Europe’s Plagues Came From China, Study Finds By NICHOLAS WADE The great waves of plague that twice devastated Europe and changed the course  of history had their origins in  China , a team of medical geneticists reported  Sunday, as did a third plague outbreak that struck less harmfully in the 19th  century. And in separate research, a team of biologists reported conclusively this month  that the causative agent of the most deadly plague, the Black Death, was the  bacterium known as Yersinia pestis. This agent had always been the favored  cause, but a vigorous minority of biologists and historians have argued the Black  Death differed from modern cases of plague studied in India, and therefore must  have had a different cause. The Black Death began in Europe in 1347 and carried off an estimated 30 percent  or more of the population of Europe. For centuries the epidemic continued to  strike every 10 years or so, its last major outbreak being the Great  Plague  of  London from 1665 to 1666. The disease is spread by rats and transmitted to  people by  fleas  or, in some cases, directly by breathing. One team of biologists, led by Barbara Bramanti of the Institut Pasteur in Paris  and Stephanie Haensch of Johannes Gutenberg University in Germany, analyzed  ancient DNA and proteins from plague pits, the mass burial grounds across
