| ARTICLES RELATED TO Molecular systematics | | | |  Molecular systematics: Encyclopedia II - Dog - Spaying and neuteringDog experts advise that dogs not intended for further breeding should be spayed or neutered so that they do not have undesired puppies. Unwanted puppies are abandoned, eaten, or sometimes disposed of in an inhumane fashion. It is also common for adult stray dogs who are placed in animal shelters to be euthanized due to lack of space and resources. Spaying and neutering can also help prevent hormone-driven diseases such as breast cancer and prostate cancer, a ...

| | | | | Molecular systematics: Encyclopedia II - Dog - Terminology Dog, in common usage, refers to the domestic pet dog, Canis lupus familiaris (originally classified as Canis familiaris by Linnaeus in 1758, but reclassified as a subspecies of the wolf, Canis lupus, by the Smithsonian Institution and the American Society of Mammalogists in 1993). The word is sometimes used to refer collectively to any mammal belonging to the family Canidae (as in "the dog family"), such as wolves, foxes and coyotes.

| | | | | Molecular systematics: Encyclopedia II - Dog - Diet Presently, there is academic discussion as to whether domestic dogs are omnivores or carnivores. The classification in the Order Carnivora does not necessarily mean that a dog's diet must be restricted to meat. Unlike an obligate carnivore, such as a cat, a dog is not dependent on meat protein in order to fulfill its dietary requirements. Dogs are able to healthily digest a variety of foods including vegetables and grains, and in fact can consume a large proportion of these in its diet. Wild canines not only eat available plants to obtain ke ...

| | | | | Molecular systematics: Encyclopedia II - Scientific classification - Group suffixes Taxa above the genus level are often given names derived from the Latin (or Latinized) stem of the type genus, plus a standard suffix. The suffixes used to form these names depend on the kingdom, and sometimes the phylum and class, as set out in the table below.
Notes
The stem of a word may not be straightforward to deduce from the nominative form as it appears in the name of the genus. For example, Latin "homo" (human) has stem "homin-", thus Hominidae, not "Homidae".
For animals, there are standard suffixes for taxa on ...

| | | | | Molecular systematics: Encyclopedia II - Dog - Ancestry and history of domestication Molecular systematics indicate that the domestic dog (Canis familiaris) descends from one or more populations of wild wolves (Canis lupus). As reflected in the nomenclature, dogs are a subspecies of wolf and are thus still able to interbreed.
The relationship between man and canine has deep roots. Wolf remains have been found in association with hominid remains dating from 400,000 years ago. Converging archaeological and genetic evidence indicate a time of domestication in the late Upper Paleolithic close to the Pleistoc ...

| | | | | Molecular systematics: Encyclopedia II - Dog - Dog breeds There are numerous dog breeds, over 800 being recognized by various kennel clubs worldwide. As all dog breeds have been derived from mixed-breed dog populations, the term "purebred" has meaning only with respect to a certain number of generations. Many dogs, especially outside the United States and Western Europe, belong to no recognized breed.
A few basic breed types have evolved gradually during the domesticated dog's relationship with man over the last 10,000 or more years, but most modern breeds are of relatively recent derivation ...

| | | | | | Molecular systematics: Encyclopedia II - Molecular systematics - Example: the phylogeny of the domestic dog For example, Vilà et al (1997) determined haplotypes from a sequence of 261 base pairs in the mitochondrial DNA of 140 domestic dogs, 162 wolves, 5 coyotes, and 10 jackals (of three different species). The dogs were drawn from 67 different pure breeds and 5 cross breeds, and the wolves were drawn from 27 distinct geographically defined populations. The coyotes and jackals were used as the out group.
Vilà et al found 27 distinct haplotypes among the wolves, and 26 among the dogs. The wolf haplotypes differed from each other by no mor ...
