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!"

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.
