Alpha tubulin genealogy. Bayesian reconstruction of insect alpha tubulin evolutionary relationships. Eighty-four tubulins were analyzed with Homarus americanus (Crustacea, Decapoda) alpha tubulins as the outgroup. There are four alpha tubulin clades ancestral to insects, the posterior probability scores in support of these clades are in larger font in the figure: α1 (0.68) which contains numerous polytomies; α2 (0.95); α3 (1.0) present in Bombyx and Tribolium; and α4 (0.97).
