deNovo's bioprocess | from Jan Martel | Thu, 29 Sep 2005 11:08:57 -0400
Mr Klyce, I am really interested in the bioprocess of Douglas Robinson about the emergence of bacteria from eukaryotic cells. I would like to know if you are aware of any details concerning this work, replication or results... I have exchange a few times with Mr Robinson, but I think more people should get involved to potentially validate these revolutionary results as they seem to justify further study in the bacteria so often seen in cancer. Best regards.

thermodynamic entropy when two gasses mix (2nd try) | from Brig Klyce
(In case this did not get through earlier. Any help will be appreciated. Thank you!!...) Dear Sirs -- On my webpage about evolution and the second law of thermodynamics, I write, "In the diffusion of heat, the entropy increase can be measured with the ratio of physical units, joules per degree. In the mixing of two kinds of gasses already at the same temperature, if no heat is exchanged, the ratio of joules per degree - thermodynamic entropy - is irrelevant." Now Sergio Rossell claims that I am wrong, and that the entropy gain can be calculated without resort to little volume elements.... I would like to know more about this. Can either of you comment? Thank you!! ...Best regards. Brig

From Sergio Rossell | Wed, 28 Sep 2005 02:34:48 -0500 (CDT) Dear Brig and Shu-Kun, Thank you for this exchange. Shu-Kun writes that the claim "In the mixing of two kinds of gasses already at the same temperature, if no heat is exchanged, the ratio of joules per degree thermodynamic entropy is irrelevant" but gives no reference, we need to rely on his authority alone, this of course is unsatisfactory. I have given you a specific example and reference to literature (Physical Chemistry by Ira Levine, 1995) supporting my claim and describing the experiments. Best wishes, Sergio
From Brig Klyce | 09:22 AM 9/28/2005
Dear Sergio -- Shu-Kun asked me to remove his reply. He declined to give a reason and asked not to be contacted again.... Under these circumstances, I wouldn't blame you for being sceptical. My own further thought is this. You said partial pressures can be measured using semi-permeable membranes. But it sounds to me more like this: semi-permeable membranes can be used to separate mixed gasses, whose pressures can then be measured. Besides, if there's a gain when they're mixed, there would have to be a loss when they're separated again, right? So the membrane would violate the law, like Maxwell's demon! I'll try to look at your reference. Best regards. Brig
From Sergio Rossell | Wed, 28 Sep 2005 14:31:09 -0500 (CDT) — Dear Brig, I have the impression that the discussion inspired an idea in Shu-Kun's mind that he believes is very important and wishes not to share.... Now to the interesting stuff. [You wrote] ...semi-permeable membranes can be used to separate mixed gasses, whose pressures can then be measured.
Your rewording is confusing to me. Semi-permeable membranes can be used to measure partial presures because one gas hits against them while the other passes through, its a litte bit like filtration. Semi-permeable membranes can be used to separate gases but not without work, you have to compress the gas the memebrane is impermable to.... You need to invest work to separate them. Maxwell's demon is an important thought experiment.
I'll give you an alternative account, which as far as I know is originally mine. It is very simple: physics is based upon observation, there is no logical necesity for the most basic physical principles, logic does not require energy to be conserved nor the speed of light to be constant, it just happens to be so. The theory of probabilities is the formalization of the logical consequences of what will happen if, for instance, a molecule is as likely to move to the right as it is likely to move to the left, it later can be extended to biased probabilities, and so on. The second law of thermodynamics is a principle that was discovered, there is no logical need for it to be so, it just is so, as far as we can tell. If you introduce Maxwell's demon you introduce a biased probability, you change the rules of the game. If you change the rules you need not to have the same game, you may ask how would a change in that rule still allow the game to remain unchanged, and then you will have answers as that given by Szilard.
I googled the following search: thermodynamics entropy mixing site:.edu And found a site that calculates the entropy of mixing in the same manner as the book I have. http://www.chem.arizona.edu/~salzmanr/480a/480ants/mixing/mixing.html ...Best wishes, Sergio
From Klyce | 11:01 PM 9/28/2005 — I suspect Shu-Kun noticed the word panspermia and had an anxiety attack. My overall point about entropy is that the concept is confusing and cannot be used to explain how sunlight can ultimately compose genetic programs. I believe this point -- the concept is confusing -- is reconfirmed in our exchange. Originally attempting to locate the source of the confusion, nine years ago I wrote that mixing doesn't increase J/K. This statement on my website went unchallenged until now, when you say yes it does. I asked another opinion from the publisher of Entropy. He says it doesn't. Confusion reconfirmed!
BTW, another expert recently told me on the phone that mixing does increase J/K, but he thought the calculation would require using the little volume elements. I am certain that using Boltzmann's constant on quantities derived from the volume elements is a logical error, easily demonstrated. For an authority how about Claude Shannon, who wrote, with respect to the parcelling, "In the continuous case the measurement is relative to the coordinate system. If we change coordinates the entropy will in general change." All that said, I should confess, you have shaken my confidence about the mixing. Maybe it does increase J/K? (You have definitely earned a free _Mathematics of Evolution_ by Fred Hoyle!)
[You wrote] Semi-permeable membranes can be used to separate gases but not without work, you have to compress the gas the memebrane is impermable to. As I recall from high school chemistry, in liquids, a semi-permeable membrane can separate things across a barrier when the initial pressures are equal on both sides. The separation can produce a pressure difference, causing cells to burst, for example. Would gasses be different? I am at the very edge of my knowledge here! Thanks for your continuing interest. Best regards. Brig
From Rossell | Thu, 29 Sep 2005 02:48:58 -0500 (CDT): — Dear Brig, I agree that thermodynamics alone cannot explaing how sunlight can drive the evolution of complexity, but that claim has not been made, as far as I know, by any serious scientist. The production of entropy is, to my eyes, no more and no less than an observation that we find over and over again. The production of entropy was related by Boltzman to the idea of probability distributions. Based on the assumption that molecules are as likely to move in one direction or the other you can (considering a huge number of molecules) derive the same behavior predicted by entropy production as Carnot stated it. Boltzman gives a very plausible mechanism for Carnot's finding (clasical thermodynamics never gives a mechanism for entropy production)
[You wrote] ...Confusion reconfirmed! I don't think that thermodynamic entropy is confusing, the confusion arises because some people have confused thermodynamic entropy with "disorder", entropy is well defined in statistical mechanics, disorder is not. The confusion with logical entropy is similar, it arises from given the same name to a different thing. Thermodynamic entropy is a characteristic of the physical world, logical entropy is defined in similar mathematical form, but its defined in a "virtual world" of information that needs not ot be geverned by the same laws of the physical world.
