The Black Death, that has killed 60 percent of Europe’s population in the 14th century, quickly throughout the continent. Researchers at the Max Planck Institute of the Science of Human History in Jena Germany, analyzed 34 ancient genomes of the lethal Yersinia pestis bacterium to slender that exactly how the plague came to Europe. They hoped to pinpoint whether it had a single source or was brought to the continent by travelers from the various parts of the world.
Their findings, revealed in the journal Nature Communications, present that the earliest evidence of the illness is from Laishevo, in Russia’s Volga region. According to the study, it was that researchers discovered the pressure of the bacteria that was ancestral to all the other genomes that they analyzed.
These findings show a single entry of Y. Pestis into Europe through the east,” as said by archaeogeneticist Maria Spyrou, from the Max Planck Institute of the Science of Human History. Once the plague made it to Europe, scientists say, a single strain was responsible for the Black Death, stretching from Italy to the UK.
Nonetheless, as Science Journal reports, in Russia, the Volga region was not necessarily ground for the plague since it could have originated in the parts of western Asia, where scientists have not sampled the DNA of Y. Pestis. “We have shown that extensive analysis of historical Y. pestis genomes can present distinctive insights into the microevolution of a pathogen over several hundred years”, stated senior creator Johannes Krause, Director of the Division of Archaeogenetics on the Max Planck Institute of the Science of Human Historical past.
