, and between L vexillifer and Neophocaena phocaenoides is 15. 03%(49/326bp). Two phylogenetic trees, constructed by using sequence data, suggest that Lipotes vexillifer does not share a direct common ancestor with Inia geoffrensis, thus provide molecular evidence in favor of the establishment of family Lipotidae, extant river dolphins might be a group of species with

系统发育分析结果表明：白暨豚与亚河豚没有直接共同的祖先，从而为白暨豚科的建立提供了有利的分子证据；现存的淡水豚类可能仅是外形上相似的物种群，Muizon（1984，1988a，1988b，1990）关于各类淡水豚分属于不同的总科的建议，从分子进化的角度看是完全可能的：抹香鲸类可能是最早从古鲸类中分化出来的类群。
