    Well, this is one possible way that RNA-based chemical activity could have led to life, but there are many other possibilities, including an earlier generation of molecules that were able to replicate already folded RNA, presumably by reversing the hydrogen bonding which hold the folds together. A ribozyme would not necessarily have to copy itself, although it's intriguing that the authors were able to achieve that feat, under fairly specialized conditions--cold temperature and triplet bases rather than the single bases used by the DNA polymerases we see today.
