That men stayed in their parents' homes and women went to other families' homes seems to be a constant in prehistory. A few weeks ago it was published the largest family tree of the Neolithic with almost a hundred members excavated in France. In the two clans studied, the women came from outside. Now, in the extreme east of the continent, they have sequenced the genome of a family of shepherds made up of six brothers, their seven wives, children and grandchildren. Their partners were also outside the community. In this collective burial there is a mystery: there are no women genetically related to men, except for little girls.
