The writing appeared for the first time, it is said to us, on clay tablets about 5000 years ago, in oldest Mesopotamia, in towns of Uruk and Kish.
Whatever epoch has been 6, 7, 8000 years, whatever place has been, in Mesopotamia, in Indus valley, in Egypt, this written formalization (this written representation) of concepts, this particular capacity is mysterious.
What can we say of it ?

Certainly, we can believe that appearance of the writing has depended on commercial activities development ; nevertheless, was this fact a primordial cause ?
No.
The needs to exchange more easily goods have been objective causes (visible causes), secondary of the philosophic view point.
Indeed, if the concerned men had not had the adequate abstraction capacities (the brain potentialities), never they would have been able to write and count.

Let's us remember too, that other civilizations that evolved in Meso-America, civilizations descending from very old Indo-European migrations (between 80.000 and 20.000 years before J.C ?) was able to count, for example by means of knots on ropes. 

It’s the same for language ; under all its forms, this one express actualization (materialization to become realities) of potential means which enable sense's diffusion,
potential means (brain potentialities) which have been developed constantly during human history, and are still developed.

In other words, the language, the writing and possibility to count are depending on innate potentialities and from transcendent faculties which enable meaning, by various manners.

We are thus, far enough from the Engels's understanding, expressed in his preparatory notes to the Anti-Dühring :
"If, for example, in our countries the mathematical axioms are perfectly evident for an eight-year-old child, without the help of a master, it is only the consequence of the accumulated heredity".

Regrettably today, it is discussed hardly, of the "nature" ("order") of such faculties and not at all, of the timeless domain where are the potentialities (where are the potential states).
And however, to light of recent scientific discoveries, one can show easily the "realism" (existence) of universal value’s references, of unchanging processes , of immutable structural forms, of psychic forces, of anticipations, …, which are into the abstraction’s mysterious domain.

It is true, it’s a revolutionary conceptualization which necessitates from containing the scientifical formalizations in their validity domain notably so as to integrate the transcendent order in world’s understanding.

At the beginning of the third millennium, the one who is in a research of the primordial causes, indeed more than yesterday, can recognize links between what is "perceptible" and what is "potential",
that is to say between the physical activities (notably those which lead to physical reality's states) and the creation activities of transcendent order, particularly expressed by the genetic potentialities.
The invariant and the evolutive, the eternal and the historical, the real and the virtual, characterize world !
Plato and Plotinus would not contradict us.

F. Jacob, saw in polyvalence of the living entities as the organs, the "do-it-yourself" of the evolution and spoke about Nature as about an operator able to create the variety by combinations in an unlimited way, of same pieces and same fragments ". (Cf. The game of the possibilities - 1991).

But an operator, when he wants to organize, must recognize, judge, choose, anticipate, …, decide and act, and thus, must be outside the perceptible reality and implicated in it.
Of this fact the potentialities actualization (their materialization to become realities) does not result from a do-it-yourself ; think to ceaseless creation activities, of physical order and of transcendent order, that are taking place in the cells. Without such activities, notably to obtain novelties by means of genetic potentialities, there would not be life and evolution of species.
We are therefore far from the commun Darwinism recognized and taught of an almost dogmatic manner, by the paleontologists.

Remember the theories developed after Lucy's discovery in 1974, which were saying us that climatic modifications which are appeared in Africa, about eight million years ago,
and the "bipedalism",
have been the prime causes to origin of the man.
We must be rigorous in phenomena's analysis ; this phylum as the others, the comportments, all phenomena are resulting of specific potentialities actualizations (materializations). 

To rise to trees for example, it’s necessary to have, beforehand, the genetic, physical and psychic adequate potentialities, notably those which enable vertical position,
the environmental constraints being only moment's causes.

More generally, potentialities are actualized (materialized),
and for necessary individualizations,
and according to environment.

In reality, species evolution shows long stability periods interrupted by fast changes,
facts evidently, which have to be analyzed by taking into consideration inert matter's dynamics. 

That is why,
knowing that phase transitions and periods halvings are inexorable facts observed during complexity increase of physical phenomena (evolutions of chaotic type with periods halvings are observed until most elementary level of the inert matter),
we recognize to individuals of evolved species, a "genetic potential" not only that is characteristic of their level of complexity but also, which can increase by means of ceaseless creative activities, of physical order and of transcendent order, until, sometimes, critical thresholds inducing remarkable structural jumps.
Sexual reproduction is typical example.

Observe that this understanding agrees with theory of the "Punctuated equilibria" emitted by Eldredge and Gould.
It also helps to understand better why individuals of remarkable species are "opened" to more complexity although they are composed of biological entities common to all beings.
More complexity but,
what is primordial intention ?,
what is imperative necessity ?
