    No, because the same criterion is specific to different species. For a more accurate and reliable definition, it is necessary to use several criteria: physiological, biochemical, environmental, and geographical.

    Physiological criterion-it is based on the similarity of life processes in individuals of each species, especially reproduction.

    The morphological criterion reflects the set of features of the external structure.

    Biochemical criterion-reflects the characteristic chemical composition of the body and metabolism.

    Genetic criterion-characterized by a certain set of chromosomes that are similar in size, shape, and composition.
