Touted as his best episode yet, Dr. James Tour brings everything taught previously into Part 1 of this multipart episode, discussing the construction of the cell and the problems of its assembly. With the surgical lights now shining directly on the subject, Dr. Tour begins his vivisection, exposing the sophistry of the origin-of-life narrative held by many while systematically excising fallacy by fallacy where the storytelling should stop. With the state of the origin-of-life field remaining stagnant post-Miller-Urey, Dr. Tour short circuits with yet another reference—an honest scientist studying the homochirality problem who remains circumspect in conducting autocatalysis toward homochirality with prebiotic relevance. Finally, after the biopsies of dissected specimens like RNA World come back from the pathology lab showing no signs of viability, Dr. Tour lists requirements not addressed by the cited fairy tale, including an unraveling of covalent molecular synthesis that somehow is being hand-waved into existence via a magical, nonsensical force called “spontaneous assembly”.

Clarification at 35:58: It was stated “If it’s not homochiral, it’s not ribose”, meaning, if it’s not D-ribose, then it’s not of general prebiotic relevance, which is what was assumed from the discussion context.
