Brian Miller on Life, Thermodynamics and Jeremy England

In today’s ID the Future physicist Brian Miller discusses fellow physicist Jeremy England’s book Every Life Is on Fire: How Thermodynamics Explains the Origin of Living Things. Has England made a significant step toward solving the mystery of how life first began? In Miller’s conversation with host Eric Anderson, he argues that while England’s laboratory work is fascinating and innovative, what’s happening in his experiments differs dramatically from what is required of even the simplest life, so much so that the experiments do not shed the kind of light on the mystery of life’s origin that some may hope they do. Moreover, life does certain crucial things with energy that are unknown outside of the biological realm, Miller says, and without those processes available to prebiotic chemicals, it is far from clear how they could ever assemble into the molecular biological machinery essential for the first self-reproducing biological entity.

A Mousetrap for Darwin, and Another for Richard Lenski

Today’s ID the Future extends the discussion of A Mousetrap for Darwin: Michael Behe Answers His Critics, the newest book from Discovery Institute Press. Here the focus is on Parts 4 and 7 of the new book, and in particular Richard Lenski’s Long Term Evolution Experiment at Michigan State. What has this long-running project demonstrated? As Behe explains in the book (and elaborates on in today’s podcast), “The study has addressed some narrow points of peculiar interest to evolutionary population geneticists, but for proponents of intelligent design the bottom line is that the great majority of even beneficial mutations have turned out to be due to the breaking, degrading, or minor tweaking of pre-existing genes or regulatory regions. There have been no mutations or series of mutations identified that appear to be on their way to constructing elegant new molecular machinery of the kind that fills every cell.” Listen in as Behe fills in the details with host Eric Anderson. And to dive still deeper, pick up A Mousetrap for Darwin here.

James Tour and Brian Miller Talk Engines We Can’t Live Without

Today’s ID the Future features Part 1 of an extended interview that first appeared on a podcast show hosted by distinguished Rice University synthetic organic chemist James M. Tour. As he typically does, since it’s the Science & Faith podcast, Dr. Tour begins his show by asking his guest for a statement of faith. Miller, a Christian, gives his, and then they dive into origin-of-life science. In a surprisingly accessible discussion given the depth of the material, the pair cover a range of issues—thermodynamics and the origin of the first cell, entropy, free energy, order and disorder, molecular engines, non-equilibrium thermodynamics, and the need for engines and information to overcome the vicissitudes of entropy. Also in the mix—feedback loops, Jeremy England, and much more.

Michael Behe on the Battle of the Mousetraps

_{Michael Behe

December 9, 2020

On this ID the Future, Michael Behe responds to the attacks on … his mousetrap. Behe used the common mousetrap to illustrate the idea of irreducible complexity, showing how various mechanical contrivances need all of their main parts to function, and to show how irreducible complexity poses a major challenge to Darwinism’s idea of gradual, step-by-step evolution of some biological machines. Most of the attacks on Behe’s argument have focused on the irreducibly complex biological systems he spotlighted, such as the outboard motor known as the bacterial flagellum. But some of his critics fixated on the mousetrap itself, and argued that the mousetrap wasn’t actually irreducibly complex. Behe rebuts these counterarguments and explains why he’s convinced they fail. The discussion is just a brief sampling of the deeper dive Behe takes in his newest book, A Mousetrap for Darwin.

Michael Behe on the Growth of ID via the Growth of Science

On this ID the Future, Michael Behe continues discussing A Mousetrap for Darwin, his newest book. Understanding of the cell has grown “by leaps and bounds” since the 1990s, when Behe’s first book appeared. Fresh discoveries have revealed ever more complex structures inside the cell. As Behe explains, it isn’t just the bacterial flagellum that’s irreducibly complex; the “hook” region inside the flagellum is, too. Evolution’s proper place of study has moved from gross anatomy and population genetics to biochemistry. In his conversation with host Eric Anderson, Behe says that intelligent design theory’s predictions are coming true over time, while for every step of increasing knowledge, it gets “worse and worse” for the theory of evolution by undirected unintelligent processes.

Evolution and Intelligent Design in a Nutshell — An Excerpt

_{Eric H. Anderson

May 27, 2020

Uncategorized}

On this episode of ID the Future, Eric H. Anderson reads from his newly co-authored book Evolution and Intelligent Design in a Nutshell, written to provide a clear and simple introduction to the evolution/ID controversy, and broad overview of the evidence for design in nature — including fine tuning and the Big Bang, the origin of life, irreducibly complex machines, and the Cambrian Explosion. In this chapter excerpt, Anderson tells of Richard Dawkins’ glib assurances that the mystery of the origin of life is one not far from being solved. Not so, Anderson says. Origin-of-life researchers haven’t found a pathway to a self-replicating biological entity, the beginning point for any sort of Darwinian evolution. And it’s not for lack of time, effort, or funding. The single cell that Darwin saw as a relatively simple blob has proven to be far more complex than anything imagined. What about a self-reproducing molecule, thought to be easier to evolve than a full-blown cell? As Anderson explains in Chapter 3 of the book, the idea remains a purple unicorn, and for reasons that are perhaps most easily appreciated by looking at the ongoing attempts to build a self-reproducing 3D printer.

Protein Scientist Douglas Axe at the Dallas Area Science and Faith Conference

On this episode of ID the Future, guest host Jonathan Witt sits down with molecular biologist Douglas Axe at the recent Dallas Science and Faith Conference. Axe, author of Undeniable: How Biology Confirms Our Intuition That Life Is Designed, had his research on protein folds published in the Journal of Molecular Biology, work showing that random mutations are not up to the task of building fundamentally new protein folds from old, a finding that poses a major challenge to modern evolutionary theory. After all, if evolution can’t build something as basic as a new protein fold, how could it build whole new organs and body plans in the history of life? But Witt presents Axe with an objection: Axe couldn’t possibly have tested more than the tiniest fraction of a fraction of all the possible amino acid combinations for the protein he studied, so how can we trust his findings? Tune in to hear Axe’s explanation, and to learn about other lines of evidence confirming his research.
