The few really big steps in evolution clearly required the acquisition of new information.... — François Jacob, 1982

Replies to Cosmic Ancestry, 2009

5:57 PM: Dear All, Here are links to the updated NASA JSC web site on new evidence for life on Mars. This site contains new information not in the November release and these sites are worth looking at: [main press release]

The release includes the complete text of the just-published Geochemica paper which is mostly about the ALH84001 magnetite. The alternate hypothesis that this magnetite was made completely non-biologically has been the leading competing explanation for our biologic hypothesis for about 10 years now. We believe that this paper completely falsifies this alternative hypothesis. The Powerpoint presentation (converted to PDF) on the press release site explains this a bit more simply than the paper itself. The importance of this paper cannot be underestimated; this non-biological alternative hypothesis has been the main obstacle in the scientific community to our original hypothesis that the magnetites were made biologically, and until it could be falsified, our hypothesis could not gain widespread acceptance. This new paper shows unequivocally that the proposed hypotheses (thermal or shock decomposition of siderite (iron-rich carbonate)) simply will not work and will not produce most of the magnetites actually present in the meteorite. These data are indisputable. If this alternative hypothesis does not work, we are left with our original biologic hypothesis for the specific kinds of magnetite which are identical to those made by bacteria on earth. [educational presentation: 59 charts] (slow loading)

At this site (part of the press release site) is a powerpoint (converted to PDF) presentation showing the status of the martian meteorite study, the status of Mars exploration, and plans for the future. This presentation has already been picked up by a number of teachers for use in their classrooms. Take the time to download it and run through it. Be sure and allow enough time for the animations at several charts to load and run (you may have to click on them) The animations include the carbonate pancake cartoon and the revolving magnetite crystals. [abstract, doi:10.1117/12.832317, vol. 7441, SPIE Proceedings, 11 Sep 2009.]

The second paper just published (SPIE Proceedings) discusses the status of our ALH84001 meteorite studies, shows some new data on biomorphs in this meteorite, and shows a number of Scanning Electron Microscope images of biomorphs (potential martian microfossils) in two other martian meteorites, Nakhla which fell in Egypt in 1911 and Yamato 000593 which fell earlier in Antarctica and was recovered by the Japanese Polar Expedition a few years ago. The biomorphs in these last two meteorites are nearly identical, supporting our hypothesis that they formed on Mars; it is unlikely that microbes grown and fossilized in Antarctica would be identical to microbes grown and fossilized on a Nile delta field (or in the British museum where Nakhla has spent most of its terrestrial life). We see considerable carbon in Nakhla much of it associated with these biomorphs; Tim Jull of U of Arizona has shown that at least ~70% of the carbon in Nakhla is not terrestrial and therefore came from its original location (positively identified as Mars. Most biologists that I have shown these pictures to agree that they are likely microbial remains and fossils. [directory and new images]

This last feature consists of 20 SEM images of biomorphs in Nakhla and Yamato (on two pages), most of them previously unreleased and unpublished. These show a selection (from hundreds more) of the kinds biomorphs that we have found. We have found similar features in nearly all chips of Nakhla and Yamato 593 that we have investigated, and we think it very unlikely that these are contaminants from earth.

While we do not yet claim that we have rigorously proved that there is life on Mars, we believe that we are very close. In 2010 we plan to perform ion microprobe on a number of these biomorphs to try to determine unequivocally whether they were formed on Mars (textural or stratigraphic releationships already support that interpretation), and to unequivocally determine if they were made biologically rather than non-biologically (based on carbon isotope ratios and the presence of minor bio-elements such as nitrogen), although their complex texture and morphology certainly supports a biologic origin. If even a few of these features is shown by detailed chemistry to be martian in origin and is shown to be biologically produced, the presence of microbial past and possibly currently life on Mars becomes a near certainty.

7:55 PM: Hi, I just want to say I concur with your analysis on the discovery of 3 human-specific genes that were purportedly recruited from ncDNA. It seems more logical to presume that a previously disabled gene in primates (due to a frameshift) had been reactivated in the human lineage for reasons that are still unclear. Could it be useful for mitigating the effect of lymphocytic leukemia?

