Notes added in proof of an earlier paper on an empirical "law" of information growth in evolution, and in response to questions raised therein.Keywords: Information growth, system stability, evolution A recent paper [1] in this journal presented evidence for a systematic growth of information in the history of the cosmos, of the life on earth, and of the technology developed there. This evidence is empirical, guided by a cybernetic model of evolution that has been successfully applied to several other physical and sociological phenomena [2]. In this case the scale of the data offered is so great, and because the relation between information and entropy is so close [3], the question was raised of the relation being an unrecognized aspect of the second law of thermodynamics. In particular it was asked "whether a theoretical foundation can be found for this phenomenology . . . ."That paper also points out that: "From the Second Law of Thermodynamics, we know that the increase of entropy is a consequence of the dynamics of system change, not their source, although we often use it as such. However, 'Processes that generate order are in no sense driven by the growth of entropy [4].' The relation between entropy and information means that this is true of the latter as well as the former." This implies that indirect mechanisms must be involved in the information development described.In this regard, Schneider and Kay [5] discuss the behavior of systems in dynamic equilibrium under a set of external fluxes and forces. When these influences change, the systems react in ways to resist being moved from their equilibrium. If a threshold is crossed they may develop a new state to oppose further movement from equilibrium. A common example is the Benard cell, a container of fluid heated from below. Heat rises through the liquid by conduction, i.e., molecular collisions. If the temperature gradient and heat flux increase too much the cell suddenly displays an emergent, coherent
