Abstract :
What is unique to biodynamics in vivo or dynamics leading to the emergence of biological organizations is a frozen aggregate of degrees of freedom in motion that can change its constituent members in time. Association and dissociation of degrees of freedom in the frozen aggregate is information-generative, in the sense that their realization proceeds in a contingent manner, with no unique pattern being predetermined. In particular, dissociation of some of the degrees of freedom from the parental aggregate becomes information-generative when the dissociative interaction initiated by thermal agitation originating in the ambient takes significantly longer time than the interval of the inverse thermal frequency. For instance, ATP hydrolysis with the help of myosin following the preceding association of an ATP molecule with the myosin happens to be a case of such a dissociative interaction, in which the duration of the interaction is far greater than the inverse of thermal frequency. One dominant mode of biodynamics in vivo is to effectively materialize a heat engine by preparing a local region with a temperature lower than that of the surroundings, thereby letting the duration time of the dissociative interaction be far greater than the inverse of thermal frequency. Evolutionary emergence of most primitive biological organizations would coincide with a de novo appearance of a heat engine that could hold thermal agitations from the surroundings locally there and could act upon the latter accordingly.
