In 2016, a whole-genome DNA study suggested that all of the North American canids, both wolves and coyotes, diverged from a common ancestor 6,000–117,000 years ago. The whole-genome sequence analysis shows that two endemic species of North American wolf, the red wolf and eastern wolf, are admixtures of the coyote and gray wolf. [26] [27]
The coyotes from Alaska, California, Alabama, and Quebec show almost no wolf ancestry. Coyotes from Missouri, Illinois, and Florida exhibit 5–10% wolf ancestry. There was 40% wolf to 60% coyote ancestry in red wolves, 60% wolf to 40% coyote in Eastern timber wolves, and 75% wolf to 25% coyote in the Great Lakes wolves.
The hunting regulations regarding eastern coyotes have also impacted wolves in states that border eastern wolf territory, or states that have wolf populations, because of the large size of eastern coyotes compared to western coyotes, and their genetic relations to wolves they can be mistaken for wolves and vice versa.
The red wolf's appearance is typical of the genus Canis, and is generally intermediate in size between the coyote and gray wolf, though some specimens may overlap in size with small gray wolves. A study of Canis morphometrics conducted in eastern North Carolina reported that red wolves are morphometrically distinct from coyotes and hybrids. [ 21 ]

Canids vary in size, including tails, from the 2 meter (6 ft 7 in) wolf to the 46 cm (18 in) fennec fox. Population sizes range from the Falkland Islands wolf , extinct since 1876, to the domestic dog, which has a worldwide population of over 1 billion. [ 1 ]

Canis is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails. [3]
