Extended Data Fig. 3: Inter-specific phylogenetic trees of 12 major families of vertebrate-associated RNA viruses.
From: Farmed fur animals harbour viruses with zoonotic spillover potential

Phylogenetic trees were inferred for each family of RNA viruses based on amino acid sequences of the RNA-dependent RNA polymerase protein. All trees are midpoint-rooted for clarity and display bootstrap values for major branches. Coloured dots represent viruses with different host origins. The scale bar represents the number of amino acid substitutions per site.
