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.

By now, you may have heard about some of the problems facing the field of origin-of-life research. Maybe you’ve come across Dr. James Tour making the argument that origin-of-life researchers are nowhere near their goal of creating life in a lab or proving a chemical evolutionary scenario for the origin of life. On today's ID The Future, we hear from another expert in origin-of-life chemistry and prebiotic synthesis: Dr. Edward Peltzer. Host Casey Luskin begins a conversation with Peltzer about the significant chemical hurdles facing origin-of-life research, specifically regarding the synthesis of biological building blocks. This is Part 1 of a two-part conversation. Look for Part 2 in a separate episode. Read More ›
Some people attempt to reconcile belief in God with the standard evolutionary account of life's origins by combining the two. Theistic evolution is the view that God used evolutionary mechanisms to create life. But does this view stand up to scrutiny? Today, Dr. Casey Luskin critiques this perspective in the first half of a conversation that originally aired on the Truthful Hope podcast.
The conversation kicks off with some clarity over terms, including what is meant by “evolution.” The theistic evolution perspective, also sometimes called evolutionary creation, accepts the standard scientific evolutionary account—the same view held by atheists—and simply adds the theological claim, "but this is how God did it". Critically, these proponents reject the idea that design can be empirically or scientifically detected in nature. As Luskin highlights, the central scientific problem with theistic evolution is that it inherits all the numerous scientific problems associated with the standard evolutionary account. This first half of the conversation rounds out with examples of those problems, specifically from the issue of the origin of life. This is Part 1 of a two-part conversation. Read More ›
In 1984, three scientists dared to probe the mystery of life's origin by putting the prevailing theories of prebiotic and chemical evolution to the test. One of those men was engineer Walter Bradley. Today, Dr. Robert J. Marks joins host Andrew McDiarmid to share some of his personal anecdotes and professional insights about Dr. Bradley, a scientist, humanitarian, and trailblazer in the world of intelligent design who passed away this summer at the age of 81. A Distinguished Fellow of the Discovery Institute, Bradley taught mechanical engineering at Texas A&M University, Baylor University, and the Colorado School of Mines. His book, co-authored with chemist Charles Thaxton and geochemist Roger Olsen, deeply influenced prominent figures in the intelligent design research community like Stephen Meyer, Douglas Axe, and Jay Richards and helped to catalyze a new generation of inquiry into life’s beginnings. The Mystery of Life's Origin was re-released in 2020 as a new, expanded second edition. Read More ›
By now, you might think that the icons of evolution that Dr. Jonathan Wells wrote about 24 years ago have been put out of our misery. And indeed, much has changed, and these icons have even less ground to stand on than they did back then. But they don’t call them icons for nothing! Whatever else they are, they’re stubborn, and it’s not uncommon to see evidence of them still popping up in popular science articles, cartoons, movies, and even scientific journals. On this episode of ID The Future, host Andrew McDiarmid welcomes back freelance science reporter David Coppedge to give us a few recent examples of the icons of evolution that keep shambling along, including recent sightings of the peppered moth myth and the Miller-Urey experiments.

What does it take to stay alive? On this ID the Future, host Eric Anderson concludes his conversation with physician Howard Glicksman about the remarkable systems in the human body that help control water and sodium to keep us alive. In Part 2, Dr. Glicksman discusses two more innovations that add a "push-pull" effect to the systems discussed in Part 1. First, a sensor in the heart kicks into action when water or sodium levels get too high. Second, an anti-diuretic system in the hypothalamus that detects cell shrinkage and promotes water retention. In true engineering fashion, these systems are interdependent and tightly integrated, working together in unison (along with your own active participation!) to safeguard your body and help you live your best life.

