Correlative Variation of the Essential Amino Acids

Under the expression correlative variation Charles Darwin understands that the whole organization is internally connected during growth and development, and when weak variations occur in one part and are cumulated by natural selection, the other parts are modified. Modifications in the structure recognized by taxonomists for a very important, can depend solely on the laws of variation and correlation [1]. For example, Phyto enosis [2] has at least three fundamental properties: first, the correlative variation in the values of parameters in time and space; second, the correlation depends on the genotypic properties of the plant species; third, the variation is due to phenotypic properties, as well as the cycles of solar activity [3], the rotation of the moon around the Earth and our planet around itself [4].
