DESCRIPTION:Life is a chemical reaction. Or, more precisely, life is a functionally closed and self-sustaining\nchemical reaction network. In other words, living systems produce their own components, in\nsuch a way as to maintain and regulate the chemical reaction network that produced them.\nDuring the 1970s, several researchers independently developed formal models of a minimal\nliving system based on the above definition. However, most of these models do not explain\nhow these systems could have emerged spontaneously from basic chemistry. They provide\ninsights into the organization of life, but not necessarily its origin.\nNow, a new mathematical framework, based on the original notion of autocatalytic sets, is\nable to shed more light on both of these aspects. Autocatalytic sets capture the functionally\nclosed and self-sustaining properties of life in a formal way, and detailed studies have shown\nhow such sets emerge spontaneously, and can then evolve further, in simple models of\nchemical reaction networks. Furthermore, this new framework has been applied directly and\nsuccessfully to real chemical and biological networks. Thus, the autocatalytic sets framework\nprovides a useful and formal tool for studying and understanding both the origin and\norganization of life.\nIn this talk, I will give a non-technical overview of the background, concepts, and main results\nof the formal framework, and how it can perhaps be generalized beyond chemistry and the\norigin of life to entire living systems, ecological networks, and possibly even social systems\nlike the economy.
