Scientists from the University of Edinburgh said that a connection could be established between the impact of a comet, which occurred 13 thousand years ago, and a change in the development of civilization. They will try to prove this in further research.
Researchers have discovered a possible connection between the fall of comet fragments to Earth 13 thousand years ago and a change in the development of civilization on the planet. Perhaps the most devastating cosmic impact since the extinction of the dinosaurs has coincided with major changes in the organization of human society, scientists say.
Their analysis confirms that the impact occurred before the Neolithic period in southwest Asia. During this time, people in a region that spans part of modern-day countries such as Egypt, Iraq, and Lebanon moved from a hunter-gatherer lifestyle to farming and establishing permanent settlements.
The team said a large body of evidence supports the theory that a comet impact occurred about 13,000 years ago. The researchers analyzed geological data from four continents, especially North America and Greenland, where the largest fragments are believed to have fallen.
Their analysis revealed elevated levels of platinum, indications of materials melted at extremely high temperatures, and the detection of nanodiamonds that exist inside comets and are formed during high-energy explosions. All of this data strongly supports the impact theory, the researchers say.
The team says further research is needed to figure out how this might have affected the global climate and associated changes in human populations or animal extinctions.