[You wrote] ...how about Claude Shannon, who wrote, with respect to the parcelling, "...If we change coordinates the entropy will in general change." I am not very found of authorities, and I am not an expert in information theory. But what you say about Shanon that entropy changes relative to the coordinate system may be so in his information theory but is incompatible with known physics. It violates one of the most fundamental principles of physics that of the conservation of linear and angular momentum, if Shanon's idea of entropy would be true for the physical world, Newtonian dynamics and Einstein's relativity would not have been discovered but other laws of physics would have taken their place (see for isntance Feynman's lectures on physics).
[You wrote] ...Would gasses be different? You remember your highschool teachings well, what you are refereing to is osmotic presure one of the colligative properties. This example you give is different becuase in here both components do interact (which was different in ideal non interacting gases of the mixing example). The issue is a bit involved with thermodynamics, the basic idea is that the internal energy of a solution changes with the addition of solute. It's been a pleasure to have this series of discussions with you, I have had to revisit my physics and physical chemistry books to keep up with the discussion, and I have enjoyed the experience very much. Best wishes, Sergio ...Sergio Rossell | Department of Molecular and Cell Physiology | Vrije Universiteit Amsterdam | http://www.wichizaya.demon.nl/
09:50 PM 9/29/2005: We didn't resolve every issue, but I enjoyed it....Thanks. Brig
03:35 AM 9/30/2005: I'm very busy finishing my thesis, but will come back to these issues form time to time. I plan to work a bit on my web site, yours has inspired me to put my thoughts in a coherent manner and share it with whoever finds it.
I have failed to express how much I have benefited form our exchange. Although I do not agree with all your thoughts and I do not embrace panspermia as a working hypothesis just yet, I have been inspired by your efforts and passionate discussion, and particularly now feel I should follow your lead in sharing thoughts with others. I believe we will have future contacts and intersting discussions....
08:54 AM 9/30/2005: I am still thinking about our problem! I do not doubt your math, but perhaps the philosophy behind it. Entropy in the thermodynamic sense is defined as unavailable energy. It increases because the ability-to-do-work has decreased. In the example with the two gasses, what ability-to-do-work did they have before mixing, which was lost after the mixing? Suppose they were gasses not separable by a semipermeable membrane (gasses of equal molecular weight?)...
From Rossell | Wed, 5 Oct 2005 03:29:30 -0500 (CDT): Hi Brig, I was out of town for a few days. Entropy is defined as the heat transfered during a reversible process divided by the absolute temperature. Its relation to work is given by the Gibbs equation: ds= (dU+PdV)/T For a closed system with no chemimal reaction. Capacity to do work does not imply that work is actually done. You can use electrical energy to drive a motor and lift a body or you could produce only heat by making it circulate through a resistence.
09:16 AM 10/5/2005: Right, but the entropy gain is greater in the latter case, right?
In mixing, the fact that you could do work if you would use a semipermable membrane, does not imply that the process cannot occur without doing any work.
1) What work could you do with the unmixed gasses?
2) If they were not separable with a semipermiable membrane, what work could you do?
If you want to understand this matter you will need to spend some time studying basic thermodynamics. Do not be fooled in thinking that anyone can understand basic thermodynamics by having only a brief exposure during a highschool or university course. It is necessary to keep on studying it. I wrote a very short summary of what I have understood upon the matter (http://www.wichizaya.demon.nl/work/Thermo.pdf) but it is very dry and has moslty equations and little text. I am not finished with it but, as far as I can tell, all definitions are precise. I suggested revisiting your thermodynamics book because I think you will benefit form it, and because I believe that difficult matters, such as thermodynamics, can only be learned by repeated exposure. I remain open for discussion and interested in your point of view. Very best wishes, Sergio
Wed, 5 Oct 2005 13:56:17 -0500 (CDT): Dear Brig, I suggested you to study thermodynamics not becuase I'm annoyed, but because I think you are very interested and that without patient study you might not achieve understanding it.... The entropy change depends solely upon the initial and final states of the system, it matters not whether the free enegy change was used to perform work or just dissipated as heat. Inefficient machines do not 'create' more entropy per unit energy invested than efficient ones, but they do less work.
As I argued in one of our first exchanges, in order to mix, gases must first expand, this expansion can be in principle used to lift a body by ussing semi-permeable membrane.... Gases are separable with semi permeable membranes, but work must be invested to separate them. What is not possible is spontaneous separation of gases by just placing an semi-permeable memebrane in the chamber.
11:05 PM 10/5/2005: [You wrote] You can use electrical energy to drive a motor and lift a body or you could produce only heat..... In the former case, the weight can descend again and do work; in the latter case not. I am pretty sure there's more entropy gain in the latter example. Can you do a calculation? Say 1kwh is expended in each case. In the former case half the energy is lost as heat, and the other half is converted to gravitational potential energy. In the latter case it all is lost as heat. Experiments done at 300K. Isn't the gain .5kwh/300K versus 1kwh/300K?
OK about the separable gasses. For the non-separable ones, I think you already answered my question when you wrote (28 Aug): If, however, gas A and B cannot be distinguished, then the delta S would not change. I should have paid more attention. I think the gasses issue is settled. Now the other one!
From Sergio Rossell | Sun, 9 Oct 2005 05:28:45 -0500 (CDT): Dear Brig, I received the book Mathematics of Evolution, thank you very much, I will read it with care.
[You wrote] Isn't the gain .5kwh/300K versus 1kwh/300K? The entropy of the SYSTEM depends solely on the intial and final states. Importantly, if the system is not isolated you can think of three entropy changes: (i) the system's entropy change, (ii) the surroundings entropy change and (iii) the universe's entropy change. For any process to proceed the latter must increase (or stay constant in idealized reversible processes). Whether the system changes form state A to B in a reversible or irreversible manner does not affect the system's entropy change, but does affect the amount of heat transferred to the surroundings, and when these are considered big enough and at the same temperature the amount of heat transferred divided by the temperature is the entropy change in the surroundings. So you are right in saying that the entropy production is greater in the case transforming electrical energy into heat (considering that initial and final states of the system are equal to those when the system does work), becuase you are refering to the "universe". I was confused and thought you were talking about the system (my bad). This distinction is important because it allows the decrease of entropy in a closed system, if work is invested upon it, while the entropy of the universe increases.[...]
Very glad that the gas issue has been settled! The other issue is, to my eyes also settled, when I first read your email I was thinking upon the system while you were talking about the "universe". We actually agreed form the begining, I just didn't notice. Very best wishes, and thanks again for the book... Sergio

