Scientists Say a Comet Did Not Wipe Out the Clovis Culture

ALBUQUERQUE, NEW MEXICO—An interdisciplinary team of 16 scientists has concluded that the disappearance of the Clovis culture could not have been caused by the collision of a meteor or a comet with the earth some 13,000 years ago. They cite the lack of an impact crater as a major blow to the case. “Despite more than four years of trying by many qualified researchers, no unambiguous evidence has been found [of such an event],” said physicist Mark Boslough of Sandia National Laboratories.
