Evolutionary history of retroviral elements in mule deer. Median time to most recent common ancestor (tMRCA) estimated under Yule process speciation model, relaxed clock, and TVM+Γ nucleotide substitution model. Support for nodes only shown if posterior probability >0.50, and CrERV lineages are designated I–IV. CrERVs were absent in white-tailed (WT) deer with the exception of CrERV-in14. Median estimates of node age (black diamonds) and 95% highest posterior probability densities shown in insert with color used to highlight corresponding lineage. Branch widths represent relative evolutionary rate with thicker branches undergoing more rapid evolution.
