What is physiological adaptation? How does it arise and what is its basis?

Physiological adaptation is adaptation in the vital processes of organisms that help them survive in a particular habitat. If an organism finds itself in an unfamiliar environment or the habitual environment changes dramatically, then these adaptations become unnecessary and are no longer able to help survival. For example, let’s take the structure of the teeth of gophers. Rodents don’t have fangs because they don’t need them. They eat solid food and wear off incisors, which grow back repeatedly throughout their lives.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
