The Morphogenesis of Multicellularity: 1 From Cell to System: The Emergence of Organismal Potential

When a living cell divides, it does not simply produce more of itself. It produces a field of relation—a topology of potentials that can be aligned, differentiated, and stabilised into a new kind of coherence. What we call “multicellularity” is not a matter of aggregation but of collective morphogenesis: a phase transition in which cells cease to be autonomous loci of survival and become semiotic participants in a shared reflex.

In relational terms, each cell is an instance of living potential, an event of metabolic construal. It interprets and enacts the field of possibilities available to it—chemical gradients, nutrient flows, energy differentials. Yet once neighbouring cells begin to align these construals, the local field itself changes. Each cell’s perspective becomes part of a larger perspectival topology, a field of coordinated meaning.

At this moment, a new level of potential comes into existence—the organism. The organism is not an object that contains cells; it is the relational system by which cellular potentials are synchronised into a coherent semiotic pattern. Cell membranes cease to mark the outer limits of being; they become internal boundaries within a higher-order field of exchange.

In evolutionary accounts, this transition is often explained as the product of cooperation, division of labour, or selective advantage. But these are descriptions of the consequences, not the conditions. The condition is morphogenetic: the stabilisation of a shared topology of potential across many local construals. The organism comes into being when alignment itself becomes the basis of persistence.

What emerges, then, is not a hierarchy but a reflexive system—a living relational grammar capable of saying, through every act of cellular differentiation, I am this, and not that. The organismal form is a semiotic unity, sustained not by control but by continual negotiation of meaning among its constituent fields.

The cell, in joining others, does not lose its individuality; it re-individuates within a new domain of potential. Multicellularity is thus the first great experiment in relational recursion, the cosmos learning how to actualise itself through internal dialogue.
