## Figure 4.
A clade credibility tree showing the relationships between lungfish and other selected
vertebrate opsins. The tree was generated using Bayesian inference
via a Metroplis-coupled Markov chain Monte Carlo simulation. Sarcopterygian fish (coelacanth
and lungfish) are in red, teleost fish are in blue, amphibians are in green and reptiles
are in maroon. Genbank accession numbers are listed in Table 1. Posterior probability
values are at the base of each node. The rh4 opsin of Drosophila melanogaster is used as an outgroup (Table 1). The probability of most relationships within the
tree is 1.00 after 300,000 generations, while lower posterior probability values are
found within the lws and rh1 groups.
