By 40 Mya, the first identifiable member of the dog family had arisen. This family is represented by 14 genera and 34 species. A genus is a taxonomic category that ranks below family and above species in biological categorization. Canidae Family. The Advent of Canine Population Genomics", "Rethinking dog domestication by integrating genetics, archeology, and biogeography", "Complete mitochondrial genomes of ancient canids suggest a European origin of domestic dogs", "Genome sequencing highlights the dynamic early history of dogs", "Co-evolution of humans and canids: An alternative view of dog domestication: Homo homini lupus? The canines that are strictly carnivorous tend to hunt in packs; those that are omnivorous tend to be solitary in their hunting habits.

Another important natural role is the eating of dead animals, which they can easily find with their keen sense of smell. They are kept in a den, most often dug into the ground, for warmth and protection. Many species are viewed as pests to humans, and populations of many species have been decimated. Canidae is a family from the Carnivora order. Their senses of hearing and smell are especially acute. Canids vary in size from the 2-metre-long (6.6ft) gray wolf to the 24-centimetre-long (9.4in) fennec fox.

The time of year in which the breeding season occurs is related to the length of day, as has been demonstrated in the case of several species that have been translocated across the equator to the other hemisphere and experiences a six-month shift of phase. The cubs remain in the den for about five weeks and are cared for by both parents throughout the summer. With such variety, it is easy to see why there are so many different sizes. Mammal Evolution, an Illustrated Guide. 1979. Hairs grow between the pads and in the Arctic fox the sole of the foot is densely covered with hair at some times of the year. [41] Most canid species are spontaneous ovulators,[42] although maned wolves are induced ovulators. Most have a uniform coloration, although there are some contrasting colours on jackals and the gray fox, a dark mask on the raccoon dog, a blotching of black, yellow, and white on the African hunting dog, and a lighter-coloured belly in most species.
