An ancient strain of plague may have led to the decline of Neolithic Europeans

A team of researchers from France, Sweden, and Denmark have identified a new strain of Yersinia pestis, the bacteria that causes plague, in DNA extracted from 5,000-year-old human remains. Their analyses, publishing December 6 in the journal Cell, suggest that this strain is the closest ever identified to the genetic origin of plague. Their work also suggests that plague may have been spread among Neolithic European settlements by traders, contributing to the settlements’ decline at the dawn of the Bronze Age.

Rethinking the history related to indigenous sites in northeast North America

After radiocarbon dating of plant matter, wood and wood charcoal, scientists estimate that the presumed histories of several key indigenous sites in Canada, as relates to first contact with Europeans, are incorrect by about 50 to 100 years. The findings suggest that European trade goods previously used to date individual locations are not in fact good chronological markers and that the history of notable “contact-era” events in northeastern North America during the 15th to early 17th centuries may need to be revaluated.
