Can it be argued that the biological evolution of modern man has completely stopped?

No, you can’t, she keeps going.
Evolution is an ongoing process, and therefore, for the species Homo sapiens, it has not stopped. Evolution has moved to another level. A person adapts to new conditions of life, physical labor becomes less important and widespread. In connection with the weakening of biological factors and an increase in social, a person will undergo changes both external and internal, which is exactly – this is a matter of time, the answer to which scientists are looking for today.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
