Extended Data Fig. 7: Admixture modelling using qpAdm.
From: The population history of northeastern Siberia since the Pleistocene
a, Maps showing locations and ancestry proportions of ancient (left) and modern (right) groups. b–d, Ancestry proportions and fit for all possible two-way (b), three-way (c) and four-way (d) reference population combinations. Transparent shading indicates model fit, with lighter transparency indicating models accepted with 0.05 > P ≥ 0.01 in qpAdm. Numbers of individuals for source and target populations are given in parentheses.
