Concluding the discussion on Lee Cronin, this episode peers into the manufactured oil bubbles from his lab, looking for any resemblance of life's necessary machinery, either in modern cellular life or some prehistoric, protocellular precursor. With characterization data clearly showing a human-engineered and chemically loaded system steered for autocatalysis to yield oil bubbles (and failing to comprise a cellular lipid bilayer), Dr. Tour questions how Cronin's lab and his experiments truly operate autonomously and how the formation of the bubbles has anything to do with biological life. Rolling back the clock, we then watch Cronin present the idea of creating "evolvable matter" in the lab, once the "right chemistry" has been "set up"—rather, "input"—by the chemists. With inorganic rust not holding water, and other reactions yielding billions of unusable stereo-scrambled compounds, Cronin's lab hasn't met their projected deadline, yet the religion of prebiotic soup extrapolations continues to be preached. Dr. Tour concludes this episode with a list of outstanding abiogenesis problems in need of a solution.
