Seven generations of a prehistoric family mapped with ancient DNA

A Neolithic farming community from 6,500 years ago in modern-day France was mostly one big family. DNA analysis of 94 individuals found at a burial site revealed that two-thirds were members of a single family that spanned seven generations. No half-siblings were uncovered, suggesting that monogamy was standard. And most adult women were not closely related to others in the group, which indicates that male descendants tended to stay put, whereas women moved around.
