Why Hands-On Chemistry Experiments Can’t Simulate A Prebiotic Earth

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!" Watch the series on video at Dr. Meyer's YouTube channel: @DrStephenMeyer Read More ›

Smoke & Mirrors: Tour and Meyer Assess Origin of Life Experiments

Have scientists made life in a laboratory? Two-thirds of the public think the answer is yes. What do you think? This episode of ID The Future is the third installment in a series of four 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 3, Meyer and Tour continue their critique of the claims of chemist Lee Cronin, including his experiments on the formose reaction, autocatalysis, his attempts to conjure up lipids in oil, and more. Along the way, Tour explains how he got into the debate in the first place, providing some background on his interactions with Farina and how it led him to call out experts in the field. Tour and Meyer are careful to remind us just what life is and what it takes to build it. And on several occasions, you’ll enjoy Meyer’s insight into the big picture. These simulation experiments, says Meyer “are actually showing the difficulty of making life-relevant molecules…via an undirected process.” In other words, origin of life researchers are doing sophisticated chemistry with multi-million dollar equipment that can only be done in a modern lab! In the process, they’re showing us just how implausible chemical evolutionary theories actually are. This is Part 3 of a 4-part series.

Extravagant Claims: James Tour & Stephen Meyer Critique Origin of Life Research

On this ID The Future, we continue a four-part conversation series 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 2, Meyer and Tour discuss the work and claims of origin of life researcher Lee Cronin. They begin with a review of the four classes of molecules before critiquing Cronin’s foremose reaction experiments and his claims to have found a process that’s analogous to cell division. Tour also discusses the importance of chirality, as well as how amino acids behave in aqueous solutions. Turns out that “warm little pond” story we’ve been told for many years is chemically implausible. The discussion rounds out with a reminder of the information problem, something Meyer writes about at length in Signature in the Cell. Have prebiotic chemists made any progress on the sequence specificity problem? None whatsoever, says Dr. Tour. This is Part 2 of a four-part series of conversations.

James Tour and Stephen Meyer Bring Clarity to Origin of Life Debate

On this ID The Future, we kick off a series of conversations between Dr. Stephen Meyer and Dr. James Tour on the many challenges faced by origin of life researchers. Dr. Tour, a world-leading synthetic organic chemist at Rice University, 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 evaluate both sides of the argument. Philosopher of science Dr. Stephen Meyer hosts these engaging conversations. Meyer is author of the 2009 book Signature in the Cell: DNA and the Evidence for Intelligent Design, which explores theories attempting to explain the origin of the first life. So Meyer is the perfect candidate to unpack Tour's expertise and draw out key insights. In Part 1, Meyer and Tour critique the work of origin of life researcher Steve Benner. Along the way, they discuss the basic definition of life, the RNA world hypothesis, the problem with hands-on chemistry, and why the challenges facing origin of life research increase every year as our understanding of the cell grows. "What is being simulated is the need for intelligent agency to move simple chemicals in a life-friendly direction," says Meyer, and researchers "seem utterly blind to the role of their own hand, their own mind, in achieving the results that they get, such as they are." This is Part 1 of a four-part series of conversations.

James Tour Talks Origin-of-Life Dealbreakers

On today’s ID the Future, distinguished synthetic organic chemist James Tour of Rice University explains why the goal of synthesizing life from non-life in conditions similar to those of the early Earth appears further away than ever. It’s not an illusion, he explains. The illusion was how close OOL researchers thought they were 50-70 years ago. They were never close, and the more we learn about how mind-bogglingly sophisticated even the simplest cells are, and how the complexity is essential for biological life, the more we realize just how far we are from constructing a plausible scenario for the mindless origin of the first life. Tour points out that even granting a great deal of intelligent design in the form of the highly skilled and interventionist work of the origin-of-life researchers in the lab, they still can’t engineer into existence all the key building blocks of a living cell. What if you handed them all the building blocks in the right proportions? They’re still nowhere near being able to intelligently design those ingredients into a living cell, Tour says. It has to do with what’s termed the interactome—that is, all the interdependent molecular interactions in a particular cell, many of which may initially appear unimportant but turn out to be crucial. Tour doesn’t argue that researchers will never be able to design a cell from non-living matter. He does say that if it is achieved, it will be well into the future. What will such an achievement underscore? As Luskin emphasizes, it will highlight the creative power of intelligent agency. The occasion for Dr. Tour’s conversation with host Casey Luskin is Tour’s essay in a new book now available for free download, Science and Faith in Dialogue.

