Relative divergence time estimates for simian foamy virus (SFV) polymerase sequences inferred using Bayesian phylogenetic analysis. An alignment of 341 nucleotides from 31 taxa was used in the analysis. New sequences generated in the current study are in blue text. Posterior probabilities ≥0.7 are provided at nodes. Scale for divergence date estimates is in 1 million years with blue dashed lines every 10 million years. aca Alouatta caraya, ase Alouatta seniculus, agu Alouatta guariba, abe Alouatta belzebul, asp Ateles species, cme Cajacao melanocephalus, cja Callithrix jacchus, cxa Cebus xanthosternos, cap Cebus apella, cro Cebus robustus, lro Leontopithecus rosalia, lch Leontopithecus chrysomelas, csp Chiropotes species, cge, Callithrix geoffroyi, ssc Saimiri sciureus, sus Saimiri ustus, ssp Saimiri species, csp Chlorocebus species, ptr Pan troglodytes
