“…Phylogenetic analyses reveal that the progenitors of ray-finned fish FLERVs co-diversify broadly with their fish hosts, but also suggest that there might have been several ancient viral cross-class transmissions, involving
lobe-finned fish, shark, and frog FLERVs. Again, by using the power-law rate-decay model, analyses in this thesis suggest that this major retroviral clade has an ancient Ordovician marine origin, originating together with their jawed vertebrate hosts more than 450 million years ago. …”
