Evolutionary distances for protein-coding sequences: modeling site-specific residue frequencies.

abstract：:The occurrence of a fish-specific genome duplication (FSGD) in the lineage leading to teleost fishes is widely accepted, but the consequences of this event remain elusive. Teleosts, and the cichlid fishes from the species flocks in the East African Great Lakes in particular, evolved a unique complexity and diversity o...
