Closing in on the Dawn…before Darwin?

In a paper released this month in the Proceedings of the National Academy of Sciences, Mansy and Szostak showed that the special membranes, fat bubbles essentially, were stable under a variety of temperatures and could have manipulated molecules like DNA through simple thermal cycling, just like scientists do in PCR machines.

The entire line of research, though, begs the question: where would DNA, or any other material carrying instructions for replication, have come from?