Also, isn't it the case that the equivalent stretch of DNA in chimps is still coding, albeit for a shorter protein or has it lost its regulatory features entirely? That part is not clear in the paper by McLysaught. Regards, JH.

15 Dec / 10:07 AM: Dear Joe -- Thanks for the comments. I do not know the answers to your first question. For the second one, I think the paper would have mentioned it, if the chimp sequence is translated. But dunno. Perhaps another respondent will weigh in? Thanks again. Best regards. Brig

4:19 PM: Brig Klyce, Thanks for providing our paper in your references on CNGs. I'm interested in your take on our recent paper and how it relates to your thesis on panspermia. Although, I have a comment on this:

In cosmic ancestry, the CNGs themselves would have been horizontally acquired as well. The new data even seem to support that alternative according to criteria we stated in April 2002: "If a new genetic program arrives by the strong panspermia process, intervening species should possess either nearly identical versions of it... or nothing similar..." (4). These CNG's are even more nearly identical, among species from mice to humans, than we would have guessed.

I'm sure you realize that CNGs can be present for another reason (besides recent exogenous transfer) and that is of course - strong selection. The determination of the functions of ncRNAs is currently a particularly active area of research. Those newly discovered functions will likely provide a mechanism by which the necessity for strong selective pressure is explained. Coding regions are less weakly conserved because proteins do not need to be highly conserved to preserve function, i.e. they are mutationally robust in most cases - with the exception of a select number of catalytic residues. The functionally of CNGs may be less robust to mutation - which would necessitate strong conservation. The conservation alone does not sufficiently prove they are exogenic. In fact, unless acquired very recently or under strong selection, an exogenous sequence will appear to have experienced similar levels of drift as native sequence.

Gregory E. Sims, PhD | Computational Scientist | Lawrence Berkeley National Lab

22 Oct 2009 / 1:05 PM: Dear Dr. Sims -- Thank you for noticing. I am aware that strong selection can keep sequences constrained very tightly. But this leaves a problem for standard darwinian evolution -- how did the sequence "originate"? If by mutation and natural selection, then there must have been a time when they weren't so tightly constrained. But this supposition is not supported by evidence, as far as I know. Are there sequences that would support the darwinian account of gradual evolution of these CNGs?

In general, the version of panspermia that I promote is so radical that it is hard to grasp immediately. (It was for me, too.) In it, every genetic program must be supplied. Darwinian evolution can only shuffle, toggle and optimize supplied programs. So in "strong panspermia," every genetic program was ultimately supplied by some form of HGT, whether recently or eons ago.

The direct evidence for HGT as the source for genetic programs is accumulating steadily. But the main reason to consider this hypothesis is that the direct evidence for darwinian mutation-and-natural-selection as the source for genetic programs is so weak and indirect. Without the big bang as its foundation (everything must originate), it would be laughable, in my opinion.

I welcome your thoughts, as long as good will prevails! Thank you. Best regards. Brig

Exotic life beyond Earth? Looking for life as we don't know it,, 18 Sep 2009.

11:58 AM: Dear Brig I donít think that the number of believers really matters; I mean if we give to the extraordinary claim a more ordinary and less fascinating form, something like "From nasty primordial soup to marvellous Carl Friederich Gauss, simply shake some billion of billion of billion of atoms and roll the dice, Earth based random game fully guaranteed against repeated extinctions in six hundred million years, satisfied or full refunded wholesale " well I think not even 20 billion believers could convince me to accept it! What really matters in my opinion is the complete lack of a rationale: of course I consider the appeal to "blind natural forces" equivalent to the complete lack of a rationale, something like to "Oh well, we do not have the faintest idea about how it works, but we love it very very much". Reductionists, good fellows! ...Ciao Gabriel

2:14 PM: Gabriel, I am with you. The only virtue of my proposed criterion, "if most people don't believe it," is that it is quantifiable. Thanks for the feedback. Best regards. Brig

Primate-specific genes were inserted de novo... is the related What'sNEW article, 23 Jul 2009.

