Nano-Review of "The Story of Earth" by Hazen | from James Powers | 04 Sep 2018

Hi Brig, I just finished Hazen's book.  My nano-review:
I liked the beginning few chapters and I liked the last couple of chapters.  I have issues with what is between.  It is a well written, informative, entertaining book that represents the mainstream state of the science. I appreciate that there are no footnotes or references.  However, I have issues with his interpretation of the facts and his assumptions.  He is a rock-ologist and I am a bug-ologist; we don't see eye to eye.

My issues require a longer analysis.  There is new information for me to digest.  I agree:

  1. No Late Heavy Bombardment.  Let's put this myth to rest.
  2. The original atmosphere was composed of CO2 & Nitrogen & trace SO2 at high pressure.
  3. He writes an amazingly vivid description of the Big Thwack and the Hadean Era Lunar tides in magma.
  4. His discovery and description of the 2/3rd's new minerals formed due to biological oxygenation activity.
  5. He invokes Lynn Margulis.  Unfortunately, he doesn't really understand what she represents.
  6. He presents an excellent biography of Albert Wegener.  I didn't realize that he was a meteorologist, not a professional geologist.
  7. He trashes Urey & Miller and the stifling authoritarian opinion that dominated astrobiology for so long.
  8. He includes stable isotope analysis (C13/C12 ratios) of various environments and eras.
  9. He includes future Ice Ages in his predictions
  10. He is modest, writing that he is a geologist and not a chemist or biologist.  He admits that a scientist will bias his profession when analyzing and publishing data. I like him and his personal stories.
I don't like:
  1. His analysis of Limestone Rock.  He assumes that there are two kinds of limestone, biological fossil remains and non-biological, "inorganic" limestone.  I think that all limestone and CO2 has been a part of the biological cycle, which include CO2 (and H2O) cycled through the many tectonic cycles.
  2. He believes that the original atmosphere was composes of a partial CO2 pressure about 30-40 bar.  I believe that the original CO2 atmosphere was >100bar and the CO2 at the surface was a supercritical fluid.
  3. He believes that water and hydrogen were released slowly, oozed from the mantle and formed the early prebiotic oceans.  These were a component of the atmosphere and meteorology of the era.   I think that by the time that the Earth cooled almost all of the volatiles were "cooked" away and were lost to outer space.
  4. Of course, he believes that life originated in the ocean depths near "black smokers."  I think that extremophile anaerobes inoculated the early earth atmosphere and through the Wood-Ljungdahl pathway rapidly removed huge amounts CO2.  The other byproduct, water at least partially formed the oceans.
  5. I object to his use of "Darwinian Evolution" as an integral part of the definition of life.  I do not use that term.
  6. He does not mention Carl Woese or Archaea. The biological tools that are found in contemporary extremophile archaea and bacteria are in effect relict tools of an ancient Hadean history.
I hate:
  1. I hate his C13/C12 Stable Isotope analysis for defining microbiological activity.  This really "bugs" me.  He assumes that the PDB C13/C12 standard is an indicator of inorganic non-biological activity.  wrong, Wrong, WRONG!  He squashed one scientist's paper about the identity of a black layer in sandstone that she thought was biological in nature, but he enforced his incorrect analysis.  The publication was withdrawn.  To be explained later.
Thanks for the recommendation. "The Story of Earth" is important required reading in order to understand the mainstream paradigm. As a piece of scientific literature, it is a very well-told story.  There are important objections contained within that I had not previously considered and they are now resolved. Talk to you soon.

The Story of Earth by Robert Hazen, Penguin Books, 30 Jul 2013.

05 Sep 10:48AM I do need to explain my Stable Isotope objection.  FYI – The moon, comets, chondrite meteors and the solar photosphere all have a dC13 ratio much higher than the Earth.  I assume that the first atmosphere also had a ratio that reflects the solar system C12/C13 ratio.  It is larger than the Peedee Bentonite Zero Standard.  I haven't calculated yet, however I think with a couple of assumptions, I can estimate the amount of Carbon stored in the Earth's crust.

Liquid Water Lake on Mars | from Richard Hoover | 25 Jul 2018

Astronomers are now making comments about it being too cold (except the water is liquid) and too salty (Except halophilic archaea growing in supersaturated brines) for life. These astronomers apparently have no knowledge of microbial life in Cryopegs or in Don Juan Pond of Antarctica.
We interpret this feature as a stable body of liquid water on Mars, the related story, posted 25 Jul 2018.

