"The odds of being hit by a meteorite are much greater than anyone in America dying of mad cow disease." Interestingly, there is some science behind the speculation that something like a prion protovirus may have been carried to the early Earth by a meteorite, since life on Earth seems to have developed within 400 Mya after cooling. But no one can be sure yet, since there are also models for a rapid RNA world that might work. Certainly the prion that causes mad cow was not brought by a meteorite though, since it is too host-specific. Unless there are cows in space. Now that would make interesting meteorites. :) Francis Graham __________________________________ Do you Yahoo!? Find out what made the Top Yahoo!
