Plague DNA found in 5,500-year-old skeletons rewrites human history

Researchers have uncovered evidence that the plague, caused by *Yersinia pestis*, was a deadly threat to early humans far earlier than previously believed, after isolating bacterial DNA from 5,500-year-old skeletal remains of Siberian hunter-gatherers. The discovery, reported on Sunday, 21 June 2026, pushes back the timeline of the plague’s lethal impact to the dawn of human civilization, challenging long-held assumptions about the disease’s historical reach.
Genetic analysis of the skeletal material, excavated from burial sites in Siberia, confirmed the presence of *Y. pestis* DNA, demonstrating that the bacterium was already circulating among human populations millennia before the first recorded pandemics. “We must accept what the data shows,” stated the research team, whose findings were published by Czech broadcaster iROZHLAS . The study suggests that the plague may have contributed to population declines or societal shifts in prehistoric communities, though the exact mechanisms of transmission and mortality rates remain subjects for further investigation.
The revelation comes as archaeologists also announced the discovery of a 5,000-year-old precursor to Stonehenge in the Netherlands, consisting of two wooden posts that may have been used to track solar movements. The find, reported by Dutch news outlet NU.nl, underscores the sophistication of Neolithic engineering and astronomical knowledge .
Meanwhile, in a separate but equally striking discovery, a 2,300-year-old Scythian boot, preserved in the frozen Altai Mountains, has been put on display at the State Hermitage Museum in St. Petersburg. The artifact, dating to the Iron Age, offers rare insight into the craftsmanship and nomadic lifestyle of the Scythians, a people whose influence stretched across modern-day Russia, Mongolia, China, and Kazakhstan .
In a parallel development, researchers have deciphered the ancient origins of the Euphrates River, tracing its formation to a pivotal role in the rise of early civilizations such as Uruk and Babylon. The river’s fertile basin, shared with the Tigris, served as one of humanity’s first cradles of agriculture and urbanization, according to findings published by the *Cyprus Mail* .
These discoveries collectively reshape our understanding of early human resilience, innovation, and vulnerability. While the plague’s earlier-than-expected presence raises new questions about prehistoric health crises, the unearthing of Stonehenge’s precursor and the Scythian boot highlights the enduring legacy of ancient cultures. As scientists continue to probe the past, each revelation adds a layer to the complex mosaic of human history.
