Actualization (materialization) of potentialities is therefore an extremely mysterious phenomenon almost ignored of philosophers and theologians, and only some fragments are revealed by the life's phenomenon.
Thus,

- the totally dehydrated bacteria live again as soon as they are into their natural environment, and it although they have been frozen a long time, to very low temperatures. Indeed, dehydrated, they are inert carbonaceous molecules aggregates (of inert matter) which nevertheless have of singular development possibilities to potential state,
potentialities from which for example, liquid water enables actualization.

- the sudden temperature variations allow to influence actualization of the genetic patrimony of drosophila embryos, what can notably lead to some organs modifications affecting their descendants.

- although the face's reactions apparently have not vital effects, the individuals of ethnic groups very different as the Papuans and Americans have similar facial contractions when they express their sorrow. (Cf. Paul Ekman - Telling Lies).
Moreover, evolved animals as the chimpanzees are expressing their feelings.
However, an essential precision, although any physical reaction depends on muscles (contractions of glands which enable the adrenalin release for example),
the muscles cannot feel, judge…, and decide !

We could quote other facts but they will not give more credibility to our comprehension of the actualization ; we consider that this one necessitates two orders of activities : physical and transcendent.

So, in our research of the primordial causes, we beware to simplistic speechs, even if they are pronounced by brilliant minds :

"How enjoyment makes us redden ... So, enjoyment gives a more lively and bright color , because it opens the heart orifices and blood is flowing more quickly in all veins …", 

"How sadness makes us turn pale ... Sadness on the contrary, narrows the heart orifices and made that blood is flowing more slowly in all veins …",

" … if we see an animal that is coming towards us, its body's light which is reflected, is painting of it two images, one in each of our eyes ; and these two images make of it two other, through the optical nerves, in internal brain surface which looks its concavities ; then from there, by intervention of the minds from which these cavities are filled, these images radiate towards small gland which these minds surround, in a such way that movement which animates every point of one of the images, is going towards the same point of the gland, … ; by means of that, both images which are in brain compose only one image on gland which acting at once on soul, enables to this one to see figure of this animal." (cf. Descartes - Passions of the Soul - Articles 115, 116, 35). 

The potentialities, particularly genetic, such as we can conceive them, today, were unknown evidently, of Descartes.
It’s the same for creative entity who actualizes, has intentions, will-power, emotions, …, and recognizes herself in the I (ego, subject, spirit).
Note that nevertheless descartes had to imagine small operators, the spirits situated in the brain cavities.

And at the present time ?
Understanding is comparable ; for example, the biologists consider the genes as singular operators, imagining thus, the alcoholism's genes, homosexuality, infantile hyperactivity, … hyperactivity, …

But, again let’s repeat,
due to its only physical nature, the matter, whatever it is, cannot recognize, judge, to choose by respecting value’s references (notably durations these intervals which are not of the space), ..., cannot decide and act.
As a consequence for example, genes as alcoholism's gene are chromosomal abnormalities (non-normalities) which can lead to some particular actualizations of genetic potentialities. 

Moreover, if there were of specific genes of physical or psychic behaviors, genetic patrimony of the man should be much richer than the one of the superior animals ; let's think of our extraordinary cognitive abilities.
But it’s not so.
We know henceforth that man’s DNA and its 3 billion pairs of nitrogen bases : Adenine, Cytosine, Guanine and Thymine has only between 20000 and 25000 genes (the biologists had banked on 100000 genes, even on 150000 genes !).
Besides, human genome is in 98,4 %, identical to that of the chimpanzees (genome of Tetraodon nigroviridis, a small fish of the Southeast Asia, already has 90 % of our genes, it is true, with less base pairs : 385 millions). 

                                                                     * 

Let’s meditate more.
The genetic potentialities of the man, how do they enable behaviors so subtle, if there is not of spectacular biological complexity increase comparatively to most evolved species ?
Furthermore, how can we understand that among the genetic mutations, some enable biological modifications and others are, apparently, without effect ? 

To try to answer, it is necessary to go beyond the current scientific theories.

