چکیده انگلیسی
Self-ordering proto-replicators provide an abstract, simulation based investigation of a possible intermediary step in the development of informational replicators. They involve the dynamic self-ordering of generalised subunits of at least two types into coherent and mobile structures, and do not require the pre-existence of templates, replicators or functional catalysts. The following discussion naturally extends this approach to include pairs of such systems linked via a probabilistic, inter-system movement of structures. Initially for two specific forms of self-ordering proto-replicator, various types of probabilistic movement were studied, both with and without a simple model of a primitive membrane. Then for a specific probabilistic movement, which was again considered with and without membranes, different pairings of twelve forms of self-ordering proto-replicators were studied. The results show that the systems exhibited a form of passive competition for subunits and that this produced a new level of multi-system self-ordering that depended upon the relative self-ordering capabilities of the individual systems. This effect was also found to be significantly more pronounced for those systems that included the primitive membranes. The implications for the origins of life were then considered.
