Comet explosions did not end the prehistoric human culture, known as Clovis, in North America 13,000 years ago, according to research published in the journal Geophysical Monograph Series.
Researchers from Royal Holloway university, together with Sandia National Laboratories and 13 other universities across the United States and Europe, have found evidence which rebuts the belief that a large impact or airburst caused a significant and abrupt change to the Earth’s climate and terminated the Clovis culture. They argue that other explanations must be found for the apparent disappearance.
