It's actually a pretty decent little article on where we are now with various hypotheses on the prebiotic origins of RNA. The summation is here:

"Whether RNA arose spontaneously or replaced some earlier genetic system, its development was probably the watershed event in the development of life. It very likely led to the synthesis of proteins, the formation of DNA and the emergence of a cell that became life's last common ancestor. The precise events giving rise to the RNA world remain unclear. As we have seen, investigators have proposed many hypotheses, but evidence in favor of each of them is fragmentary at best. The full details of how the RNA world, and life, emerged may not be revealed in the near future. Nevertheless, as chemists, biochemists and molecular biologists cooperate on ever more ingenious experiments, they are sure to fill in many missing parts of the puzzle. "

luckily this guy is NOT saying "Since we don't know there must be creationism or ID at work". He's saying there are many interesting guesses out there, and scientists are looking for proof for them. I hadn't known about the theory of a simpler assembler than RNA- some earlier precursor genetic system that then because (oerhaps) the template for RNA.
