摘要: Abstract Living beings have been classically described as autopoietic machines: chemical systems, which maintain a reproducible steady state by producing their components and boundaries. On the other hand, very simple micelles produced in laboratory. They consist able to catalyse production of own surfactants. However is clear that these systems are unable evolve. In this way, cannot be associated living organisms, always linked evolutionary relationships. Here I claim class conserve molecular information, feature denoted term semiopoiesis. By defining information products, semiopoietic control interaction with medium and, being convey beneficial maintenance organization offspring, can evolve natural selection. Information specific or order assumed among set possible states orders. Thus, ordered, such sequence nucleotides nucleic acids amino proteins. However, not limited copolymers. The atoms small organic compounds may also present diverse orders, giving rise isomers. Different isomers distinct physical properties biophysical-chemical an compound determined its composition i.e. positions posited. This conserved during reactions catalysed selective organocatalysts. organocatalysts appear plausible candidates primitive hosts for genetic before emergence based biopolymers. bases putative organocatalysts-based evolution discussed. Finally, argue organocatalytic designed produce programmable materials, artificial photosynthesis, self-building materials life relevant industrial impact.
