According to a new study, scientists have identified the origin of the Black Death plague.

The Black Death was a plague epidemic that killed 25 million people in Europe and tens of millions more worldwide.

Historians have debated where it came from. According to a new study in the science journal Nature, the Black Death started in central Asia in the late 1330's.

The teeth of seven skeletons were analyzed by a team of researchers from Scotland, Germany, and the University of Tubingen.

The study said that three people carried a bacterium that was linked to the plague.

The Black Death was thought to have started in the Black Sea region in the 13th century.

The spike in burials between 1337 and 1339 was identified by the scientists and they chose the cemeteries near Lake Issyk Kul.

The causes of death were listed as "pestilence" in some of the headstones.

The victims of the Black Death would have died in pain. The most common symptoms of the bubonic plague were large blisters in the body. There was a rapid rise in blood pressure and a rapid rise in temperature. The skin becomes black. They would have died within a couple of days after being bitten.

The presence of Yersinia pestis in the exhumed bodies points to an earlier origin date for the plague than was previously thought.

"Our study puts to rest one of the biggest and most fascinating questions in history and determines when and where the most notorious and notorious killer of humans began," said Philip Slavin, a University of Stirling historian.