The Nylon Problem | from Ron McGhee | Fri, 23 Sep 2005 11:37:49 -0400
B- Has the Nylon Problem, as described in Space.com article linked below, been addressed somewhere in your website. I would very much like to read it. -R
http://www.livescience.com/othernews/050923_ID_science.html
from Brig Klyce, 09:37 AM 9/23/2005: Ron -- this will be brief but I think that nylonase is probably close to other existing enzymes and could have easily come by microevolution from one of them. Not a hard thing for darwinian evolution to do, but very different from the invention of new programs. The darwinian claim -- that it accounts for all new genetic programs -- is an extraordinary one to me. I believe the evidence should also be extraordinary. If the nylon problem is supposed to be the clincher, I'm unimpressed.
the "software" aspect | from Ken Jopp | Thu, 22 Sep 2005 17:15:06 -0500
Hi Brig. Hope you're well, but I have a bone to pick with you. I'm sympathetic to the panspermia argument, but sometimes I think the peripheral issues you pursue on the site lead to blind alleys. Case in point: this excerpt from your comments on the book by Robert Hazen: "Most interesting to us, however, is that a book about the origin of life, by 'one of the world's foremost scientists seeking answers to these questions,' can deal with hardware (chemistry) only and completely ignore the software aspect of the problem." Other places on the site you also refer to the "software" aspect of the problem.
What is this mysterious aspect of the problem? Genes are arrangements of atoms, or "hardware." Presumably by "software" you're referring to the "information" that resides in the arrangements of atoms. But there is no such entity as "information" in arrangements of atoms, no matter how complex the arrangements. Information exists only in minds. Minds can perceive arrangements of atoms and notice patterns, correlations, etc., but that information exists in the perceiving mind. The atoms just are where they are. To store an encyclopedia on a computer chip is not to imbue the chip with information but only to rearrange the atoms. If there were no minds to recognize patterns in the arrangement and perceive meaning in it, there would be no information, just one particular arrangement of atoms instead of another.
If nothing else, you're making metaphysical assumptions or getting chummy with the Intelligent Design people. You're not doing that, are you? ...Best, Ken
from Brig Klyce, 06:24 PM 9/22/2005: Dear Ken -- Thanks for paying attention! You have identified a core issue. The software aspect is the crux of the matter, I believe. (And I assure you, the creationism/ID advocates consider me almost as reproachable as the hardcore darwinists do.)Software has always been critical to my argument. By software I mean programs, subroutines and algorithms encoded in strings of symbols like bits or nucleotides. You say, "Information exists only in minds." But I think there is a clear difference between, for example,
-- blazes on trees that denote the trail, versus scars on trees that falling limbs made.
-- instructions written in text versus a random sequence of characters.
I will grant you, if no one ever sees the blazes or instructions, they are useless. But if anyone ever does see them, they would have a use and purpose. That is true about them now, whether we know it or not. Also,
-- the genome of an animal or plant versus a random sequence of nucleotides
is the same. The former, but not the latter, has a use and purpose, independent of our knowledge.
To continue, I suspect that programs, subroutines and algorithms encoded in strings of symbols do not get composed by darwinian processes. They can get optimized, diversified, made incompatible with others (speciated), randomized, etc. But not composed. If they exist, powerful genetic software management may be able to reconstruct them from large fragments. (With a little programming, MS Word could probably use its syntax and spellcheck features to reconstruct The Declaration of Independence from a small number of randomly sliced, shuffled pieces.)

Carbonate discovered in Tempel 1 from Deep Impact mission.
from Robert Clark | Sun, 18 Sep 2005 10:21:34 -0400 (EDT)
On the space oriented bbs uplink.space.com someone mentioned the detections of olivine in Tempel I and previously in other comets raise the possibility of more heating in comets than would be expected for objects formed far from the Sun. This would also be consistent with the theory of radiogenic heating in comets:

"We know that these dust grains change from amorphous to crystalline as they are heated, and our laboratory research revealed that the rate at which they change is extremely sensitive to temperature," Nuth added. "At the very low temperatures, where water-ice and the other volatile components of comets are frozen, the time required for amorphous silicate dust grains to change to the crystalline olivine found in comet Halley is many times longer than the age of the Universe."
http://spaceflightnow.com/news/n0007/20cometdust/
So there at least three separate and independent indications of internal heating, likely radiogenic, in comets: carbonate/clay detected in Tempel I, olivine in Tempel I and other comets, and crystalline ice detected deep in the Kuiper belt:

The Wheel... | from Ron McGhee | 12:31 PM 9/14/2005
Brig- Are you surprised that organic compounds were found in a 'comet'... Honestly, I've been in and out and up and down articles, journals, text books, and your website and haven't seen any data presented that discounts the basic tenants of the theory of Panspermia... I've seen theoretical arguments against it... but no hard data to refute the thesis... It's really amazing to see how slowly the wheel is turning towards this theory, despite the steady stream of convergence of findings. Maybe it is just grinding finely... Best Regards, Ron