On their own, the laws of nature don't tend toward life. To stay alive, living things utilize ingenious solutions. On this ID the Future, host Eric Anderson talks with physician Howard Glicksman about another way that the human body counteracts the natural tendency of the laws of nature to destroy life.
Glicksman explains how the body controls water volume and sodium--two aspects that are absolutely critical to keeping us alive. It isn't just a single system. It's an interconnected and interdependent system of systems using a network of sensors, integrators, and effectors to maintain the life-giving balance of water and sodium in our bodies.

The RNA world is proposed by some to explain how early life began before DNA. But is RNA capable of maintaining a life-friendly self-replication rate? On this ID The Future, host Andrew McDiarmid welcomes back Dr. Jonathan McLatchie to discuss another headache for the RNA world scenario. Before a trial and error process like natural selection can even get started, self-replicating molecules must have a minimal accuracy rate to copy genetic material effectively. The required fidelity rate is estimated to be 2%. Any error rate higher than that results in error catastrophe for organisms. The average error rate in RNA copying is estimated to be around 17%, vastly higher than the estimated maximum error threshold for survival. McLatchie explains the implications of this for chemical evolutionary theories like the RNA world hypothesis. He also explains how a Bayesian approach to this evidence can provide us with the likeliest explanation for the origin of biological life. "The sorts of features that we observe in life are not particularly surprising if we suppose that a mind is involved," says McLatchie. But things like minimal self-replication fidelity are wildly surprising on a naturalistic hypothesis. Read More ›
When scientists claim they have simulated early earth chemistry to create life from non-life, are they being honest? This episode of ID The Future is the fourth and final installment in a series of conversations between philosopher of science Dr. Stephen Meyer, author of Signature in the Cell: DNA and the Evidence for Intelligent Design, and Dr. James Tour, a world-leading synthetic organic chemist at Rice University. Dr. Tour has recently been engaged in a series of back-and-forth responses to attacks on his work from YouTube science communicator Dave Farina. This has given Tour a new opportunity to critique experts in the field of abiogenesis and allows an interested public to better evaluate both sides of the argument.
In Part 4, Meyer and Tour evaluate the work of chemist Bruce Lipshutz; specifically his work designing surfactant molecules that enable amide/peptide bonds. By itself, Lipshutz’s work developing synthetic techniques for doing chemistry in water is interesting and has value. But for those tempted to think that his work validates chemical evolutionary theories of the origin of life, Tour has bad news. Peptides don’t form in aqueous environments like water. A realistic prebiotic environment would not be capable of producing the reactions necessary to form proteins. And Lipshutz acknowledges this. In their conversation, Tour and Meyer discuss how Lipshutz applies hands-on chemistry that bears no resemblance to the likely conditions of a prebiotic earth. If anything, the work of Lipshutz and others in origin of life research is actually simulating the need for intelligent agency to move simple chemicals in a life-friendly direction. Says Meyer, "Even the modest movement they get towards life seems to be intelligently designed at each step of the way, and even the vocabulary will sometimes reveal that: ribozyme engineer, designer surfactants. Very curious!"

When left to their own devices, the laws of nature tend toward death, not life. So what does it take for life to exist? On this ID The Future, host Eric Anderson talks with physician Howard Glicksman about some of the remarkable engineering challenges that have to be solved to produce and maintain living organisms such as ourselves. Glicksman is co-author with systems engineer Steve Laufmann of the recent book Your Designed Body, an exploration of the extraordinary system of systems that encompasses thousands of ingenious and interdependent engineering solutions to keep us alive and ticking. In the "just so" stories of the Darwinian narrative, these engineering solutions simply evolved. They emerged and got conserved. Voila! But in this chat, Anderson and Glicksman explain that it takes more than the laws of nature to keep us from dying. "Chemicals on their own don't have any desire or tendency to turn into living organisms," says Anderson. "They tend to degrade, they tend to break down, they tend to go back to their basic constituents." Glicksman and Anderson discuss examples, including how the human body handles friction, heat transfer, and the crucial task of maintaining chemical balance at the cellular level. And where does all this essential innovation come from? Glicksman points to an intelligent cause that transcends matter and energy. Read More ›
