Conventional framing
Space and time are typically treated as neutral coordinates within which biological processes occur. Spatial organisation is described in terms of location, structure, or “levels,” while temporal organisation is described in terms of sequence, duration, or stages. In this view, space and time provide the background framework for biological activity but are not themselves considered part of what requires explanation.
APS reframing
In APS, space and time are not treated as external containers or independent dimensions, but as organised features of living systems. Spatiotemporal organisation refers to the structured distribution and coordination of activity across space and time through which systems sustain their own viability.
Spatial organisation is not merely positional but consists in the structured differentiation of regions, boundaries, and relations—such as membranes, gradients, and patterns of coupling—that matter for the system’s activity. Temporal organisation is not merely sequential but consists in the continuity and transformation of activity through which systems persist, regulate, and adapt.
These spatial and temporal relations are not independent. They are integrated in process. Biological processes are inherently spatiotemporal: they are distributed across domains and unfold through time as coordinated activity. The organisation of space and time is therefore not an additional feature of biological systems, but intrinsic to their mode of existence as dynamically maintained processes.
Spatiotemporal organisation is closely related to scale. In APS, scale does not refer to hierarchical levels, but to the distributed extent of processes across spatial and temporal domains. The coordination of activity across these domains is essential to maintaining viability.
Biological systems do not passively occupy space and time. They actively structure spatial and temporal relations in ways that sustain their organisation. In this sense, spatiotemporal organisation is an expression of biological agency and a condition of biological normativity: it determines how processes are arranged and coordinated so as to contribute to persistence.
Key Point
Spatiotemporal organisation is not the background of biological activity but part of its organisation: the structured distribution and coordination of processes across space and time through which living systems maintain viability.
