Gaussian distribution should get bell-shaped curves. New studies of randomness in DNA from many animals now sequenced does not find that result. IT appears evolution is not random:-http://procrustes.blogtownhall.com/2010/03/17/gauss_ghost.thtml

This looks to be the usual creationist insistence that evolution is down to "chance" and nothing else. The process of "natural selection" is not random, it's a ratchet type process, so non-gaussian distributions are nothing untoward.

Even my favorite Massimo Pigliucci argues that evolution isn't random--especially when animal behavior can influence evolution. I say now (as I did when I came on this forum) that chance vs. design is a false dilemma.

GEORGE: This looks to be the usual creationist insistence that evolution is down to "chance" and nothing else. The process of "natural selection" is not random, it's a ratchet type process, so non-gaussian distributions are nothing untoward.-MATT: George is absolutely correct here. Even my favorite Massimo Pigliucci argues that evolution isn't random ... especially when animal behavior can influence evolution. I say now (as I did when I came on this forum) that chance vs. design is a false dilemma.-Round and round we go, though I guess that's the nature of this debate. George may be "absolutely correct", but Matt's conclusion seems to me to highlight the imbalance caused by such a selective argument. Two points, then, in an attempt to redress the balance: TO GEORGE: It has been acknowledged ad nauseam that natural selection is not random, but ... if I may echo you ... this looks to be the usual atheist insistence that evolution is down to "natural selection" and nothing else. The chance argument relates (a) to the origin of the mechanisms that made life and evolution possible, (b) to random mutations, and (c) to random changes in the environment to which the evolutionary mechanisms respond. Natural selection does not create anything new.-TO MATT: the dilemma of chance v. design, as far as I am concerned, relates principally to (a) above. I don't have a problem with the role played by chance once those mechanisms are in place, but we do not have one scrap of evidence that chance is capable of assembling them. Even if we ourselves were to create from scratch life, reproduction, senses, consciousness etc., (and it's a big "if"), we would only have proved that such creation requires intelligence. It might sway the balance of the argument for some of us, as might the discovery of other life forms elsewhere ... particularly if they have evolved as we have ... but the choice between chance and design will still depend on faith and not on fact. I would say, then, that the dilemma is only false to someone who has already made up his mind.

Some form of genetics with imbedded information to control and run the mechanisms of life. By definition life is made of organic molecules that can create energy to allow reproduction, by absorbtion of extracellar material. I think your point is specious.

By definition life is made of organic molecules that can create energy to allow reproduction, by absorbtion of extracellar material. I think your point is specious.-I'm just getting to the point now where say, one of the earlier papers we discussed... (this year, late last year?) where they created and posited a DNA-like structure that could devolve into what we have now is really starting to sink in. -We have it wrong. Completely. -I'm sure you've encountered this: You've been wailing away at the same problem for days. Everything seems "almost there" but your mind just can't connect the pieces. You shelve the problem for... hell, even nearly a year. You pick it up again and magically the answer stares you in the face. -I recently read an article from Bjarne Stroustrop, the inventor of C++ and in general, a living computer science legend. Commenting on the divide in computer science between academia and industry; one of his key observations is that (parap) "...when under this kind of pressure, academia turns in on itself and reverts to what it does best: pushing out small groups of like-minded individuals studying highly specialized problems." Combined with what you yourself have rightly criticized and our good ol' buddy Kuhn--we-have-it-wrong.-Studying life as it is now provides us with tantalizing clues, but I'm saying that it's essentially served all the purpose its going to serve. I'm utterly convinced of this. Creator or not--there IS a physical nature to how life got here, and outside of the greater debate here, THAT should be our focus.

I shan't go over the various arguments again, because the point at issue between us was your earlier statement that the chance v. design dilemma was false. I disagreed and still disagree, because in your response of 10 April at 00.58 you haven't actually addressed that issue. No matter what conditions may have been at the beginning, the fact remains that we do have life, and unless you subscribe to BBella's theory (there has always been life), either it originated by accident or by design. What follows on ... namely evolution ... from the origin of the mechanism for life, reproduction, adaptability and innovation can be made to fit into either pattern, and so I agree that you can't draw any sharp distinction from that point onwards.-In your post to David, you emphasize that "there IS a physical nature to how life got here, and outside of the greater debate here, THAT should be our focus." Unless people believe in magic (some do, but they don't include any of our current contributors), then that has to be an incontrovertible truth, since life on Earth is physical. Even God would have had to use physical matter to create physical life. And scientists are indeed focusing on THAT. But are we incapable of focusing on more than one subject at a time? David has offered us one post after another (e.g. his latest under "Why is a designer so compelling?") detailing the astonishing physical complexities of life. His conclusion that these provide evidence of design is not a distraction from the physical realities of life, or from the quest to discover their origin. Nor is George's conclusion that it's all down to chance and the laws of nature. Maybe, as you say, we won't "figure out the origin of life by studying life". But your argument concerning our ignorance of the conditions and forms that existed then applies to any approach to the subject. However, that shouldn't and fortunately doesn't stop us from studying life, from analysing and marvelling at what that unknown original mechanism has produced, and from speculating about how it could possibly have come into existence.

