Figure 2. The best-scoring maximum-likelihood (ML) tree derived from the concatenated supermatrix of the 274 nuclear genes (90,646bp, excluding the third codon positions) from the 26 actinopterygians with the GTRGAMMA model implemented in RAxML.

Numbers besides internal branches indicate bootstrap values based on 100 replicates. Other phylogenetic tree reconstruction strategies implemented in this report all obtained the same topology as this and are shown in supplemental Figure S1.
