Figure 5

Model of evolution of the AR in fish based on the same phylogenetic background as Figure 1. A WGD occurred at the base of the Teleostei, and two successive losses occurred in the lineages leading to the Otophysi and the Oncorhynchus. Last, in the percomorphs, all the AR-B genes harbor an event of acceleration, while the AR-A ones show no sign of such rapid evolution at the molecular level.
