"Nothing Works at Every Step": James Tour and Stephen Meyer on the Origin of Life

Every biology textbook tells the same story: long ago, simple chemicals in a primordial soup came together by chance and became the first living cell. Give it enough time, we are told, and life was inevitable.

In “James Tour & Stephen Meyer React to the Origin of Life Debate (Ep. 1)”, two of the most formidable voices in the field sit down to test that story against the chemistry. Dr James Tour of Rice University is a synthetic organic chemist whom Meyer introduces as “one of the most distinguished scientists in the world”, with more than 600 peer-reviewed publications and over 150 patents. Dr Stephen Meyer of the Discovery Institute, author of Signature in the Cell, earned his PhD at Cambridge on the history and philosophy of origin-of-life biology. Their verdict is blunt. In Tour’s words: “at every step nothing works.”

What Life Actually Requires

Tour begins with what any theory has to explain. All life is made of cells, and every cell needs four classes of molecules: amino acids for proteins, carbohydrates, lipids for the membrane, and nucleic acids (DNA and RNA). These must work together as a system with internal regulation (homeostasis). “It is not just throwing a bunch of molecules inside a lipid… it is a factory.”

Meyer makes the key point: even biological evolution cannot begin until there is “at least a functioning cell,” complete with “an information storage, transmission and processing system inside the cell.”

The Researchers’ Hands Are on Every Step

The heart of the conversation is what Tour and Meyer call “investigator interference.” According to Tour, origin-of-life researchers “have not been able to make any of the four classes of chemicals that are needed for life”, even with intensive, hands-on lab work. When a reaction produces a messy mixture, they identify a trace of the compound they want, then “buy that fresh material from a manufacturer that isolates that from cellular sources,” from something that was already alive, and carry on to the next step.

Tour says this happens with Steve Benner’s RNA work. Benner calls his approach “hands-off,” but, according to Tour, he bought the ribose, bought the nucleotides “pre-loaded to polymerize,” and what he produced “had both the 3′–5′ linkage and the 2′–5′”, meaning it was “hooked up the wrong way over and over again.” Tour points out that even Jack Szostak, another expert cited by critics, said Benner had “gone with the hype rather than with the science.”

Meyer sums it up: “the chemistry acting on its own does not want to move in a life-friendly direction,” so it takes “repeated interventions from intelligent chemists.” The experiments, he notes, end up demonstrating the very thing they were meant to rule out: the need for intelligent agency.

Time Is Not the Hero

For decades, chance and time were said to make life “inevitable.” Meyer recalls George Wald’s famous claim that time is “the hero of the plot.” Tour turns it on its head: organic molecules “decompose under the very conditions in which they form.” Ribose has a half-life of about five hours in the reaction that makes it. “Time is your enemy.”

Every Point the Video Raises

Here is every point raised in the conversation, credited to the speaker:

