THE BASIC FUNCTIONS OF SOUND SIGNALS IN MAMMALS

Abstract

All the diversity of sound signals by mammals is subordinated two basic functions: function implementation of the populations of genotype and function realization of the ecological niche of species populations. The basic functions have resulted from some relatively independent trends in the evolution of sound signals as those developing the genetically determined structure and the ecologically determined functions. A relative independence of the above trends in the sound signal evolution supports variation.
