Timing of the Emergence of the RFPL Genes during Evolution

The RFPL gene ancestor is shown in black. Each likely functional RFPL1, RFPL2, and RFPL3 gene is indicated in green, truncated genes are indicated in pink, and genes with no ORF are indicated in gray. Putative baboon RFPL1 gene is indicated in a dashed line. The RFPL4,5,6 gene cluster is represented by a single purple line. The estimated time of the gene-ancestor emergence and subsequent duplication events are indicated in millions of years (mya).
