Layi, I think Abiogenesis maybe the answer you are looking for. But to understand it, you first have to understand the meaning of "life". Life is defined as the specific position and movement of the quantifiable energy (Quantum State) which permits that some quasi-stable thermodynamism systems be structured and to establish autonomously a series of periodic intervals that delay the dispersion of diffusion of their internal energy to more available microstates.
From this definition, we can safely conclude that the quantum energy promotes a temporary delay in the increase of the thermodynamic systems’ local entropy through a set of physicochemical processes that confer autonomy to the whole system as a result of a specific position and momentum of that quantum energy. Quantum energy means any amount of energy that exists in discrete packages or “quanta”.
Before I continue to describe the scientific concept of life, let me call your attention to the words of Dr. Frank L. Lambert with respect to the real meaning of entropy, “Entropy is not disorder, not a measure of chaos, not a driving force. Energy's diffusion or dispersal to more microstates is the driving force in chemistry. Entropy is the measure or index of that dispersal. In thermodynamics, the entropy of a substance increases when it is warmed because more thermal energy has been dispersed within it from the warmer surroundings. In contrast, when ideal gases or liquids are allowed to expand or to mix in a larger volume, the entropy increase is due to a greater dispersion of their original unchanged thermal energy.” “From a molecular viewpoint all such entropy increases involve the dispersal of energy over a greater number, or a more readily accessible set, of microstates. Frequently misleading, order-disorder as a description of entropy change is also an anachronism. It should be replaced by describing entropy change as energy dispersal--from a molecular viewpoint, by changes in molecular motions and occupancy of microstates.” (Citation: Lambert, Frank L. J. Chem. Education, 2002, 79-187). What Dr. Lambert describes here is the real concept of Entropy established by the modern Physics and accepted by modern Physicists.
Life was an energetic possibility in the whole universe since the end of the inflationary period, some milliseconds after the big bang. The terrestrial living beings arose billions of years after the big bang (about 9,000 million years later). The elements were synthesized at the solar nebula thanks to the radiation emitted by the nuclear thermo-reactions of the young sun. Water and other short organic and inorganic molecules formed in the solar nebula, just when a fluctuation of the density of energy of the solar system allowed the elements to bond forming more-complex compounds.
Frozen dust at the protoplanetary nebula allowing the synthesis of organic compounds, for example, carbohydrates, ammonia, quinones, amino acids, lipids, glyceraldehydes, and globulins, into the grains of dust containing also icy water. Diverse chemical reactions that produced biomolecules could occur inside ice crystals embedded into fractals thanks to irradiation and uv photolysis. Perry a. Gerakines, marla h. Moore and reggie l. Hudson from the physics department of the university of Alabama, at Birmingham, Alabama, have experimentally confirmed the formation of organic molecules from frozen mixtures (at 20 -100 k) due to irradiation (0.8 mev protons) and uv photolysis (6-10 ev). This experiment supports the theory about the high probability of inorganic synthesis of complex biomolecules at the protoplanetary clouds, which contained frozen crystals of diverse materials, like water, methane, carbon monoxide, carbon dioxide, methyl, acetylene, sulfur dioxide, phosphate groups, etc.
Uv light, heat and gravitational, electromagnetic and electrodynamic forces caused the synthesis of complex carbohydrates, proteins, globulins, organic bases, phosphate groups, and lipids. The last can form simple bilayered membranes. Lipids and phosphate groups jointed as phospholipids and formed amphiphilic membranes that integrated as microscopic globules inside water drops trapped into grains of dust (fractals forming the planetary nebulas). This synthesis occurred into the planetary clouds; for example, the disk-like cloud in orbit around earth.
Jamie e. Elsila, j. Seb gillette, richard n. Zare, max p. Bernstein, jason p. Dworkin, scott a. Sandford and louis j allamandola from the department of chemistry of stanford university, at stanford, ca have demonstrated experimentally that the frozen grains of dust at 10-20 k can be photo-processed by uv light to form more complex biomolecules. This observable fact is known as uv-photochemistry of biomolecules and supports my theory.
Thanks to uv light emitted by the sun and the heat generated by multiple collisions between particles of the planetary cloud, after the planetary nebula cooled as much as necessary, more microspheres were synthesized, being limited spontaneously by membranes of lipoproteins. The microspheres contained a larger diversity of organic compounds and continued retained into the particles of dust (fractals) already orbiting as planetary atmospheres.
The grains of dust (fractals) acted as protective “eggshells” for the biomolecules against ionizing solar radiation and uv photolysis (remember that the dimension of the icy particles at planetary clouds fluctuates from a few centimeters to one meter in diameter). Therefore, chemical mutations permitted the synthesis of molecules still more complex of carbohydrates, proteins and lipids, which built highly stable and lasting membranes that wrapped the microspheres. However, those membranes were ephemeral by the intensity of the cosmic radiation that could destroy them; however, many microspheres enclosed by membranous vesicles subsisted under that hostile environment because they were held into solid grains of dust and water ice.
Due to their very low resistance against cosmic radiation, nucleotides only had resisted if they had been synthesized behind protective screens at temperatures lesser than 70° c; thus, it would not be possible the synthesis of dna at that moment. However, rna nucleotides would be able to keep stable at temperatures lower than 70° c.
Ultraviolet radiation, heat and inorganic chemical reactions promoted the synthesis of catalytic proteins. Later, these catalytic proteins directed the synthesis of short molecules of rna, then the synthesis of larger rna molecules that already could contain the encoded information for the synthesis of more catalytic proteins identical to the initial catalytic proteins in their molecular arrangement. The flexibility of this theory permits us to assume that the ribozymes were not central for the synthesis of catalytic biomolecules, which could replicate themselves in a similar way as prions replicate themselves.
