Molecular phylogenetic tree constructed by NJ method suggests that African wild dog is the earliest divergent. Wolf, dog, and simien fox which belong to genus Canis are combined into one branch which diverged earlier than raccoon dog, red fox and blue fox. Red fox is more related to blue fox than the other animals.

NJ法构建的分子系统树显示，非洲野犬最先从犬科动物中分化出来；犬属的狼、狗和西门豺等3种为系统树上独立的一支，且其分歧的时间较赤狐、蓝狐和貉早；赤狐和蓝狐具有较近的亲缘关系。
