Biological functionalism is an anthropological paradigm, asserting that all social institutions, beliefs, values and practices serve to address pragmatic concerns. In many ways, the theorem derives from the longer-established structural functionalism, yet the two theorems diverge from one another significantly. While both maintain the fundamental belief that a social structure is composed of many interdependent frames of reference, biological functionalists criticise the structural view that a social solidarity and collective conscience is required in a functioning system. By that fact, biological functionalism maintains that our individual survival and health is the driving provocation of actions, and that the importance of social rigidity is negligible.