4:30 PM: Dear Brig, Thank you for posting a summary of our work on your website. I have a few comments:
+ the newly acquired retro-genes are not lost progressively during development but are lost after birth, progressively during adult life. These sequences can be in fact detected by PCR amplification, sometime also by Southern blot analysis, in tissues from young animals but are progressively lost in tissues from aged animals. This is shown in figure 3 which reports the comparative anlysis of DNA samples extracted from tail tissues of 20, 40 and 60 days old mice.
+ although maintained as non-integrated extrachromosomal structures, these retro-genes can indeed be sexually transmitted from one generation to the next because they are stored in spermatozoa. Therefore the corresponding phenotypic traits are also inherited by the progeny, although paradoxically in the absence of specific(s) chromosome-linked gene(s).
+ I am convinced that SMRGT process has played a role in evolution. Reverse transcriptase is encoded by retroltransposons which are stress-responsive elements, including among others exposure to UV, ionizing radiation, toxic agents and starvation. On these grounds it is reasonable to hypothesize that exposure to drastic environmental variations may have promoted bursts of newly synthesized retro-genes with ensuing sudden consequences on macroevolution.

Best, Corrado | L'Istituto Superiore di Sanità (ISS)...

6:27 PM: Corrado, thank you for these clarifications. ...With respect to heritability, I have been totally focussed on evolution that becomes permanent. Could the non-integrated extrachromosomal structures, the retro-genes, be thought of like bacterial plasmids -- permanent parts of the heritable genome in those species? Or, could they become integrated later, over longer times than you can experimentally observe? Thanks again for your help, and for your original work! Best regards.
6:37 PM: ...I have amended my text. I hope it's OK now. Still curious about my questions. Thanks. Brig
8:57 PM: One more question: you wrote --

although maintained as non-integrated extrachromosomal structures, these retro-genes can indeed be sexually transmitted from one generation to the next because they are stored in spermatozoa. Therefore the corresponding phenotypic traits are also inherited by the progeny, although paradoxically in the absence of specific(s) chromosome-linked gene(s).

I have now re-read your paper with that isue in mind. You say that the sperm of the F0 generation take up the DNA or RNA and that sequence is expressed in the F1 generation. Also the sperm of the F1 generation contain the acquired DNA or RNA. But did F1's sperm acquire it from the environment, as with F0? Or did F1's sperm inherit it from the parent, like a sex linked chromosome? In the latter case, isn't the inheritance now mendelian? Thanks. Brig

26 Jul / 7:33 AM: I'll try to answer to your questions:
+ I agree with your view that reverse transcriptase-generated extrachromosomal retro-genes can with time get integrated in genomic DNA and then fixed in the germ line. My guess is that such integrations occur mostly in the very early stages of embryonic developmant, 2- 4-cell stage embryos.
+ Spermatozoa are extremely reactive cells able to take up both DNA or RNA molecules and to deliver them to oocytes at fertilization. This is a distinctive feature of sprmtozoa of virtually all animal species, including human.
+ Reverse transcriptase-dependent retrogenes are sexually transmitted as extrachromosomal structures through spermtozoa from on generation to the next. It is not yet clear if oocytes do the same. Inheritance of non integrated sequences is quite unpredictable: we have observed a mosaic distribution, in the sense that they are present in some embryonic territories but not in others and therefore some organs of adult animals will be transformed while others will not. In ddition, these retro sequences are transient in adult tisues, are abundant in young nimals while their amount declines with age.

Best, Corrado

Replies from Darwinists

We sent out email alerts about our recent What'sNEW article, Primate-specific genes were inserted de novo..., posted 23 Jul 2009, because we thought it was especially important. Most of the feedback we received was positive and gratifying. We hoped that the negative feedback would be illuminating, but we have been disappointed. Darwinists seem unwilling to look closely at the evidence. In this shaded box are two examples with our responses, all edited down to the essentials.

from a nationally known government expert on evolution

25 Jul 25 / 11:24 AM: ...One of the mechanisms they propose in the discussion is retrotransposition since most of the genes have only one exon.... In other words, there are simple hypotheses for actual molecular mechanisms.

