Genealogical relationships among Gasterosteidae (Teleostei: Gasterosteiformes) were tested with 84 morphological, 48 behavioral, and 2879 molecular characters. Phylogenetic analysis of the combined data set identified a single (CI = 0.735) best‐supported hypothesis ( Spinachia ( Apeltes (( Pungitius + Culaea )( Gasterosteus aculeatus + G . wheatlandi )))). This hypothesis is identical to previous phylogenetic propositions proposed on the basis of behavioral, and behavioral plus morphological data. Our hypothesis, however, differed from a molecular‐based phylogeny in the placement of Apeltes . This analysis highlights the importance of combining all available evidence in order to produce the best‐supported proposition of genealogical relationships.
