A pre-biotic speciative decision operator

This work proposes a fundamentally new way to understand speciation by moving the problem entirely upstream of biology. Instead of treating speciation as a consequence of reproduction, genetics, natural selection, or chance, we show that irreversible differentiation can arise before life itself, as a purely geometric phenomenon in the space of possible states.We introduce the idea that early systems evolve within a landscape shaped by a field of ontological indefiniteness, which determines how easily a state can persist or dissolve. This landscape induces strong directional constraints: some directions of evolution remain accessible, while others progressively close. Speciation occurs when this admissible space fragments into disconnected regions, making certain evolutionary paths impossible to return to.Crucially, this process involves no agent, no optimization, no selection mechanism, and no probabilistic choice. The “decision” to speciate is not a choice but an irreversible geometric locking of possibilities. We define a universal, dimensionless quantity—the pre-biotic speciative decision operator—that measures how strongly and how rapidly this closure of possibilities occurs across the system. When this quantity exceeds a critical threshold, speciation becomes unavoidable.This framework reinterprets speciation as a phase transition in the space of possible forms, driven by geometry rather than biology. It provides a unified, pre-biotic explanation for the emergence of distinct forms and opens new perspectives on the origin of life, morphogenesis, and the emergence of structured complexity in nature.
