    Very interesting indeed. Funny wording in that the article spoke only of
Earth-life being spread elsewhere, and did not make the rather obvious
suggestion that incoming comets and other impact debris hitting Earth may
have *delivered* micro-organisms from earlier planetary systems, and indeed
may have been the source of life on Earth. Surely it's a two-way street?
