ProtokoIler

ProtokoIler is a term used in speculative biology and science fiction to denote a class of hypothetical primitive life-forms or proto-organisms that could have existed in the transition from chemistry to biology. It is not an established scientific taxon and has no direct fossil record; rather, it serves as a conceptual device for discussing early life processes.

In commonly described models, ProtokoIler entities are imagined as simple, semi-permeable compartments formed by amphiphilic molecules. They may harbor rudimentary catalytic systems and a minimal genetic-like information carrier, yet lack a fully developed cellular membrane or nucleus. Their metabolism is assumed to be basic, relying on environmental substrates and energy sources available in prebiotic settings, with growth and replication driven by templated assembly rather than a modern replication machinery.

The concept is used to explore how gradual steps from chemistry to biology might occur, including the emergence of compartmentalization, metabolism, and information storage. It helps frame debates about how early information-carriers, membranes, and metabolic networks co-evolved and why a defined genetic code may have emerged later in life’s timeline.

In educational and fictional contexts, ProtokoIler often appears as a narrative or thought-experiment device to illustrate plausible intermediates between nonliving chemistry and living systems. Related topics include abiogenesis, protobionts, lipid vesicles, and the RNA world hypothesis.
