MessageToEagle.com - Two years ago, scientists
challenged the controversial theory that the impact of an ancient comet devastated the Clovis
people, one of the earliest known cultures to inhabit North America.
"this episode occurred at or close to the time of major extinction of the North American megafauna, including mammoths and giant ground sloths;
and the disappearance of the prehistoric and widely distributed Clovis culture."
Now, this controversial hypothesis has been officially debunked.
It has also been found that samples presented in support of the impact hypothesis were contaminated with modern material
and that no physics model can support the theory.
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 Earth's climate and terminated the Clovis culture.
They argue that other explanations must be found for the apparent disappearance.
A prehistoric human culture known as Clovis, is the name archaeologists have given to the earliest well-established
human culture in the North America. The Clovis culture thrived and then, abruptly, the culture disappeared.
Scientists have long wondered what exactly caused the disappearance of this people.
No appropriately sized impact craters from that time period have been discovered, and no
shocked material or any other features of impact have been found in sediments.
"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," he concluded.
