About 5000 years ago, a 20-year-old woman was buried in a mausoleum in Sweden, one of Europe’s oldest farmers. Now, the researchers discovered what killed him – Yersinia pestis, plague-secreting bacteria. The example is one of the oldest found, and Y. pestis belongs to a previously unknown branch of the evolutionary tree. He said the newly discovered plague epidemic could be the first pandemic researchers in the world, which could lead to the collapse of the major Stone Age settlements in Europe. However, other scientists claim that there is not enough evidence to prove the case.
Plague is beginning to appear everywhere, as Kyle Harper examines how Har Norman’s historian influenced human societies at the University of Oklahoma. Ba We have a really long history with this germ, bir says the new plague genomes of plague diseases.
The oldest known plague epidemic has come to Europe with the shepherds Yamnaya from the central Eurasian steppe, which was drifted into the continent about 4800 years ago. The following several thousand years later, he followed up with Justinian Veba, who had influenced the Roman Empire in the sixth century and the tension that led to Black Death, which killed half of Europe’s population in the 1300s.
The discovery of the new strain was coincidental. A team led by Simon Rasmussen, a calculation biologist at the University of Copenhagen, and Nicolás Rascovan, a biologist at the University of Aix-Marseille in France, scanned old publicly available DNA data sets for genetic sequences of common human pathogens. A 20-year-old woman reported on Y. pestis arrays in Cell in the teeth of another person buried in the grave of Frälsegården west of Sweden and buried in the same grave. Both were farmers from the Huni Beaker culture in Scandinavia and either had no trace of the Yamnaya ancestors. This meant that there was a species of plague in Europe before the arrival of steppe migrants. Rasmussen says that his bacteria are hiding in his teeth, and he probably kills them.
The newly discovered Neolithic bacterium belongs to an arm of the plague family tree separately from the later known strains. Rasmussen and Rascovan say they left a common ancestor 5700 years ago. However, Johannes Krause, a geneticist at the Max Planck Institute for Humanity in Jena, Germany, and Johannes Krause, a writer investigating the old plague epidemic, do not explain where and when they emerged, not the common proverb itself. Ba I’m not sure we have a good idea of how far [plague] is going,] says Anne Stone, an anthropological geneticist investigating ancient pathogens at Arizona State University in Tempe.
Rasmussen and Rascovan have an idea. In the Neolithic period, the region, which now includes the regions of Moldova, Romania and Ukraine in Eastern Europe, was hosting the geler mega-yeast ke of tens of thousands of people whom archaeologists called the Trypillia culture. Although the settlements were not so complex as the city, their inhabitants still lived in poor areas with poor hygiene and grain stores that attracted the rodents who were Hitler’s wild hosts. Id These megasettives are the textbook example of a place where a pathogen can evolve, Ras says Rasmussen.
But about 5400 years ago, most mega-yeasts collapsed. The residents died or moved and the abandoned buildings were burned. Rasmussen and Rascovan argue that new plague epidemics may be guilty. Şey Perhaps this is the first thing that a great society has been the first to be plagued, Ras says Rasmussen. And because these megasettifications were connected to other communities through trade routes across Europe, bacteria could easily spread to places such as Sweden. Olabilir This could be the first pandemic in principle, Ras says Rasmussen.
Nevertheless, the only way to know for certain is to find evidence of Y. pestis in the collapsed empires itself. Without it, ra is highly speculative, “Krause says. And this early strain does not have genetic adaptations, which are then lethal and affect the lungs and facilitate their capture, such as their ability to spread through fleas, from rodents to humans. “A. Does this particular branch of pestis have what it takes to cause an outbreak? Without knowing more about this tension, how a 20-year-old woman can catch up on her illness and become a victim of a wider pandemic remains a mystery.
