a, Geographic locations of newly sampled archaeological sites (filled, coloured symbols) from the Loess Plateau of Northern Shaanxi Province to Southern Shanxi Province, China. Purple symbols represent the geographical sites of previously published ancient samples from northern, western and central East Asia. b, Temporal distribution of new samples with direct radiocarbon dates from the Middle Neolithic (MN) to Late Neolithic (LN) and the Bronze Age (BA). Colours and symbols correspond with those in the geographic map. c, PCA projecting ancient samples (coloured) onto the genomic variation observed in Eurasian present-day humans (grey circles). Here cEA refers to the cline of central East Asians and Deep/wEA refers to the cline of Deep Asians/West East Asians. Yumin-related outliers are encircled by a dashed line and marked as Yumin cline. d, PCA analysis projecting ancient samples (coloured) onto the genomic variation observed in East Asian present-day humans. The sEA and Yumin clines are shown by dashed circles. The symbols are the same as c.
