Step-by-step explanation:
Functionalism, also called structural-functional theory, sees society as a structure with interrelated parts designed to meet the biological and social needs of the individuals in that society. It grew out of the writings of English philosopher and biologist Herbert Spencer, who argued that society functions like the various organs of the human body. Social stratification, a concept studied in sociology and social studies, is understood in functionalist theory as playing a role in assigning jobs to the most qualified individuals.
