Figure 1

Phylogeny of relevant species. A timescale is depicted in millions of years ago (MYA). The tree is a gross summary of references listed below, with reference 44 given particular importance. In our study the relative phylogeny of the species is more important than the exact times of separations, and we did not precisely calibrate time-scales between the referenced studies. Relevant literature for the respective branch knots [40-49] is indicated. Dotted lines relate to phylogenetic branch knots where the referenced literature was not informative on the absolute time of the event. Whole genome duplication events in a teleost ancestor (TGD), and early in the salmonid lineage (SGD), are indicated in red font.
