a, Spatial distribution of kinship organization in global populations, adapted from D-PLACE61,62 and in the literature. Kinship structures in ancient populations are represented using different colours and symbols, which differentiate various types such as matrilineal and patrilineal systems across different regions and time periods. The world map was created using the R package maps (v3.4.2). b, Geographic location of the Fujia archaeological site in relation to the marine incursion around 6,000 years before present. Surrounding archaeological sites from the same period as Fujia, including Jiaojia (JJ), Dawenkou (DWK), Dongjiaying (DJY), Liangwangcheng (LWC), Xigongqiao (XGQ) and Beiqian (BQ), are marked to provide context. The base map was obtained from the Word Terrain Base domain map dataset (https://www.arcgis.com/home/item.html?id=c61ad8ab017d49e1a82f580ee1298931) and created with ArcGIS v10.2. Sources: Esri, USGS, NOAA. c, Painted pottery (bottom left) from the Fujia cemetery, as well as from the southern grave (FJ_S21; middle left) and northern grave (FJ_N07; top left). The right panel illustrates the layout and features of the Fujia archaeological site, highlighting residential areas, pottery kilns and the two cemeteries. Scale bar, 50 m.
