Two sixth - century skeleton in the closet are giving some huge insights into the murky and roughshod history of the bacterium behind the Black Death .
A squad of bioarchaeologists analyzed sample take from the skeletons discovered in Altenerding , an ancient southern German burial site near Munich , who snuff it of the Plague of Justinian . Using “ molecular hint ” from the victims and the first high - reporting genome of the bacterium , they showed that the Justinian pest was make by the same bacterium , Yersinia pestis , as the bubonic plague , or Black Death , that rampaged across Europe in the 14th C .
However , they found many genetic difference between the two strains , despite being the same specie . The sequencing demo 30 new identify mutations and morphological rearrangements unique to the Justinianic breed . It ’s believed these mutation could be linked to the virulency ofY. pestis . This uncovering is also revealing newfangled information about the molecular evolution ofY. pestisand its upshot on human history .

The Plague of Justinian swept through the Byzantine Empire in 541 CE , taking with it the lives of as many as 50 million masses – around 15 pct of the world ’s population . Some 800 years afterward , the Black Death sweep through Europe and lead out around 60 percent of the population . The two pest have been linked before , but it was never clear just how like or unlike the var. were to each other .
" Our inquiry confirms that the Justinianic plague reached far beyond the historically documented affected part and provides newfangled insights into the evolutionary history of Yersinia pestis , exemplify the potential of ancient genomic reconstructions to broaden our understanding of pathogen evolution and of historical events , " inquiry fellow worker Michal Feldman said in astatement . " Our reanalysis of old datasets stresses the grandness of following strict measure to avoid errors in the Reconstruction Period of ancient pathogen genome . "
