This manuscript presents an integrative theoretical framework linking ageing, evolutionary biology, and consciousness through the concept of environment–biology interaction mediated by structured radiation fields. Current biological models explain ageing primarily through intrinsic mechanisms such as genomic instability, oxidative stress, and epigenetic drift. Evolution is similarly understood through natural selection acting on random variation. Consciousness, in turn, is generally treated as an emergent property of neural activity confined to the lifespan of the organism. While each of these domains has advanced independently, a unifying framework remains lacking. This work proposes that biological systems exist in continuous interaction with a structured environmental radiation field, comprising spectral and cosmic components. It is hypothesised that this interaction contributes not only to known processes such as photosynthesis and vitamin D synthesis, but also to broader, currently uncharacterised mechanisms involved in maintaining genomic stability and biological integrity. Ageing is conceptualised as a progressive decoupling from these sustaining environmental inputs. Extending this framework, the manuscript explores the possibility that variation in environmental radiation may influence evolutionary trajectories by modulating mutation patterns and repair processes, thereby introducing directionality within the constraints of natural selection. At the level of consciousness, the paper proposes an information-based model in which conscious states undergo processes of integration, fragmentation, and recombination. It is hypothesised that, following loss of neural integration at death, informational structures may fragment and, under specific conditions, interact with developing biological systems. Neuroendocrine pathways, particularly involving the hypothalamus, are explored as potential biological interfaces for such interaction. The manuscript synthesises concepts from neuroscience, developmental biology, evolutionary biology, and biophysics to propose a unified, testable framework. While speculative, the hypothesis generates multiple avenues for empirical investigation, including experimental models of environmental decoupling, analysis of genomic stability under altered radiation exposure, and study of developmental and neuroendocrine correlates in early-life memory phenomena. This work is presented as a conceptual contribution aimed at stimulating interdisciplinary research and expanding current understanding of biological systems as open, information-responsive entities.
