Fig. 4: Co-phylogenetic analysis of hosts and betaherpesviruses reveal co-evolution across mammals.

Co-phylogeny of host species (phylogeny extracted from the mammalian super tree71) (left) with BHV, based on viral nucleotide (a) and amino acid (b) sequences. The lines between trees show links between virus and host phylogenies and are coloured by host family. Link weight is inversely proportional to the PACo squared residual for each species; heavier lines therefore reflect the likelihood that a pair represents a co-evolutionary link.
