From: Proteomics computational analyses suggest that the bornavirus glycoprotein is a class III viral fusion protein (γ penetrene)

Figure 4

Acquisition of class I or III VFP by members of the order Mononegavirales. Thick lines indicate primordial lineages and thin lines are lineages leading to contemporary viruses. The alternative in Panel A shows a tree that is rooted, with the glycoproteins of all viral families evolved from a common class I, II and III progenitor. Panel B shows another possible evolutionary tree, which is unrooted, and depicts independent acquisitions of class I VFP by an ancestral paramyxoviruses and class III VFP of a common ancestor of rhabdoviruses and bornaviruses. A variation of this former tree (not shown) would involve separate acquisitions of class III VFP by ancestral rhabdoviruses and bornaviruses.
