Leslie Orgel: Metabolic Origin of Life “Unlikely”; Complexity Requires “A Skilled Synthetic Chemist” (Part 2)
In Part 1 I discussed the eminent and late origin of life theorist Leslie Orgel’s criticisms of theories that self-sustaining metabolic pathways could spontaneously come into existence on the early earth and evolve into life. Orgel’s was skeptical that this could occur because “the chance of a full set of such catalysts occurring at a single locality on the primitive Earth in the absence of catalysts for disruptive side reactions seems remote in the extreme.” Indeed, according to Orgel, the type of complexity we normally find in the metabolic pathways of life require “a skilled synthetic chemist.” But what if we assume that such pathways could come into existence? Even if such pathways existed, they would still be far from Read More ›
Leslie Orgel: Metabolic Origin of Life “Unlikely”; Complexity Requires “A Skilled Synthetic Chemist” (Part 1) (Updated)
Last year I blogged about Robert Shapiro’s excellent article in Scientific American that gave cogent critiques of many standard models of the chemical origin of life. Shapiro critiqued the view that a primordial soup existed on the early earth that ultimately gave birth to a self-replicating molecule, which eventually evolved into RNA and then DNA. After critiquing this standard model, Shapiro gave his alternative explanation, proposing that life evolved from metabolic pathways that naturally occurred on the early earth. As I wrote at that time, Shapiro “gives scant explanation for how these life-like metabolic networks can come into existence naturally, and he gives no details as to how these thermodynamic states produce real life–life as we know it today.” Now Read More ›
Leading Biologists Marvel at the “Irreducible Complexity” of the Ribosome, but Prefer Evolution-of-the-Gaps
A roundtable symposium was recently held at by John Brockman entitled, “Life: What A Concept!” discussing how life arose. Participants included some huge names in origin of life research and genomics, such as Freeman Dyson, J. Craig Venter, George Church, Robert Shapiro, Dimitar Sasselov, and Seth Lloyd. None of the participants are favorable towards intelligent design, but the transcript of their conversations suggested that the ribosome may exhibit “irreducible complexity” (their words). It’s clear that these anti-ID scientists don’t even understand exactly how life works, much less do they know how it arose naturally, but that they are nonetheless taking an evolution-of-the-gaps approach, assuming that complex micromolecular machines like the ribosome will (despite their present appearances) indeed turn out to Read More ›
A Point of Light
Charles Darwin’s theory of evolution is a religious theory in the sense that it is based on powerful theological claims. Over the past four centuries these beliefs have influenced and even dominated science, and if anything have grown even stronger since Darwin. They form the foundation and ultimate justification for today’s theory of evolution. As evolutionist Ken Miller rhetorically asked, would God “really want to take credit for the mosquito?” Evolution, in one form or another, must be true. But theists are not the only ones using religion to mandate this rigid form of naturalism. Ironically, religious skeptics are just as capable of making God-wouldn’t-create-the-species type arguments. David Hume is a well known historical example, though many of his ideas Read More ›
Darwin Day in America “superbly makes the case that Darwin had plenty of bad ideas”
Over at Culture Watch, American born, Melbourne living, blogger Bill Muehlenberg provides yet another good review of John West’s Darwin Day in America. ‘Social Darwinism’ is a term which refers to the social and political ramifications of biological Darwinism and the materialism which it is imbedded in. Darwin regarded humans as basically higher animals, and as the social sciences became more and more tinged by the Darwinian outlook, humans increasingly began to be treated as mere animals, or machines. This volume looks at how the materialistic worldview of Darwinism has impacted on a wide range of fields. As academics, scientists and politicians apply the Darwinian view of man to various social sciences, some very negative outcomes have ensued. We have Read More ›
