The paper discusses how did a human logic through the biological evolution arise. In order to understand, why and how did logic rules and their applicability to the nature cognition arise, it is reasonable to construct the theory of evolutionary origin of human logic. Such a theory could include the mathematical models of the most important "intellectual inventions" of biological evolution by means of which animals "cognize" the natural regularities as well as the models of evolutionary transitions between intellectual inventions of different levels.
