A theoretical biology framework for exploring the behavioral extensibility of reaction systems
摘要
During evolution, some living systems grow more complex. They develop new functions and new structures: flying and wings, digestion and digestive systems, swimming and fins, etc. Due to natural selection, this increase in complexity must be operated while keeping livelihood, i.e., the new structures and functions are added while maintaining the original behavior. In this work, we continue the effort of representing the phenomenon of structural and behavioral extension in abstract discrete dynamical systems in order to elucidate some big-picture tendencies. We choose reaction systems as the formal tool, and propose a translation into this new language of the extensibility framework we developed previously. We argue that using reaction systems makes definitions lighter and therefore should allow for better insights from future exhaustive exploration of the extension space.
