Here are another examples, among multitudes, which show realism (existence) of biological processes organizations and of biological information, and therefore, which give evidence of a common language to beings :
* Naturally, the genetic code.
"Today, all alive bodies are made by one or several cells, surrounded of membranes ...
All organisms utilize DNA as reproductible memory of genetic information, all are expressing this information by transcription of the DNA on RNA and all convert RNA in the proteins by the same mechanisms, including, except for of rare relatively recent exceptions, by the same genetic code.
All utilize the same basic processes of combine so as to transmit their information.
All make the same kind of complex metabolic reactions built around a common nucleus and catalysed by of big proteic enzymes which generally are composed by several hundreds of amino acids and coenzymes of which several are universally distributed … ",
"Appearance of RNA is considered as a key-event which divides the protometabolism into two periods : before-ARN where dominates exclusively chemistry, and after-ARN where selection adds itself to chemistry ... " (Cf. Singularities – C. de Duve – Nobel).
Although it is necessary for understanding life's dynamics, this analysis cannot however satisfy philosopher and theologian.
Indeed, selections presuppose of faculties of transcendent order, that enable recognitions, judgments, … and choices ; it's an essential necessity which never is discussed, even, always ignored.
Observe, even if genetic code is sometimes object of peculiarities,
it is unanimously recognized universal, structured, combinatorial, optimized at best,
so many characters which show that it is not fact of accidental processes, hazard's product or fruit of a natural selection.
For example, let’s consider optimization ; although there is at genetic level, a redundancy of the information and processes organizations,
- optimization of the genetic code presupposes more than selections : a same operator and an intention which is according to us, associated to a necessity,
- let's repeat again, the information and the processes organizations necessitate ceaseless taking into consideration of numerous value references, notably, the durations.
Genetic replication is, too, particularly rich for quest of primordial causes.
So, even if DNA replication is made in a similar way to the one of the RNA, this replication shows a research of more reliability.
According to C. de Duve :
"DNA replication is subjected to a supplementary control by of specific enzymes which detect and suppress a large part of the erroneous assortments .... With this control, the exactness of DNA replication enormously exceeds the one of the RNA, reaching the rate of error fantastically low of one desoxynucleotide incorrectly inserted on approximately a billion." (Cf. Singularities).
Consequently, what is creative entity who is responsible of this process because, naturally, enzymes do not control ?
Enzymes, specific molecular structures, sometimes enable verifyings, what is quite different.
As for expressions of the life's phenomenon, if they are various and interdependent in this world of sacrificial character, is not it because of a primordial necessity which incites to creations, of an universal freedom and inexorable constraints (impossibilities) ?
Why not to say anything about this mysterious, imperious and universal need to create ?,
who can ignore the universal constraints associated to freedoms ?
* "Migration road of the cells" and "specialization of the cells".
We know that this road is not very important because the all new cells are the same ; they "settle" there where they are necessary and there where they are asked.
These almost immediate adaptations, made without errors, therefore show that extremely quick precise processes organizations,
are transmitted with of specific vectors of the sense, (by a language) until elementary levels of the beings.
* The genetic abnormalities, as the drepanocytic and thalassemia, which protect from malaria given by the Plasmodium falciparum, a parasite conveyed by mosquitoes.
Do you believe that it is only of light variations of the genetic characteristics (physico-chemical) which enable from neutralizing the malaria ?
We do not think.
The genetic characteristics are more than physico-chemical : they include biological processes organizations of transcendent order.
* Among the singular languages within body, let's quote too, deadly biological processes organizations which are necessary for beings's development.
