| Popis: | There are many perspectives through which biologists can study a particular living system. As a result, models of biological systems are often quite different from one another, both in form and size. Thus, in order for us to generate reliable knowledge of a particular system, we need to understand how the models that represent it are related. In previous work, we constructed a general model comparison framework to compare models representing any physical system. Here, we develop an alternative methodology that focuses on a fundamental feature of living systems, namely self-organisation. We employ a graph theoretic formalism which captures self-organising processes as cycles within particular kinds of graphs: process-enablement graphs. We then build the mathematical tools needed to compare biological models and their corresponding descriptions of self-organisation in a consistent and rigorous manner. We apply our formalism to a range of classical theories of life to show how they are similar and where they differ. We also investigate examples of putatively abiotic systems which nonetheless still realise primitive forms of self-organisation. While our current framework does not demarcate living systems from nonliving ones, it does allow us to better study the grey area surrounding life's edge. Comment: 31 pages, 11 figures, 1 table |
