Molecular divergence and phylogeny: rates and patterns of cytochrome b evolution in cranes.


Analyses of complete cytochrome b sequences from all species of cranes (Aves: Gruidae) reveal aspects of sequence evolution in the early stages of divergence. These DNA sequences are > or = 89% identical, but expected departures from random substitution are evident. Silent, third-position pyrimidine transitions are the dominant substitution type, with… (More)