James Tour: The Goalposts are Racing Away from the Origin-of-Life Community

On today’s ID the Future distinguished nanoscientist James Tour explains to host Eric Metaxas why the origin-of-life community is further than ever from solving the mystery of life’s origin, and how the public has gotten the false impression that scientists can synthesize life in the lab. Tour explains that origin-of-life scientists aren’t even close to intelligently synthesizing life from non-life in the lab. The problem, Tour says, is that some leading origin-of-life researchers give the impression they are right on the cusp of solving the problem. Not so, Tour says. He offers the analogy of someone claiming, in the year 1500, that he has the know-how to build a ship to travel to the moon, when no one yet knows even how to build an airplane, car, or car engine. Tour says that if he took a cell that had just died a moment before and asked top origin-of-life researchers to engineer it back to life, they couldn’t do it. They’re not even close to being able to do it. And yet all the ingredients, all the building blocks of life are right there, all in one place, in the right proportions. And not only can scientists not engineer those ingredients back to life, they still can’t synthesize even a fraction of the building blocks essential to cellular life, despite decades and millions of dollars poured into the problem. And yet they assume that purely blind material processes turned prebiotic chemicals into all the key building blocks, and then mindlessly engineered those into the first self-reproducing cell on the early Earth. There are no models that would make such a scenario plausible. And the more we learn about cellular complexity, the harder the problem gets. Indeed, as Tour puts it, origin-of-life research is like moving down a football field in nanometer increments while the goalposts are racing away. What’s left is only the dogmatic assumption among origin-of-life researchers that the first life must have appeared on Earth purely through blind material forces. Tour has made it his mission to show the broader scientific community and the public that the emperor has no clothes. Not surprisingly, the origin-of-life community has not responded with heartfelt gratitude. Tune in to hear more of Tour’s argument and to learn what kind of blowback he has experienced.

James Tour: Primordial Soup Bluffing Goes Right to the Top

Today’s ID the Future features another installment in James Tour’s hard-hitting and evidence-based YouTube series on abiogenesis. Here Dr. Tour, a world-leading synthetic organic chemist at Rice University, describes the early Earth primordial soup concept for the origin of first life (OOL) and shows why it’s simplistic, bogus, and doesn’t represent the current science on the issue. He also reviews survey data showing just how misinformed the public is about how far scientists have gotten in creating life in the lab. One critic of Tour protested that the simplistic primordial soup story might be found in highly simplified textbooks for sixth graders but isn’t peddled at higher levels. Tour provides video evidence to the contrary.

James Tour–A Flyover of the Challenges Facing Abiogenesis

Today’s ID the Future features the next in a YouTube video series by Dr. James Tour on the origin-of-life problem. Here Tour, a distinguished synthetic organic chemist, lists the characteristics of life and describes some features of the early Earth where life first appeared. Then he provides a fast flyover of the many grave problems of blindly evolving the first living cell from prebiotic materials. 

A James Tour Course on Abiogenesis: Prologue

Today’s ID the Future features audio of the first in a series of YouTube videos by Dr. James Tour on the origin-of-life problem. Here Tour, a renowned synthetic organic chemist and professor at Rice University, explains why he is addressing the origin-of-life issue, also known as abiogenesis, and touches on some common misconceptions about the field. He says the organizing impetus for the series is a YouTube video by Dave Farina, “Elucidating the Agenda of James Tour: A Defense of Abiogenesis.” As Farina’s title suggests, he begins his video with an ad hominem attack, seeking to discredit Tour by showing that Tour is a Christian. Tour briefly responds to this line of attack and then moves into matters scientific. There he touches on, among other issues, thermodynamics and the origin-of-life puzzle of low entropy and high energy.
