United KingdomA new study suggests that a prehistoric form of the plague may have contributed to a significant population decline during the late Neolithic period in Europe, approximately 5,600 to 4,000 years ago. Researchers identified plague DNA in human remains from this era, indicating that early strains of the bacterium Yersinia pestis existed. These ancient strains lacked a gene that enables modern plague bacteria to spread via fleas, suggesting they might have been transmitted differently. While the connection between these infections and the population drop is still debated, evidence from Lake Baikal in Siberia shows that similar plague outbreaks caused mass deaths among prehistoric hunter-gatherers. This raises questions about the role of infectious diseases in shaping prehistoric human societies.
Bias read (Center): The article presents scientific research on prehistoric plague and its potential impact on population dynamics. It does not take a stance on political issues, nor does it frame the information in a biased manner. The content focuses on historical and biological data rather than contemporary politics
Why these scores (Factual 85 · Objective 70): Factuality is high as the article references genetic differences between prehistoric and Black Death plague strains, aligning with primary sources. Objectivity is lower due to speculative language about 'major inferred population slump' and emphasis on debate without presenting multiple viewpoints.
