In 2022, the possible origin of all modern strains of Yersinia pestis was found in DNA in human remains in three graves located in Kyrgyzstan, dated to 1338 and 1339. The first recorded occurrence of the Black Death occurred shortly thereafter during the siege of Caffa in Crimea in 1346, and was carried to Europe by boat by people attempting to escape the disease. The strain was identified as the most recent common ancestor of both strains found in historic graves and currently existing strains.

Holy shit that’s wild
