A jay is a member of a number of species of medium-sized, usually colorful and noisy, passerine birds in the crow family, Corvidae. The evolutionary relationships between the jays and the magpies are rather complex.
Not included in either tribe is the genus Urocyon, which includes 2 species, mainly comprising the gray fox and believed to be basal to the family. Additionally, one genus in Canini, Dusicyon , was composed of two recently extinct species, with Dusicyon avus going extinct around 400 years ago and the Falkland Islands wolf going extinct in 1876.
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.
This list of dog breeds includes both extant and extinct dog breeds, varieties and types. A research article on dog genomics published in Science/AAAS defines modern dog breeds as "a recent invention defined by conformation to a physical ideal and purity of lineage".
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]
The domestic dog is a divergent subspecies of the gray wolf and was derived from an extinct population of Late Pleistocene wolves. [ 8 ] [ 31 ] [ 32 ] Through selective pressure and selective breeding , the domestic dog has developed into hundreds of varied breeds and shows more behavioral and morphological variation than any other land mammal.