2:49 PM: If a primate-specific TU, even if only one exon and of only average length 1) serves a primate-specific purpose, and 2) has no non-primate precursors, then how did it acquire its programming?

3:04 PM: Natural selection.

4:04 PM: If it was natural selection, there would be evidence of gradual divergence, wouldn't there?

[No answer yet]

from a blogger who campaigns against creationism/ID

27 Jul / 10:48 AM: ...At an early time, some 70-60 million years ago, the "primate niche" was still available, and the organism that got some genes inserted into its DNA during reproduction managed to survive, and its descendants radiated into what is today known as "primates". This is quite simple, and standard (mainstream) knowledge in biology.

5:03 PM: The main point is that if these 131 primate-specific genes have primate-specific functions, and if they have no non-primate precursors, then there was no opportunity for darwinian mutation-and-natural-selection to compose them. So how they got written is unexplained in darwinism.

6:06 PM: ...But over the course of tens of millions of years, a jackpot is almost guaranteed. And gene insertion (a normal evolutionary mechanism) is one of the standard ways to "hit the jackpot"....

28 Jul / 10:13 AM: Your math doesn't work here. The average TU in the study I mentioned was 1500 nucleotides. Even if 90% of them can vary without restriction, 150 nucleotides must be correct and in order. The chance of getting this right in one trial is 4^-150, or about 10^-90. So tens of millions of years is not long enough. Not even close.

29 Jul / 1:55 AM: ...In the course of a few tens of thousand years the genes mutate due to environmental pressure (adaptation to the niche), and take their present-day form, at which point you identify them as "primate specific" genes. Yes, they are now, but they weren't back when they were inserted.

10:43 AM: The point of the original report is that they already were primate-specific, without recognizable precursors. Maybe after insertion they did mutate as you describe, but the range of this process would be narrow, only optimizing what was already there. Such optimization is well-observed and can be demonstrated with computer models. Making new sense out of lengthy random sequences has not been demonstrated in any medium.

...Gene regulators may bind promiscuously, but they often do nothing by Lynn Yarris, Science@BerkeleyLab, 15 Feb 2008.

8:37 AM: Hi Brig... May be that some of the following links could be of your interest for your "the end and the big bang" webpage. The first (Narlikar's) paper, frames the present Standard cosmology in the right historical context and highlights its success and shortcomings. The second (Disney's) casts motivated doubts on the actual "Scientific" status of Cosmology. The last (Lopez-Corredoira's) suggests that the success of the present Standard Cosmological model, beyond its technical motivations, could someway rest also on the Mainstream (and Sidestream) Cosmologists social behaviour. Here Below a short and someway funny excerpt of this last paper.

"(..) 2.3. Psychological profile of cosmologists -- There are two main psychological profiles of cosmologists, with gradations of grey between them:

Heterodox: Possessed by the complex of unappreciated genius, too much "ego", normally working alone/individually or in very small groups, creative, intelligent, non-conformist. His/her (mostly males) dream is to create a new paradigm in science which completely changes our view of the Universe. Many of them try to demonstrate that Einstein was wrong, maybe because he is the symbol of genius and defeating his theory would mean that they are geniuses above Einstein. Most of them are crackpots.

Orthodox: Dominated by the groupthink, following a leader's opinion as in the "Naked king" tale, good workers performing monotonous tasks without ideas in large groups, specialists in a small field which they know very well, conformist, domestic. His/her dream is getting a permanent position at an university or research center, to be leader of a project, to do astropolitics (see Lopez-Corredoira 2008). Most of them are like sheep (or geese3), some of them with vocation of shepherds too.

The sociological reasons for favouring orthodox proposals might be related to the preference of domesticity in our civilization. Sheep rather than crackpots are preferred. Finding a promising change of paradigm closer to the truth among thousands of crazy proposals is very difficult; in orthodoxy, although absolute truth is not guaranteed, at least a consensus version of the truth is offered."

