Event Overview
Recent scientific discoveries, particularly from ancient teeth found in Siberia, have pushed back the timeline of plague outbreaks by approximately 200 years, with evidence now dating back about 5,500 years ago. This finding is significant as it predates the infamous Black Death, which devastated Europe in the 14th century, by thousands of years. The plague, caused by the bacterium Yersinia pestis, has a long and devastating history of sickening humans. While the Black Death remains the most well-known and catastrophic event associated with the disease, these new findings indicate its presence and impact on human populations much earlier than previously understood. The plague, though rare today, is still a concern for public health, making the study of its ancient origins crucial for understanding its evolution and potential future threats.
