Social change may explain decline in genetic diversity of the Y chromosome at the end of the Neolithic period

History & Archeology

The emergence in the Neolithic of patrilineal 1 social systems, in which children are affiliated with their father's lineage, may explain a spectacular decline in the genetic diversity of the Y chromosome 2 observed worldwide between 3,000 and 5,000 years ago. In a study to be published on 24 April in Nature Communications, a team of scientists from the CNRS, MNHN and Université Paris Cité 3 suggest that these patrilineal organisations had a greater impact on the Y chromosome than mortality during conflict.
