   Henry,   
      
   My concern here is what happens when you dump RNA and DNA into a   
   reducing soup containing amino acids at whatever temperature.   
   Sometimes, or so I understand, the RNA and DNA replicate even without   
   an enclosing cell.  This could actually make a global change to the   
   chemistry of Titan, if it could occur under those conditions.  Proteins   
   can sometimes self-replicate, too.  This could cause a sort of   
   molecular evolution to begin there.  Not life-as-we-know-it, certainly,   
   but it would be very interesting should it happen...
