When did the concept of family start in human civilisation?

Answer 1

Clearly the biblical Jews believed in it:

Genesis 2:18 "It is not good for man to be alone, I shall make a help mate unto him."

Answer 2

Since the days of Adam and Eve, families have been a pivotal part of civilization. Children are taught within the confines of the family about being good citizens by caring and sharing with their siblings and following their parents rules. Those are the mainstays of society. When we learn to be good citizens in the family, it is easy for us to be good citizens in society at large. Adam and Eve were the prototypical parents and theirs was the prototypical family. That concept has been with us ever since.
Having said that, family units have been around from prehistoric times as evidenced in cave drawings in Europe and Asia. Anthropological evidence from Africa indicates family units there as well. Here in America, prehistoric evidence gives the same indication, though not as prehistoric as the other continents.

Answer 3

You'd probably be better off asking this question in an anthopology forum.

This said, since a concept of family exists in most great apes, it is likely that some sort of 'family' concept has been with us since our australopithecine days.

Answer 4

From the creation of the first man and woman there was a family, since the two got married and began to procreate.

But even before that, God provided a "model" for families in that He has always existed and His son Jesus Christ has always existed, so there was a Father/Son relationship that preceded even the earliest human relationships.

Answer 5

Your question is unclear. At least by the time of mammals' evolution is one answer. Another way to answer is that family evolved before humans, let alone civilization.
