Recent reports published by a group of scientists and researchers found that the great Black Plague has been killing human kind around 5000 years ago. Apparently scientist has found evidence with the discovery of skulls in Asia and Europe, that the disease may have occurred earlier than theorized.
The Plague causing Bacteria Yersinia Pestis has been positively found in the sample skulls discovered in Europe, which is dated 4800 years old, the era of the Bronze Age. However, there is no concrete written history about the skulls.
It has been found that the skulls have traces of the origin of the disease back in the days, which filled the missing data's that scientist have been trying to find all this year about the disease. With the data gathered scientist can now divulge the information on how the bacteria evolved into a much more serious and deadlier disease that causes a massive pandemic that shattered the world in the 14th century.
The number of samples of the bones found were 101, all dated back to the Bronze Age. However, the bacteria found in the skulls were not as deadly as the bacteria in the Black plague, but scientist are positive that the discovery is a closer step towards understanding the greater disease.
Apparently the research also concluded that the original pathogen evolved into something more deadly, which caused for the 50 percent population decrease in Europe in the 14th century. Simon Rasmussen, one of the researchers stated that the discovery has been just a product of the research for the Bronze Age migrants from Russia that replaced the Europe's Stone Age population. Although it can be theorized that the migrants was killed by locals, it can also be plausible to think that an epidemic wipe out their population which they also brought into Europe.
For further studies, scientists are planning on expanding their research in many locations with a great history of having a blood eating bacteria. And in the process collect evidence on how actually the bacteria evolved, and understand more of its characteristics.
