Vocal Variability of Chaffinch Song (Fringilla coelebs L.) as a Condition of Cultural Evolution in Local Populations

There are such characteristics of a matter of the nature, as variability and stability (tradition, norm). Probably, these opposites process as if other qualities of different forms of energy also create “movement ” development. Thus the given properties of a matter of the nature can be con-sidered at different levels of its organization.
