Within the framework of complex systems, the term "development" has a specific meaning: denotes a spontaneous dynamic process of self-creation, under the catalytic influence of the environment, where structures of increasing complexity are successively created according to a bottom-up recursive process (e.g. in the living systems: proteins ® tissues ® organs). The "development" saves information, as in each developmental phase different types of the system's structural units derive from the differentiation of already created types (basic type ® differentiation ® composition of the differentiated types). The development of the living organisms is referred to as "embryogeny".
