Key To Origin Of Life Could Be Transition Metal Catalysts
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...