The geneticists, what do they teach us for example, as for the causes which lead to differentiation (to variability) of the individuals ?
According to a communication made by Axel Kahn, in a forum speaking about the racism, at Durban ( South Africa) on September 3rd, 2001 : 

"... action mode of the genes, that is the mechanism by which they influence the beings's properties, is combinatorial as words combination gives sense to the sentence or text.
But it is not number of used words that makes literary quality of a text, as well as it is not number of genes that explains range of the human potentialities …".

Certainly, mechanism which enables the beings's diversity is combinatorial and can be compared with letters combination in word, of words in sentence and of sentences in speech, nevertheless and we insist again,
it’s not the combination which gives "sense" to word, to the sentence and to speech, but interpretation of this combination, that is interpretation of the position of letters in word, of words in sentences, of sentences in speech, what is quite different !

So, with the world's comprehension which we propose (our dualism), we understand better why small genetic differences can have spectacular consequences on beings's structures, as show the physical and psychic differences between the men and chimpanzees, while, as we previously said, their genes are identical to 98,4 %.
More exactly,
knowing that electromagnetic waves are primordial vectors of the sense,
we understand better why small interferences modifications of these waves inexorably associated to DNA's components,
of interferences which depend of spatial positions and nano-distances,
enable from changing radically, genetic processes organizations with biological effects and genetic processes organizations with psychic effects.  

Inescapable interrogations re-appear then :
- what is order (nature) of faculties which enable recognition and interpretation of electromagnetic waves's characteristics, sense vectors, which are associated to DNA and ARN ?,
- what can we say about creative entity who is judging and using the four nitrogen bases : adenine, cytosine, guanine and thymine,
and who, in front of inexorable constraints and by means of combinatorial processes, must elaborate and actualize (materialize), permanently, genetic potentialities according the living conditions ?

Research of the primordial causes presupposes therefore, more than yesterday, an extreme semantic rigour and a great opening of mind,

- a semantic rigour which leads, for example, to criticism, even to negation, of much current concise expressions emitted by the scientific popularizers ; list is long, nevertheless, two are enough, for showing necessity of such a rigour :
* "Genes manage proteins synthesis".
The genes do not manage ; they are memories and vectors of processes organizations which enable proteins synthesis, what is very different.
* "Genetic abnormalities are often responsible for pathologies".
Certainly, genetic abnormalities can be causes of disturbances which affect some biological processes organizations necessary for maintaining and developping life, but they are not primordial causes.
Besides, these abnormalities are often impacts (vestiges) of very old lived experiences.

- a great opening of mind, in particular with regard to the determinism.
This one indeed, is not only the expresion of constraints, it is also inherent to potentialities actualization (materialization).
Therefore, logically, determinism cannot be dissociated of intentional processes (and vice versa) ; multiple transformations of the beings and their behaviors give evidence of it. 
Let’s consider for example, social insects and their genetical determinsm,
* although they have of the limited knowledges and of small decision capacities, ants cultivate mushrooms, are breeding aphides, even are altruists,
* the queen of a swarm makes some of her eggs non perceptible so that they are not destroyed,
* in communities of bees, there are sacrificial behaviors ; some bees are pricking themselves and die, so that others survive.

Regrettably, at beginning of this third millennium, for the philosophers and theologians, the intentional processes are man's apanage.
As for activities of transcendent order necessitated by these processes, they are plainly ignored.
And however, who can ignore the ceaseless understandings, the recognitions, the choices, the anticipations, …, necessary to life's dynamics ! 

Let's therefore reject firmly,
and the monism which affects world's comprehension,
and taboo that hits transcendent order.
Let's tear to pieces, the weaved insidious veil and constantly maintained by temples's guards of the science, of the philosophy and theology, which masks primordial causes of the phenomena,
this insidious veil that leaves wide-open doors to upholders of the atheistic materialism.

The modern comprehension of the world, of the life's sense and of the man’s nobility, presupposes powerful knowledges with logics integrating transcendent order.
Few physicists and biologists recognize it.
As for the philosophers and theologians ?!