upon panspermia/second law | from Sergio Rossell | Sat, 27 Aug 2005 12:06:41 -0500 (CDT)
Dear Sir, I have bumped into your web site very recently and enjoyed very much your discussion upon thermodynamic and logical entropy. I found very enlightening your accounts of entropy definition (or perhaps the lack of it) in information theory, and I do agree with you that evolution has produced ecosystems of increasing complexity. There are, however, two points which were not clear to me. (i) You wrote: "the mixing of two kinds of gasses already at the same temperature, if no heat is exchanged, the ratio of joules per degree - thermodymanimc entropy - is irrelevant." I do not understand how could you mix physically distinguishable gases without creating thermodynamic entropy. Although reversible mixing can be conceived (which indeed would be isoentropic), the only way to have the gases separated (prior mixing) is to have them in different volumes. This implies that the partial pressure of one gas, say A, will be pA in compartment I and 0 in compartment II, while for the other gas, say B, will be 0 in compartment I and pB in compartment II. The consequence of this is that once you remove the barrier separating the compartment, gas A will expand to fill compartment II and gas B will expand to fill compartment I, this is, you will have isothermal expansion and therefore heat flowing into your system.
Brig Klyce replies | 04:29 PM 8/27/2005: If you had only one gas expanding into a second empty chamber, maybe so. But I do not think heat or work must be supplied in order for the two gasses to mix.
You could avoid the expansion only by compressing the systems (i.e. investing work). At risk of boring you with formalism, delta S=-nA*ln(xA)-nB*ln(xB), where nA and nB are the moles of A and B respectively and xA and xB their molar fractions. I am aware that this detail by no means solves the confusion between logical and thermodynamic entropies, but is perhaps an interesting point.
I can easily picture this mixing with no work supplied. Two cylinders connected by a hose with a valve separating them. Simply open the valve. In time the gasses will mix.
The second confusion I had was that after convincing the reader of the discrepancies between logical and thermodynamic entropies you conclude that we should admit that earth’s biological system is open to organizing input form the outside. If logical entropy is not the same as thermodynamic entropy, then the second law (entropy must increase in a closed system) needs not to be valid for logical entropy. We have no reason to believe that it will increase if the system is isolated in terms of order. Your claim is of course plausible, but is it proven?
My claim, that organization cannot spontaneously increase, or, logical entropy cannot decrease in a closed system, is not proven. It is merely plausible to me (and most adults in the US.) Likewise, the opposing darwinian claim that organization can increase spontaneously, is unproven. This seems completely obvious to me. If darwinians say that their claim is proven by the big bang, I want better proof. When they pretend it needs no additional proof, I am flabergasted.
Last, I would like to thank you for providing this information, product of many readings and allot of thinking, to anyone who happens to pass by. I hope you find the time and willingness to reply this email, but if you don’t, I understand. Best wishes, Sergio Rossell
Sergio Rossell, 01:23 AM 8/28/2005: Hi, Thanks for your quick reply! SOME COMMENTS: [You wrote] "If you had only one gas expanding into a second empty chamber, maybe so. But I do not think heat or work must be supplied in order for the two gasses to mix." This is precisely the point. If gas A is distinguishable from B, it is expanding into an empty chamber (respect to gas A). The key is that A is different, and therefore, physically distinguishable from B. An example from standard physical chemistry books (cf. Physical Chemistry by Ira Levine, Fourth Edition ISBN 0-07-037528-3) is that of two chambers separated by an impermeable barrier and a membrane permeable to A but not to B (e.g. heated palladium is permeable to hydrogen but not to oxigen). Upon removal of the impermeable barrier, gas A will equilibrate between the two chambers but gas B wont. Supposing the chambers are of equal volume, pA in each chamber will be half the original (pA/2), but since B cannot cross the membrane pB will remain unchnanged in its own chamber and zero in the other. It follows after removing the barrier compartment I will have a presure of 0.5pA and chamber II 0.5pA + pB, therefore work or heat can be trasferred with the surrundings. If, however, gas A and B cannot be distinguished, then the delta S would not change. I will write down this example formally in a link inside (http://www.wichizaya.demon.nl/work.html), but mind that is not mine, it can be found in many standard text books on physical chemistry. I just begun constructing my web page, so there is not too much to see yet.
[You wrote] "Likewise, the opposing darwinian claim that organization can increase spontaneously, is unproven. This seems completely obvious to me. If darwinians say that their claim is proven by the big bang, I want better proof. When they pretend it needs no additional proof, I am flabergasted." I agree is not proven. I feel, as you do, that something is missing in the Darwinian position. But unlike you, I am not sure whether it requires extraterrestrial input. To my eyes it seems that we do not understand the relation between physics and biology suffciently well, and that is why we fail to explain the increase in complexity. I would consider the extraterrestrial hypothesis only after proof that indeed the terrestrial milieu is unable to sustain increasing complexty.
Brig Klyce, 12:56 PM 8/28/2005: The webpage you point to says, "The entropy associated with the expansion of a perfect gas is given by...." Why would this formula pertain to the mixing scenario, in which the volume, temperature and pressure do not change, and no work is supplied?
Sergio Rossell, 28 Aug 2005 14:15:52 -0500 (CDT): The mixing of two perfect gases requires them first to be separated in two different compartments, using similar notation as the webpage, before mixing the system's pressure P is: P1 = pA1 = pB1, after mixing, P2 = pA2 + pB2 and P1 = P2. So the system's pressure is unchanged. However, the partial pressures will have changed pA1 is different than pA2 and pB1 is different than pB1. You cannot mix gasses keeping their PARTIAL pressures unchanged and therefore there is an associated production of entropy. Partial pressures exist because the gases are PHYSICALLY DISTINGUISHABLE.
If you would imagine the two compartements filled by the same gas, no partial pressures would exist and, as expected, the entropy would remain unchanged after removing the barrier.
You can imagine a scenario were you do not allow exchange of heat nor work, still then, the internal energy of the system would change after mixing and entropy would increase. Mind that if you envision only Step 2 of the mixing (web site) and, in that way, maintain partial pressures unchanged; you would need to reduce the volume of the system with the same amount of work as the heat flux in Step 1.Hope it's clearer now.
Brig Klyce, 03:41 PM 8/28/2005: Sergio, it's not the least bit clear.
Sergio Rossell, 29 Aug 2005 02:47:13 -0500 (CDT): Hi Brig, Difficult thing we are trying to understand! but let's push further:
Partial pressure is not a physical phenomenon, it's a logical device.
This is not true, partial presures can be MEASURED (and have been) using semipermeable membranes.
But tell me this: when the two gasses mix, by how many joules per absolute degree does the entropy increase? Say there is a liter of oxygen and a liter of nitrogen, both at 20 degrees C, at one atmopshere? Open the valve. Pressure, temperature and volume do not change.
If you make the assumption that oxigen and nitrogen are are ideal gases and you mix 1 mol of each having them originally in separare chambers of the same volume, then the entropy production among mixing would be 11.52 J/K (using the equation in the web site).
If this were a cylinder of hot nitrogen and a cylinder of cold nitrogen, you could do the calculation without resort to little volume elements, so you shouldn't need them for the 2-gas problem either.
I have not used the little volume elements explicitely in any of my calculations. I think (but I'm not sure) that they are implicit in the partial presures and are infinitesimal (p=nRT/V), but I have no experience with logical entropy. If you have hot and cold nitrogen, there is a tempeture gradient that needs to be dissipated and will have an associated entropy production.
I would truly like to reach an understanding about this. Thanks. Brig
I am very glad to have had this correspondance with you. It is not an easy issue to discuss over email and you are right to doubt what I'm telling you. I think that if you would like to investigate this issue more in detail, a physical chemistry book would be best. Here you will find this problem addressed explicitely in terms of real examples (unlikely in a physics book). I plan to take looks at your web page from time to time and perhaps ask you some questions, is that is something you would like? Best wishes, Sergio
Brig Klyce, 10:07 AM 8/29/2005: Yes, I welcome your comments. I also plan to solicit comments on your entropy calculation from my other readers. Thank you!

Cosmic Genealogy: Emergent New Age Overshadowing The Big Bang, Darwinism and Intelligent Design
from Robert E. Cobb | Forelaws on Board | Mon, 22 Aug 2005 20:13:21 -0700 (PDT)
Dear Friends on Board: The Age of Cosmic Genealogy on Earth - overshadowing paradigms both ongoing and contending relative to origins while enhancing meaning and purpose - opens new vistas for contemporary science, philosophy and religion.
"Microbiology may be said to have had its beginnings in the nineteen-forties. A new world of the most astonishing complexity began then to be revealed. In retrospect I find it remarkable that microbiologists did not at once recognize that the world into which they had penetrated had of necessity to be of cosmic order. I suspect that the cosmic quality of microbiology will seem as obvious to future generations as the Sun being the centre of the solar system seems obvious to the present generation." (Sir Fred Hoyle, 1980, concluding a University lecture at the Sherman Theatre in Cardiff with the title "The Relation of Biology to Astronomy").
The Age of Cosmic Genealogy on Earth, having begun with human cognition of the oneness and interconnectedness of all life, appears destined to culminate with humankind as a conscious participant with all intelligent life in the infinite continuum of life.... www.geocities.com/forelawsship/CosmicGenealogy.htmlIn forelawsship, Robert E.

