Summary

On today's ID the Future, host Casey Luskin continues a deep dive into the mounting hurdles facing origin of life (OOL) research with prebiotic synthesis expert Dr. Edward Peltzer. Peltzer, a seasoned ocean chemist and researcher, breaks down the critical flaws in the RNA world hypothesis, revealing that many successful lab experiments actually rely on investigator interference—intelligently designed interventions that researchers must make in experiments in order to yield results. But that's not how the prebiotic atmosphere would have worked, notes Peltzer: "Unless you've got graduate students and post-docs working on the early Earth to set up these conditions that were used in the experiments, it's not gonna happen." Peltzer also discusses how the goalposts of origin-of-life theory keep moving as our understanding of cellular complexity expands. And he shares a personal story of censorship as the discussion ends by exploring the risks faced by scientists who question the standard evolutionary paradigm. This is Part 2 of a two-part conversation. Look for Part 1 in a separate episode.

0:00.0	The papers that I'm familiar with, there's always been some kind of investigator interference.
0:08.7	They put leaving groups on to help the RNA couple together, and they block other sites.
0:17.2	So it makes the right phosphate bond backbone.
0:22.7	And so unless you've got graduate students and postdocs working on the early earth
0:27.8	to set up these conditions that were used in the experiments, it's not going to happen.
0:36.9	ID, The Future, a podcast about evolution and intelligent design.
0:43.6	By now, you've likely heard about some of the problems facing Origin of Life studies today.
0:49.5	Maybe you've heard Dr. James Tuer making the argument that Origin of Life researchers are nowhere near their
0:55.5	goal of creating life in a lab or proving a chemical evolutionary scenario for the origin of life.
1:01.9	Welcome to Idea the Future. I'm your host, Andrew McDermid. Well, today we're going to hear more
1:06.8	from another expert in prebiotic synthesis and origin of life chemistry.
1:11.9	His name is Ed Peltzer.
1:14.0	In this second half of a conversation with Dr. Casey Luskin,
1:17.5	Peltzer discusses some of the problems associated with the RNA world hypothesis,
1:22.7	the idea that life may have first emerged through simpler RNA molecules.
1:29.6	Peltzer also discusses the debate over the conditions of the early Earth atmosphere and shares his expert opinion on what he thinks
1:35.0	that could have been. And if you stick around to the end, he also shares his own censorship story,
1:40.3	an all too familiar hazard of the job for scientists who dare to question the standard
1:45.9	evolutionary paradigm. Now, let's get back to the conversation with Ed Peltzer and Casey Luskin.
1:53.2	So let's switch over to RNA a little bit if you don't mind. I don't know if you've looked at
1:59.6	the production of RNA.
2:01.1	There have been some experiments where they've claimed to be able to produce some of the nucleotides.
