文摘
- •
Circovirus phylogeny parallels host phylogeny with early host-switching between avian and mammalian viruses.
- •
High mutation signals in contemporary viruses can grossly underestimate evolutionary timescales.
- •
Emphasises Australia and New Guinea as an evolutionary hotspot for avian circovirus evolution.
- •
Highlights the cryptic effects of population genetic structure, selection pressure and recombination on phylogeny.
- •
We demonstrate a deep host-history phylogenetic basis for contemporaneous virus host-switching.
