Canis
A genus of canids including wolves, dogs, coyotes, and jackals.
Canis is a genus within the subfamily Caninae that includes several extant species such as wolves, dogs, coyotes, and golden jackals. Species of this genus are characterized by moderate to large size, massive well-developed skulls and dentition, long legs, and comparatively short ears and tails. The genus was published by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae and has been the subject of extensive taxonomic and evolutionary study.

Lore & Background
The genus Canis was established by Carl Linnaeus in 1758 and originally included dog-like carnivores: domestic dog, wolves, coyotes, and jackals. All species within Canis are phylogenetically closely related, possess 78 chromosomes, and can potentially interbreed.
Reader's Guide
The genus Canis holds significant importance in evolutionary biology and paleontology. The fossil record indicates that caniforms emerged within Carnivoramorpha 43 million years ago, with the fox-like genus Leptocyon branching into Vulpes and Canini 11.9 million years ago. The jackal-sized Eucyon existed in North America from 10 million YBP and gave rise to early North American Canis by the Miocene (6 million YBP). Around 5 million YBP, Canis lepophagus appeared in southwestern United States and Mexico, while Old World Eucyon evolved into the first members of Canis. The wolf-sized Canis chihliensis appeared in northern China around 4-3 million YBP, followed by an explosion of Canis evolution across Eurasia in the Early Pleistocene (the 'wolf event'). True members of Canis, such as the gray wolf and coyote, likely arrived in the New World only during the Late Pleistocene. The genus also includes the extinct subgenus Xenocyon, which gave rise to the modern dhole and African wild dog.
