Comet explosions did not end the prehistoric human culture, known as Clovis, in North America 13,000 years ago, according to esearchers from Royal Holloway university, who, 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.
"The theory has reached zombie status," said Professor Andrew Scott from the Department of Earth Sciences at Royal Holloway. "Whenever we are able to show flaws and think it is dead, it reappears with new, equally unsatisfactory, arguments. "Hopefully new versions of the theory will be more carefully examined before they are published."
