PL‐5information about x contained in y is defined ascan be used incomparison of primordial and advanced objects of both classes. However, the content of xand y must satisfy the requirements of scope selected.In this report, the biological objects of different hierarchical and evolutionary status willbe shown to be characterized by variable contribution of complexity of different types. Inthe course of the individual development, the KCS’ complexity remains nearly equal fordifferent states of chromatin and especially for chromatins of the parent and daughter germcells. At the same time the context‐dependent complexity is variable because the differentstages of development of biological object are represented by the different sets ofobservables; accordingly, the meaning content of term “context” varies too. The contextdependentcomplexity has a tendency to grow in the course of the individual developmentof object.The evolutionary primordial objects possess the lowest KCS’ complexity in comparisonwith more advanced ones. However, their context‐dependent complexity (complexity ofexternal relations) can be of relatively high value because the list and length of externalstrings increase to support the reproduction of primordial objects of this class. In the case ofviruses, e.g., even the operational moiety of chromatin (host structures) acquires the statusof external in relation to that of primordial object.These observations can be generalized in the implication that objects of biological worlddemonstrate a tendency to compensate the deficit of KCS’ complexity by means of increaseof context‐dependent complexity. Approximating this tendency in the scope of pre‐biology,one can suggest that at least some of problems of transition to objects with biological levelof complexity were settled through the substitution of one type complexity with another.Nevertheless, a question remains: if the highest values of context‐dependent complexity inpre‐biological systems can be sufficient to ensure the total complexity comparable with thatof primordial biological object or of intermediate objects at period of transition fromchemical evolution to biological one.References[1].
