In 1513, 500 years ago, Leonardo da Vinci wrote: “Before you take another step, will perform experiments, because my purpose is to expose first experience and then, by reasoning show why such experience is designed to operate in precisely this way it is. This is the true rule to be followed by those who reflect on the phenomena of nature. “

In 1859, 155 years ago, Charles Darwin wrote in his book “ The Origin of species”: “I must conclude that probably all organic beings who have lived on this earth have descended from someone primordial form. “

Darwin proposed the existence of a single universal ancestor although he did not specify whether it was a unicellular or multicellular organism.

Embryological studies later showed that all embryos follow a common pattern in the early stages that correspond, step by step, with the evolution of the species (from annelid, to fish, to amphibian, to reptile to mammal).

Moreover deciphering the genetic code to the end of the twentieth century proved its universality and this fact relates to including all forms of life.

Therefore Leonardo, Darwin, embryological studies and deciphering the genetic code lead us to a common origin of all living beings, who subsequently would diversify.

Now is necessary to stop at a very early point of diversification. In a moment we have two types of cells: ones that are able to use solar or geothermal energy to produce organic matter and other organic matter that would use this for development. The first constitute the ancestor of plant cells and the second the ancestor of animal cells.

Both have a central porphyrin ring that encloses a magnesium atom (vegetal chlorophyll) or an iron atom (animal hemoglobin) and this links them with a common ancestor that diverged.

It is logical to think that the plant cell must be the first stage of diversification because it is the producer of nutrients needed by animal cells. This opens a promising line of basic research for testing the following hypothesis: “If the vegetal cells are prior to animal cells, and therefore these are dependent on those, is likely that influencing vegetal cells, on animal cells by providing nutrients or energy constituents, and providing them pronutrients. If plant nutrients cooperate with the cytoplasm of animal cells, it is probable that plant pronutrients work with genetic material and allow the emergence of new characteristics by activating certain existing switches in the genetic code of animal cells that influence inactive gene expression to date.

Demonstration of this hypothesis would open the application of pronutrients of plant origin, to the expression control of animal cells, and constitute an important source of progress in veterinary science while would be necessary reflection on the need to focus research for second genesis in a double way, one for plant cells and one for animal cells in a manner that could consummate the necessary interrelation between both gene expression.

Leonardo da Vinci’s ideas delved into Cosmography of Ptolemy and he considered the macrocosm that we can observe with our eyes has influence in the organization of other microcosm. So the four elements that constitute nature (air, water, earth and fire) would correspond the four humors that constitute human nature, or rivers of the Earth would correspond veins of the human body.

This idea of ​​macrocosm and microcosm correlation between from Leonardo, we can apply it to the influence of plant populations in animal populations: “A large variety of plants in the macrocosm of the mountains or the jungles corresponds to a variety of animals that live in these macrocosm as a diversification of  microscopic plants primitive cells in water will correspond to great diversification of primitive microscopic animal cells, and a great diversity of plant primitive multicellular will correspond to great diversification of primitive multicellular animals “
