GreenTracker| Researchers studying the origin of life — in a story different from the Biblical version — have focused on RNA, which is believed to have pre-dated living cells. Perhaps they have been tryng to hard to understand the mechanism by which RNA, a much more complicated molecule than a peptide, ‘blossomed’ into organisms from chemical stews.
Emory scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life. via Science Daily
