Abstract

The hypothesis “life on the edge of chaos” results from the stability of RBN, but living objects are not random; their structure and function are selected just for stability by Darwinian natural selection. The order of a crystal emerges spontaneously. The networks modeling living objects can be simultaneously ordered and chaotic on a similar level. They use chaotic parameters of RBNs. It is another edge of chaos. Definitions of artifacts are subjective and imprecise; problem should be described in other perspective. Basic properties of natural life result from its spontaneity, which suggests a limit of using artificial life in investigations of life
