Difference (from prior major revision) (no other diffs)

Changed: 13c13,16
I recall reading somewhere about a theory that the first life used PNA instead of RNA or DNA; that's "peptide nucleic acid", IIRC. The nucleotide bases were mounted on a backbone that was joined together with peptide (protein) bonds instead of sugar phosphates, which was much more stable than either DNA or RNA in open solution. Anyone know what I'm talking about, or am I remembering phantoms? -BD

Some things a lay person asks upon reading this: who has worked on, supported, first described the hypothesis, and when did they do so?
