If we observe the development of any embryo we will see an accelerated film evolution of life, starting with a single cell, continues with the association of several undifferentiated cells, before moving on to the stage of differentiation and its consequence, the emergence tissues and organs of the future adult. Millions of years of evolution condensed in a few days or months depending on the species observed.

During the viewing of this whole film will never observe the arrival of new genetic material, ie primitive genetic material of cells is equal to all the cells of different organs of the adult animal.

Overlaying the film several embryos: an embryonic annelid, another of fish, other of amphibian, other of reptile and finally another one of mammal, we could see the end of a movie can be adjusted with the beginning of a period movie following embryo in the evolutionary chain.

We could think that nature has added genetic material but could also consider that the genetic material was present in the primitive cells although in each stage is expressed only up to a point of reading.

Thus, the observation of this accelerated evolution film through the study of embryonic development we can reach the following assumptions:

(1) The primitive cells of any embryo contains all the genetic material in all cells of the adult.

The differentiation of cells is produced by the "off" programmed by their genes and not by a loss of genetic material.

(2) The primitive cells of any embryo contains all the material of the primitive cell embryos from previous scales and, given the improbable addition of new genetic material at specific locations throughout suggests that also contains genetic material of cells primitive of embryos from subsequent scales.

Reading level would be in this case by the "on" programmed from their genes from one scale to the next and not the incorporation of genetic material.

(3) Therefore there are mechanisms for "off" and "on" reading of specific genetic material that can be based on a pre-programming of genetic information system itself or by the influence of substances in food.

(4) It is probable that the "off" reading of a part of the genetic material can be accomplished by pre-programming style "after 200 replicas let working"

(5) Certain plant nutrients may be biochemical signals "on" switches reading genetic information existing in a state of lethargy.

(6) These new forms of life emerged from the ignition of dormant genetic material would be selected based on the natural environmental conditions of the moment.

In this way the primitive genetic basis, programmed off mechanisms for differentiation, ignition mechanisms in response to biochemical signals of plant nutrients for new expressions of animal genetic material and natural selection work together in the appearance and development of new forms of animal life.

Based on these six postulates, we are able to expose,   in the second part of this article, a first hypothesis formulation of pronutrients as part of the theory of evolution.
