightforward: Neanderthals faded out because they got absorbed into expanding modern human populations.

9 / 15

Thorin's group didn't mix. They were geographically close to other populations — both Neanderthal and early modern human — but closeness didn't mean contact, at least not genetic…

The isolation Thorin's group maintained raises uncomfortable questions about how extinction actually worked for Neanderthals.

Researchers aren't done. Ongoing excavations continue to pull artifacts and bone fragments from the site, and each one adds detail to a picture that's still being assembled.

The implications stretch beyond Neanderthals specifically. If small, genetically closed groups could persist undetected within a broader landscape of populations — maintaining…
