The Major Transitions in Evolution Revisited
13 September 2013
A major problem with all origin-of-life theories — how did biological "self-preservation" arise? — is something we should not continue to ignore, according to Australian philosopher Pamela Lyon:

"...Let me be clear: I do not doubt that self-preservation—the inchoate striving to maintain system integrity against threat and to perpetuate existence via reproduction—is the default existential condition of living things, present and past. But the emergence of that default state needs to be explained. This is the truck-sized gap in the origins and transitions narratives that Dawkinsian selfishness obscures." (p 107)

Lyon's essay is among fourteen in a collection that followed a workshop at the Konrad Lorenz Institute for Evolution and Cognition Research. The workshop, held in 2007, was designed to extend the research project promoted by John Maynard-Smith and Eörs Szathmáry with the publication of The Major Transitions in Evolution, in 1995. We think Lyon's essay does an even worthier thing — it exposes a questionable, basic assumption. We notice another questionable, basic assumption — life "originates?" The evidence, at least, has train-sized gaps.

Pamela Lyon "To be or not to be: Where is self-preservation in evolutionary theory?" p 105-125 in B. Calcott and K. Sterelny, eds., The Major Transitions in Evolution Revisited, ISBN:9780262015240, MIT Press, Apr 2011.

Metabolic systems ...contain a latent potential for evolutionary innovations with non-adaptive origins. Our observations suggest that many more metabolic traits may have non-adaptive origins than is appreciated at present. Two bioinformaticians observe that bacteria are "pre-adapted" for nutrients they may have never encountered. Using computers to analyse existing genomic sequences, they showed that, among strains of E. coli that can metabolise glucose, 96% can metabolise other nutrients, up to as many as 44 out of the 50 nutrients considered.

Traits with "non-adaptive" origins are hard to explain with the mainstream theory of evolution. But genomes with programs that are "pre-adapted" for unencountered situations are a standard prediction of cosmic ancestry. The report of this analsis concludes, ...The pervasiveness of non-adaptive traits may require a rethinking of the early origins of beneficial traits.

Life on Earth may have come from Mars, according to Steve Benner, biochemist and founder of the Westheimer Institute of Science and Technology in Gainesville FL. He notes that minerals containing boron and molybdenum would have been more abundant there, and these may provide templates that might help to sort out any prebiotic soup. Steve Benner

"Basically, we went looking on Mars because the origins-of-life options on Earth just aren't looking very good," Benner said. For whatever reason, the story is getting a lot of coverage. Of course, if life came to Earth from Mars, that is called panspermia. Welcome aboard, Steve!

SPIE Astrobiology XVI will take place Tuesday, 27 August 2013, in San Diego, California. Some of the world's leading experts, including conference co-chairs Richard Hoover, Gil Levin, Alexei Rozanov and Chandra Wickramasinghe, will discuss the latest developments in astrobiology. Of special interest to us, the international team studying the Polonnaruwa meteorite that fell 29 Dec 2012, will present evidence for life in it. At an evening session (8-10 PM, Marriott Hotel, Marina E), conference panelists will recap some of the news and answer questions from the audience. The evening session, titled "Life in the Cosmos," is open to all; science reporters are especially welcome.

diatom fragment recovered 31 July 2013
10 August 2013
British astrobiologists have recovered a diatom fragment from 25 km high in the atmosphere, with balloon-borne equipment flown from Chester, NW England, 31 July. The biological nature of the fragment is beyond doubt, and the report makes a strong case for its arrival from space. Testing the particle's isotope ratios could discern its provenance, but this requires a special mass spectrometer. Grant money for this investigation is available, if a NanoSIMS or equivalent facility becomes interested.

Did NASA's Opportunity rover find evidence for life on Mars in 2004? A fossil photographed in Meridiani Planum on Sol 34 of that mission looks to several experts like a fossilized crinoid, a primitive sea animal related to starfish and sea urchins. But within 3 hours of taking the photo, NASA used the Rock Abrasion Tool (RAT) to completely obliterate the likely fossil. Why did they not, instead, take more photos from other angles, at different times, etc., and then deploy appropriate experts to examine the photos? And/or look for anything similar in the vicinity? Does NASA really want to know if there is, or ever was, life on Mars? It seems not!
fossilized crinoid on Mars? erased fossil on Mars
The Microscopic Imager camera on Opportunity took three nearly identical photos within less than 5 minutes including this photo at 11:30:35 local solar time on Sol 34. The fossil, with several features characteristic of crinoids, is visible just left of center. [NASA source image and legend] (We estimate the picture width at 3.5 cm.) The same camera later took three more photos in succession including this photo at 14:31:53 on Sol 34. With the RAT, NASA has ground away the fossil and nearby raised features, and the debris has been swept off. The surrounding "blueberries" now appear as dark circles. [NASA source image and legend]

P. salinus genome Giant viruses, bigger than many bacteria, have been discovered by French biologists. One species in salt water off Chile, and one in fresh water in Australia, had dsDNA genomes of approximately 2.5 and 1.9 million nucleotide pairs, respectively. The new viruses have been designated Pandoraviruses. "Both pandoraviruses lack genes for energy production and can't actually produce a protein on their own, fulfilling the definition of virus." The larger one, P. salinus (genome illustrated) has 2,556 likely protein-coding sequences (CDSs). Only 7%, have recognizable homologs. "What the hell is going on with the other genes?" Another big surprise for darwinism, and perfectly welcome news for cosmic ancestry.

In the figure, the concentric circles represent: 1, CDSs positions on the direct (blue) and reverse (red) strands; 2, CDSs with a best match within eukaryotes (orange), bacteria (green), and viruses (purple); and CDSs with MORN repeats, ankyrin repeats, and F-box domain motifs (white); CDSs with no match (gray); 3, CDSs whose protein products were identified in the proteome of purified P. salinus particles.

Pseudomonas Bacterial DNA in human genomes is confirmed. Bacterial genes in humans were already noticed, in 2001, when the the human genome was sequenced, but that surprise was subsequently disputed. The new data seem sure. The evidence comes from the University of Maryland School of Medicine, and the transferred sequences are apparently more prevalent in cancer cells. (Pictured: one donor species, pseudomonas.)

In cosmic ancestry, new genetic programs must be acquired by some form of horizontal gene transfer (HGT). The observed bacterial DNA was apparently acquired through an RNA intermediate. After transfer, newly acquired genes need testing and optimising. Sometimes they will turn out to be useless or even harmful. The harm may be manifest as cancer. Or perhaps cancer cells are more likely to acquire new genes. These examples are seen in somatic cells, but HGT often also reaches germline cells, as the report mentions. The news from Maryland is entirely plausible to us.
