A new study advise the
hypothesis of Clovis comet - a giant celestial body collision with the Earth,
which occurred nearly 13,000 years ago, which is completely erased from the
face of the planet ancient North American Clovis culture.
An international team
of scientists from seven institutions of the United States argues that the
neglect of three key protocols, including sorting the samples by size, explains
why the team, the disputed theory that Clovis comet, did not find the iron-rich
and silica-magnetized particles in the places that she explored.
In a new independent
analysis were isolated large quantities of so-called "microspherules"
in the same places where the past research found nothing. Lead author of the
new Malcolm Le Compte (Malcolm A. LeCompte), an astrophysicist at the State
University Elizabeth City, North Carolina, said that these findings support the
theory of cosmic collision that led to climate change, but his team is not
enough data to officially announce on the proof of the event.
The study was published
online last week in the Early Edition of the Proceedings of the National
Academy of Sciences.
