The oldest strain of Yersinia pestis -- the bacteria behind the plague that caused the Black Death, which may have killed as much as half of Europe's population in the 1300s -- has been found in the remains of a 5,000-year-old hunter-gatherer. A genetic analysis reveals that this ancient strain was likely less contagious and not as deadly as its medieval version.

Scientists ने दुनिया में Plague से सबसे पहले मरने वाले शख्स का पता लगा लिया है और ये पता चला है उस शख्स की खोपड़ी से। वैज्ञानिकों ने Yersinia pestis का सबसे पहला Strain खोजने में कामयाबी पाई है।
