Fig. 1From: Heterogeneous natural selection on oxidative phosphorylation genes among fishes with extreme high and low aerobic performancePhylogeny and swimming performance states of fish groups examined in this study. Swimming performance was reconstructed with parsimony (shown), as well as maximum likelihood, which was qualititatively similar, with outgroups from Betancur-R et al. (2013). Branch colors represent performance levels as follows: white, low performance; green, moderate performance; black, high performanceBack to article page
