I’ll bow out by asking everyone but especially @Eddie to think about this and to aim to understand it. It’s worse than @Mercer writes here, actually. Not only did this author miss or misrepresent the truth about this epic and central enzyme, but he did it while writing about the RNA World in an attempt to discredit it. To portray this as a little mistake in the midst of an otherwise sound treatise is to butcher truth and knowledge grotesquely.
The next step is to admit that the author is not credible and that writings by him and his collaborators are suspect. And the immediate step after that is to ask whether and how to learn from credible sources. Basic intellectual integrity.
