The researchers compared the DNA sequences of 35 modern people living on islands off the coast of New Guinea with DNA drawn from two early human species: Denisovans, whose remains were found in Siberia, and Neanderthals, first discovered in Germany.
Black Death plagued humans since Bronze Age
It turns out the plague was plaguing humans far earlier than previously believed.New research using ancient DNA has revealed that plague has been endemic in human populations for more than twice as long as previously thought and that the ancestral plague would have been predominantly spread by human-to-human contact, until genetic mutations allowed Yersinia pestis (Y. pestis), the bacteria that causes plague, to survive in the gut of fleas.