1. A distinguished witness. Tour is rated among the top 50 scientists in the world, with over 600 peer-reviewed publications and 150-plus patents. (Meyer, 0:38)
2. Critics got it wrong. Every slide in the critical video “Elucidating the Agenda of James Tour” was wrong, Tour says, prompting his 13-part series on abiogenesis. (Tour, 1:45–2:47)
3. Doing the reviewers’ job. Tour says he does “the work that reviewers should have done”: the papers themselves “screamed out” that this could not be how life formed. (Tour, 2:09)
4. Two theories. Chemical evolution (the first cell from non-living chemicals) and biological evolution are separate; Tour’s critique targets the first. (Meyer, 3:24)
5. Hear both sides. “Beware the sound of one hand clapping”: arguments must be tested against criticism. (Meyer, 5:33)
6. Origin and nature are linked. You cannot explain life’s origin without first defining what life is. (Meyer, citing Oparin, 6:53)
7. Four classes of molecules. Life needs amino acids, carbohydrates, lipids and nucleic acids, working together as a system with homeostasis, “a factory.” (Tour, 7:44–8:48)
8. Redefining life. Researchers who cannot reach the target are now trying to redefine life. (Tour, 8:53)
9. A working cell must come first. Biological evolution requires a functioning cell with an information-processing system. (Meyer, 9:24)
10. Investigator interference. Even with intensive hands-on work, no one has made any of the four classes of molecules needed for life. (Tour, 10:24)
11. No chiral lipids. No one has made the chiral lipids life needs, or controlled their stereocentres. (Tour, 10:39)
12. Buying from life. Researchers identify a trace product, then buy pure material isolated from living sources for the next step: “every step is the cheat.” (Tour, 11:13–12:59)
13. Never homochiral. Even with all their work, they have never made homochiral (single-handed) material. (Tour, 13:04)
14. No ribose, no RNA. Researchers buy their ribose; John Sutherland’s hands-on synthesis is not homochiral. “If you can’t make ribose… you’re done.” (Tour, 15:02–15:38)
15. Chiral-induced spin selectivity. Ron Naaman’s work at the Weizmann Institute shows electrons must travel through chiral environments, so life needed “the chirality at the start”; it could not have evolved into it. (Tour, 16:06–16:50)
16. Single-handed amino acids. Proteins need exclusively left-handed amino acids for an underlying physical reason. (Meyer and Tour, 16:55)
17. The target moves further away every year: for every step forward, “there are many steps back.” (Tour, 17:46–18:13)
18. No simpler cells. Biophysicists have calculated minimal complexity: the simplest cell is “awfully complex.” (Tour and Meyer, 18:19–18:38)
19. Insiders admit it. Meyer’s Cambridge supervisor in 1990: “everyone in the field knows that everybody else’s hypothesis doesn’t work.” (Meyer, 18:43)
20. Hands-on, not hands-off. Experiments claim to be hands-off but need “repeated interventions by intelligent agents.” (Meyer, 19:12)
21. Benner’s work. His “hands-off” chemistry yields billions of compounds; he then buys pure homochiral material from cellular sources. (Tour, 19:47–20:25)
22. The NMR scan. It shows a useless mixture in which ribose is merely identified, never used. (Tour, 20:42–21:30)
23. Researchers overhype. The hype starts with the researchers, not the press, and popularisers repeat it. (Tour, 21:43)
24. Benner’s RNA was not RNA. It used bought nucleotides with mixed 3′–5′ and 2′–5′ linkages and branching. (Tour, 22:32–22:59)
25. Szostak’s rebuke. Jack Szostak said Benner “has gone with the hype rather than with the science”; the critics’ own experts disagree with each other. (Tour, 24:29–25:06)
26. The chicken-and-egg problem. DNA needs proteins and proteins need DNA; the “RNA world” was proposed to escape this. (Meyer, 25:24–26:29)
27. Building RNA is very hard. Attaching bases to ribose and adding a triphosphate is “very difficult chemistry,” even hands-on. (Tour, 26:57–27:34)
28. More ways to go wrong than right. 2′–5′ linkages act like interfering RNA and shut translation down. (Tour, 27:58–28:30)
29. A key concession. Critics conceded that carbohydrate chains need enzymes, but enzymes presuppose genetic information. (Tour and Meyer, 28:35–29:23)
30. Enzymes defeat the RNA world: “if you have to invoke enzymes to make the RNA world plausible, you have defeated the whole approach.” (Meyer, 30:26)
31. Specificity is everywhere. The need for specificity runs through sugars, RNA and peptides alike. (Tour, 31:14–32:10)
32. No self-copying RNA. RNA has never been shown to copy itself; primed systems manage only about 10%, and even that needs prior information. (Tour and Meyer, 35:01–35:33)
33. One RNA molecule won’t last. A single RNA molecule would survive only a day or two by hydrolysis, and magnesium chloride destroys it faster. (Tour, 35:36–36:50)
34. “At every step nothing works.” (Tour, 36:57)
35. The experiments assume what they deny. Simulation experiments rely on Lyell’s “the present is the key to the past”, yet present-day chemists are actively intervening. (Meyer, 37:48–38:05)
36. Relay synthesis. Chemists fish out and purify the right product at each step; prebiotic claims skip this by buying the product. (Tour, 38:25–39:38)
37. Lee Cronin’s system is “the most user-input system,” piping in reagents at exact times, and yields “junk”; his oil-and-water “cells” are a Marangoni effect. (Tour, 39:41–40:41)
38. Not self-purifying. Cronin’s “self-purifying” system was purified by removing about 30% of the material each cycle: “you purified it.” (Tour, 41:20–42:07)
39. Billions of compounds. The formose reaction yields billions of compounds in seconds to hours. (Tour, citing Cronin, 42:19)
40. Information. DNA bases function “like alphabetic characters in a written language,” as Crick’s sequence hypothesis recognised. (Meyer, 44:24–44:46)
41. The interactome problem (Levinthal 2.0). The astronomically many possible non-covalent arrangements between molecules must be just right. (Tour and Meyer, 45:01–47:34)
42. The Humpty Dumpty problem. A dehydrated cell can never be brought back to life once its arrangement is lost. (Tour, 48:00–48:21)
43. The cell’s complexity keeps rising: “The cell is not getting more complex; our understanding of it is.” (Tour, 48:54)
44. “No idea.” Pressed, Cronin admits no one knows how small molecules became a cell: “there was no life and then there was life.” (Tour, 49:21–49:50)
45. “The emperor had no clothes.” Cambridge scientists privately admitted no one knows how life arose by undirected processes. (Meyer, 50:00–50:46)
46. Specificity at every level: the building blocks, their arrangement and their interactions. (Meyer, 50:48–51:13)
47. Time is the enemy. Ribose has a five-hour half-life in its own formation conditions. (Tour, 52:00–52:58)
48. The gap between hype and evidence. There is “a huge disparity” between what the press, textbooks and bloggers say and what the science shows. (Meyer, 54:19–54:34)

How This Supports Earlier Logos Posts

Challenges to Whale Evolution from Land Ancestors. That post showed how biological evolution struggles to explain a single major transition. This conversation goes one step earlier. As Meyer says, biological evolution cannot even begin without “at least a functioning cell.” If chemistry cannot produce the first cell, the evolutionary story has no starting point at all. The “insufficient time” problem in post 182 has a striking parallel here: Tour shows that time is not the hero but “your enemy.”

The Cosmic Witness: The Collapse of Secular Cosmology. That post showed that the heavens refuse to fit the secular model. This video shows the same pattern in the cell: the more we learn, the further the naturalistic target moves away. In both the cosmos and the cell, honest observation points to a created order. Experiments that need intelligent chemists at every step only confirm that life needs an intelligent Author.

“For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse.” (Romans 1:20)
