Brian Miller Talks Star-Crossed RNA Strands and the Origin of Life

On today’s ID the Future, physicist Brian Miller continues his conversation with host Eric Anderson. Here they explore more problems facing the idea that life began as strings of RNA. In their discussion of the RNA World Hypothesis and the origin of life generally, they touch on ideas advanced by Jeremy England, Jack Shostak, Nick Lane, Helen Hansma, and others. One of several big problems with the RNA-first hypothesis underscored by Miller and Anderson: For it to have even a slender chance of working, you need prebiotic Earth to generate not one but two information-rich RNA strands, and they somehow need to find each other before falling apart, and do so despite the fact that they aren’t looking for each other and the statistical odds of them bumping into each other at random are vanishingly small. What about approaching the origin of life from an intelligent design perspective? Miller explains why he’s convinced that the design perspective, far from stopping science, is actually much more fruitful than a blind-evolution approach.

New Origin-of-Life Proposal Revives a Hopeful Monster

On this episode of ID the Future, host Eric Anderson talks with scientist and fellow engineer Rob Stadler about a recent origin-of-life paper and how the authors paint themselves into a corner. The context for the paper is this: Decades of research have undermined the three great hopes for a purely naturalistic origin of life — scenarios starting with some sort of metabolism, scenarios starting with some kind of membrane, and scenarios starting with RNA. All three are necessary for cellular life; none seems able to have come ahead of the others. So now some recent work described in an article in New Scientist suggests it all happened at once in a sort of “chemical big bang.” It’s the return of an old idea long ago dismissed as too improbable. Is this “hopeful monster” plausible after all? As Anderson and Stadler show, there are numerous hidden assumptions and imaginary entities lurking in the proposal, which when surfaced, call its soundness into question.
