Golden jackal that can be represented as a phylogenetic tree. A 2005 genetic study of the canids found that the gray wolf and dog are the most closely related on this tree. The next most closely related are the coyote ("Canis latrans"), golden jackal, and Ethiopian wolf ("Canis simensis"), which have all been shown to hybridize with the dog in the wild. The next closest are the dhole ("Cuon alpinus") and African wild dog ("Lycaon pictus"), which are not members of genus "Canis". These are followed by the black-backed and side-striped jackals, members of genus "Canis" and the most basal members of
