The present paper makes a contribution to the study of the multidimensional variational network of the human gerontogenesis (G. Acălugăritei, 1993-1995). In this respect was rendered evident the variation of the multiple regression coefficient (R) in relation to four sets of variables, as follows: a set of fundamental variables, a set of variational variables (variation ranks of the R), a set of reference variables (R, aging, blood pressure, sex and ABO genetic system) and a set of relational variables (relations).

This research contributes to the study of multidimensional variational network of the human gerontogenesis (G. Acĭlugăritei, 1993-1995).

The main general criterion used is the degree and type of phylogenetic differentiation. In relation to this criterion, criteria are given for the classification of the fundamental types of ontogenetic reproduction and for the classification of the types of ontogenetic generation cycles.

The characteristics of individual development differ in terms of its processes, stages, types and orders. Ontogenesis and ageing of the organism represent the principal processes of individual development.
