The Evolution Big Lie; Evolution Proves Metapysical Nauralism

The purines and pyrimidines used in nucleic acid synthesis


Now for those who may still be scratching their heads. Let us suppose for the moment that abiogenesis is true and that all 17 of life's amino acids that can be synthesized in experimental apparatuses were either present on Earth (the 6 durables) and/or delivered to Earth via the rain of space debris that occurred near the end of the solar system's primordial period. Life initially got by on these 17 and acquired the other three later. Check?

But here's the problem: realistically, life could have only gotten by at first on the 6 durables and would have had to pick up the other 14 later. Why? Because the others cannot maintain their compositions for any significant length of time outside living cells or encapsulated deposits. Readily assessable concentrations of them are never realized in nature. Nature could not have aggregated and polymerized isolated organic molecules, let alone go on from there to replication and recombination, and from there to transmutation and realization. Indeed, how could nature have gotten off the ground at all, starting with aggregation, when it only had at best the 6 durables in racemic mixtures to work with?

But more to the point, from my article:

Since Miller-Urey, the discoveries of biochemistry and microbiology have revealed precisely why the synthesis of life out of amino acids from the ground up is a dead end. Mere chemistry does not produce life; only complex structures produce life. Amino acids simply do not link up in nature to form proteins, not even when they are let loose in a pristine brew consisting of only left-handed ingredients. Without high-energy compounds and enzymes, amino acids do not form the many peptides and, therefore, the many proteins needed for life. But the most significant prerequisite of all is information, and that information resides above the chemical properties of amino acids.

. . . Hence, no matter how many experiments were conducted by planet Earth and no matter how many more particulate chemicals She might have had at Her disposal, there is no way that amino acids fabricated the hundreds of thousands of proteins that are found in living organisms. It takes more than a random collection of amino acids to make life. They must be assembled in a very precise and elaborate fashion in order to perform useful or desirable functions. Without the necessary information contained in preexisting nucleic acids, the result would be a collection of gobbledygook, and nucleic acids cannot evolve without the infrastructural and catalytic properties of preexisting proteins.

In other words, DNA synthesis relies on the presence of infrastructural and enzymatic proteins, and protein synthesis relies on the encoded genetic information in DNA and on the coded translations of that information in RNA. What we have here, at least with respect to the origins of DNA, is an interdependent circle of irreducible complexity. —M. D. Rawlings

Hence, abiogenesists turned to the RNA world hypothesis and the various metabolism-first models thereof entailing the supposed machinations of smaller compounds containing catalytic properties and information. But of course, nature would have to get off the ground with the precursors of the pertinent nucleic acids, just for starters, for there is yet another wall that nature runs into after that.

So once again, orogenicman, are you yet ready to move on to the actualities of these outside of controlled/experimental conditions? . . .
