potentially devastating comet Has the impact of Earth’s distant past changed human civilization forever?
Scientists think a group of comet fragments may have crashed into world surface 13,000 years ago, in the worst impact since the Chicxulub event killed the Earth’s massive dinosaurs about 66 million years ago, in a new study, a team led by Martin Sweatman, a scientist at the University of Edinburgh in Scotland. It examined the impact and how it could shape the origins of human society on Earth.
while the first time Homo Sapiens It happened 200,000 to 300,000 years ago, which is far more than this effect. The researchers found that this comet̵

Researchers examined the theory that comets hit Earth 13,000 years ago, analyzing geologic data from areas where they think they may have hit Earth, including North America and Greenland. They found high levels of platinum. This is evidence of the extremely high temperatures that can melt the material at the site and the nanodiamonds. which scientists know can be generated by explosions and can reside inside comets.
This work builds on previous research suggesting that significant effects may precede the beginning of new stone ageThis was the first part of the Stone Age, which had several important developments in human civilization. This includes remarkable advances in agriculture, architecture and stone tools.
At this time in history, the humans in the “Fertile Crescent” that encompassed the nations As we know today, such as Egypt, Iraq and Lebanon, have moved away from the nomadic lifestyle. hunter-gather towards more permanent settlements.
“This cosmic cataclysm appears to be a relic of Kobe Klitpepe’s giant monolith. [in Turkey]It may be the ‘world’s first temple’, linked to the origins of civilization in the rich crescent of southwest Asia. So civilization started with a bang?” Sweatman. said in a statement.
While the new research is exciting and suggestive, The team acknowledges that more evidence and research is needed to better understand how this effect might ultimately affect the global climate and human civilization.
This work is described in the study. Published May 19 in the journal Earth-Science Reviews.
