On the definition of a self-sustaining chemical reaction system and its role in heredity.

摘要: The ability to self-sustain is one of the essential properties life. However, a consistent and satisfying definition self-sustainability still missing. Currently, refers either “no-intervention by higher entity” or “regeneration all system’s components”. How connect with heredity, another life, problem, as they are often considered be independent each other. Last but not least, current definitions failed provide practical method empirically discern whether chemical system self-sustaining not. Here I propose self-sustainability. It takes into account reaction network itself external environment which simplified continuous-flow stirred tank reactor. One distinct property systems that can only proceed if molecular triggers (or called, seeds) present initially. able establish whole system, indicating carry preliminary heredity system. Consequently, life large group fires (and other dissipative systems) distinguished. Besides, general various real-life examples discussed here together indicate uncommon. proposed naturally connects heredity. As this involves reactor, it gives simple way test Moreover, guidance on how construct detect such in real biology chemistry. This article was reviewed Wentao Ma David Baum.
