The coyote Canis latrans, wolf Canis lupus, and domestic dog Canis familiaris are all separate species. The three species have been known to interbreed with one another in very scattered populations around the united states. Some northeastern coyotes have been shown to have percentages of both domestic dog and the wolf showing solid evidence towards the three species interbreeding. The idea that the inability to breed with other species should be removed from defining what a species is using this coyote hybrid as a great example. The northeastern coyotes show evidence of gene flow and while it is similar to hybridization these coyote hybrids are not a separate species. These hybrid coyotes should not be seen as a perfect example of gene flow and how an animal may adapt the changing environment.
