 It seem very improbable.  Although I misunderstood the post a bit, there is 
a valid claim that the life could of originated on earth.  If conditions were 
more favorable on Mars in the past, and rock from the earth could of seeded 
Mars (where evolution would take a different course) to bring it back in the 
future to Earth.  The scenario would work just as well for life originating 
on Mars.
