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.
