Phylogeny

Phylogenesis is the process of historical development of living nature and individual groups of its constituent organisms. The scientific basis for ideas about phylogenesis is the evolutionary doctrine created by Charles Darwin.

The branch of biology that studies phylogeny and its patterns is called phylogenetics. He studies the origin of modern forms from ancestral ancestors, as well as the reasons determining the course of their evolution, the laws of this evolution, etc.

Schematically, the phylogeny of animals and plants is usually represented in the form of a so-called family tree. Its trunk corresponds to the initial forms of life, and its branches correspond to all subsequent numerous and increasingly complex forms.

Phylogenesis should be considered in unity and interdependence with the development of an individual, that is, ontogenesis.

The phylogenetic period is one of the most interesting and fascinating stages in the evolution of life on Earth. This phenomenon describes the process of formation of common characteristics in living organisms based on genetic continuity. Phylogenic processes lead to the emergence of new species, groups and families of living organisms due to gradual adaptation to changing environmental conditions.

During the phylogenetic period, changes occur in the structure and function of living organisms, which are the result of a combination of inherited characteristics from previous generations. At first
