If living matter which is made from atoms and molecules, didn’t come from non-living matter, also made from atoms and molecules, where did it come from? Out of empty space?


Louis Charles Morelli Louis Charles Morelli - 8/25/2017

luvdomus: Forget the word “living”, which is antropomorfism, and things becomes clear. From Nature perspective, must say “systems”.

You are thinking in “atoms and molecules” as portion of organic mass coming from non-organic mass. Of course, a biological system can not comes from non-organic portion of mass. But, see that portions of non-organic mass can belong to a natural system, like atoms, galaxies. Now we has a better question: biological systems came from a non-biological system?

We need think about the jump in complexity, which would be very big. And what could happens in the process of transition for such mutation. The most complex non-biological system must be a galaxy. Making comparative anatomy between the first complete working biological system ( a Eukaryota cell system) and a galaxy, it seems impossible the jump. But,… maybe we are not knowing what a galaxy is. Maybe our theoretical model, the nebular theory, the spontaneous and random formation of bodies, are so wrong as when we were believing that Earth was the center of Sun’s system.

That’s what lead me to recalculate this models from the perspective of a cell system and calculating reverse evolution. The results – called Matrix/DNA Theory – shows a theoretical model of – not galaxies – but, building blocks of galaxies, that are equal to the building blocks of DNA. So, like the essence of an organism is not the organism but its DNA – it is the DNA that is transmitted to offspring, not the organism – is possible that the essence of this galaxy – the Matrix, its kind of non-biological DNA – was inserted into terrestrial atoms, driving them to biological organization and finally, composing a working system, due water and its production: organic chemistry.

So, we still have only theories, to be tested. But, now, after fixing this mistake caused by anthropomorphism, we can suppose that it is possible: biological systems were produced by evolution inside and by galaxies, which building blocks are half-biological/half mechanical described by Newtonian’s mechanics. Welcome to the new Milk Way, our physical grand-grandmother. Now, about our consciousness, its origins, I make no idea… Again the jump in complexity from the human brain to consciousness is not astronomic… maybe is universally ex-machine.

New computational model of chemical building blocks may help explain the origins of life

“… it has remained a mystery what actions could then prompt short chemical polymer chains to develop into much longer chains that can encode useful protein information. The new computational model may help explain that gap in the evolution of chemistry into biology.”

TheMatrixDNA - 8/24/2017
From Matrix/DNA perspective, we would trying to insert light ( preference for natural light ) somewhere into the computational simulation. What informations does have these initial polymers? If not about themselves and maybe, the random event producing them? When growing to foldamers, it means acquiring more atoms: which information has the foldamers if not ” information about themselves plus information of atoms, which probable they already have? At this point they are still non-biological organization of matter. They are at the same level of minerals, rocks, sand… How could them to jump from here to an astonishing new complexity?
We have a model of the building block of astronomic systems and a theoretical mechanism that makes possible the information from these systems being transferred to terrestrial atoms through stellar energy, cosmic radiation, etc. It happens that the configuration of this astronomic system is exactly the configuration of a lateral base-pair of nucleotides. So,…

(not published due final of characters) … information from this astronomic system are enough for that jump, since it drives the foldamer polymer to assembling as a working system.

A good compilation of actual theories, copied here for further research:


