Final answer:
Social Status has not traditionally served as a function of the family according to George Murdock's survey of societies, which found sexual, reproductive, educational, and economic functions as the universal residual functions of the family.
Step-by-step explanation:
The function that has not traditionally served as a part of the family's role is Social Status. Sociologist George Murdock surveyed 250 societies and identified four universal residual functions of the family: sexual, reproductive, educational, and economic functions.
These include regulating sexual relations between individuals, providing a legitimate outlet for those relations leading to reproduction, educating family members, and contributing to economic support. Social status, while possibly influenced by one's family, is not considered one of the direct, traditional functions families are meant to fulfill.
