In phylogenetic analyses, conducted on the ND4L gene and part of the ND4 gene from species of the genus Pimephales , maximum parsimony yielded four trees, with the strict consensus providing no resolution of relationships among species. Maximum likelihood and minimum evolution methods yielded identical tree topologies, which differed from previous hypotheses of relationships for these species. If this topology is correct, it implies independent evolution of morphological characters, possibly associated with convergent trophic specialization.
