ABSTRACT
Evolution of reproductive units or organisms assumes two processes. One is the generation of variations, and the other is the fixation of variations thus generated. Tracing the evolutionary sequence of biologically reproductive units first requires an identification of those basic characteristics that are applicable to any stage of evolution. Genotypic adaptability exhibits itself in the evolutionary enhancement of reproductive fidelity through the genealogical sequence of surviving organisms because of the involvement of material flow equilibration there. Evolution viewed from the legitimate law of motion of the one-to-many mapping type lets the endogenous enhancement of reproductive fidelity be the most fundamental process. Phenotypic adaptability serves as a premise for the evolution of the genotype. Evolution is an example of a physical process that operates in the mode of final causality. Natural selection as the process communicating conservedness applies to the spatiotemporally localized class of individual organisms in which the internal communication for conservedness actually materializes.