BACTERIA in July 4th Ejecta? | from Bill Parkyn

Dear Bryce ...I'm so addicted to keeping current to your 'What's New' that it already seems too long since the latest, 6 August. Anyway, please post some speculation on the idea that the talcum-like dust blown ouf of the July 4th comet was dried bacteria, as with Hoyle & Wickramasinghe. What was the reflectio spectrum of that stuff. I saw the 'new star' arise in my 18" Dob: barely 10 minutes after the impact time it was quite obvious.

Strong Evidence for Panspermia from Linguistics
from Joe Devin | Sat, 13 Aug 2005 01:27:21 -1000
Dear Sir, I am a researcher in computational linguistics living in Hawaii. Some years ago I published an observation on the Internet that ran something like this: As humans, it is clear that we have evolved physically in many directions. A Nordic European is very different from, say, an African pygmy. So it is clear that physical evolution of some kind is happening. But linguistically we have never evolved one iota from the moment humans first began to speak. Proof? Just take any infant from any culture in the world and raise that infant in any other culture in the world, and he/she will grow up to speak the local language just like any other local person. If language were evolving, this would clearly be impossible.
Perhaps a couple of years after I posted this observation, I heard a remark by some female narrator on an American science television program--perhaps Nova. She said, "Language is not evolving," but never mentioned where she discovered this information. Anyhow, where the panspermia idea is concerned, this discovery that human language has never evolved one iota from the time (some estimate 500,000 years ago) when humans first began to speak is of critical importance, because if language has not evolved at all in .5 million years, then there is slim probability that it ever evolved at all. It is quite possible therefore that some genetic upgrade floated in from space in the form of a virus arriving here .5 million years ago and infected people with the power of speech, and if so, then this is indeed strong evidence supporting the panspermia idea.
Personally, I strongly suspect that the panspermia model, or some panspermia model, is the right one for a few very powerful and very simple reasons, which I will express as follows:
1. My 19 years of linguistic research would indicate that the human linguistic apparatus is simply far too complex to have spontaneously evolved by any series of accidents. The naivete of such a belief rivals that of belief in beings like Athena, Apollo, the River Styx, etc.
2. All life and intelligence comes from other life and intelligence. The Darwinists have had access to all the best bio labs in the world for the past 150 years but have never once come even close to showing us how life might have sprung spontaneously from nonliving matter. They can't even duplicate this hypothetical process deliberately in their best labs, let alone by any accident ever known to man. A scientific hypothesis that will not submit to proof in this fashion is a scientific hypothesis that doesn't work, and according to the scientific method, deserves to be thrown out. Hanging on to untenable hypotheses is the work of high priests: not scientists.
3. All physicists I have ever heard of believe that either (1) the universe was once to hot for any life to exist or else, and equally damaging (2) that no life was possible before stars started to explode. Therefore all life in the universe had to come from some source outside the universe of that time.
4. That source of intelligence and life existing outside our universe is nothing more nor less than what we have always called God, the living source of all life as we know it.
So I do not BELIEVE in the existence of God, gods, or anything else, but I simply KNOW of the existence of an intelligent creator by means of these ironclad facts. --Joe Devin.
ID/CA | from Chip Morrison | 02:12 PM 8/2/2005
Brigger, Please explain, in simple terms, the difference between Intelligent Design and Cosmic Ancestry.... Thank you. Morrison...
from Brig Klyce to Chip Morrison | Wed, 03 Aug 2005 11:47:44 -0500: Dear Chip -- your timing is excellent, given George W. Bush's recent endorsement of ID....In brief, ID says that there must have been a miracle for life to originate, and other miracles for it to evolve from the simplest forms all the way to higher plants and animals.
CA agrees that these phenomena are not well accounted for by neodarwinism (ND).
But CA points out that the origin of life is not an observed phenomenon, only a firmly held belief. Firmly held by both ID and ND! The same is true of evolution, if you deconstruct it carefully. The evolutionary progress that takes life to higher forms is driven by the acquisition of new genetic programs for the features that higher forms have and lower forms lack. Both ID and ND attempt to account for the origins of these programs, ID by miracles, ND by science.
Many genetic programs are acquired by gene transfer. This fact already is a blow to ND, because in some cases the source species has no need or use for the program. If not, the ND account for its origin doesn't work.
But the origin of the programs is seldom even claimed to be observed. In 2000, W. Ford Doolittle even admitted, "Many eukaryotic genes ...seem to have come from nowhere."
Admittedly, programs can get *optimized* by ND processes. Optimization is also easily demonstrated in computer models. Not so for composing new programs for unforseeable, complex features.
So CA supposes that these things -- 1) life in the first place and 2) genetic programs for complex features -- never "originated." Maybe they always existed. If so, ID is right to assert that ND doesn't account for them. But ID is wrong to say that we must therefore resort to miracles. Interestingly, both sides agree that ID and ND are the only two choices, and both love the big bang, because it supports the dilemma.
CA contains no miracles, but it requires an amendment to the big bang theory. Life, even highly evolved, must have always existed. Having lived with this concept for years now, I find it no harder to accept than the existence of the universe. The existence of a physical universe is unexplained by science (even if it it began with a standard big bang.) Life is in the same category for me. Science doesn't explain it. But if it always existed, then there's no miracle in the finite past that needs explaining. Thus scientific faith is sustained.
These views are elaborated on the website, if you feel like poking around. Thanks for your interest. Comments invited....Brig Klyce | Astrobiology Research Trust
from Chip Morrison | 05:40 PM 8/3/2005: I need to find out more about Intelligent Design. Could not Nature be the intelligent designer? Is Nature too stupid for that? Not up to the task? I agree that Nature sometimes blunders. Does the Intelligent Designer also blunder? Or is that just Nature? Nature getting in the way?
from Brig: I know that ID requires miracles. Miracles cannot be investigated scientifically. So how ID works is not clear to me. Nature could only do it if Nature has a mind. ID is really just creationism made more palatable, they hope. (There are neodarwinists who think life is an inevitable result of properties of matter. That would be Nature I guess. But where's the evidence?)
from Chip: Also, you need to explain to me why it is necessary for CA that these genetic programs have always existed. From what I remember of the first paper of yours I read, a chief argument was that there hasn't been sufficient time for Nature to have developed the programs on Earth. If the programs come from afar, that solves the problem of time, assuming more time in other parts of the universe. But why does CA require that the programs always existed? Not enough time elsewhere?
Here I'm with the creationists. Suppose astronauts come upon a Chrysler Building standing on Venus. Venus hasn't existed long enough for a Chrysler Building to self-assemble by chance. But if you had forever? In forever anything can happen, right? Sorry, I'm not buying it. Even forever isn't long enough.(An interesting sidetrack: Mars has existed long enough too have a grand canyon whose exact specifications are probably as detailed as those of the Chrysler Building. How is the Chrysler Building different? Creationist William Dembski writes about this. "Complex Specified Information".)
That argument works for "the origin of life." For evolution to ever higher forms after that, I think there's a second-law-of-thermodynamics equivalent that prevents it. True, now the number of possibilities can be counted. But the number for a single gene is like 4^1000 or about 10^600. (Try http://www.panspermia.org/proof5.htm)
Also, I need to be clear. You agree that life forms have evolved on Earth, but with a sort of assist from external sources. Universe is teeming with life, Earth is open system, life forms from afar mingle with life forms here, producing forms that could not have evolved using only local material. Is this correct?
Yes. Although once the material arrives, then it's local. And it could arrive long before it's deployed.
BTW, I don't see that gene transfer is blow to ND, just because programs are not always useful. Should be okay, as long as not harmful?
How did the gene acquire the program it needs in the recipient species, when, sometimes, there was no selective pressure to write the program in the donor species? Another unanswered question for ND....

