Man is a biosocial being, because his life takes place in a system of biological and social conditions.
The unity of man with other living organisms on Earth is confirmed at the cellular level, which was proved with the invention of the light microscope.
As a biological species, man belongs to the Kingdom of Animals.
At the cellular level, this is indicated by the similarity of the structure, chemical composition and vital activity of the cells of the human body with the cells of animals.
Human cells also have a formed nucleus, a general structure plan, and heterotrophic nutrition.
At the organismic level, the similarity between humans and vertebrates is confirmed by the general plan of the structure of organs and organ systems, the similarity of vital processes.
At the same time, man is distinguished from all other animals by the presence of consciousness and abstract thinking, a well-developed brain, speech and other features.
The external and internal structure of the human body, the features of vital processes allow us to determine its place in the kingdom of Animals.
So, according to the presence of a spine, a person should be classified as a Chordate.
Intrauterine development and the presence of mammary glands for feeding babies indicates that a person is a member of the Mammals class.
By the similarity of the structure and features of human life, they are classified as primates.
Modern man belongs to the family of the Hominids, the genus Man, the species Homo sapiens.
