Research suggests Black Death Bacterium afflicted longer than Previously Thou

A research has found that the Black Death, one of the most devastating pandemics in human history, afflicted human race longer than previously thought. A research team analyzed DNA from Bronze Age human skeletons and found that the plague had first emerged as early as 3,000 BC.

Yersinia pestis is the bacterium responsible for the Black Death and a number of other plagues in human history. The historic analysis of the disease’s spread and symptoms is same as that of modern outbreaks of bubonic plague.

The earliest infection has come from a German burial linked to the six-century Plague of Justinian. But, there are some historians who think that Y. pestis caused earlier outbreaks like the Plague of Athens.

According to some studies, during the Bronze Age, weapon and transport technologies were very famous. At that time, these technologies spread across Eurasia. Earlier in 2015, two ancient-genome studies described an exodus of people from today’s Russia and Ukraine.

Morten Allentoft, a researcher at the Natural History Museum of Denmark in Copenhagen who is a member of a team that analyzed DNA of about 101 Bronze Age skeletons, said, “But we didn’t know what the cause of these quite sudden migrations was”.

The team also examined DNA data from the Bronze Age skeletons to search the of Y. pestissequences. It found that teeth of about 7 individuals were positive.
