But real lightning would have struck infrequently—and mostly in open ocean, where organic compounds would have quickly ...

a modified version of PHA synthase that could polymerize amino acid monomers. These enzymes enabled bacteria to create PEA precursors and link them into polymer chains. Initially, the process was ...
