Ontogenetics

Ontogenetics is a branch of biology that studies the individual development of organisms (ontogenesis). Ontogenesis includes all processes occurring in the body from the moment of formation of the zygote to the end of life.

Ontogenetics examines the patterns, mechanisms and driving forces of ontogenesis at all its stages - embryonic, post-embryonic and the period of aging. The main objectives of ontogenetics are: the study of the processes of division, differentiation and integration of cells, tissues and organs during individual development; analysis of the interaction of genotype and environmental factors that determine the course of ontogenesis; study of molecular, cellular and tissue mechanisms underlying the formation of biological structures in the process of ontogenesis.

Ontogenetics is closely related to other biological sciences - genetics, embryology, physiology, etc. Its development has important theoretical and practical significance for medicine, agriculture and other fields.

Ontogenetics is a complex science that studies the characteristics of the life cycle of an organism. It examines changes throughout life, from the beginning of the embryo to the death of a member of the species. Scientists work with the stages of ontogenesis of various creatures, from viruses to humans. The founder of the direction is Karl Ernst von Baer. His teaching states that ontogeny repeats the evolution of ancestors, but on a smaller scale. The concept is based on the theory of Charles Darwin. Ontology and, accordingly, ontogeny were laid down by zoologists, michurinists, biologists-morphologists, from new branches of science - population genetics, interdisciplinary developmental sciences, integrative biology. Together with the development of medicine according to evolutionary theory, the idea begins its development as a new branch of biology and sounds like the genetics of individual development. With gradual penetration into related areas of biology, ontography is expanding its sphere of influence. Later
