ribozyme

On today’s ID the Future, scientist and Stairway to Life co-author Rob Stadler and host Eric Anderson examine a recent PNAS paper on origin of life, “An RNA Polymerase Ribozyme that Synthesizes Its Own Ancestor.” A superficial look at the paper—and the paper’s title in particular—might give the impression that the laboratory findings behind the paper render the blind evolution of the first self-replicating biological system appreciably more plausible. Not so fast, says Stadler. Listen in as he and Anderson highlight various ways the laboratory work in question is wildly unrealistic.

On this ID the Future, Brian Miller, research coordinator for the Center for Science & Culture, reports on laboratory research recently presented in Nature Communications and in a University of Tokyo press release— research that supposedly provides dramatic “new insights into the possible origin of life,” and specifically “the molecular evolution of RNA.” The popular press picked up on these claims and ran with them, including in this May 5 Quanta article that breathlessly reported, “When researchers gave a genetic molecule the ability to replicate, it evolved over time into a complex network of ‘hosts’ and ‘parasites’ that both competed and cooperated to survive.” Miller says nothing remotely this dramatic occurred in the experiment. He insists there were no great Read More ›
