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] The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. [ 2 ]
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.
The Caninae are known as canines, [6] and include domestic dogs, wolves, coyotes, foxes, jackals and other species. Canids are found on all continents except Antarctica , having arrived independently or accompanied by human beings over extended periods of time.
The explanation proposed for this mito-nuclear discord is that mitochondrial DNA introgression occurred from an ancient ancestor of genus Canis into the lineage that led to the black-backed jackal around 6.2–5.2 million years ago.

The study found that three ancient Belgium canids (the 36,000 YBP "Goyet dog" cataloged as Canis species, along with two specimens dated 30,000 YBP and 26,000 YBP cataloged as Canis lupus) formed an ancient clade that was the most divergent group. The study found that the skulls of the "Goyet dog" and the "Altai dog" had some dog-like ...
An all-time low was reached in 1967, when the population was reduced to 1,550 animals. The extirpation of wolves in Bulgaria was relatively recent, as a previous population of about 1,000 animals in 1955 was reduced to about 100–200 in 1964. In Greece, the species disappeared from the southern Peloponnese in 1930.
