FIGURE 10.3 Character mapping of L photopigment λ_max values onto an L opsin gene tree. Numbers shown above branch indicate maximum-likelihood bootstrap support values and numbers below branch show Bayesian clade credibility values. Thick black lines indicate nymphalid branches along which blue spectral shifts occurred that were investigated in the parallel/convergent change and branch-site tests of selection. Extant blue-shifted sequences are underlined. Nodes in which ancestral state reconstructions shown in Table 10.3 were performed are indicated by letters.
