Origin Of Life

You: a trillion tiny random machines

In “How You Consist of Trillions of Tiny Machines,” a review of two books, Australian palaeontologist Tim Flannery encapsulates the problem facing origin of life studies. Assessing Paul Falkowski’s Life’s Engines: How Microbes Made Earth Habitable, he notes, Today, driven by ongoing technological innovations, the exploration of the “nanoverse,” as the realm of the minuscule is often termed, continues to gather pace. One of the field’s greatest pioneers is Paul Falkowski, a biological oceanographer who has spent much of his scientific career working at the intersection of physics, chemistry, and biology. His book Life’s Engines: How Microbes Made Earth Habitable focuses on one of the most astonishing discoveries of the twentieth century—that our cells are comprised of a series of Read More ›

Emergence as an Explanation for Living Systems

Yesterday I watched a re-run of a Star Trek: The Next Generation episode. There. I said it. I love Star Trek. Notwithstanding the many absurd evolution-based plotlines. In this specific episode, Data referred to a particular characteristic of a newly-developing lifeform as an “emergent property.” I’ve looked into the “emergence” ideas in the past, and the related self-organization hypotheses, and have never been too impressed. But it has been a while, so I thought I’d quickly navigate over to the Wikipedia page on the subject to see what it says. Now I’m a big fan of the general concept behind Wikipedia and it is a very useful tool, if used properly. Yet everyone knows that Wikipedia is a questionable source Read More ›

RNA World worst hypothesis but for all the others?

Further to: Biochemist: Is RNA world wrong after all? (As noted before, if we really wanted researchers not to find out how life originated, we would urge that they continue with full-bore Darwinism), from BioMed Central, we learn from biochemist Harold S. Bernhardt: The RNA world hypothesis: the worst theory of the early evolution of life (except for all the others) Abstract:The problems associated with the RNA world hypothesis are well known. In the following I discuss some of these difficulties, some of the alternative hypotheses that have been proposed, and some of the problems with these alternative models. From a biosynthetic – as well as, arguably, evolutionary – perspective, DNA is a modified RNA, and so the chicken-and-egg dilemma of “which Read More ›

Biochemist: Is RNA world wrong after all?

Remember when RNA world just had to be true, in that multiverse/global warming/Darwinism way? Where the observer soon realizes that evidence is superfluous—is even a threat? According to many origin of life researchers, RNA world (RNA preceded DNA and once did its job) has had that status for some time now among science writers. Well… From New Scientist: Why ‘RNA world’ theory on origin of life may be wrong after all Note: We are told, “Registration is required to view the article.” Not only that, but one can’t now even preview the first two graffs from the article before signing up for something. That said, a friend who did sign up offers the salient point: At some point, the idea Read More ›

Louis Pasteur on life, matter, and spontaneous generation

From the BBC: Few people have saved more lives than Louis Pasteur. The vaccines he developed have protected millions. His insight that germs cause disease revolutionised healthcare. He found new ways to make our food safe to eat. Pasteur was the chemist who fundamentally changed our understanding of biology. By looking closely at the building blocks of life, he was at the forefront of a new branch of science: microbiology. Here, from a letter to an atheist: Science brings men nearer to God. Posterity will one day laugh at the foolishness of modern materialistic philosophers. The more I study nature, the more I stand amazed at the work of the Creator. I pray while I am engaged at my work Read More ›

E coli hybrid copes with 700 mya engineered gene

From Quanta Magazine: Several years ago, Eric Gaucher, a biologist at the Georgia Institute of Technology in Atlanta, even resurrected a 700-million-year-old protein from E. coli. Now, in a new twist on paleogenomics, Kacar has engineered that ancient protein into modern E. coli and tracked how the microbe adapted to it. The new approach, which Kacar presented yesterday at NASA’s Astrobiology Science Conference in Chicago, provides a more integrated view of the mechanisms of evolution — for example, how a protein’s position in a broader network influences its rate of change or how protein networks evolve as a whole. They seem to have a mind of their own. Kacar then synthesized that gene and inserted it into E. coli in Read More ›

We are trillions of tiny machines

From Mars. According to a paywalled review in New York Review of Books: Today, driven by ongoing technological innovations, the exploration of the “nanoverse,” as the realm of the minuscule is often termed, continues to gather pace. One of the field’s greatest pioneers is Paul Falkowski, a biological oceanographer who has spent much of his scientific career working at the intersection of physics, chemistry, and biology. His book Life’s Engines: How Microbes Made Earth Habitable focuses on one of the most astonishing discoveries of the twentieth century-that our cells are comprised of a series of highly sophisticated “little engines” or nanomachines that carry out life’s vital functions. It is a work full of surprises, arguing for example that all of Read More ›

“Do Life and Living Forms present a problem for materialism?”