An infinite universe | from Mark Mukai-Warner | Tue, 2 Aug 2005 11:33:38 EDT
Dear Mr. Klyce, I am a suststainable development design consultant and teacher who is currently working on a series of science fiction novels. In my research for the novels I came accross your discussion on the 'META' site and found it most interesting.
I must say that I fully appreciate how difficult it is to present an idea that is so contrary to most peoples' fundamental world view, and how vehement can be their antagonistic reactions. I am truely grateful for people like yourself who refuse to give in.
I grew up with the impression (as I'm sure most people do) that the Big Bang theory was fact, but it never 'felt' right to me. Discovering the Steady State theory was a revalation. Upon further research and reflection I came to understand how deeply rooted the creationist paradigm is in the western (and unfortunately increasingly global) psyche. When I was a kid I remember being told that if people try to think about infinity too much they could go mad. I've thought about it a lot - it is to my mind very comprehendable; either that, or I have gone mad!
To me (as an interested lay-person), the BB theory is synonymous with creationism. The SS theory 'feels' right (very unscientific of me, I know, but science is just a toolbox, one of many).
My point is that I happily go along with your 'Cosmic Ancestry' idea. I know you don't subscribe (publicly) to any particular cosmological theory, but you do propose that life has no particular 'origin', which suggests time without beginning and that equates to my understanding of the SS theory.
I am a practicing Buddhist (I hope to get it right, one day) and one of the reasons I was attracted to Buddhism (along with there being no god or rules) was its cosmology. Buddhist texts describe the universe as eternal, infinite, unbounded and describing cosmic cycles. Buddhist philosophy is one of life, the very nature of reality, and embraces all other religions, science, and philosophies within the Mystic Law. Put very simplisticly, the Mystic Law states that there is infinite potential for and temporary manifestation of all phenomena. Phenomena arise through cause and effect. Phenomena exist, or they don't exist - the ultimate reality is neither existence nor nonexistence, but exhibits the qualities of both.
I'd like to recommend an excellent book, a dialogue between Chandra Wickramasinghe and Daisaku Ikeda, called 'Space and Eternal Life' (Journeyman Press, 1998, ISBN 1 851720 60) which I believe you may find of interest. [Another look at your website shows me an essay by Mr. Wickramasinghe and yourself, you may already be aware of the aforementioned book].
My reason for writing to you is to make contact, say thank you, offer moral support and, maybe, engage in dialogue. As I stated above, I am writing a series of SF novels. It is my wish to tell a story of human integration into galactic society, set within an infinite and eternal universe. 'Panspermia' is the the way life spreads and is, at the material level, what unites all sentient species. I would be interested in having some professional opinion and constructive criticism on how I deal with these issues. In return, I would like to do what I can to bring such issues further into the public domain through the medium of literature.
With my deep respect, Mark Mukai-Warner

Evo-devo | from Stan Franklin | 09:02 AM 7/25/2005
Brig, Does evolutionary developmental biology (http://www.answers.com/topic/evolutionary-developmental-biology) speak at all to your quest for genetic novelty. They’re concerned with morphological novelty. Would that constitute a genetic jump in your sense? Or, an explanation for the lack of such jumps? ...Stan
Stan Franklin | Computer Science | The University of Memphis
From Brig Klyce | 10:14 AM 7/25/2005: Dear Stan -- Thanks for keeping this question in mind. Yes, I think that changed morphologies and increased or decreased numbers of body segments can be achieved without new genetic programs, with things like regulatory changes instead. These might come from point mutations, gene duplications, or maybe even no sequence changes at all (Could cytoplasmic chemistry changes in response to environmental factors have regulatory effects on development?)
But I think it is obvious that new genetic programs are needed for almost any new evolutionary feature (photosynthesis, eyes, etc.). Evo-devo does not even suggest, to my knowledge, how these could be written.... Brig Klyce | Astrobiology Research Trust

Right Questions, Wrong Answers. | from Gabriel Manzotti
Fri, 1 Jul 2005 12:46:47 +0200 (CEST)
Dear Brig, The last "Reply" suggests that there are indeed "Right answers" in Cosmology and Fred Hoyle in these field put the right questions but gave the "Wrong answers". So far so good! Please let me check the lesson. According to the Scientific Community the "Right answers" are that we certainly live in a Big Bang Universe which bootstrapped in a some acausal way 13.7 +/- 1% Gyr ago, begin to expand being filled with radiation, ordinary matter, dark unconventional untested non baryonic matter, dark unconventional untested energy. All of these different contributions vary in time, in a way that leaves their sum equal to the closure density parameter of 1, which is the outcome of a never observable inflation phase. The last two entities, "dark" matter/energy, now represent 96% (Ninety-six %) of the global content of the universe. In this scenario, a unique, single, generation of galaxies evolved in a "bottom-up" way from "primordial fluctuations" superimposed to an overall smooth and homogeneous background expansion which at first decelerates then accelerates. In spite of the lack of definition in the initial conditions, the theory supply us with a remarkably precise time of evolution as the age of the universe is no longer an order of magnitude estimate, but is a true measurement ( +/- 1% according to WMAP satellite results) in compliance with the claimed turn to the "Precision Cosmology Age" (Peebles 2003).
Had you the impression that this set of involved assumptions are purposely aimed to sustain a cozy "World System" instead of reflecting reality, please remind that once they are dressed under the scientific politically correct form of a respectable seven (at least seven) parameters, falsifiable (?!?) theory, they lead to the "Right Answer" and Fred Hoyle who raised for a lifetime doubts against this apparently humongous straining of reality, was wrong!

