RNA World hypothesis

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 Read More ›

On this ID the Future, biophysicist Cornelius Hunter and host Eric Anderson discuss the RNA World hypothesis, an explanation for how the first self-reproducing organism might have arisen via mindless chemical processes. Hunter and Anderson have each written on the topic, and together they unpack some of the many and growing problems with this RNA-first explanation for the origin of life. They also spotlight some recent admissions in mainstream scientific publications that it’s time to move on from the cherished but embattled RNA World. The conversation pivots off of a recent essay by Hunter at Evolution News, “RNA World: Repeated Downfalls, Repeated Resurrections.” For more on the challenges of creating the first self-reproducing biological entity, see Eric Anderson’s Chapter 3 Read More ›
