Consider the predicament faced by a team of scientists at Scripps Research. They suspected that RNA was a poor candidate for life chemistry’s original self-replicating molecule. RNA, they believed, was simply too sticky. That is, they thought that complementary RNA strands in the primordial ooze would have had a hard time separating because strand-separating enzymes would not have existed yet. And yet these same scientists had found that...
