When Barack Obama moves into the White House in January, he'll bring his wife and children with him. The nuclear family is not only as American as apple pie but also the cultural norm in most societies across the world. New genetic and chemical analyses of 4600-year-old burials in Germany suggests that family togetherness has deep roots, going back at least as far the beginnings of agriculture in Europe.
Before humans settled down and began to farm, they lived as nomadic hunters and gatherers. Many anthropologists have assumed, based on observations of sometimes polygamous modern-day hunter-gatherers, that the basic social unit of early humans was the band or tribe rather than the family. Figuring out when the nuclear family became central to human social organization has been difficult. Archaeologists have dug up thousands of skeletons at early farming sites across the Near East and Europe, and many of them are buried together in ways that might suggest family ties.
