The arrows within the cells represent the concepts of dependence and of competition. The arrows between the cells represent many stages and cells in transition. In this diagram, cell A represents the toti-potential fer- tilized ovum. Immediately following fertilization, the mech- anisms for reduplication and for special functions become activated, and this is indicated by the arrows from the cell food to the functions. Both mechanisms have increased in size. FERTILIZED OVUM D-MECHANISM FOR CELLULAR REDUPLICATION O-MECHANISM FOR SPECIAL FUNCTIONS !S-C ELL-FOOD Figure 2. The first special system to become functional is the one repre- sented by the circle labeled F. As the products of its reactions become quantitatively significant, some of these metabolites are used to catalyze and initiate the next sequence of reactions, as depicted by the arrows labeled 7 and 2. The ultimate charac- teristics of the differentiated cells are predetermined by the particular system of reactions which is nurtured in the first few generations of cells. If, in a given cell, the H function is the first one to be stimulated, as indicated by arrow 7, the subsequent course of events in descendants of this cell will follow the upper 683
