- An analysis of research data and published data on comparable standard metabolism in invertebrates is carried out. It is shown that this parameter varies insignificantly within each family and most orders. The mean values of the comparable standard metabolism for orders are grouped around certain values. It is assumed that these values correspond to stationary states, which organisms seek to reach during the evolutionary process. A total of nine levels of stationary states have been identified. The ratio of the values of comparable standard metabolism for neighboring levels is approximately 2.25. The orders occupy ever higher stationary levels in the process of macroevolution of phyla and classes. A possible mechanism for the transition from one stationary level to another is discussed.
