Quick answers

Where were the plague victims discovered?

The victims were hunter-gatherers found in cemeteries near Lake Baikal in Siberia.

How was the plague identified in these ancient remains?

The identification was made through the analysis of ancient DNA, specifically from ancient teeth.

How does this discovery change the known timeline of the plague?

It sets back the date of the earliest known outbreak to over 5,500 years ago, predating the Black Death by nearly 5,000 years.

The brief

Evidence from ancient teeth and graves in Siberia indicates that plague outbreaks killed hunter-gatherers near Lake Baikal more than five millennia ago. This discovery identifies these individuals, including children, as the earliest known victims of the disease.

Coverage from Nature, the Smithsonian, and the New York Times emphasizes that these findings rewrite the plague's history, placing the outbreaks nearly 5,000 years before the Black Death. Outlets including AP News and ScienceDaily highlight the role of ancient DNA in uncovering this timeline.

Future attention remains on how this evidence informs the origins of the Black Death, which Global News reports was a complete surprise to experts.