Contact-binary comets | from Dave Carlson | 24 May 2018

Dear Brig Klyce, I greatly admire your website. I particularly like the article, Metazoan Genes Older Than Metazoa?  I suspect the anomalously-old convergence date based on gene divergence is telegraphing something more profound than we yet realize.
I recently read, Cause of Cambrian Explosion -- Terrestrial or Cosmic?, which discusses the importance of radioactive melting of water ice in large minor planets >1000 km. I spy another 'aqueous differentiation' (melting of water ice) mechanism inadvertently revealed in a recent arXiv publication:
The Plutino population: An Abundance of contact binaries (2018) suggests that a sizable fraction of Plutinos, and by extension other minor planet populations, have experienced binary merger, which would catastrophically melt saltwater oceans in their cores, albeit briefly following binary merger.   The Jupiter-family 'rubber ducky comet', 67P/Churyumov–Gerasimenko, is the poster child of contact binaries.
I've long suspected that the prevalence of contact-binaries in the asteroid and comet population, and now Plutinos, are evidence for minor planet formation by gravitational (streaming) instability, which tends to form similar-size, similar-color twin-binary pairs in wide binary orbits. Then wide binaries presumably evolve into contact binaries by way of sustained orbital perturbation, causing gentle binary spiral-in mergers, as over against orbital collisions, which cause craters and fragmentation.
contact binaries presumably  by binary spiral-in mergers, by way of sustained orbital perturbation. In the case of Plutinos and KBO cubewanos, the relevant orbital perturbation presumably occurred during the late heavy bombardment.

indisputable? | from John Lattanzio to Ted Steele et al. | 20 May 2018

Hi All -- to describe octopuses origins beyond the Earth as "indisputable" seems to be a bridge too far....!
I would say its not impossible and may be plausible. But far from "indisputable"..... Am I missing something??
Again - as someone new to the field - claiming beyond what can be truly defended to a skeptic does not do any good. If ne claim is seen as rubbish then people don;t listen to the rest. That is bad...
The fault is theirs! But humans are humans....we have to work with them :-)

20 May 2018 | 3:44 AM | from Ted Steele
Dear John: I think it is very important to read our paper very carefully as it reviews and deduces the most parsimonious conclusions from the data. https://doi.org/10.1016/j.pbiomolbio.2018.03.004
It is a paper of deep analysis for communication to all scientists in plain English prose. We have made that very clear up front and throughout the tortuous peer review process which took 12 months. We do not pull our punches, and I personally will not now.
For me, at this stage of this decisive debate - as that is what it is now - a very real and deep Paradigm Shift is underway globally ( I have been involved in these and it is now a no holds barred fight as they always are like this). This cannot be avoided in a battle of fundamental ideas as big arrogant egos and noses are being soundly put out of joint -scientific power cabals are being exposed -  and  the "Emperor is not wearing any clothes."
It is not everyone's cup of tea, that is why the great bulk of scientists, running safely with the herd, do not make important discoveries, nor bring about Paradigm Shifts.
It is likely to get a little hotter but I can see this shift being completed in the same time frame now of the Wegener/Continental Drift/Plate Tectonics change in understanding in the Geophysical Sciences shifts, about 2-5 years.
In my  view "Extraordinary evidence requires a complete rethink and then requires an extraordinary explanation" - this reverses the oft used skeptical mantra " Extraordinary claims require extraordinary evidence". It needs reversal here because the extraordinary evidence now exists.
Here are just two examples from our paper, which are paradigm shifting (that is, pure nonsense under the dominant terrestrial neo-Darwinian paradigm):

1. The Murchison meteorite (landed in Murchison, Victoria in 1969 and was immediately recovered, and curated in the city museum in Melbourne). It has eukaryotic fossils, at > 4.5 billion years old - older than the Solar System. EM Scans of internal sliced structures independently assessed by highly reputable workers show distinct biological cells and microfossils (some look like fruiting bodies typical of slime molds). A critic must now give an explanation that avoids Panspermia for that finding. There are other carbonaceous meteorites with microfossils examined the same way. Contamination has been ruled out (Pflug and Heinz 1997, Hoover 2005, 2011, Miyake et al 2010). Thus eukayotic life is external to the Earth and at least >4.5 Billion years old.

2. The infra red extinction spectrum for interstellar cosmic dust in our Milky Way galaxy has the same signature as freeze dried E. coli (a common complex living cell). All our knowledge of the Universe, delivered by the scientific discipline of "Astronomy" has been built this way - get the spectrum (emission, absorption) in the laboratory on Earth- then focus the telescope on a cosmic source/object and ask - What is the spectrum or signature?  Does it match that found in the Earth-based laboratory? All our chemical and physical knowledge of the Sun, other planets, comets, other stars etc. has been built up this way. Newton built his grand synthesis that way. As did Galileo and Kepler. Hoyle and Wickramasignhe predicted the match before they secured the astronomical observations (with Chandra's brother Dayal Wickramasinghe and DA Allen at the ANU in Canberra):

Extinction spectrum toward galactic center

The same match is seen in cometary ejecta tails (Halleys). We cover all this in the review (see Fig 1 and associated text, Hoyle et al 1982, 1984, Wickramsinghe DT and Allen 1986). Again, a critic must provide a better explanation that avoids Panspermia, that is , better than that published by Hoyle, Wickramasinghe et al. In 40 years no astronomer or physicist has provided a better explanation, but many astronomers have observed the match. It is an exact match - you cannot get better than that in Science.

