The Origin so the Ribosome (and a model for the prebiotic synthesis of complex structure)

Today, an article was brought to my attention about the (likely) origin of the ribosome. Although may other sites around the Internet are carrying this story, there are essentially 3 versions with differing degrees of detail which I will list below:
1) Origins Of Complex Structure Explained By University Of Montreal Scientists
2) Ribosome Building Blocks (Astrobiology)
3) Deconstructing the Ribosome (Science)

To summarize, Dr. Sergey Steinberg of the University of Montreal discovered the stepwise mechanism responsible for ribosome assembly through the utilization of molecular modeling techniques. What is, perhaps, most impressive about the study is the notion that the precise, step-wise assembly of the ribosome was so reliant on each preceding step that in essence, it would have been impossible for components to form anything but a ribosome! The fact that this discovery was made in Canada is just the icing on the cake!
