[9], The canid family soon subdivided into three subfamilies, each of which diverged during the Eocene: Hesperocyoninae (about 39.7415 Mya), Borophaginae (about 3432 Mya), and Caninae (about 3430 Mya). The Canidae family is a group of carnivorous mammals that includes wolves, foxes, coyotes, jackals, and domestic dogs. 1.

Members of the family Canidae are known as canids, and may also be referred to as 'canines'. In most cases, groups have a home territory from which they drive out other conspecifics. Some canids are now endangered in the wild due to hunting, habitat loss, and the introduction of diseases from domestic dogs (IUCN 2007). The territory is marked by leaving urine scent marks, which warn trespassing individuals. Most experts believe the domestic dog is descended from an Asian subspecies of the gray wolf (Nowak 1983).

These species are all members of the Canidae family, which also includes domestic dogs. However, based on skeletal details of the neck, at least some of the Borophaginae (such as Aelurodon) are believed to have lacked this ligament.

These branches led to the borophagine and canine radiations. They also retain adult offspring in the social group, suppressing the ability of these to breed while making use of the alloparental care they can provide to help raise the next generation of offspring.

Some species will form packs or live in small family groups depending on the circumstances, including the type of available food. The three domains of life are currently divided into six kingdoms, one of which is Kingdom Animalia. A genus is a taxonomic category that ranks below family and above species in biological categorization. One study showed that foxes preferred areas that are more developed and manicured, such as residential neighbourhoods, athletic fields, and urban parks. Some foxes are valued for their pelts, which have been used in the fashion industry. [35] In most foxes, and in many of the true dogs, a male and female pair work together to hunt and to raise their young. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities.
