Understanding how biological homochirality emerged remains a challenge for the researchers interested in the origin of life. During the last decades, stable nonracemic steady states of nonequilibrium chemical systems have been discussed as a possible response to this problem. In line with this framework, a description of recycled systems was provided in(More)
Autocatalysis is a fundamental concept, used in a wide range of domains. From its most general definition, that is, a process in which a chemical compound is able to catalyze its own formation, several different systems can be described. We detail the different categories of autocatalyses, and compare them on the basis of their mechanistic, kinetic, and(More)
The question of the onset of the homochirality on prebiotic Earth still remains a fundamental question in the quest for the origin of life. Recent works in this field introduce the concept of recycling, rather than the traditional open-flow system described by Frank. This approach has been criticized by Blackmond et al. They claimed that such systems are(More)
Living organisms perform and control complex behaviors by using webs of chemical reactions organized in precise networks. Understanding how lifelike behaviors emerge from such complex chemical systems is a challenge for artificial life scientists. An approach is to implement minimal in vitro systems, possessing the characteristic dynamic properties of(More)
The mechanisms for explaining how a stable asymmetric chemical system can be formed from a symmetric chemical system, in the absence of any asymmetric influence other than statistical fluctuations, have been developed during the last decades, focusing on the non-linear kinetic aspects. Besides the absolute necessity of self-amplification processes, the(More)
