They are our enemies, and so we marry them.

Family systems, like biological organisms, evolve with time and circumstance. Indeed, form may follow function. My anthropological colleagues observe how the nuclear family form is found at both ends of stages of economic evolution, predominating in societies with primitive hunting and gather economies where food supply is uncertain, and in modern industrial societies where the marketplace requires the geographical mobility of small, nuclear systems. Further, over the past two centuries the family has metamorphosed from being a unit of production to being a unit of consumption.
Key concepts: familial structures of obligation and aid; endogamous and exogamous rules of mate selection; polyandrous, polygynous, and monogamous unions; extended vs. nuclear forms; matrilineal and patrilineal descent systems; matrilocal, patrilocal, and neolocal residence rules; matriarchal and patriarchal authority systems; adult-child relationship rules and matters of legitimacy; dowries; primogeniture and ultimogeniture inheritance rules. If you want to see how these attributes correlate with each other in preindustrial societies using the Ethnographic Atlas, check out the Centre for Social Anthropology and Computing at the University of Kent at Canterbury.
In this era of rampant divorce, reports of family violence, and dramatic change in family roles and role relations, many reflect nostalgically back to "the good old days" of family life when, supposedly, familial bonds were richer and familial processes were less likely to be "dysfunctional."
Among the fallacies and dangers of such envisionments, members of this class

In his Family Discussions: Sociological Perspectives of Changing Families site, Professor Edward J. Steffes has provided excellent reviews of the following influential works that challenge the "supposed" history of families:

Another window on the family past is through oral histories. Resources to check include the Federal Writers' Project's "American Life Histories," oral histories collected between 1936-1940 and now part of the Library of Congress's American Memory website. Another site is Paul Thompson's "Family Life and Work Experience Before 1918: An Oral History Research Project."
The nineteenth century was a time when there still was faith in the perfectibility of man, which was, in turn, seen accomplishable if he were to be placed in the "correct" social environment. This was an era of great social experiments. New societies required new families which required, in part, new relations between the sexes and between children and adults. Among the most interesting and long-lived of these experiments was the Oneida Commune, which featured communal property and group marriage.
