geneion

Geneion is a theoretical concept representing a fundamental unit of genetic information transmission. It is envisioned as a self-replicating entity that carries genetic material, enabling the propagation of traits from one generation to the next. Unlike genes, which are typically understood as segments of DNA or RNA that code for proteins, geneions are considered to be more abstract and potentially capable of existing in various forms. The idea of a geneion arises from speculative evolutionary biology and the study of the origins of life. It proposes a primitive mechanism for inheritance that predates the complex molecular machinery of modern cells.

The theoretical framework suggests that geneions would possess the essential properties of life: replication, variation, and selection. Their ability to replicate would ensure their continuity, while inherent variation would provide the raw material for evolutionary change. Natural selection would then act upon these variations, favoring geneions that are more successful at replication and survival in their given environment. This concept is particularly relevant when considering hypothetical scenarios of abiogenesis, the process by which life arises from non-living matter. Geneions offer a potential explanation for how replicating informational systems could have emerged and evolved before the advent of DNA, RNA, and cellular structures.

While geneion remains a theoretical construct, it serves as a useful tool for exploring fundamental questions about heredity and evolution. It encourages researchers to think beyond the established biological paradigms and consider alternative pathways for the development of life. The concept is not directly observable or experimentally verifiable in the current biological landscape but stimulates thought experiments and theoretical modeling in the field of origins of life research and evolutionary theory.
