according to the davis-moore thesis what is a role of social stratification
Davis–Moore hypothesis The hypothesis is an attempted explanation of social stratification, based on the idea of "functional necessity". Davis and Moore argue that the most difficult jobs in any society are the most necessary and require the highest rewards and compensation to sufficiently motivate individuals to fill them. Once the roles are filled, the division of labour functions properly, based on the notion of organic solidarity advanced by Emile Durkheim.[1]
Nature versus nurture The phrase in its modern sense was popularized by the English Victorian polymath Francis Galton, the modern founder of eugenics and behavioral genetics, discussing the influence of heredity and environment on social advancement.[5][6][7] Galton was influenced by the book On the Origin of Species written by his half-cousin, Charles Darwin.
