Maximum likelihood tree of GbX, Ngb and several invertebrate globins. Maximum likelihood tree of GbX, Ngb and several invertebrate globins. Ngb sequences were included to root the tree. Numbers above branches correspond to bootstrap values, and those below to Bayesian posterior probabilities. Only Bootstrap values above 50% are shown. Branches of vertebrates are shaded in blue.