I got involved with Chandra and his colleagues because I knew that anyone calling themselves a "Scientist" and  looking at the "extraordinary data" with a purely cool objective eye would draw the same conclusions as me. As a biologist am deeply immersed in RNA and DNA editing mechanisms, the Octopus RNA editing data reported last year ( I was at the GRC meeting and know the group) now place the Octopus in the class of "extraordinary genetic data"- so while some may want to pull their punches, I certainly won't. Now is not the time to be timid, as we have not published a timid paper. The prescience of the Russian space scientists detecting bacteria ( their DNA sequences)  in the cosmic dust on the external surface of the ISS is another class of "extraordinary data" ( as is the Tardigrades).
I thought it important that at this moment you be aware of my views on this. Best and thanks.

from Lattziano | 8:59 PM: Its a scientific discussion. Not a war. JL

from Dayal Wickramasinghe | 21 May: ...Here is how I see it (others may have different ideas).

It is possible to find non biological explanations for almost all aspects of astronomical data relating to interstellar dust when looked at in isolation. This is manly because we only have remote spectroscopic /extinction observations to play with. We have acknowledged this in our paper.

The question then is are the non-biological interpretations more plausible? We have discussed some of these and their short comings in our paper. In assessing  the relevance of the biological interpretation we have to draw on the many arguments put forward by HW over the decades. The "recent" discovery of large  numbers of "Earth type" planets in habitable zones makes the Copernican argument very strong.

The question then boils down to how much of the stuff out there COULD be of biological origin. If we bring in the detritus of biology into the picture (and the missing dust issue) plausibly a good proportion of it. It is hard to tell. Then comes the million dollar question - what is the source of  this material assuming it exists? In our paper we discuss Proto-planetary systems with comets as the major sites of replication. The studies of comets, starting with Haley, have provided some support for this hypothesis.

We need a smoking gun. Could come from in situ cometary studies or of studies of dust  falling on Earth. It may even come from studies of evolutionary biology on Earth as discussed  in the Steele et al. paper. ...Cheers, Dayal

from Chandra Wickramasinghe | 21 May: I agree with Dayal. But I must add that if there is a competition between biology and non-biology in producing organics, then it is biology that always wins. This is our experience on the Earth. Furthermore, there is no evidence worth anything that supports the standard story, and Earth-origin of life is beginning to look crazy; the oldest evidence of microbial life has been pushed further and further back to almost the time when the Earth's crust was molten (Australian outcrop data, 4.2 billion years ago). And despite billions of dollars worth of effort no success in abiogenesis experiments in the laboratory. The other point is that even if life started miraculously on the Earth, it is inevitable that it is now spread from Earth throughout much of the galaxy. Episodes of impacts on the Earth splashing out biomaterial is well documented, and the solar system has come within shooting distance of very many exoplanets/protoplanets in the 240 million orbit around the galactic centre.

So my point is "life anywhere means the same life everywhere", and life must be a galactic/cosmic phenomenon with a deeply connected biosphere.  

But of course we must all work within the constraints of the sociology of science. The "band wagon" has a momentum that takes much effort and persuasion to stop....

from Brig Klyce | 21 May: Dear John et al. – I apologize if this is intrusive, but, if life on Earth arrived by panspermia, the neighboring planets would have also been exposed. So there would be evidence of at least past life like ours on Mars, for example. For this I think there is a smoking gun, the fossil photographed on Mars by the Microscopic Imager camera of the Opportunity rover on 27 Feb 2004. The list of features, in my opinion, leaves no room for "reasonable doubt." (Segmenting, branching, triangular crotch, cup or "crown" structure enclosing something granular, similar sizes, and – newly noticed, to me at least – a calyx and remnant stalk.) John, if you are not aware, please take time to look. Croppings, text and original photo posted or linked at http://www.panspermia.org/whatsnew83.htm#20151028, recently updated.

That said, I agree, the gentler tone will not weaken the case. Thanks, all.


first civilization | from George Nickas | 20 Apr 2018

Brig, the question posted on Panspermia about another civilization on Earth pre-dating our own is interesting but a better question is how many civilizations have there been in the universe, which pre-date our own. The sheer statistics of it I believe suggest that humans are likely very much a johnny-come-lately in the vast arena of the cosmos. Here is one such answer to the question supporting that view.
