Extended Data Fig. 7: An admixture graph connecting various modern meta-populations and ancient populations or individuals.
From: Palaeo-Eskimo genetic ancestry and the peopling of Chukotka and North America
The graph (see Supplementary Information section 10) features a simplified three-component model for Europeans as previously suggested37, and two gene flows from a European lineage related to the ancient Siberian genome MA-136 into Native Americans and Siberians. The topology within the PPE clade was obtained by cycling through dozens of trees with all possible topologies of branches and admixture edges, and selecting the one with the highest support and no zero-length edges within the PPE clade.
