Early Plague Discovered in Ancient Siberian Graves

Scientists have uncovered the oldest evidence of one of humanity’s most deadly pathogens, revealing that the origins of the plague stretch back at least 5,500 years. In the remains of ancient Siberian hunter-gatherers, DNA associated with Yersinia pestis—causing the plague—has been identified, shedding light on a historical health crisis that would later reshape the continent. The findings challenge prior assumptions about the bacteria’s origins, suggesting it was already a significant threat in early human societies. Researchers emphasize the importance of these discoveries in understanding the long-term impact of infectious diseases. These insights also highlight the persistence of plague DNA thousands of years after infection, even in preserved dental remains. Notably, the pathogen’s reliance on fleas for transmission underscores how human and animal activities may have facilitated its spread across vast regions. Despite initial uncertainties, the study provides a critical perspective on the ancient roots of pandemics that shaped human history.