Einstein and cosmology by J.Narlikar -- Abstract: This review gives a historical account of how cosmology has developed since the 1917 paper of Albert Einstein. Today it is a frontier level science drawing on contemporary astronomy as well as contemporary physics, stretching both as far as extrapolations will permit. Thanks to numerous observations at different wavelengths, cosmologists today have their plates full. Extrapolations of laboratory tested physics are called for to understand all information within the framework of a standard model. The success and shortcomings of this approach are briefly discussed against the historical backdrop.
The Case Against Cosmology by M. J. Disney -- Abstract: It is argued that some of the recent claims for cosmology are grossly overblown. Cosmology rests on a very small database: it suffers from many fundamental difficulties as a science (if it is a science at all) whilst observations of distant phenomena are difficult to make and harder to interpret. It is suggested that cosmological inferences should be tentatively made and sceptically received
Sociology of Modern Cosmology by Martin Lopez-Corredoira -- Abstract: Certain results of observational cosmology cast critical doubt on the foundations of standard cosmology but leave most cosmologists untroubled. Alternative cosmological models that differ from the Big Bang have been published and defended by heterodox scientists; however, most cosmologists do not heed these. This may be because standard theory is correct and all other ideas and criticisms are incorrect, but it is also to a great extent due to sociological phenomena such as the "snowball effect" or "groupthink". We might wonder whether cosmology, the study of the Universe as a whole, is a science like other branches of physics or just a dominant ideology.

11:59 AM: DNA analysis may be done on Mars for first time [by Ewen Callaway,, 9 Apr 2009.]
"Chemical signs of life can be ambiguous, but Ruvkun and his team hope to find its unequivocal signature by sending a DNA amplifier and sequencer to Mars in the next decade. They're betting that any life on the Red Planet shares an evolutionary heritage with life on Earth, and therefore contains a similar genetic code – a requirement that other scientists say is too narrowly focused, since Martian life may have evolved independently and therefore may have very different chemistry."

1:38 PM: Hi my colleague Barbie Drillsma met you at the AAAS meeting in Chicago and passed me your card as she said you had expressed some interest in involvement.

The brochure outlines a number of opportunities for involvement, but we are happy to discuss any other possibilities. Our website has plenty of detail on the programme and our supporters and can be found at Anyway I thought I would mail to follow up this initial contact and to see if you would like to discuss further opportunities for involvement with this international meeting of science journalists. All the best and I look forward to hearing from you soon - Sallie Robins | Co-Director, World Conference of Science Journalists 2009 and Communications Manager, The Big Bang

7:07 PM: Dear Sallie -- Thank you for your message. Yes I am interested in coming to your June meting. May I tell you more? I am (I now realize) a blogger on the subject of panspermia. The version of panspermia I promote pertains not only to the origin of life on Earth, but also to evolution. My work gives me a rare perspective on the well-advertised debate between evolution and creationism/ID.

I have come to believe that science journalists usually do a terrible job on the subject of evolution. They are more like cheerleaders for the darwinist position. I believe they should be more like political reporters, who don't just automatically believe what the politicians tell them. Political reporters are often very well-informed, so they are able to probe and challenge and sometimes eventually help to uncover to the truth. (And evolutionary scientists are like politicians -- their jobs are at risk.)

While I think creationism/ID has no scientific answers to offer, I think the issues it raises are often real. That is, I think the mainstream theory of evolution has very major shortcomings. Perhaps these can be overcome, but so far the evidence is lacking. Meanwhile, the superficiality of the debate is severely hindering scientific progress.

I would like to opportunity to make a case like this to some science journalists. I would urge them to ask probing questions, and not to presume that science has no self-interest to protect. I could prepare a presentation with discussion to follow, or I could participate in some other way that would afford a similar opportunity.

My main interest is panspermia, but this would not be any kind of hidden agenda. After a short confession, my subject would be strictly as described above. I welcome the chance to discuss this further. Thank you. Best regards, Brig

Tuesday, March 03, 2009 12:26 PM: Many thanks for your response, unfortunately the programme is now fully formed, but of course we would welcome you attending as a delegate and of course then you can participate in the many debates and discussions that will take place both formally as part of the programme and more than likely late into the evening at receptions!
