Extended Data Fig. 8: TreeMix phylogeny of ancient and modern tigers.

Samples were grouped by modern subspecies or ancient RFE population. South China tigers with admixed ancestry were assigned as a separate group (AMO_MIX). Migration edges (m) were inferred from 0 to 7. The migration band inference results were similar to the results for gene flow and population admixture obtained with D-statistics and admixture graph modeling. We used the topology with 7 inferred migration bands for further demographic history modeling.