An essay contest from the Royal Institute of Philosophy and Cambridge University Press Entrants could win £2,500, publication in Philosophy, and a half hour of fame. No, but seriously, they could contribute to an increasingly significant discussion. Old style vitalism, attributing an internal animating substance or force to living things gave way to the idea that life may yet be a property over and above physical and chemical ones. Subsequent to that it was widely thought that life is an organisational or functional feature of bodies instantiated by their physical properties. With ongoing debates about analogous issues relating to mind (especially consciousness and intentionality) still running, and renewed interest in anti-reductionist interpretations of emergence and of teleological description and explanation Read More ›

Best origin of life quotes from 2015?

Rabbi Moshe Averick is comprehensively revising Nonsense of a High Order: The Confused, Illusory World of the Atheist (Mosaica Press). He asked if I know of interesting citations from 2015, explaining that he has put quotations in chrono order going back to 1934. If readers can help, please put the quotes with links in the comments box. I’d suggest looking at some of Suzan Mazur’s recent work at the Huffington Post, including Origin of life: Highlights of Suzan Mazur’s interview with researcher Corrado Spadafora and Suzan Mazur: A non-linear language needed for life? Meet Luis Villareal Her book, The Origin of Life Circus is an excellent source as well. There might also be something here. The Science Fictions series at your Read More ›

15 open questions posed on origin of life

By working scientists. A friend writes to tell us: The International Institute for Advanced Studies (IIAS) (Web) Kizugawa, Kyoto, Japan, has proposed 15 open questions on the origin of life: 02. Why is the origin of life still a mystery? Premise: Why is the origin of life still a mystery? Yes, we all in science accept 1924 Oparin’s idea that life on Earth originated from the inanimate matter via a series of chemical steps of increasing molecular complexity and functionality. However, the turning point nonlife-life has never been put into one experimental set up-actually it has never be clarified this from a conceptual point of view either. There are of course several hypotheses, and this plethora of ideas means already Read More ›

Missing link in origin of life confirms Mike Behe’s thesis?

Irreducible complexity From Yahoo News: The new research — which involves two studies, one led by Charles Carter and one led by Richard Wolfenden, both of the University of North Carolina — suggests a way for RNA to control the production of proteins by working with simple amino acids that does not require the more complex enzymes that exist today. This link would bridge this gap in knowledge between the primordial chemical soup and the complex molecules needed to build life. Current theories say life on Earth started in an “RNA world,” in which the RNA molecule guided the formation of life, only later taking a backseat to DNA, which could more efficiently achieve the same end result. Like DNA, Read More ›

FYI-FTR: Part 8, an objection — >>nobody has solved the OOL challenge from an ID perspective either. And they never will until ID proposes the nature of the Designer (AKA God) and the mechanisms used (AKA “poof”). >>

The captioned comment comes by way of an email, from YM: >>nobody has solved the OOL challenge from an ID perspective either. And they never will until ID proposes the nature of the Designer (AKA God) and the mechanisms used (AKA “poof). >> (In addition, I have received a slander-laced remark from one of the denizens of the circle of hostile sites that confirms on the ground stalking and includes implicit threats. Duly shared with appropriate authorities. This sort of uncivil reaction strongly suggests that this series is having an impact.) The response as headlined indicates that there is now an attempt to shift the burden of warrant to ID regarding OOL. This, we will now address, first pausing to Read More ›

Stuart Newman: Non-linear evolution

Suzan Mazur continues to impress, as a science writer who is seriously trying to understand origin of life questions. Her recent book is The Origin of Life Circus, much recommended by Uncommon Descent News if you want to get up to speed on the questions. Here is her interview with Stuart Newman on non-linear evolution: It was Stuart Newman who was the first of the Altenberg 16 scientists I discussed developments with following the Extended Synthesis symposium in 2008 at Konrad Lorenz Institute, a meeting I was barred from attending for having gotten out in front of the event with a series of stories and an e-book — showcased on these pages — in which I interviewed evolutionary thinkers who Read More ›

Senior NASA origin of life scientist on a research thesis that smacks of “creationism”

Readers may remember Suzan Mazur’s interview with a senior NASA scientist: senior NASA origin of life scientist: In a couple of e-mails to me in January 2013, Andrew Pohorille, the senior-most scientist at NASA working in the origin of life field, objected to my story, “The RNA World’s Last Hurrah?”, “The RNA World’s Last Hurrah?”, in which I interviewed Paul Davies’ collaborator at Arizona State University, physicist Sara Walker. … Hey, we got you hooked? Then how be this, a followup: Pohorille is now even less enthused about the RNA world since Princeton and said there were also fewer scientists currently pursuing that line of research. He also thinks the answer to origin of life is not about a thermodynamic Read More ›

Unsolved problems in biology

From Real Clear Science: When biologists get together to discuss the nagging mysteries in their diverse field, there’s always that elephant in the room: How did life spring up from non-life? But, according to highly regarded cancer researcher Robert Weinberg, it’s an elephant that most biologists ignore, or at least discreetly avoid. “Origin of life is not something people work on that much because it’s so far away from resolution.” Instead, biologists turn their attention to other problems, fruits that hang a bit lower on the tree. Though these queries may not be of existential interest, they’re no less fascinating. Your Nobel? Here’s one: It is a beautiful irony that the smallest of creatures is at the center of one Read More ›
