Figure 7

Putative entry date of syncytin-Ory1 during lagomorph evolution. Schematized phylogenetic tree with the evolutionary timeline of four lagomorph genus (adapted from [16]) and the rodent and primate outgroups depicted, with average divergence times indicated for the nodes. The presence of syncytin-Ory1 sequences in each genus, detected either by PCR experiments (a) or database screening (b), is indicated on the right.