Guardian Unlimited: Right questions, wrong answers
from Jeff Nesin | Thu, 16 Jun 2005 13:06:55 +0000 (UTC)
...as two books trumpet Fred Hoyle's legacy, Tim Radford assesses a visionary scientist who went too far —
Fred Hoyle was the man who worked out just how stars in a galaxy far away and long ago forged the carbon, oxygen, iron, silicon and other elements that became the molecules that became the organisms that ultimately turned into astronomers and accountants, authors and automatons. Fred Hoyle was also a wartime backroom radar scientist, a successful science fiction novelist, a colossal academic fighter and - in later life - a grade one batty boffin who argued that diseases were forged in space and delivered to Earth by comets and that the archaeopteryx specimen in London's Natural History Museum was a fake.
Fred Hoyle coined the phrase "the big bang" but intended it dismissively, clinging stubbornly to his belief that the universe had always been there. Colleagues often dismissed him as eccentric, but they also described him as "a towering figure", and brilliant.
Brilliant? His seven-part television series, A For Andromeda, launched Julie Christie in 1961. By the end of the sixth episode, 25% per cent of the UK population aged five and over were watching it. But he also clashed with another giant of astrophysics, Martin Ryle, and got the worst of a sometimes bitter argument. In the end, Hoyle fell into eclipse, and died in 2001. Then, after a four-year wait, two books have come along at once. The man mattered. He may have had the wrong answers, but he asked the right questions: what is this universe, and where did life come from?
Simon Mitton, an astronomer, a sometime student of Hoyle and himself a publisher, is the author of Fred Hoyle: A Life in Science (Aurum Press). He sees his subject as the outgoing, far-seeing figure who put British cosmology on the map, if only because he could see across the Atlantic. "He gave British astronomers, in the 1950s and early 1960s, [the impetus] to look to the US as a source of rich collaboration rather than a place of envious competition," says Mitton.
"People like Martin Ryle ... always regarded the US astronomical community basically as devils incarnate. It was Hoyle who said we have got to take these people seriously. Then in the late 1960s and 1970s he started the programme at the Institute of Theoretical Astronomy, inviting distinguished Americans to come over and interact with British graduate students. He got the funding to pay their air fares ... and salaries. He absolutely refounded theoretical astronomy in this country."
"When you bear in mind that at the present time a quarter of all the papers published by the Royal Astronomical Society are in cosmology, the theoretical cosmology output of this country is absolutely staggering," he adds. "Theory is the thing the Brits should try to be good at, because all the telescopes are overseas, and you only need a pencil and paper to do theory." People like Stephen Hawking went to Cambridge to do cosmology simply because Fred Hoyle was there. Martin Rees, astronomer royal, president elect of the Royal Society and master of Trinity College, began post-doctoral research in Hoyle's institute and has always felt warmly towards him.
Jane Gregory, author of Fred Hoyle's Universe (OUP), meanwhile, first talked to Hoyle in 1993 because she had begun a PhD on popularisation of science. "It was supposed to be on popularisation but I got kind of stuck with him because he was a great case study: he had a 50-year career and he had done the astronomy stuff, the biology stuff and the fiction," she says. "He ended up being a means by which I could look at different kinds of popularisation."
Gregory has her own theory for the fading of one of Britain's brightest luminaries. Hoyle never liked to let go of an idea until he had wrung everything from it. The ideas about life in space had been with Hoyle since the 1930s.
"So it's not something that came on him when he was going a bit batty in old age," she says. "It was something he'd been thinking about for 50 years by the time it got famous. If you've been working on an idea for 50 years, you don't walk away from it because your mates say it's a bit silly."
Martin Rees thinks that Hoyle espoused the idea that life began in space - the idea is known as panspermia, and it's a century old - because he liked the idea of a "steady state" universe that had always existed. The origin of life on Earth, and so far, only Earth, is one of the science's great unsolved riddles. Hoyle famously described the standard evolutionary explanation involving primordial soup and a warm little pond 3bn years ago as being as improbable as the assembly of a jet airliner during a hurricane in a junkyard. "With an infinite past, you could relegate the origin of life infinitely and forget about it," says Sir Martin. "I think the motivation for panspermia vanished once we had the big bang theory because the age of the universe then becomes only two or three times the age of the Earth. Fred is better known to the public for his advocacy of the steady state theory and his later eccentricities but his greatest lasting contribution is his pioneering work on the understanding of origin of the chemical elements, and how all the carbon, oxygen and iron that we are made of were synthesised in stars from pristine hydrogen. And that's his great achievement, I would say."

Information Theory, Evolution and the Origin of Life
to Hubert P. Yockey from Brig Klyce | 6:15 PM 5/17/2005
Dear Dr. Yockey -- I was very pleased to receive an advance copy of your new book. I read it carefully and posted a review on my website.... I especially noted your sentence: "Once life has appeared,... genetic messages will not fade away and can indeed survive for 3.85 billion years without assistance from an Intelligent Designer" (p 181, 184).
In my review I expressed disappointment that you didn't say much more about evolution: Where do new genetic programs come from, according to Information Theory? Now I wonder. Perhaps you think, as I do, that the genetic programs for all of higher life must already exist, in essence, from the beginning. You do not explicitly say so, but the quoted sentence implies it. Your comments are welcome.... Thank you.... Best regards. Brig
Reply to your e-mail of 5/17.2005 | from Hubert P. Yockey | Thu, 19 May 2005 10:35:01 EDT: Dear Dr. Klyce: How nice to receive your e-mail and your review of my book! ...I thought I gave the creationist/intelligent design folks, el momento de la verdad! I am more than skeptical about their essentially religious views. I started the book with the reference to Socrates to emphases that science is founded on measurement and mathematics not on faith. I criticized frequently scientists who based their conclusions on faith. As you know the founding fathers believed in the separation of church and state, First Amendment U S constitution: Congress shall make no law respecting the establishment of religion or restricting the free exercise thereof....
With regard to what is knowable please note the quotation of Niels Bohr on page 5. See also Chapter 11, Randomness, complexity, the unknowable and the impossible. These subjects are not understood by many scientists. They are often refereed to as "buzz words".
Michael Behe, who poses as a scientist, has done an enormous amount of damage. The argument in my book is based on publications by Gregory Chaitin, especially "Irreducible Complexity in Pure Mathematics". You may find this paper and download it from his home page. My theme in the book is that genetics works like a computer. Since the genome is read out to direct the formation of protein, the genetic message cannot be "irreducibly complex". Chaitin shows which sequences are "irreducibly complex" and those that are not. Of course this is far above Behe's head and of his creationist/intelligent design folks. You might find it useful to discuss my reasons why genetics is not "irreducibly complex" with one of your mathematicians. I suggest you go to Chaitin's web page and print out some of his papers on complexity and irreducibility. Try these ideas on your friends! The origin of life, like the origin of the universe, is unknowable. If life were just complicated chemistry, as Jeffrey L. Bada teaches his students, proteins would be composed of amino acids of both handedness.
I discussed the question of how new genetic programs come de novo in my book, Information Theory in Molecular Biology published by CUP in 1992, see Section 12.3. Perhaps your inter library loan can find this book. I wrote it as a textbook and the mathematics scarred off most people. One must decide what can be put in one's book. Being too encyclopedic makes the book so large and expensive that very few will be sold.
A unique characteristic of mathematics is that once a theorem is proved that ends the debate. One may debate the pros and cons of income tax policy but not the theorem of Pythagoras!