Teorias sobre Origens da Vida

Origin of life

  1. 1. INTRODUCTION Several attempts have been made from time to time to explain the origin of life on earth. As a result, there are several theories which offer their own explanation on the possible mechanism of origin of life. Following are some of them: • Theory of Special Creation • Theory of Spontaneous Generation • Theory of Biogenesis • Theory of Biochemical Evolution • Theory of Panspermia • Deep sea hydrothermal vent theory
  2. 2. • All the different forms of life – created by God. • HINDU CONCEPT :- Lord Brahma- created the living world in one stroke. • CHRISTIAN & ISLAM BELIEF :- God created this universe, plants, animals and human beings in about six days. • 3 main postulates : – All different kinds of animals & plants were created at once. – All organisms were created in the same form in which they exist today. – Their bodies & organs have been designed to fully meet the needs of the environment. • It has no scientific basis.
  4. 4. • Living things originated spontaneously from inanimate objects. • It is also called abiogenesis or biopoesis. • Supporters :- Aristotle » Epicurus » Von Helmont • They believed » Insects arise from dew » Fish & frog from mud » Fly maggots from meat . • Opposers » Fransisco Redi » Spallanzani » Louis pasteur • The opposers disproved this theory. Redi’s experiment Pasteur’s experiment
  5. 5. •Proposed by Richter in 1865 and supported by Arrhenius. •Life had come to earth from other planets of the universe, in the form of resistant spores. •British astronomers Fred Hoyle and Chandra Wickramasinghe proposed: •interstellar dust and comets contain organic compounds. •comets, which are largely made of water-ice, carry bacterial life across galaxies and protect it from radiation damage along the way. • The 2005 Deep Impact mission to Comet Tempel 1 discovered a mixture of organic and clay particles inside the comet. Credit: Hoover/Journal of Cosmology Dr. Richard B. Hoover, an astrobiologist with NASA’s Marshall Space Flight Center published a paper on March 4, 2011, claiming to have found fossil evidence for cyanobacteria in an extremely rare class of meteorites, called CI1 carbonaceous chondrites .
  6. 6. SOME OTHER THEORIES……. • Theory of Eternity of life: Life only changes its form but is never created. It has no origin and has always existed. • Theory of catastrophism – modification of the theory of Special Creation. – States that there have been several creations of life by God, each preceded by a catastrophe resulting from some kind of geological disturbance. – Since each catastrophe completely destroyed the existing life, each new creation consisted of life form different from that of previous ones. – Main supporters : French scientists Georges Cuvier and Orbigney • Vitalism : – Only living tissue, by virtue of possessing some “life-force,” can produce organic compounds. – Supporters: Berzelius and Bergson. – The production of acetic acid, from its elements, by the German chemist Hermann Kolbe in 1845, disproved vitalism.
  7. 7. • Also known as Materialistic Theory or Physico-chemical Theory. • Proposed independently by a Russian scientist, A.I.Oparin, in 1923 and an English scientist, J.B.S Haldane, in 1928. According to this theory, • Life first arose from a collection of chemical substances by a progressive series of reactions. • Early Earth’s surface and atmosphere – radically different from today’s condition. • The primitive earth’s atmosphere -reducing type. • Solar radiation and lightning must have been the chief energy source for these chemical reactions. • The organic compounds gradually accumulated in oceans and formed a ―hot primordial soup‖ or ―hot dilute soup‖. • Also known as ―Darwin’s warm little pond‖
  8. 8. • Oparin proposed that the proteinoids, nucleo proteins and other organic and inorganic molecules aggregated and precipited in sea forming organized colloid aggregates called coacervates. • The coacervates were able to absorb and assimilate organic compounds from the environment in a way reminiscent of metabolism. • They divided by budding. • Oparin considered that the coacervates gave rise to primitive cells or Eubionts. • Sydney fox obtained proteinoid microspheres by heating a mixture of dry amino acids b/w 130 to 1800C and later cooling them in water. • It was similar to coccoid bacteria. Coacervates Microspheres
  10. 10. DRAWBACKS OF UREY MILLER EXPERIMENT • By examining rocks ―dated‖ to be 3.7 billion years old, geologists determined that earth had an oxygenic atmosphere. • Oxygen is an ―oxidizing‖ agent and would inhibit chemical evolution. • Experiment produced a mixture of right-handed & left handed amino acids, but in nature left handed ones predominate. • Now it is thought that the atmosphere of the early earth was not rich in methane and ammonia — essential ingredients in Miller’s experiments.
  11. 11. • Recently some scientists put forth a hypothesis that life originated near a deep sea hydrothermal vent. • Black smoker hydrothermal vent – first discovered vents – produced extremely hot water, 3500 C – not conducive to micro-chemical evolution. • Lost City hydrothermal field – Alkaline vents in mid- Atlantic ocean. – discovered by Kelley and others in 2000. – Much cooler- temp of water – 70-900C – They are porous,honey-combed with cavities. – The cavities are at a scale of 1 micron – the same size as a living cell. – The cavity walls are saturated with iron- sulfur(Fe-S) mineral catalysts.
  12. 12. H2 +CO2 simple organic molecule (CH4, formate & acetate.) Serpentinization :- chemical reactions between seawater and mantle rocks which contain large amounts of the mineral olivine (a Mg-Fe silicate)  H2O was reduced by Fe2 ; H2 & S released.  At the vent ocean interface sulphur precipitate, Iron, Nickel etc transition metal sulphides. They catalyse H2 dependent reduction of CO2 to CO CO + H2S CH3-CO-SCH3 (methyl thioester of acetic acid)  These activated acetic acid derivatives serve as starting materials for subsequent exergonic synthetic steps. Vent pores concentrated large molecules like nucleotides formation of RNA, DNA , proteins NiS FeS
  13. 13. RECENT DEVELOPMENTS – In April 2011, researchers in Italy found that if they mixed formamide, a simple chemical present in space, with material from a meteorite, and then heated the mixture, that they produced nucleic acids (building blocks of DNA and RNA), the amino acid glycine, and a precursor to sugar. – In February 2010 scientists at the Scripps Research Institute in San Diego announced that they have synthesized RNA enzymes, known as ribozymes, that can replicate themselves without the help of any proteins or other cellular components. – In May 2009, a team led by John Sutherland, a chemist at the University of Manchester in England discovered how the basic nucleotides (building blocks) of RNA could spontaneously assemble . He formed the RNA nucleotide ribocytidine phosphate from cyano-acetylene.
  14. 14. CONCLUSION • All the evidence gathered thus far has revealed a great deal about the origin of life, but there is still much to learn. • Numerous scenarios have been explored for many years, but there is still a large gap between what is known and what is unknown. • Because of the enormous length of time and the tremendous change that has occurred since then, much of the evidence relevant to origins has been lost and we may never know certain details. • Nevertheless, many of the gaps in our knowledge (gaps that seemed unbridgeable just 20 years ago) have been filled in recent years, and continuing research and new technologies hold the promise of more insights.
