The research published on Thursday in Nature presents the first direct genetic evidence regarding the origins of the Shimao population — the builders of Shimao, a massive Neolithic walled settlement in northern China that thrived around 4,300 years ago and was abandoned about 500 years later.
The findings, based on genetic analysis of ancient individuals, offer a glimpse into the kinship practices, including sex-specific sacrificial rituals, of an early state-level society in East Asia.
The 4-million-square-metre Shimao city is the largest known prehistoric settlement in China. Its sophisticated fortifications, including pyramid-like platform, cyclopean stone walls, palatial complexes and stone carving, along with high-status artifacts like exquisite jades, point to a highly complex, stratified society.
