A team of scientists may have discovered the oldest human plague from the 5,000-year-old remains of a young woman in Sweden. It is possible that this plague may have wiped out the Neolithic farmers of Europe, a discovery that could change our understanding of European history.
The study suggests that a plague was spread by traders among Neolithic European settlements and wiped them out, allowing for the massive human migration from Russia and Ukraine in Europe that came afterward, overturning the European gene pool. It has previously been debated how these migrants were able to displace the Neolithic farming culture.
