   That is an aspect of slushball Earth theory, the idea that there were small,   
   habitable zones near the equator, and that glaciers menace it, forcing life to   
   adapt.  The largest problem with the snowball Earth concept is that we exist.   
      
   Scientists will exaggerate the importance of their proposals to apply for   
   money with this sort of statement.  When I see something like this in print,   
   especially when somebody is put on TV and it's their day in the Sun, I'm very   
   careful about how    
   seriously I take it.   
      
   When these guys show you a rock on TV and tell you that this is absolute proof   
   that Earth was once a complete snowball, you should remember that eozoons in   
   Canadian limestone were supposed to have been fossil evidence of the deep   
   PreCambrian first life    
   on Earth for a hundred years, until 1970, when Mt. Vesuvius began to spit   
   eozoons into the sky.
