Divergence times and genome statistics of representative ray-finned fishes. a Divergence times of representative ray-finned fishes estimated using the topology obtained from the phylogenomic analysis (see Methods). The blue bars on ancestral nodes indicate the 95 % confidence intervals of divergence time estimates (MYA, million years ago). Numbers on each node represent bootstrap support values. b Genome statistics and (c) distribution of different types of orthologues in representative ray-finned fishes. The repetitive content of sunfish, fugu, Tetraodon, medaka, zebrafish, tilapia and stickleback were estimated in the present study (see Methods) whereas that for spotted gar is from Braasch et al.