The gravity force and the electrodynamic force coerced the small dust grains to form lumps (fractals), containing microspheres enclosed by membranes made of phospholipids, at the planetary orbits. They formed a very dense cloud of lumps of dust, water vapor, ammonia, methane, quinones, acetylene, carbon monoxide, carbon dioxide, sulfurs and other gases; however, the orbital angular moment of those particles and the intense heat irradiated by the planetary crusts prevented the grains of dust to fall down onto the planets’ surfaces.
Orbiting in planetary atmospheres, the microspheres agglutinated inside the grains of dust and liquid water to form the prebiotic structures called protobionts, which at that moment were not yet living forms, but limited by membranes of peptoglycan vesicles, into which happened few metabolic processes.
The subsequent chemical evolution directed the fusion of protobionts. One protobiont engulfed to other protobionts. The integration of molecules of proteins, nucleotides, carbohydrates, lipids, and other chemical substances to the protobionts’ plasma involved the formation of complex structures. Despite the fact that most protobionts did not persist for large periods, many assemblies of protobionts can maintained stable structures near the next and very important planetary event.
Fortuitously, only the protobionts that had formed in the protective planetary clouds (water vapor and dust clouds) persisted. Protobionts were the ancestors of archeobionts.
At this time, only those protobionts that possessed the adequate molecular arrangement experienced the energy state of life, thanks to a phase transition in the terrestrial nebula caused by a fluctuation in the density of energy in the solar system. As a result, the first living archeobiont appeared on earth. Archeobionts were the ancestors of all living beings that exist on our planet and, perhaps, on other world of our solar system.
Many thermodynamic and electrodynamic incidents occurred all through the integration of our solar system. The fluctuations in the energy density and a series of drastic phase transitions in the solar system as a whole were the most important episode. For the early period of nucleosynthesis, the intermittent emissions of particles -derived from nuclear fusions- generated fluctuations in the energy density of the system, besides the development of energy holes. We think that the molecules of the protobionts were excited at one of those spontaneous oscillations, so their internal energy acquired the indispensable positions and momentum that block for short periods its diffusion or dispersion toward more possible microstates.
When the crusts of the planets got colder and pluvial precipitations took place, the drops of water dragged the fractals enclosing archeobionts onto the surfaces of the planets. For this to occur, the orbital angular moment of the dust and gases cloud had to have diminished to a speed lower than the speed of the rotational movement of the primitive earth. This lessening of the orbital angular momentum of the grains of dust was possible thanks to earth’s gravity and the collisions of the lumps of dust between.
Once placed in planetary soils, bionts remained stable by means of staying behind protective screens, for example, the dense clouds of water vapor, icy water and dust of the planetary atmospheres. Billions of bionts were destroyed by the aggressive conditions of the planetary environment; however, when the planets got colder enough and the sun got more stable, bionts could remain as integral structures more easily. The difference consisted on having or not each factor essential to confer them more resistance against the hostile environment, and to prevail under the pressure of the fundamental natural selection caused by the environments of all the primitive planets. I should clear up that in agreement with this theory, only was needed a viable biont to generate all the living beings that have existed and exist on our planet.
Protected by a sky full up with dust, water vapor, hot volcanic ashes and diverse vapors, submerged in deposits of water at no more than 36° c, the bionts can reproduce themselves generating more living molecular systems. Apparently, the earth was the unique planet in our solar system with all the favorable conditions for bionts survival. The emission of particles from the sun propitiated the biotic energy field, or life (the term “biotic” refers to any thing related to life, the term “abiotic” to any inert thing, while the term “biont”, whether used like substantive or as a suffix, refers to any living being).
Here is what is deemed to have occured during the solar fluctuations of energy. 1. The arrangement of simple molecules in molecular more complex structures (microspheres) in the solar nebula. 2. The adhesion of complex molecular structures (microspheres) in the planetary nebulas forming microspheres enclosed by membranes. 3. The fusion of multiple and diverse microspheres enclosed by membranes forming protobionts or coacervates. 4. The induction of those conglomerates toward an energy state that induced those conglomerates to produce no-spontaneously intervals in the dispersion or diffusion of their internal energy.
These four energy processes converged in earth. However, we cannot exclude other planets of our solar system like probable hosts of living beings. The divergences that could have occurred at other planets of our solar system correspond to times, places and events that continued after the energy fluctuation that generated the autonomy of some molecular arrangements. Perhaps, the first primitive living organism did not need organic or inorganic sources of chemical energy. Perhaps the first biont can capture energy and simple chemical substances directly from the environment to elaborate the necessary structures for its subsistence.
The first living thermodynamic system could have been a myxotrophic (able to take energy both from radiation emitted by the sun and from chemical substances) and hyperthermophyllic (resistant to extreme high temperatures) organism. However, the contemporary hyperthermophylles are not equivalent to those primitive bionts. The current hyperthermophylles (which tolerate more than 70° c) evolved from a later group called archaea, which evolved from chemosmotic primitive bionts.
Recently, some scientists have found bacteria from the group archaea that survive to very low temperatures, under antarctic glacial. All these recent discoveries will turn out an unyielding competition between adherents of the smoldering origin and the fans of the frosty origin to find out which one of them had the reason, if the followers of the scorching origin of living beings or the followers of the frosty origin of living beings. However, the theory is clear at this issue: the first living organisms synthesized spontaneously in the warm (not too cold, not too hot) environments formed by the clouds of dust and water. Let us say, into gentle surroundings, which temperatures should not reach up to 36° c.
Has this helped? I don't know. Should you require further research material, let me know and I could send you some by FEDEX or DHL. I apologise for the very long post
