Maximum-likelihood tree of KCNA genes rooted by invertebrate sequences. 203 amino acid sites were employed in this analysis. Statistical support values for nodes with branches leading to sea lamprey and elephant shark genes are shown with ML bootstrap values left to the slash and posterior probabilities right to the slash. "-" indicates inconsistent tree topologies between Maximum-likelihood tree and Bayesian tree.
