a, The proportion of the genomes of individual brown bears derived from admixture with cave bears, following the divergence of brown bears and polar bears (f̂results). Eighteen admixture estimates per brown bear represent all possible combinations of European cave bear introgressor, relative to three polar bears. Almost all values are strongly significant (Z > 3). A small number of comparisons involving the Russian and American bears were more moderately supported (Z > 2.4). ABC, Admiralty, Baranof and Chichagof Islands; Den., Denali; LP, Late Pleistocene. b, The proportion of the genomes of individual European cave bears derived from admixture with brown bears, following the divergence of the European cave bear clade and the Caucasus cave bear kudarensis (f̂results). Twenty dots per cave bear sample represent all possible combinations of modern Eurasian brown bear introgressors. All comparisons involving eremus are at least moderately supported (Z > 2), but 30% and 70% of comparisons involving ingressus and spelaeus, respectively, fell below this threshold (indicated by open circles).
