The unity of biological and social
Man created the work – the first basic condition for its existence. People are different from all other living creatures the ability to produce a variety of subtle movements. This ability is developed in the process of labor. To assign a material nature in a form suitable to meet their needs, to create a livelihood, a man transforms nature (prints a new species, new breeds of animals, extract minerals and so on. D.). Acting on the nature of the functions by means of the sense organs, the nervous system and skeletal muscle, man changes his own nature, structure and functions of the organism, especially the sense organs, the nervous system and skeletal muscles.
The main qualitative difference between the human body from the body of the animal stands out clearly in the study of changes in the phylogeny of the functions and structure of the body of the ancient ape (more in the article “The ancestors of man”).
In the transition from animal to man, we meet with the new laws that are specific to humans. Man can not be regarded only as a pet, as the body structure, function of his body, his behavior and thinking due to the historical development of society in the process of social labor.