Hello Brig ...I just wanted to say that I am thoroughly enjoying your website and all the associated links. I am an artist from NJ, USA and I have recently started producing some art that has been inspired by various readings in science. I have attached a picture of a sculpture I just completed. It consists of an apple that has been "unzipped" to reveal a flurry of pollen-like structures that are about to be disseminated. It is entitled "Panspermic Apple". The picture is a bit blurry, my apologies, but hopefully it captures the essence of this interesting theory.
thanks, and keep up the good work! ...Paul Grech | www.pngconcepts.com
PS, 29 April: I am a huge proponent of the sciences, and am trying to fuse art with science in the hopes to encourage deeper thought among the various people with whom I come in contact.
Re: functional tRNAs from separate genes | from Dieter Söll

Dear Brig, Sorry for the late reply - I was away for three weeks. Your article is concise and correct. An evolutionary question in this case (as in others) is whether this small genome is a consequence of genome reduction or of an early stage in building a larger one. If it was the former model, then one could imagine that the intact tRNA genes got split during the reduction stage. Unfortunately, there is no function of the tRNA that could be carried out by the half molecules; thus, it is difficult to argue that the half molecules could carry out partial reactions of the current function of a tRNA. Best regards, Dieter

[The 6th item in the list is about the Labeled Release (LR) experiments on Mars: "JULY 20, 1976. On Mars, the Viking landers have scooped up some soil and mixed it with carbon-14-labelled nutrients. The mission's scientists have all agreed that if Levin's instruments on board the landers detect emissions of carbon-14-containing methane from the soil, then there must be life on Mars. Viking reports a positive result. Something is ingesting the nutrients, metabolising them, and then belching out gas laced with carbon-14."]

The Ascent of Humanity | 10:27 PM, 17 Feb 2005 | from Charles Eisenstein
Dear Brig, We corresponded a while back about my upcoming book, The Ascent of Humanity. The bulk of the text is now finished and I'm halfway through the second draft, which I'm putting up on line as I complete each chapter. There is much in the book that is relevant to your site, as is not surprising given the number of valuable resources it pointed me toward. Anyway, my website (www.ascentofhumanity.com) links to panspermia.org, and I also mention you in the short essay I just posted there, entitled "Darwinism vs. Creationism: A Superficial Disagreement", which you might enjoy. Take care, and thanks for your valuable work.

Complex early genes | to Dr. Scott Roy from Brig Klyce | 11:17 AM, Thu, 3 Feb 2005
Dear Dr. Roy -- I have read your subject paper with keen interest. I have a comment and a question. Comment: The word "origin" is often used without positive evidence. "Earliest known example" is usually all that's warranted. Question: Your cited evidence and references do not seem to justify your dismissal of "parallel insertion." (Also called "homing," I believe.) Do you have other reasons not stated in the paper?
The same comment and question are posted with my discussion of the article on my website about panspermia at http//www.panspermia.org/whatsne36.htm#050203. I would be honored by any reply from you.... Thank you and congratulations for the article. Best regards. ...Brig Klyce / Astrobiology Research Trust....
At 12:44 PM 2/3/2005, Dr. Scott Roy wrote: Dear Brig, In most or all cases, I use "origin" in the context of "these results push back the origin...to early eukaryotes." Whether or not the origin of complex genes goes back further is beyond the power of this data to resolve and likely unknowable (if, as seems likely, eukaryotes thought to be deeply diverging have lost nearly all of their introns, a notion supported by Collins and Penny's recent finding of a complex spliceosome in the common eukaryotic ancestor (MBE, 1/05). Both Wally and I have been long-time supporters of the notion that introns are extremely old, and we are not here trying to pinpoint their origin at the beginning of eukaryotes, only to say that, regardless of their ultimate origin, there were already a lot of them by early eukaryotic evolution.
I do have more direct evidence that the data cannot be explained by parallel insertion. In short 1) there are too many occurrences of protosplice sites in the studied regions to explain the two-way correspondences between deeply diverged species; 2) there are too many three-way correspondences between deeply diverged species; 3) numbers of introns shared between species varies widely between genes, as expected if different genes have different rates of intron evolution or if introns are lost in concert (e.g., Roy and Gilbert, "The pattern of intron loss", PNAS 1/05); 4) introns present in multiple outgroup species and a sister are not particularly more likely to be retained in a species than are those found in only a sister and single outgroup. This last one takes some more explaining, but I will leave that for a manuscipt currently in preparation.
You have misinterpreted our table. You say "the number of modern introns present in various ancestor species appears to increase as one looks deeper into the past, as the above table shows. (Going right, the numbers increase.)" This is twice wrong. First, species to the right are more recent, not more ancient. Secondly, this table is not talking about intron number in ancestral species, but the fraction of introns in modern species which were already present in the genomes of various ancestors. Estimated numbers of introns are given in the color figures.... Thanks for your interest. Best, Scott

Craig Venter endorses panspermia | 0137 PM 1/21/2005
from MCKAY, DAVID S. (DAVE) (JSC-SA13) (NASA)
Brig, this is an important statement by Venter, and reinforces my own views that life travels around as microbes. The radiation effects are still a problem. These effects (DNA damage mainly) make it difficult or impossible for individual microbes to surive in space. That is why I am skeptical of the data from the India balloon flights. I think the Mars meteorite data (we are still absolutely convinced we are right about ALH84001, Nakhla, and some others--more papers will follow this year) suggest that the best and perhaps only way for microbes to travel around in space is within a radiation shielding system provided by rocks. The size of the rock determines the degree of shielding, and very large rocks such as whole asteroid masses may be possible for inter solar system travel.
I was not aware of the Edge.org site. It is very nice. I have put your site on my favorites list and will check it periodically. Feel free to alert me by email of new and exciting things. ...Dave
PS: These
views represent only my own and I am not speaking as a NASA representative.
0137 PM 1/21/2005 | from Brig Klyce: Dear Dave -- I am very encouraged by your email. Thank you! As for the balloon-recovered microbes -- if comets carry them most of the way (especially if some comets are small enough to go undetected), maybe they weren't exposed for very long, so they might have a greater-than-zero survival rate. Also, even if we found ET isotope ratios in radiation-killed bacteria only, that would still be interesting, wouldn't it?My son's AP Biology class recently invited me to tell them about panspermia. I proudly told them that I was acquainted with the guy who found the fossils in ALH84001. [...] I will watch for your future papers. Thanks again. Best regards. Brig
