Quote:Current models
There is no single, generally accepted model for the origin of life. Scientists have proposed several plausible hypotheses, which share some common elements. While differing in the details, these hypotheses are based on the framework laid out by Alexander Oparin (in 1924) and by J. B. S. Haldane (in 1925), who postulated the molecular or chemical evolution theory of life.[105] According to them, the first molecules constituting the earliest cells "were synthesized under natural conditions by a slow process of molecular evolution, and these molecules then organized into the first molecular system with properties with biological order".[105] Oparin and Haldane suggested that the atmosphere of the early Earth may have been chemically reducing in nature, composed primarily of methane (CH4), ammonia (NH3), water (H2O), hydrogen sulfide (H2S), carbon dioxide (CO2) or carbon monoxide (CO), and phosphate (PO43−), with molecular oxygen (O2) and ozone (O3) either rare or absent. According to later models, the atmosphere in the late Hadean period consisted largely of nitrogen (N2) and carbon dioxide, with smaller amounts of carbon monoxide, hydrogen (H2), and sulfur compounds;[106] while it did lack molecular oxygen and ozone,[107] it was not as chemically reducing as Oparin and Haldane supposed. In the atmosphere proposed by Oparin and Haldane, electrical activity can produce certain small molecules (monomers) of life, such as amino acids. The Miller–Urey experiment reported in 1953 demonstrated this.
Bernal coined the term biopoiesis in 1949 to refer to the origin of life.[108] In 1967, he suggested that it occurred in three "stages":
the origin of biological monomers
the origin of biological polymers
the evolution from molecules to cells
Bernal suggested that evolution commenced between stages 1 and 2. Bernal regarded the third stage – discovering methods by which biological reactions were incorporated behind a cell's boundary – as the most difficult. Modern work on the way that cell membranes self-assemble, and the work on micropores in various substrates may be a halfway house towards the development of independent free-living cells.[109][110][111]
The chemical processes that took place on the early Earth are called chemical evolution. Since the end of the nineteenth century, 'evolutive abiogenesis' means increasing complexity and evolution of matter from inert to living state.[112] Both Manfred Eigen and Sol Spiegelman demonstrated that evolution, including replication, variation, and natural selection, can occur in populations of molecules as well as in organisms.[51] Spiegelman took advantage of natural selection to synthesize the Spiegelman Monster, which had a genome with just 218 nucleotide bases, having deconstructively evolved from a 4500-base bacterial RNA. Eigen built on Spiegelman's work and produced a similar system further degraded to just 48 or 54 nucleotides – the minimum required for the binding of the replication enzyme.[113]
Following on from chemical evolution came the initiation of biological evolution, which led to the first cells.[51] No one has yet synthesized a "protocell" using simple components with the necessary properties of life (the so-called "bottom-up-approach"). Without such a proof-of-principle, explanations have tended to focus on chemosynthesis.[114] However, some researchers work in this field, notably Steen Rasmussen and Jack W. Szostak. Others have argued that a "top-down approach" is more feasible. One such approach, successfully attempted by Craig Venter and others at J. Craig Venter Institute, involves engineering existing prokaryotic cells with progressively fewer genes, attempting to discern at which point the most minimal requirements for life are reached.[115][116][117]
The NASA strategy on abiogenesis states that it is necessary to identify interactions, intermediary structures and functions, energy sources, and environmental factors that contributed to the diversity, selection, and replication of evolvable macromolecular systems.[118] Emphasis must continue to map the chemical landscape of potential primordial informational polymers. The advent of polymers that could replicate, store genetic information, and exhibit properties subject to selection likely was a critical step in the emergence of prebiotic chemical evolution.[118]
Sometimes I wonder if you actually read the links you provide. If you will read the part in bold face you will realize that they render the rest of the article as a bunch of rhetoric that draws conclusions without any supporting data beyond pure speculation. And by definition believing something on pure speculation is believing something on faith and faith alone,
In the first bold faced quote they say people have provided plausible hypotheses but, in the second boldfaced quote they say nobody has been able to replicate these hypothesis. To be plausible the hypothesis needs to be probable. If we can't replicate any of the hypothesis for abiogensis using our intelligence, how could nature replicate it with no intelligence. The data suggests that to replicate abiogenisis it takes more intelligence and/or greater physical abilities than we have, not less. Otherwise, we should have been successful at replicating abiogenisis. Wouldn't you agree? If you don't agree could you explain why my assumption isn't logical.
Even NASA is trying to use human intelligence to identify a very complex system because they know, "it is necessary to identify interactions, intermediary structures and functions, energy sources, and environmental factors that contributed to the diversity, selection, and replication of evolvable macromolecular systems.[118] Emphasis must continue to map the chemical landscape of potential primordial informational polymers. The advent of polymers that could replicate, store genetic information, and exhibit properties subject to selection likely was a critical step in the emergence of prebiotic chemical evolution".
Now there's NASA stating the obvious. How big of a brick do they need to hit us over the head with suggesting that maybe it takes more than luck for that paragraph to happen.
