Rooted Bayesian inference for gag gene. Numbers close to branches indicate posterior probability values above 0.50. Numbers close to names correspond to different clones. Black symbols represent ERVs from the different Eurasian species and gray symbols represent ERVs from different African species (see legend for detail in coding). Outgroup branch is not to scale.
