Only two of four chimpanzee subspecies (Pan troglodytes), P. troglodytes troglodytes (P.t.t.) and P. troglodytes schweinfurthii (P.t.s.), appear to carry specific simian immunodeficiency viruses (SIVs). We identified genomic features indicating that SIVcpzPtt and SIVcpzPts may have partly different evolutionary histories. A maximum likelihood test to discriminate between hypotheses of a common versus separate origin of SIVcpzPtt and SIVcpzPts revealed three putative regions of separate histories. Thus, after the P.t.t. and P.t.s. split, SIV superinfection led to further recombination resulting in the emergence of SIVcpzPts. This shows that there have been multiple SIV transfers to chimpanzees at different times in their evolution.
