Submission + - Transition Metal Catalysts : Key to Origin of Life

An anonymous reader writes: One of the big, unsolved problems in explaining how life arose on Earth is a chicken-and-egg paradox: How could the basic biochemicals—such as amino acids and nucleotides—have arisen before the biological catalysts (proteins or ribozymes) existed to carry out their formation? In a paper appearing in the current issue of The Biological Bulletin, scientists propose that a third type of catalyst could have jumpstarted metabolism and life itself, deep in hydrothermal ocean vents.