This is due to a mathematical fact--consider that we look at the entire string of chances that makes life exist. Life is some number in this context. If at any point on the line of its history, one of these events was completely random, than that number is permanently a factor, and its effect is greater and greater over time.

In the context of the conversation I'm speaking at large: what part of origin of life research has really come about by studying life itself? I'm not saying that we can't draw inspiration, or use life as a guideline, but the origin of life itself could very well be something entirely different than what we have now. My thought is more of a warning that if we place too much emphasis on life as we know it now, we may completely miss some other, more likely method than what we've seen. The paper I posted some time ago that talked about a "de-evolution" if you will of a codon base is what really got me thinking this direction. -I've said before that a good chunk of my work here is "as a mathematician," and it is in this sense that I view my job as one of pointing out heuristics and feedback on current methods and thinking. I think the approach currently taken in origin of life research is completely wrong. The goal should be to create life--any kind of life, even if it doesn't resemble our own--and then work from THAT point. Marveling about life is contemplative, creating it is actionary.

The question "how much is chance, and how much is design?" therefore becomes as irrelevant as a girl protesting her innocence because she is only slightly pregnant.

If the quest is for "the truth", you have argued that we can never know the original conditions or forms, in which case we can never be sure that what we invent/discover will be "the truth" anyway.

In this (as in many questions) I'm a fairly staunch perspectivist. First, the question on creating life.-Biology in all its forms has given us--quite clearly--the benchmark by which any artificial creation of life needs to achieve. Studying existing life at this point can fill in some gaps, but it is too... reactionary in its approach. It relies on someone needing to go out and find some bit of life and then to study it. -My computer science background tells me explicitly--to understand something--to truly understand something, you need to build it. Anything less is--in my opinion--incomplete. In my mind the research direction needs to move away from biology in this field and towards experimental chemistry. Too few people work in this area. -Why do I want to know the origin of life? I truthfully submit that I will not know the answer to origins. But I want to know any and all of the potential processes that may have given it to us, in my case because we need the technology. We have a limited life on this planet, and we need to get off of it purely for survival's sake. The power to engineer life is one that will allow us to colonize worlds we would never have dreamed of otherwise. -Philosophically I've had a unique path. I've been a theist, atheist, and now agnostic. And I recognize at each point that I was able to argue convincingly for each position, which informs me that--very likely--there is no true position. There's one painfully honest one. But no one likes to admit they can never know. And in my framework, knowing trumps everything.

If your motive is to prepare us for mass evacuation, I'd have thought that when the time came, we would need to know how to adapt our own form of life to different conditions rather than how to engineer different forms! If we can't reproduce ourselves normally on Planet Z, there seems to be little point in going there, but if it can sustain us, it should be able to sustain other forms of earthly life as well. I suspect that logistics may turn out to be more of a problem than "engineering life". -Earlier you say that "to truly understand something, you need to build it". Others might say you need to truly understand something before you can build it.-MATT: Philosophically I've had a unique path. I've been a theist, atheist, and now agnostic. And I recognize at each point that I was able to argue convincingly for each position, which informs me that--very likely--there is no true position. There's one painfully honest one. But no one likes to admit they can never know. And in my framework, knowing trumps everything.-There does have to be an ultimate truth, but like you I've been through the three ...isms and am no nearer knowing what that truth is. I don't find it painful any more, though, and have no qualms about admitting my ignorance. I'm only roused when I'm confronted by intolerance and arrogance, but generally so far we've been fortunate to escape this on our forum. I should add that for me personally, the exchanges with yourself, David, George, BBella and others who have come and gone have been a genuine education, but I don't expect my hand will ever hold the trump card of "knowing".

I'll still stick with Adler. There can be proof'beyond a reasonable doubt'. I'm already there, and I think it is reasonable for each person to have such a point.

> I seem to remember you saying once that mathematicians think differently from everyone else! The point of the chance v. design debate is to ascertain whether there may or may not be/have been a designer. Atheists believe that the original mechanism for life, reproduction, adaptability and innovation came about by chance. Most theists believe it was designed by God. Black and white. However, even with your scenario, my non-mathematical, agnostic mind has to ask you: "if at any point on the line of its history, one of these events" was designed, doesn't that mean there has to be/have been a designer? The question "how much is chance, and how much is design?" therefore becomes as irrelevant as a girl protesting her innocence because she is only slightly pregnant. If there is ANY design, there is/was a designer. The very real dilemma is therefore still between chance and design, not between proportions of each. -My thesis has ALWAYS been, without Matt's math niceties: the more complicated the mechanisms of life's controls become in our research findings, the less likely chance did it. Life IS complicated, and more so every day as new research appears. This article explains:-http://www.nature.com/news/2010/100331/full/464664a.html

Couldn't get in to read this, (site's broken or down) but the Google tags said "The Procrustean by Rob, Political Blogs, Conservative Bloggers, The Republican Blogspot, Political Blogging, and More."-How does his ideology impact his views? Why should I trust his opinion more than PETA, my old biochem profs, or IPCC? Anyone posting "science" in a political blog can be automatically discounted. -Anyways, probability distributions are intimately tied with the very specific sets of data they are supposed to explain--and with the same data points you can try different distributions just as another experiment. So, even if what he's showing isn't Gaussian, it means nothing if a verifiable correlation cannot be found to explain it.
