Extended Data Fig. 4: D statistics calculated for tree topologies relating different genome trios.

On the left, the different tree topologies tested (a–g). IL= Iberian lynx, EL= Eurasian lynx. Western EL included genomes sampled in Kirov, Caucasus, Balkans and Carpathians, while Eastern EL genomes were sampled in Primorsky Krai and Yakutia. All topologies were tested using the domestic cat as the outgroup. Red and white points show significant and non-significant D values, respectively. The seven different tree topologies tested (a–g) are displayed for each category of D values shown, with double-headed arrows indicating the admixing lineages supported by significant tests. a shows similar introgression in different contemporary IL individuals. b and c show similar and non-significant d-stat when different eastern and western Eurasian lynx individuals are compared. d and e show higher admixture signal from contemporary Eurasian lynx than from a single ancient Eurasian lynx from the Iberian Peninsula, whereas ancient Iberian lynx is less admixed with ancient EL than contemporary Western EL (F) and similarly than Eastern EL (G).
